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

wget http://repo.cloudlinux.com/cloudlinux/sources/cln/cldeploy
sh cldeploy -i

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

For Key based license

wget http://repo.cloudlinux.com/cloudlinux/sources/cln/cldeploy
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 Plugins. Cloudlinux 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/mysqlgovernor.py --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/mysqlgovernor.py --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.
