What is RAID?

Residual information is also ored for the data in this disk array. The redundancy information consists of direct parity (parity) and parity information calculated based on various data blocks (RAID 4 or RAID 5). When RAID is used, the operating system (Windows *, NetWare *, or Unix) is interested in the same disk array that it sees as a single logical drive, rather than dealing with individual disks.

The main purpose of RAID arrays is to improve data availability and security. RAID prevents the system from going off when there is a hard drive failure, but it can not recover data that has been deleted by the user or damaged by an important event such as theft or fire. For this reason, after installing a RAID system, you must back up your data regularly to ensure that your system is protected against such problems.

There are two ways to put a RAID solution into practice. The hardware-based RAID controller is a smart component and can handle all RAID information on its own. If you set up such a system, the RAID controller takes over the entire control load of the RAID array instead of the host. The other method is to use a RAID solution that includes a RAID driver and a simple host adapter. In such systems, the drive is integrated with the operating system (for example, Windows * NT). Therefore, the performance of the RAID system is entirely dependent on the processing load of the host CPU, and you may experience problems recreating the array after a disk failure.

When choosing a hardware RAID RAID controller, you should be aware of the following points: ease of installation and maintenance, management software features, and the manufacturer's experience in developing RAID components. Supporting the most important RAID levels (0, 1, 4, 5, 10) of the RAID controller should be able to handle arrays running on multiple channels and different RAID levels at the same time.

RAID Levels - How to edit drives

Each RAID level distributes the data in a different format to the drives in the row and is optimized for certain situations. This document discusses the most common RAID levels used today.

Detecting your RAID level

RAID 0

At this RAID level, two or more hard drives are combined to share manageable blocks (ABCD ... in yellow cylinders) from the user. These blocks are distributed by striping to different drives in the RAID 0 array. As a result, two or more hard drives are combined and better read / write performance can be achieved, especially for sequential access. However, redundancy information is not stored in the RAID 0 array. In other words, if one of the hard disks fails, all the data is lost. A 0 in the RAID level indicates that this level does not contain redundancy. This is usually why RAID 0 is not used on servers where safety is important.

raid_level_pic

Advantage: Provides the highest transfer rate Disadvantage: If a disk fails because there is no redundancy, all the data is lost Uses: Usually used in workstations to store temporary data and to achieve high I / O rate

RAID 1

In RAID 1 systems, the same data is stored on two hard disks (100% redundancy). When one of the disks fails, immediate use is offered without affecting the performance of the other disk drive system or the integrity of the data. When two disk drives are mirrored over a SCSI channel, this is called "Disk Mirroring". If each of the disk drives is connected to a different SCSI channel, it is called "Disk Duplication" (provides additional security). RAID 1 is an easy and highly effective solution for data security and availability.

Advantage: High availability, Logical Drive with data can be used even if a disk fails Disadvantage: Requires 2 disks, but only one can use the storage capacity Uses: Used in small systems and boot disks where a diskin capacity is usually sufficient Raid Configurations. What is Raid 0, Raid 1, Raid 4, Raid 5, Raid 10? How ?

RAID 4

RAID 4 is similar to RAID 0 in large measure. The data is distributed to the disk drives by the taping method. In addition, the redundancy information stored on another disk drive (P1, P2, ...) is calculated via the RAID controller. Even if one of the disks fails, all the data is available. Missing data are calculated with the help of available data and accompanying information. Unlike RAID 1, only one disk drive's capacity is used for redundancy. For example, in a RAID 4 disk array with 5 disk drives, 80% of the installed disk drive capacity is used as user capacity and only 20% is allocated for redundancy. If there are numerous small data blocks in the system, the accompanying disk can cause a bottleneck in terms of job production. In situations where large data blocks are used, RAID 4 provides a significant performance boost.

Advantage: High availability, Logical Drive with data can be used even if a disk fails Advantage: Allows you to use the disk capacity very well (n-1 disk is used for storing data in a discrete array) Disadvantage: Write performance is limited because it is necessary to calculate redundancy information Uses: It is often used in large systems for data storage because of the very good ratio of installed capacity to available capacity

Raid Configurations. What is Raid 0, Raid 1, Raid 4, Raid 5, Raid 10? How ?

RAID 5

The parity information in the RAID 5 disk array is distributed to all disk drives, unlike the RAID 4 array. The RAID 5 disk array allows you to achieve a more balanced job production. It provides a very good response time, even for small blocks of data that are common in many users' environments where multitasking is used. The security level of RAID 5 is the same as RAID 4: even if one of the disks fails, all the data is available. Missing data are recalculated with the help of available data and accompanying information.

