How to Install and Configure CloudLinux on cPanel

The following guide will walk you through how to install CloudLinux and configure things like the PHP Selector, MySQL Governor, CageFS, and the LVE Manager, and others.

Installing CloudLinux

Before you can install CloudLinux, you must have either a key, or an IP based license. When you purchased your license through NDC Host, you are issued an IP based license.

Log in to your server through SSH

Use the following sections to start installing CloudLinux:

For IP based license

sh cldeploy -i

Once this is complete, reboot the server to start on the new CloudLinux Kernel.

For Key based license

sh cldeploy -k <insert key here>

Once this is complete, reboot the server to start on the new CloudLinux Kernel.

Installing the LVE Manager and CageFS

Once CloudLinux has been installed, you will need to install the LVE and CageFS to be able to use the rest of the features.

Run the following commands:

yum -y install lvemanager cagefs
cagefsctl --init
cagefsctl --enable-all

Setting up LVEmanager in WHM

Once that has been installed, a new option in WHM will be under PluginsCloudlinux LVE Manager will allow you to see packages and usage settings. You can change available resources by WHM package type.

Installing MySQL Governor

If you are using MySQL, run the following:

yum remove db-governor db-governor-mysql
yum install governor-mysql 
/usr/share/lve/dbgovernor/ --install

If you are using MariaDB:

make sure to specify your MariaDB version instead of XX as follows:

MariaDB v5.5 55
MariaDB v10.0 100
MariaDB v10.1 101
yum install governor-mysql 
/usr/share/lve/dbgovernor/db-select-mysql --mysql-version=mariadbXX
/usr/share/lve/dbgovernor/ --install

Configuring MySQL Governor

To configure and use the MySQL governor, you will need to use the dbctl command in the command line. This feature does not have a cPanel or WHM interface.

Installing PHP Selector

You must have the CageFS and LVE Manager already set up before you can use this.

Run the following from the command line:

yum groupinstall alt-php
yum update cagefs lvemanager

Configuring the PHP Selector

Once the PHP selector has been installed, you can configure the base options for each version of PHP inside of WHM under the CloudLinux LVE Manager. To change versions per cPanel account, log in to cPanel and make the changes under the Select PHP Version button under Software.

Installing Python and Ruby Selector

Very similar to the PHP Selector, you can also install the Python and Ruby selectors to be able to change your versions on the fly as well as create directories for projects inside of cPanel.

Run the following commands in SSH to install the Python and Ruby selectors:

yum install lvemanager alt-python-virtualenv alt-mod-passenger
yum groupinstall alt-python
yum groupinstall alt-ruby 
yum install alt-python27-devel

Configuring the Python and Ruby Selector

Once the selectors have been installed, you can access them inside of cPanel under Software

Installing Apache mod_lsapi

Apache mod_lsapi is based on the Litespeed apache replacement. It can improve performance for many web sites.

Make sure that your server meets the requirements before attempting to use this

Installing Apache mod_lsapi

Log into SSH and run the following commands:

yum install liblsapi liblsapi-devel --enablerepo=cloudlinux-updates-testing
yum install cpanel-mod-lsapi --enablerepo=cloudlinux-updates-testing
/usr/bin/switch_mod_lsapi --setup
/usr/bin/switch_mod_lsapi --enable-global
service httpd restart

mod_lsapi does not require any additional configuration and is ready to start using immediately after installing.

Installing OptimumCache

OptimumCache is a file cache system specifically designed to help speed up shared hosting. This means that common CMS platforms like WordPress and Joomla will see a lot of benefit with this installed.

To install this run the following in SSH:

yum install optimumcache

Configuring OptimumCache

OptimumCache is very easy to configure for a basic cPanel setup. If you have your home directory somewhere else, be sure to modify the command to point OptimumCache to the right place.

Run the following command to configure OptimumCache:

occtl --recursive --mark-dir /home
