For cPanel & WHM 11.46


To install CentOS, you must download and burn a CentOS ISO to CD or DVD.


If you choose to download CentOS from another site, and you plan to use cPanel DNSONLY on your server, do not install the CentOS ISO that is labeled minimal. If you download this ISO, the cPanel DNSONLY installation will fail. Instead, install the generic or netinstall CentOS ISO, and then choose the minimal version during the installation process.  

Install CentOS

To install CentOS, perform the following steps:

  1. Download CentOS.
  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.
