For cPanel & WHM 11.46


If you wish to install CloudLinux before you are ready to start the cPanel & WHM or cPanel DNSONLY process, you can use an ISO or you can 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 will need to manually remount and unmount the backup partition. 


  • If you purchase an IP address-based CloudLinux license, cPanel's installation process will automatically install 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 get 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 have installed the operating system.   


Install CloudLinux from an ISO

To install CloudLinux from an ISO:

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


    After you place the operating system (OS) installation discs in your server, you will receive a prompt to test the discs before you begin installation. We strongly recommend that you test the discs before you proceed. This test will save you time if the discs are unreadable.

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

    yum update
