Posted on March 4th, 2017

In this tutorial, we can check how to install CloudLinux OS on CentOS Server with cPanel.


CloudLinux was released to the market in 2010. Today, it is a must-have for any web host who cares about stability, security, and churn. It is used by more than 2,000 hosting companies on 20,000+ servers. It was specifically optimized for shared hosting as it isolates each customer into a separate “Lightweight Virtualized Environment” (LVE).  Web hosts that use CloudLinux report higher uptime, significant improvements in density, decrease in number of reboots, and decrease in number of account suspension they have to perform. It has also produced a significant decrease in churn for a number of customers. The software is specially designed and built for cPanel servers.


Converting to CloudLinux

It is easy to switch server from CentOS 5.x, 6.x or 7.x to CloudLinux as it is interchangeable with CentOS. The CloudLinux OS installation process takes a few minutes and replaces a handful of RPMs. Before the conversion of your CentOS server to CloudLinux, you must have an activation key. The activation key can be either obtained by trial subscription or by purchasing subscription. Follow the steps below to receive a trial activation key.

1) Go to and register with CloudLinux  Network.

2) Download the CloudLinux installation script: cldeploy. Enter the following command on your server shell or terminal.

$ wget

3) Execute the downloaded script by running the following command. The script will install CloudLinux kernel, Apache module, PAM module, command line tools as well as LVE Manager.
