Getting started with CloudLinux OS Converting Centos to CloudLinux

Getting started with CloudLinux OS. As you probably know, CloudLinux OS improves server stability, density, and security of your servers by partitioning and limiting resources, such as memory, CPU, connections, for each tenant. If you are new to CloudLinux OS, start with the basics on requirements, licensing, and how to install CloudLinux OS

CloudLinux OS is simple to install. Here, you will learn how to convert a cPanel-based server from CentOS to CloudLinux OS.

First, you will need a software activation key or an IP-based license. The 30-day trial key can be obtained for free by requesting it from the CLN portal via our Cloud Linux website (note that CLN requires registration). If you have a paid license key, it can be found in CLN, or in your welcome email. 

To install, open an SSH connection to your server using your preferred SSH console application.

Here is the syntax we are using to execute the conversion process:

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


CloudLinux OS install script is smart - it detects the environment, type of virtualization, control panel, specific hardware which might require additional drivers installation and more.

If EasyApache version 4 is in use, the script will install all the required RPM packages automatically, including the mod_hostinglimits package for the proper LVE operation.

Once the installation is completed, the server needs to be rebooted. It is required in order to boot the server with our kernel, which is specifically crafted for the LVE support and limits operation.

To make sure that the server is running the correct kernel, we can access the server via SSH again and execute the “uname -a” command.

CloudLinux kernel contains “lve” in its name - when you see it, you’ll know that the server is running using the correct kernel.

Then, you will need to check the WHM interface. As you will see, LVE Manager plugin has been installed during the conversion process. For more details regarding LVE Manager features and usage, please refer to this video.

You are all set - the CentOS server with cPanel has been successfully converted to CloudLinux OS.
