Install KernelCare on Your Linux Server

In this tutorial, we will show you how to install KernelCare on your Linux server. For those of you who didn’t know, KernelCare is a fabulous kernel update tool by CloudLinux. We started testing this kernel patch in a few servers and the result has been truly amazing, allowing us to avoid server downtime after kernel updates because of each server reboot we had to apply after the kernel was updated.

This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you the step-by-step installation KernelCare on your Linux server.


  • A server running one of the following operating systems: Linux OS.
  • It’s recommended that you use a fresh OS install to prevent any potential issues.
  • A non-root sudo user or access to the root user. We recommend acting as a non-root sudo user, however, as you can harm your system if you’re not careful when acting as the root.