Advantage: High availability, Logical Drive with data can be used even if a disk fails Advantage: Allows you to use the disk capacity very well (n-1 disk is used for storing data in a discrete array) Disadvantage: Write performance is limited because it is necessary to calculate redundancy information Uses: It is often used in large systems for data storage because of the very good ratio of installed capacity to available capacity

RAID 10

RAID 10 is the combination of RAID 0 (Performance) and RAID 1 (Data Security). Unlike RAID 4 and RAID 5, parity information does not need to be computed. RAID 10 disk arrays provide good performance and data security. As with RAID 0, the best performance is achieved in sequential loads. Similar to RAID 1, 50% of the installed capacity is spent for redundancy.

Advantage: High availability, Logical Drive with data can be used even if a disk fails Advantage: Good write performance Disadvantage: Requires at least four disks, and only half of this capacity can be used Field of application: Typically used in environments where sequential write performance should be high

How to view cPanel Error logs

cPanel states, "This capacity will show the last 300 blunders for your site. This can be extremely valuable for finding broken connections or issues with missing records. Checking this log regularly can help keep your site running easily." What this implies is the point at which your site is gone to by somebody, the server gets a demand from that guests program and area to your server. At the point when the guest hits a segment of your site and they cause a blunder, the mistake log will log the date, time, IP , page the blunder happened et cetera. These blunders could be brought about for various reasons. The following are a couple reasons why mistakes would be tossed. Page Alias Changed (SEF URL's or Permalinks changed) Document was erased or renamed SpamBots attempting to control a url Missing blunder pages or robots.txt Menu joins changed without diverting Old URLS reserved in web search tools There are many reasons your site could have blunders. Its a smart thought to check you mistake log habitually to fix web crawler issues that impact your internet searcher positioning and site usefulness.

cPanel Error log

You can find your cPanel Error log by following the steps below.
  1. Login into your cPanel.
  2. 4Go to Metrics > Errors.  Your error log will display in the box. See the image to the right.  Cpanel will display the last 300 errors through the Error log interface.

SSD versus HDD: Difference. Points of interest. What to decide for facilitating a site?

