cPanel

When you host on a cPanel server, you will receive a ready kernel along with the control panel. However, you can replace the hardened cPanel kernel with any standard third-party kernel.

Note: The hardened kernel from cPanel & WHM version 68 is now deprecated. This kernel no longer receives updates. As a result, we strongly advise you to enable symlink protection options after removing the hardened kernel.

We also recommend that you schedule downtime for this process because it necessitates a server reboot.

To replace cPanel’s Hardened Kernel with a Standard Kernel

We begin by removing the hardened kernel provided by cPanel, followed by kernel installation.

Log into your server with SSH
Run this command
```
rm /etc/yum.repos.d/cPkernel.repo
```
The cPkernel or cPanel kernel will be removed from the server by the system.
Now, run this command too
```
yum list --showduplicates kernel
```
You will see a list of available kernels that you can install on the system.
Run this command to install a kernel
```
yum install KERNELNAME
```
Remember to replace KERNEL NAME with the name of the kernel version you want to install.

We recommend you run:
```
1 yum install kernel-2.6.32
```
This command will install the most recent kernel version available.
Once the installation is complete, restart your server.
