Install Chkrootkit on AlmaLinux 9

In this tutorial, we will show you how to install Chkrootkit on AlmaLinux 9. In the ever-evolving landscape of cybersecurity, ensuring the integrity of your Linux system is paramount. Rootkits, a particularly insidious form of malware, have the potential to go unnoticed and wreak havoc on your system’s security. Enter Chkrootkit, a powerful tool designed to detect these covert threats.

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 Chkrootkit on AlmaLinux 9. You can follow the same instructions for CentOS and Rocky Linux or RHEL-based.


  • A server running one of the following operating systems: AlmaLinux 9.
  • It’s recommended that you use a fresh OS install to prevent any potential issues.
  • SSH access to the server (or just open Terminal if you’re on a desktop).
  • An active internet connection. You’ll need an internet connection to download the necessary packages and dependencies for Chkrootkit.
  • 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.