Above all else – we should not make this a fight – in light of the fact that it's most certainly not. We will investigate the distinction amongst SSDs and HDDs, and give our suggestions and discourse with respect to the distinctions, points of interest and innovation correlations. SSD_HDD Review of HDD and SSD innovation A HDD (or Hard Disk Drive) can be best envisioned as a vinyl player for your PC. It comprises of a metal plate with attractive covering that records your information. Like a vinyl, your PC has a perusing arm that floats over the turning hard plate – considering that information to be perused, exchanged and shown on your PC. The speedier the plate turns, the quicker it can perform – yet the greater part of this causes warm a rubbing – in the long run warming up your PC. The SSD (or Solid State Drives) offer a similar capacity of the HDD however at a more noteworthy level of productivity. SSDs are basically streak memory chips. Being that they are chips require no energy to "turn up," SSDs are more adaptable in size – taking into account organizations, for example, Apple to exploit them and turned out with such items like the Mac Book Air. As a similarity to whole up the distinction: Let's accept you live on a vast lake, and you have to get to the opposite side. Would it be speedier to push crosswise over with one oar, or to take a speedboat? In this relationship, think about the skiff as the HDD, and the speedboat as the SSD. Beyond any doubt you can push over, however the more you column, the more drained you get; though with the speedboat, you should simply wrench up the power. Tech Specs of SSD and HDD: initially Presently don't be befuddled. SSDs are not an entire pack of blaze drives (or thumb drives) that have been glued together on a circuit board. The hardware of the SSDs is a great deal more mind boggling. Be that as it may, maintaining a strategic distance from the techno-talk, the basic clarification is that SSD are extensive memory chips that don't section their information. HDDThe Fragmentation of information on a HDD fills in as it did in our vinyl relationship. Since your records are put away on a plate, and are composed on the magnets covering those circles, recovering that information takes a more drawn out to recuperate. While SSDs don't focus on where the information is put away. It appears as though HDDs are more composed in this sense by being spun in one region – however when you have a truly expansive document that can fit in on one circle, you disperse your information. This make s recovering that information take longer. SSDs don't do this as they store in what some contrast with as a "cloud" memory. Talking about discovering records, how about we address the document opening, replicating, and composing discuss both capacity units. Plainly, SSDs open, duplicate, and compose records beginning at 200MB every second. HDDs maximize something close to 120MB every second. Speed is won in this round by SSDs in light of the fact that they don't need to manage the turn up of plates or the previously mentioned fracture. Speed is incredible in case you're running Photoshop and need to finish various little assignments, or in case you're running a straightforward site. hard_disk_1 HDDWe said contact some time recently, so how about we discuss i. All things considered, consider it. A moving circle that needs to turn up to recover your documents will lead warm – it's simply material science. Particularly will that circle turn quicker with the more capacities that your HDD is advised to do. Turning bringing on grinding which causes warm. Won't not warm up your home amid winter, but rather for a limited space like the base of your portable workstation secured on two sides with 2 plastic boards – well how about we simply say you're taking a gander at a hot-beat rather than a tablet. What does that mean for you versus a business server? All things considered, more vitality is one. The more your PC works, the more fans it should be chilled off. The more blazing it gets, the slower it works. ON a desktop level while playing your most loved diversions – this ought to approve of all the standard components. Yet, in the event that you're running a server, or facilitating sites on that server as an organization, you wager your rear end will require something that doesn't warm up as quick which would thus back off your customers' sites and increment downtime. How about we get Physical Keep in mind that HDDs are turning plates. They physically (and actually – hello, why not both!) turn. So when there is a characteristic unsettling influence (not in the constrain but rather on your framework), it may influence the hard-drive. Ex. You're perched on your love seat and surfing the web on your portable PC. You move to connect to the charger and accidently drop your portable PC. Your first stress is the screen! "Gee golly!" Once you lift it up and see that nothing happened you victory a murmur of help. However, you're not thinking about the turning circles that have shaken up, broken, and even bowed. That is one f the provisos of the HDD. SSDs are strong state memory chips as we've examined – they don't turn or move. They are more secure to regular wonder and the incidental butterfingers that all PC clients have. Magneto! One element that you hear a considerable measure when SSDs and HDDs are analyzed is about the attractive covering on a turning circles and their affectability to magnets. Accepting you're absent with your portable workstation in the region of an EMP or you don't stick your PC in a MRI machine – you ought to be fine. Q.B.D! Quick.Break.Down Purchasing 1 TB of space: For a SSD, costs around $250 For a HHD, costs around $50 The HDD is the conspicuous financially agreeable purchase. SSD versus HDD: Summary Despite the fact that the cost of SSDs has been falling, the cost per gigabyte preferred standpoint is still firmly with HDDs. However, in the event that execution and quick bootup is your essential thought and cash is auxiliary, then SSD is the approach. No "buts," or "despite the fact that," or versus in this area. Basically, HDDs are your prudent "go-to" when the subject of information stockpiling are being referred to. SSDs are the champions with regards to speed, execution, and are the more costly choice. At last, it's about what you require more. To work a considerable measure of little errands in the meantime? At that point run with SSDs. In case you're hoping to work your PC utilizing a ton of projects and documents, and need to remain inside spending plan, run with HDDs. ssd SSD in Web Hosting Industry For whatever length of time that our site is generally identified with web facilitating, let us consider SSD and HDD circles appropriate to the business i.e. when they are utilized as a part of web servers intended to have a site. As it was specified above, when it is about your own web server (committed server facilitating) everything at long last goes to the cost of plates and the execution you'd get a kick out of the chance to accomplish utilizing either SSDs or HDD circles on your web server. SSD x20 fasterHowever, with regards to shared web facilitating or VPS facilitating the value that facilitating organizations offer for SSD facilitating is not for the most part altogether more than the cost of HDD facilitating, so that may be a smart thought to pick web facilitating with SSD circle bolster for sites that do many read-keeps in touch with the drive i.e. e.g. database driven locales, for example, gatherings, sites, Joomla based destinations, web based business locales, and so on.

What is Cron Jobs? Scheduled Task Creation and Samples

In this article, we will tell you the structure of Cron Jobs which is a very useful feature that is frequently used in the hosting sector. All other details such as usage structure, advanced examples and output results are still in the article. The examples we give expression during Hostgator which is built on shared hosting account cPanel control panel was carried out with.

Cron Job - What is a Scheduled Task?

The Linux operating system is a structure that is used in products such as Servers, Cloud Servers, Shared Hosting packages, VPS and Reseller packages and implements the task that you specify at the desired time and at any time you set. For example, you can perform operations such as backing up the database at X every day or sending an e-mail to one person, or running a script you set every 30 minutes with the Cron Jobs feature.

For advanced commands that require simple level script usage information for normal use, we will give some examples and detailed explanations about this feature, which requires the use of linux. Scheduled tasks play a crucial role in a healthy hosting. Even if you do not follow it, it's really important that the backplane is the part that works for you and controls the systems.

Using Linux Web Hosting and Cron Jobs on Servers

The action to take to use scheduled tasks. The server or hosting package will be entered into the control panel and clicked on the Cron jobs logos. The following image shows a Cron Jobs logo on a standard cPanel.

cron job

A form different for each hosting company it will come prepared to enter the region after. Since the information requested on the form is the same, you can use the following information easily.

