For continued compatibility with the latest versions of cPanel & WHM, please update your server to CentOS 6 or RHEL 6.
CentOS and Red Hat discontinued support for version 4 of their respective operating systems on February 29, 2012.
cPanel & WHM version 11.32 will be the last to support version 4 of these operating systems. In accordance with our end of life policy, cPanel & WHM will continue to function on these systems after the operating system end of life date.
If you currently run version 4 of CentOS or RHEL, we recommend upgrading your server to version 6 of your operating system.
To determine your installed operating system version, use the following command:
cat /etc/redhat-release
