For cPanel & WHM version 11.50


To install CloudLinux before you start the cPanel & WHM or cPanel DNSONLY installation process, use an ISO or download the installation script from the CloudLinux repository.


There is a known incompatibility when cPanel & WHM or cPanel DNSONLY run on CloudLinux under Centos 5.X. After you run the backup process for the first time, the backup partition will become stuck with an active lock. To resolve this issue, you must manually remount and unmount the backup partition. 


  • If you purchase an IP address-based CloudLinux license, the cPanel product installation process automatically installs CloudLinux.
  • You must obtain a CloudLinux license before you initiate the installation process. 
    • This license allows you to run CloudLinux and to receive patches and updates. 
    • You can acquire the license from your provider or from the cPanel Store. If you purchase the license from the cPanel Store, you will automatically receive an IP address-based license. 
    • This license is granted based on the static IP address at which you installed the operating system (OS).   

Install CloudLinux from an ISO

To install CloudLinux from an ISO, perform the following steps:

  1. Download the CloudLinux ISO that matches your server's architecture.
  2. Burn the ISO to CD or DVD, and install it on your server.


    After you place the OS installation disc in your server, a prompt will ask you to test the disc before you begin installation. We strongly recommend that you test the disc before you proceed. This test saves time if the disc is unreadable.

  3. From the command line, run the following commands:

    yum update
