How To Install Glances on AlmaLinux 8

Install Glances on AlmaLinux 8

In this tutorial, we will show you how to install Glances on AlmaLinux 8. For those of you who didn’t know, Glances is a cross-platform curses-based system monitoring tool written in Python. Glances provide information regarding memory, CPU, Disk IO, file system, Uptime, processes, interfaces, alerts & many other system information.

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 through the step-by-step installation of Glances real-time Linux server monitoring on an AlmaLinux 8. You can follow the same instructions for Fedora, RHEL, CentOS, and Rocky Linux distributions.

Prerequisites

  • A server running one of the following operating systems: AlmaLinux 8, Fedora, RHEL, CentOS, or Rocky Linux 8.
  • 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).
  • A non-root sudo useror access to the root user. We recommend acting as a non-root sudo user, however, you can harm your system if you’re not careful when acting as the root.