1) E-Mail: first in a valid e-mail address to inform you about the output of the Scheduled Tasks monitored. With this method, you can check your e-mail accounts without entering your control panel and check if your cron job is working and working properly.

2) Auto Setup: that the operation should be done when you can choose pre-created with these settings. It is the time interval that users use the most and you do not have to use this part. You can make a more detailed adjustment of the Time and Date settings manually.

3.) Minute: Minute setting of the specified task. In this section, the task can be done every X minutes or once a day, but in minutes. You will see more detail in the examples section.

4) The time at which the task every X hours or time settings should work is set here.

5.) Day: Day adjustment.

6) Month: Task in which month or months or condition or not to perform every month.

7.) Week Day - Weekday: You specify which day or days of work and will not work on all days of the week or the command. 0 = Sunday and 6 = Saturday. Only numbers are written, numbered 0-6.

All of the sections described above are the sections that concern the duty cycle and time. After this section, the area where the command to be requested to be counteracted is entered will appear. Commander or what tasks specified in this section as a command line only way to determine whether and how they should work. Tasks and the way it works is as follows.

It is almost impossible to describe these operations individually using Shell commands. The main set of commands used here on Linux is also working here. We will soon be talking about these and the most commonly used commands and logic for working with you. In other cases, teaching the commands one by one is no different than teaching C language from scratch. If there are other commands that you want to apply on the subject, you can request it from our comments section.

Scheduled tasks are automatically sent to your e-mail address when the task is run. If you do not want to get this information, you need to add the following code at the end of the commands.

> / dev / null

Examples of this will be explained shortly.

The structure of the commands is somewhat similar to the use of MS Friendly tags. With the corresponding command, many operations such as file execution, creation, invocation, sending can be performed. Below you can see a simple example code that provides database backup.

Mysqldump -u mysql_user -psifre database_ismi> backup.sql

Mysqldump is used with a standard backup command in the example above. Here, you can backup the database name password and user name part by changing their information. Let's go to sample groups immediately.

Examples of Cron Job Time Adjustment

In the above section, we talked about the use of time. Now let's make more examples of these.

Example 1: every day at 8:25 (AM) for performing the operation specified TA

25 8 * * * /home/users/test.sh

Time usage has a hierarchy from left to right as Minute -> Time -> Day -> Month -> Week Day. In the above explanation, there is sample code of the operation to be executed every month of the year, every day and every day at 8:25 o'clock. Month, Day, and Weekday sections are marked with "*" to cover the whole Moon, Days. At the end of the code, the command "/home/user/test.sh" is the command we want to run. We'll just give you time examples here. Therefore, be sure to set the timing at the beginning rather than this command.

Example 2: Only Wednesdays 8:25 (AM) te code we want to run.

25 8 * * 3 /home/users/test.sh

As you can see, in this example, we write only part 3 which is Weekday, and only this process is done on Wednesdays.

Example 3: If we want the process to be performed at 8:00 AM and 16:00 PM every day time.

0 8,16 * * * /home/users/test.sh

Example 4: Transactions only if we want to be in on Mondays and 13:00 AM to 19:00 PM untill all the watches;

0 13-19 * * 1 /home/users/test.sh

This is done at the beginning of every hour of the time interval using the "-" sign.

Example 5: Each month, between 4 and 10 and let the process every 15 minutes.

* / 15 * 4-10 * * /home/users/test.sh

The "/" sign used in the above example is known as the repeat command. It was every 15 minutes because we used it under the minute portion. If we used / 2 under the hour part, the operation was done every 2 hours.

The time samples are understood according to our estimation. If you want to make different time samples about the topic, use our comments section for support.

Cron Jobs Command Examples

In this section, let's look at examples that are added to the end of the time command and that are the actual command part. These are the most common and most commonly used processes. All of the examples below are set to work at 12:00 hours per day. You can adjust this setting according to your preference according to the above information.

1.) Database Backup:

0 12 * * * mysqldump -u VERITABILITY_USER -pSIFRE VERITABANI_ADI> backup.sql

Replace capital letters with your own database information. Do not touch places that are written in lower case.

2.) Database Backup (Without E-Mail):

0 12 * * * mysqldump -u VERITABILITY_USER -pSIGRE VERITABANI_ADI> backup.sql> / dev / null

We have included the above code in the last line. The now scheduled task finisher will not be notified by email.

3.) Database Restore:

0 12 * * * mysql -u VERITABANI_USER -pSIFRE VERITABANI_ADI <backup.sql

Here, mysql command is used to restore the backup.sql backup to the database. In the event of a malfunction, this can be quite useful. Of course, all updates made in the database will be back to their original state.

