This section allows us to assign the packages we previously created to our accounts. We select our account to be included in the package and click Modify. On the screen that appears, packages will be displayed. When we select the package we created and click Upgrade, we will have included our account in the package.

Cphulk blocks IP addresses making brute force attacks on your server within the periods you specify. It comes installed with cPanel. You should select CpHulk Brute Force Protection from the left menu and press the Enable button. In the Configuration section, you can change options such as how many minutes to keep a blocked IP blocked, how many invalid login attempts can come from an IP, and whether to send notification to the server administrator.

You can view access attempts from the Login/Brute History Report section. You can define your allowed or directly blocked IP addresses in the White/Black List Management section.

This is the section where we configure detailed mail settings of our server. The most commonly used features will be detailed.

Domains and IPs

If you want each site on your server to send mail over the IP address it runs on, you can do this with the “Reference /etc/mailips for outgoing SMTP connections” setting in Exim Configuration Manager. Setting this to “On” means every site on the server sends mail over whichever IP address it is running on. This is a useful method if sites on the server are distributed to different IP addresses at certain rates. If you want all sites on the server to send mail only with the IP address you specify, set this to “Off”.

Note: In some cases, settings are not automatically entered in /etc/mailips and we need to perform manual operations.

This is the section where we determine which services will run and which will be shown in the service status section. There are 2 checkboxes next to services. When we click the enable checkbox, the service becomes active; if left empty, that service will not run. If we click the second monitor checkbox, that service will be displayed in the service status section. At the same time, the service is monitored by cPanel; if the service stops, it is automatically restarted.

“Hostname” means the name representing your server.

As shown in the image, you can write the name that will represent your server in the relevant field and click “Change” to modify it.

This is the section where fine-tuning of your server is done. It consists of many sections. Explained according to the most frequent usage level.

All

Number of accounts per page to display in “List Accounts”: Asks how many accounts you want to display on the List Accounts page. Default is 30, you can write any value you want.

Domain

Allow Creation of Parked/Addon Domains that are not registered: Asks whether unregistered domains can be parked or added as addon domains. Should be in the closed state.

Allow Remote Domains

Allow Creation of Parked/Addon Domains that resolve to other servers — should remain Off as it may cause security vulnerabilities.

Mail

Max hourly emails per domain: Specifies how many emails can be sent per hour for a cPanel account. Generally this value is defined as 100.

Prevent “nobody” from sending mail: Blocks emails with an unidentified sender address. Must definitely be marked as On for blocking spam emails.

Restrict outgoing SMTP to root, exim, and mailman: Blocks mail outputs of accounts that send mail without SMTP authentication. Should be On, but may also block PHPMailer usage. Therefore, it is Off on hosting servers.

PHP

cPanel PHP max execution time: Limits how long your query will take; 900 is recommended.

cPanel PHP max POST: Limit of posted data. Default is 55M; 256M is recommended.

cPanel PHP max upload: Limit of files uploaded through browser. Default is 50M, but this limit is insufficient for SQL import through phpMyAdmin; 256M is recommended.

cPanel PHP loader: Can be selected according to the requirements of Plugins to be installed in cPanel/WHM. Generally ioncube is selected and activated.

Redirection

Redirect settings when logging in to WHM, cPanel, or Webmail interfaces.

Always redirect to SSL: If set to On, always redirects to SSL address.

Non-SSL redirect destination: Whether redirection will be to hostname or no redirection.

SSL redirect destination: How redirection should occur if https:// is used.

Require SSL: Ensures only https:// access.

Stats Programs

The section in the cPanel system where statistics software for sites is selected. Keeping Awstats stat and Webalizer stat On is recommended; Analog stat should be Off as it causes high resource usage on the server.

Stats and Logs

Extra CPUs for server load: Allows some services to be stopped according to server load status. Raising this value is recommended based on the number and power of CPUs on the server. For example, if the server load is high during cPanel automatic backup, the backup process stops and account backups are not taken. If it is important that the automatic cPanel backup is taken without interruption, setting this value to 40 is recommended.

This is the section where server time zone configuration is found. If your server time zone is wrong, errors may occur in your scripts. Therefore, it is a section that needs to be checked.

Cloudlinux is a paid kernel software especially for web hosting providers that ensures each user on shared servers is assigned a specific CPU and RAM limit and prevents exceeding these limits.

What can you do with Cloudlinux?

• If a server is consuming too much CPU, you can arrange the limits as desired with lve-manager.


• With CageFS, you can put users in a cage. This way, each user has their own space and cannot switch between other accounts.


• With MySQL Governor, you can limit MySQL resource usage.


• With PHP Selector, you can allow each user to choose their desired PHP version.


• With Inode Limits, you can define a disk inode limit for each user.


• With Mod-lsapi, you can gain performance with the LiteSpeed software.


• With OptimumCache, you can create a cache feature.

In the “ID” section, we can view the users on the server. In the other section, we can view real-time RAM usage, CPU usage, and disk write speeds of our users.

If we want to change the limits we have given to a user, we go to “Settings” from the top, select our user, and click “Edit” to change the values. This way, we can give different limits to a single user or create a package and put many users in the same package to use specific limits.

The “Select PHP Version” feature in cPanel comes with Cloudlinux. We can set the PHP version and PHP extensions at the package level from the live manager “Selector” section. This way, we set which PHP versions and which extensions our users can use.

WHM (Web Host Manager) is a web user interface software that helps end users control hosting and server services in a broader and more comprehensive way. Just as we perform many operations such as SQL installation and adding additional subdomains through cPanel when we own a hosting package, we need WHM panel for opening a hosting package and managing it at a high level.

Services like Reseller and VPS used by many internet users are offered together with WHM service. With this service, users can easily create new hosting packages using cPanel or perform some high-level changes related to their account.

Basic cPanel & WHM Setup

This is the section where contact information is edited, simple settings are made, and nameserver settings are configured. It consists of three sections: All, Contact Information, and Basic Config.

All

Tab containing contact information and basic settings.

Contact Information

Tab containing the contact information required for the server. There is a phone number and email address field to contact the server when there is a problem.

Basic Config

All information related to basic configuration is here. You can determine which IP address accounts opened on the server will use and set the server’s main IP address. The directory that determines where the hosts you create will be placed is determined by the directory you specify here. Web sites are generally hosted from the /home directory. The default cPanel theme to be used in the hosts you will create can be set here. You can also set the default Webmail theme, minimum user ID size for new accounts, and how Apache logs should be stored.

It is important to write an active and regularly monitored email address. When your server’s disk space is full, some services stop, or problems occur, critical operations for your server such as database problems on your websites are notified by email. This way, you can prevent larger problems from occurring on your server.

Name Server

This section allows you to specify nameservers that establish the relationship between your domain names/domain names and the server. When you install WHM/cPanel on a virtual or physical server, this is one of the first places you need to configure. All domains you create on the server will open with the NS addresses you configured here. The domain name you choose is very important — if your domain name expires, all sites on your server will give DNS errors and stop working because they are linked to that domain name.

For example, to configure ns1.ozgurciftci.com pointing to 95.173.189.2 and ns2.ozgurciftci.com pointing to 95.173.190.2, you need to create a special name server record with your IP addresses at the company where you registered the ozgurciftci.com domain name. Then you can enter the name server fields from your WHM panel and direct the sites on the server to these name server addresses.
