Optimize And Improve Speed CPanel Step By Step

Let’s go through the steps of this guide to learn How to Optimize And Improve cPanel speed. There are 5 suggested steps include an explanation that helps you optimize cPanel and speed up it.

Step 1:

Install CloudLinux

Previously, you have learned how to install CloudLinux on cPanel. When you install CloudLinux on cPanle, you are improving the stability because it limits the resources. The security and efficiency will be increased, multiple PHP version and Hardened kernel are other features of this integration. In this way, you can provide an admin interface within cPanel and WHM software to manage account usage easily.

While you log in as a root user, open an SSH account and run the following commands:

sh cldeploy -k <activation_key> # if you have activation key    or
sh cldeploy -i # if you have IP based license  

Step 2:

Install LiteSpeed webserver

LiteSpeed is a proprietary web server built as a drop-in replacement for Apache. To install LiteSpeed you need to consider some prerequisites such as a LiteSpeed Web Server license. In case you do not prefer to buy a license, you can use the Free Starter plan on a server with less than 2GB of memory. Since it only works with LiteSpeed Enterprise Edition, you need to provide a trial key or an Enterprise License serial number. SSH root access to the cPanel server with root privileges is also required. In the following, you will review the steps of installing the LiteSpeed Web Server plugin for cPanel/WHM.

You are recommended to install the WHM PLUGIN LSWS through one line auto-installer. Here are the steps of installing the whm plugin, LSWS, and PHP.

1. Install LiteSpeed WHM plugin

cd /usr/src; curl | sh Uninstall WHM

Uninstall WHM

You can uninstall the WHM LiteSpeed plugin by running the following command:


2. Install LiteSpeed Speed Web Server from within WHM

To pass this step, follow the path below one by one:

1- Click the “LiteSpeed Web Server” plugin

2- Click “Install LiteSpeed Web Server”

3- Fill in the form to specify

Then, consider the following tips:

_ Trial license key or serial number

_ LiteSpeed target installation directory

_ Port Offset (set to 0 to replace Apache otherwise set a number like “2000” for example to try LiteSpeed on port 2080)

_Whether to enable PHP SuEXEC

_ Your Administrators email address.

_ Username and password for LWSW WebAdmin Console

4- Click ”Next” to install LiteSpeed

3. Config PHP

The plugin will handle EA4 through the script. The plugin of LiteSpeed will detect the right configuration and correct them when needed. So, you do not need to build matching PHP.

You should build a matching PHP binary for EA3. Although the LSWS comes with a pre-built PHP 4 binary, you must build your own PHP using configuration options matching those used by Apache mod_php. Then, click ”build Matching LSPHP” and be aware that this will take a while.

You may see one of the following error messages when running ”Build Matching LSPHP”, try increasing ”Max cPanel process memory (minimum: 512)” in the side menu under Server Configuration Tweak Setting to at least 512MB.

Found Errors
ERROR: /usr/local/bin/php -i returns 6
You can try to build matching PHP from command line:   "/usr/local/cpanel/whostmgr/cgi/lsws/"


Found Errors    ERROR: /usr/local/bin/php -i returns 134    You can try to build matching PHP from command line:   "/usr/local/cpanel/whostmgr/cgi/lsws/"

4. Start LiteSpeed again

To start LiteSpeed, click ”Restart LiteSpeed”. If you have passed the above steps carefully, all should be ok and working now. So, it is time to replace Apache with LiteSpeed Web Server. To do this, click ”Change Port Offset” and set the value to 0 if you had not done so previously. Next, click ”Switch to LiteSpeed” to finish it.

Very Important: Do not uncheck the ”Apache Web Server” service under WHM’s service manager. If you do, WHM will not restart LiteSpeed automatically when configuration changes have been made.

Step 3:

Upgrade MySQL database to MariaDB

In this step of Optimize and improve cPanel speed, you need to upgrade from MySQL to MariaDB. It would not be so challenging since MariaDB is designed to be a drop-in replacement for MySQL. In the following, you will learn how to install MariaDB over your MySQL server. You will be successful to proceed with this migration if you go through the below steps as the simplest method.

1- Update your software repositories list with the MariaDB repos

2- Update your Linux package manager with the new repos

3- Stop MySQL

4- Install MariaDB with the package manager

All the above steps should be done after you prepare the backup. You can reliably switch to MariaDB and then switch back to MySQL. Choose your distro, MariaDB version, and download mirror, then copy and run the command created by the wizard to install the repository signing key, and copy the repository configuration into your source list. Next, run your package manager’s update command, stop your MySQL server, and then install MariaDB with your package manager. Your package manager should run mysql_upgrade automatically. This is a necessary step to check all your tables for compatibility with the current version of the MariaDB and fix anything that is not right. If it does not, run mysql_upgrade manually. Then restart MariaDB, check your log files, and if no error appears, you’re done.
