Getting started with CloudLinux OS


CloudLinux OS is simple to install. Here, you will learn how to convert a Plesk-based server from CentOS to CloudLinux OS. For illustration purposes, we are using CentOS 7 with Plesk 12 installed

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 website (note that CLN requires registration). If you have a paid license key, it can be found in CLN, or in your welcome email. For more information, refer to our “licensing” article.

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 an installation of additional drivers, and more.

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 our 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.

Now let’s check the Plesk panel interface. Our LVEmanager plugin has been installed during the conversion process. For more details regarding LVEmanager features and usage, please refer to this video.

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