4.) PHP Code Execution:

0 12 * * * php /home/users/public_html/ozel_kod.php

In the above command, the php code will start with the first command "php" and the code will be in the specified time zone of your server by defining the location of your server "ozel_kod.php".

5.) PERL Code Operation:

0 12 * * * perl /home/user/public_html/ozel_kod.pl

It works the same logic as PHP. Just start the code with perl and the extension ends in .pl.

6.) Making a query on a different website:

0 12 * * * / usr / bin / wget http://www.siteadi.com/ozel_kod.php

The command used to query a remote site "wget" command. Your hosting company will ask you if this code is set for you. Some companies can close this code at startup. The command line first specifies the extension of the wget function, followed immediately by the site and query extension to be used for the query. This query will occur at the specified time period and frequency.

7.) Find and delete files:

0 12 * * * find / onblock -type f -empty -delete

Find and un-delete commands are used above. You can use this command if you want to delete newly created files in your server or emptied some tmp folders at specified times. You can find files / folders that you want to find and delete the "/ oncache" folder name instead.

8.) Delete Files (if available):

0 12 * * * rm -rf directory

Above, rm is the command to delete a file that runs on linux. If the directory specified by -rf setting exists, deletion is performed. You can put the directory that will be deleted if you check the directory above and if it exists.

9.) File Creation and Authorization:

0 12 * * * mkdir -ma = rwx / home / new_directory

Above, we see a command that creates a new folder at the specified times and gives permissions to this folder CHMOD. The folder a = rwx specifies that the folder will be created in a location that is allowed to Read, Write, and Run Commands. R = Read, w = Write, x = Execute. You can change the CHMOD settings by removing the letters there.

10.) Update Awstats statistics:

0 12 * * * / user / stats /awstats.pl -config = AWStats. SiteName .com.conf -update

The above command is used to update the Awstats statistics in the specified periods. Update the locations we highlighted in bold with your own hosting and server information.

We gave many important and frequently used examples above. Apart from these, there are thousands of different codes and commands. What you do not know and wonder Hosting Directory as we will answer in the comments section below.

Frequently Asked Questions About Cron Jobs

Why Should I Use Cron Jobs? There is absolutely no obligation to do this once. It is a structure that provides great advantages to its users when used and helps to save web sites in adverse situations. Even if you do not look at your server for a long time, it creates and deletes the files that make up the server in your name. Your name tells you the status of other web sites and emails you. For this reason, we find it useful.

Does Plesk Panel Support Cron Jobs? First of all, all servers with a Linux operating system support these commands. There are different forms in Windows operating systems. If your Plesk you can enter commands on your dashboard section under the Task Scheduler is installed on Linux.

Why do not my scheduled tasks in my server and shared hosting work? Some hosting companies turn off the use of Cron Jobs during the initial opening phase. If these tasks are not working on your server or in your host package, ask your customer support staff to open them up. Firms will not respond to this, but if not, we suggest you change your host provider.

How Can I View Cron Jobs Logs? Go to your server's file management section. ETC folder or the Var / log folder. You can view the history of processes executed and executed by cron jobs in the sys or rsyslog files in these folders. These folders may differ according to the hosting companies.But the first thing you need to do is log and etc folders.

We shared a detailed and comprehensive article on the subject with you. Please use the following section for any questions, comments and suggestions.

What is MySQL? MySQL Database with Details

In today's post, we will tell you all the details about the MySql database. Shortly before we examine in detail the Database technology after writing the subtitle of this issue it was time to descend.

We will go into details about MYSQL which is the most preferred open source database used in web hosting technology. Briefly speaking, it can be thought of as a server software and web application developed for dynamic web sites that allows high-dimensional data to be stored with special technology and to be accessed at high speed when requested.

When viewed in a word sense, MySQL is an open source web software that uses SQL (Structured Query Language) SQL technology. The MY at the head can be thought of as a special name.

It is used by hosting companies at very high rates because it is developed as open source. The main reason for this is the fact that the command sets that both costs are very low are well known by the web designers and software developers on the market.

MySQL Database Capabilities

In database systems, Which is large enough not to be placed in the lines of code and has continuous variable values, is stored in the appropriate conditions and can be accessed at any time to the desired data fragment.

