To Replace the Hardened Kernel of cPanel with a Standard Kernel

We start by removing the cPanel-provided hardened kernel followed by the kernel installation.

1. Log in to your server with SSH.

2. Run this command:

rm /etc/yum.repos.d/cPkernel.repo

The system will remove the cPkernel or cPanel kernel from the server.

3. Enter and run this command immediately:

yum list --showduplicates kernel

A list of available kernels will appear that you can install on the system.

4. To install a kernel, please run the command:

yum install KERNELNAME 

Do not forget to replace the KERNELNAME with the kernel version you want to install.

We recommend you run:

yum install kernel-2.6.32 

This command will install the latest kernel version currently available.

5. Reboot your server once the installation is complete.
