Install Linux Kernel 5.15 on AlmaLinux 8

In this tutorial, we will show you how to install Linux Kernel 5.15 on AlmaLinux 8. For those of you who didn’t know, A kernel is the lowest level of easily replaceable software that interfaces with the hardware in your computer. It is responsible for interfacing all of your applications that are running in “user mode” down to the physical hardware, and allowing processes, known as servers, to get information from each other using inter-process communication (IPC). Linux kernel 5.15 was released on October 31st, 2021, and it brings some interesting new features, such as a new NTFS file system implementation that doesn’t require you to rely on third-party software.

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 of the Linux Kernel 5.15 on AlmaLinux 8. You can follow the same instructions for Rocky Linux.