MySql is a software that is installed on the server at the same time. Users interact with the database in the server by sending queries with the dynamic code pages they prepare. What does Mysql do and what kind of skills do they have. Now let's look at these briefly.

a.) Easy Inquiry Infrastructure: Through our extensive command directories that it has a library which allows hundreds of different queries based on users' needs are available. One of the most important advantages is that the descriptions of the script directories it has are explained in detail on the internet and supported by many examples.

b.) Strong Character Set Support: Language of all over the world and designed in accordance with the storage of the alphabet in the transition between these alphabets MySQL also provides great convenience. For example, UTF-8 or 1259-9 character sets are used to ensure that Turkish characters are displayed on web pages while typing code pages. Here are the character sets and thousands of other supported by Mysql.

c.) The MyISAM engine technology: the search can be done in full view of the information contained in the database With this technology. In other words, it is a system specially developed for interior arming.

d.) Query Caching: During the next query is cached queries in a certain number of previously made faster and server processor sends the page using much less.

e.) phpMyAdmin interface: Web hosting companies, is the name of the front-end software will show users the software they install the MySQL database server. By accessing your database with phpMyAdmin, you can view, change, and edit basic settings.

Hosting Technology and MySQL Database

Today, many server and web hosting companies, especially those who use linux operating system, present MySQL as a database to their customers. MySQL is a must-have for commercial hosting companies, making it a no-nonsense and incredible experience for users at all levels.

Shared hosting has strengthened from interfering with each other in any way which is built on a single database server packages and individual settings and work with properties for all users on the location of the MySQL significantly. On this page, a standard dedicated server with thousands of different websites and users is provided with a single MySQL software support, all separated.

Important Web Software Compatible with MySQL

One of the most important issues for hosting companies is the convenience and wide range of products it provides to its users. So this Hosting What is this product for users in industry and refers to what?

Forums, blogs, dynamic web sites, shopping sites, inidirm coupon sites, guestbooks and social media sites used on the internet pages are the most well known interface types in this area. Perhaps the software we are creating accounts for 80% or more of the entire Internet. Here are some of the most important software for users who want to open a site in this sector and who are looking for a hosting company.

The first name that comes to mind in this regard is known as Mysql. Let's look briefly at some web software that can be installed with mysql;

  • Forum: phpBB, smf, vbulettin, Invision Power Board, mybb, drupal software can work with MySQL.
  • Blog and CMS: WordPress is the biggest blog software, such as Typo3, Jumbo, uses database technology in CMS systems.
  • Shopping Site: Essential shopping software like Oscommerce, Magento, ZendCard.
  • Social Network: social media software like phpFox, mooSocial, Media Scripts, Oxwall.
  • Discount Coupon Systems: CouponPress is one of the most important add-ons on this subject. Works perfectly with the MySQL infrastructure.
  • Gallery and Picture Systems: Systems that integrate with visual software like zenphoto, greybox, triptracker can use MySQL infrastructure.

    Some Important MySQL Commands

  • Select: Sets the main table headers to be selected from the database.

  • Update: Updates the contents of the table.

  • Delete: Deletes the selected information.

  • Insert: Provides information entry into the specified table.

  • Order: Arranges the information in the selected columns as desired.

  • Limit: Provides information of the specified size.

  • Where: It precisely targets for information. That is, it determines which cell information is to be selected.

Apart from the above commands, there are dozens of different MySQL commands. Some of these commands make processing easier, while others are used as standard processing commands. We made some commands and explained them in the shortest way so that you only have ear affection above.

Frequently Asked Questions About MySQL Database

Should I Pay a Fee for MySQL Hosting Company? Hosting companies usually do not charge extra for this. Already at a fairly low cost, they are offered free of charge to users of this software.

What is the difference between MySQL and other software that uses the SQL System? SQL system using different companies have developed different database software. These include PostgreSQL and Microsoft SQL Server. But Mysql has the greatest advantage with the size of the open source development environment and the experience of the ORACLE company behind it.

Compatible with MySQL Employee Code Systems: PHP, Perl, ASP, Java, the most widely used software in the world such as Ajax can be compatible with MySQL. Often these software have developed custom command sets for MySQL. For example, the insert_into command is used with php to add a piece of information.

What is a database?

In this article, we will inform you about the database which is one of the most frequently used platforms on the web and which is a must for the web sites to be easily manageable.

Database (Database): text-based websites that can be stored in text made addressing all types bilgin Un and desired structures can be used when bilgin Un in this address. Since the stored information is stored in the addresses you specify and in the shapes that you specify, you can display anywhere on your site the way you want.

Database Storage Method

Hosting - Database systems in server technologies come as a distinct feature. The area where normal files and codes are stored and the areas in which the information clusters or tables are stored in the database are generally in different positions. This process;

Think of it as C and D drives in your computer.

How your operating system and other files are located in different folders, databases are stored on different drives, different hard disks or even on different servers. Thanks to this method, both the information is more easily protected and the two different systems are clearly separated.

Information clusters stored in servers can be stored in billions or even TB, PB (TeraByte, PetaByte) sizes according to server capacities. Storing such large text information with normal files (word, excel, notepad) will take up incredible chaos and incredible dimensions.

