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.
Prerequisites
- A server running one of the following operating systems: AlmaLinux 8.
- It’s recommended that you use a fresh OS install to prevent any potential issues.
- A
non-root sudo useror access to theroot user. We recommend acting as anon-root sudo user, however, as you can harm your system if you’re not careful when acting as the root.
Install Linux Kernel 5.15 on AlmaLinux 8
Step 1. First, let’s start by ensuring your system is up-to-date.
sudo dnf update sudo dnf install epel-release
Step 2. Installing Linux Kernel 5.15 on AlmaLinux 8.
Now we add the ELREPO repository to your system using the following command:
sudo rpm --import https://www.elrepo.org/RPM-GPG-KEY-elrepo.org sudo dnf install https://www.elrepo.org/elrepo-release-8.el8.elrepo.noarch.rpm
Then, install Kernel 5.15 with the below command:
sudo dnf --enablerepo=elrepo-kernel install kernel-ml kernel-ml-devel kernel-ml-headers
At the end of the installation, restart the system:
reboot
After logging back into your Rocky Linux 8 / AlmaLinux 8 / CentOS 8 system, run the following command to check the kernel version running:
uname -r
Output:
[root@idroot.us ~]# uname -r 5.15.1-1.el8.elrepo.x86_64
Congratulations! You have successfully installed Linux Kernel. Thanks for using this tutorial for installing Linux Kernel 5.15 on your AlmaLinux 8 system. For additional help or useful information, we recommend you check the official AlmaLinux website.
