Steps for Switching the Hardened Kernel of cPanel with a Standard Kernel

In this article, we will guide you on switching the Hardened Kernel of cPanel with a Standard Kernel. While a preconfigured kernel is provided with the control panel, you have the flexibility to replace the hardened cPanel kernel with a third-party kernel of your choice.

It is recommended to enable the symlink protection option when removing the hardened kernel. Please plan for downtime during this process as it requires a server reboot.

Follow the steps:

1. Log in to SSH and run the following command to remove the cPkernel or cPanel kernel from the server:

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

2. Enter the following command to view the list of available kernels for installation:

yum list –showduplicates kernel

3. To install a kernel, execute the following command:

yum install KERNELNAME

Note: Replace the kernel name with the version you wish to install. 

4. Installing the most recent kernel version using the following command is suggested:

yum install kernel-2.6.32

5. Start your server again when the installation is complete.