Advantages of Database Technology

Speed: The information you store, very short code that is specifically addressed and specially grouped (php, asp, perl) with thousands or even millions of lines of information is your ability to loop processing. Instead of 1000 different files to be created for a 1000 page web site, only one page is created here, and the desired page can be displayed as desired.

Grouping: Database technology you can actually thought to as a system of statements. If you consider a table structure with row and column numbers, you can use row and column numbers as addresses. Below is an example table.

Let's show some operations that can be done with the table above;

The codes in the explanations below do not belong to any programming language. It is a term written for users to learn the logic of work.

1) Data Selection: This process can take through the rows and columns you want the information in the database. For example, if B2 will choose the information at;

Selection B2

The output of the code will remove the "Server" word.

2) Cluster Selection: All information on this process with a certain range of the database will be brought to us. For example, we only wanted to retrieve information in group B;

Selection B

Code output - Your response will be "Storage, Server, Server".

3) Sequential Selection: The information in the specified row or column with this transaction, from small to large - small to large, in alphabetical order, sorted and can be brought against us by the letters size. For example, if you want to select the information in section 2 in a straight-alphabetical order;

Alphabetical Order Selection 2

Code output

  • Domain

  • Sample

  • Server

  • VPS

.

4) Address Keyword Selection: This process can take with the address information in search of a word or phrase that you want in the database. For example, if you wanted to search for and print out the Server word in the database;

December Server

The code output will appear as B2.

5.) Adding, Deleting and Editing Information: If you want to add new information to your database or delete existing information or modify existing information, there are special codes to use for this. Today, there are codes that specifically deal with programming languages ​​such as php, asp, perl, java and database software. With these codes, we can perform the operations we want on the database. For example, the information on the table C3 above was intended to be deleted;

C3 Delete Selection Process

Or all information in group C wanted to be deleted;

C Delete Selection Process

What kind of action would we follow if we wanted to add new information. Here you will enter the address where the required information should be inserted and enter the information. For example, if you want to create a new row that does not exist in the table and add "Bilge" to column 1 in this row;

Create Data D1 Sage

Finally, we wanted to change an existing knowledge. For example, if we wanted to change the name "Server" at B3 to "New Server";

Edit Data Selection Process B3 New Server

The information in bold type in these examples is data base clients and the information written in clear color is the variables entered by the users. Platform commands and uses technical details are explained in the section.

Time Saving: this allows us a great advantage of the time while achieving incredible results when we use the database systems with short transactions codes on web pages that are dynamically designed. For example, while it may take hours or even days to design a 1000-page website as HTML, you can design a site with a PHP engine with the same interface in a few hours.

Backup Advantage: Normally designed sites that you back up all pages prepared to make the backup process, you will have to take a backup of the database is important in database technology. The total number of backup files will be extremely low because the database backup is usually made up of a single file.

Size and Capacity Advantage: Again, rather than static pages designed in HTML pages dynamically prepared and extremely little space in a container, according to a database server prune normal static system offers huge advantages.

Database Types

Different database types are available according to usage types and storage formats.

  • Relational Databases: The most widely used database type in the world. As we have told you so far, with these databases, which have two different interfaces as addressing and information, we can reach the desired address from the desired address and perform the desired operation. MySQL, MSSQL, Oracle, etc. all of the most used databases, such as Relational Database relational database system is used.

  • Fixed Databases: These are the solutions used to manipulate and store small-sized data. Each line contains a single information cell. Access to the lines is very fast. Information is accessed very quickly and very fast processing is done, but as we said at first, there are solutions that can be a solution for small size systems.

  • Hierarchical (Folding) Databases: In this database type, the information is stored as folder-subfolder - 2.3 .. level subfolder. That is, it is done by category - subcategory method. The biggest disadvantage of these systems is that they occupy large areas and the operating speed is slower than other methods. There are many well known types such as IMS, but I have to say that the usage areas are limited.

What are Database Management Systems?

We mentioned it briefly before. Dynamic engines such as Php, ASP, and Java used in computer programs or servers have all developed different methods and interfaces to deal with databases, ie programming languages. That is called a database management system for this interface.

A dynamic code running on the hosting database is located on the remote subnet; Delete, add, sort, edit, modify, etc. can do all the features. Of course, for this to work, there must be a connection between the database and the code directory and the necessary permissions must be provided.

What is meant here is; They use special techniques to protect the information in the databases. Of these, perhaps the most important authorization technology. While multiple people can access the same database, only one or some users, depending on their permissions, have the ability to correct, delete, or reach the full contents of the database. This process is called authorization and is one of the most powerful features of the management system. Article on this subject in Hosting Guide can be accessed using the search technology.

Frequently Asked Questions and Answers about the Database

Question: Which is the most used database? Answer: The world on the most widely used database, which is distributed free of charge and is supported by Oracle to MySQL database. At the moment there is version MySQL Cluster 7.2, which allows more than 1 billion queries in 5.6 version or minute on the market. Both versions are free and open source.

Q: What is the difference between Paid and Free Databases? A: At the height island easily compete with MySQL capacity and power as a closed toll system, which distributed database and database-free. There is no missing feature. This is the most commonly used and hosted server in the world.

Q: How to store database information? C: The information in your database is stored with sequential characters technology. Discrimination is made using regular expressions. In other words, addressing and information storage are performed according to the prefix and last characters. With sequential storage technology, transactions will be faster and require less storage space, since the data will take up less space.

Q: A sample MySQL home page How is it possible? A: The photo below looks at a sample database table structure and interface.

Q: What are the basic queries used in the MySQL System? A: We will explain the details of the script later. Briefly, basic operations such as ORDER, SELECT, DELETE, INSERT, UPDATE, DUMP, and CREATE are performed.

Q: What is the simplest meaning of a database? C: In the simplest terms, text format information content that is a separate field in the normal server can be done very easily stored and treated. It has a tabled structure.

Q: When setting up a new Site Which interfaces require Database technolo- gy? A: For a time, from blogs, shopping sites, article sites, discount sites, number of monitoring sites, all systems that require management interface as well as a 99% chance music sites use the database. We recommend that you do not use the system which does not use the database anyway. The source codes are like WordPress, Magento, Oscommerce, PhpBB, vBulletin, IPS Board, Joomla.

What is cPanel? Features and Details

Many applications have been developed by web hosting companies and 3rd party software producers so that the web hosting systems can be easily managed and operated by the end users. Undoubtedly the most popular and most used interface in the world Cpanel management of these applications.

Browser-based and control panel with graphical interface make it easy for users to do what they want to do, as well as many important features for hosting vendors. Perhaps the most prominent feature for hosting companies is the low-end pricing and annual fee policy.

cpanel

What is cpanel and what is it useful for?

We have briefly explained above. If we were going to give a little more detailed explanation; Is a special software installed on the server. This software is an icon based graphical interface designed to make it easier for some settings on the server to be changed, to get more information like statistics and any Logs.

Without cPanel or other graphical interfaces, almost none of the end users except experienced users could set up a site on hosting and manage this site. This is because all basic operations like database or optimization have to be done via ssh code lines. However, at this point, a simple interface provides a very easy to use.

In the picture below you can see the Hostgator cPanel Turkish management panel which we can designate as the biggest hosting company in the world.

The interface that appears in the picture above shows a slight difference (color and icon) compared to the hosting companies, but it is basically like this.

CPanel Usage

If you have cPanel with the control panel offered by the hosting company you have purchased, you have to login to the management panel first. There are several alternative methods to follow for this;

1) via a normal connection: The last part of the server you enter the ip number or website address in the address by the hosting company of your browser: Enter the port number 2082. Entrance will be like this.

  • I based site address: http://www.siteadresi.com:2082

  • I based site address: http://www.siteadresi.com/cpanel

  • I ip-based: http://1.2.3.4:2083

2) Port Secure (SSL): The only difference from the above process is to take all the information exchanged over an encrypted channel. The hosting package you purchase must not support this feature. You can review the hosting proposal for this topic. The action that needs to be done is to add the site address or ip address to the end: 2083 and use https instead of http.

  • I based site address: https://www.siteadresi.com:2083

  • I based site address: https://www.siteadresi.com/cpanel

  • I ip-based: https://1.2.3.4:2083

After the login process, a window with two separate windows appears. You can see this in the picture above. In the left small window area, there are news, hosting company's campaigns, general traffic details, server's hardware statistics, warnings, backup shortcuts, and recent backup information.

The area in the right-hand section, which consists of the sub-slabs, is the main area where the management process is carried out.

a.) Special section: This section is offered to you by the company under special campaigns or eligible for membership during that google, bing, yahoo there are marketing and advertising codes.

Advantages and Disadvantages of cPanel Interface

It is a control panel system which is simple to use once, especially with Turkish support. CPanel is the most preferred interface in the world. Panels like Plesk and vDeck come after him. Although vDeck te is very successful and has a control panel with differences, it has not reached a very large number of users yet.

One-click installation, icon optimization, powerful statistical platform, and server-front end. If you look at the disadvantages, some hosting companies may charge additional fees for cPanel, which may lead to price differences. We recommend that you compare prices carefully in this regard.
