How To Install Glances on Rocky Linux 9

In this tutorial, we will show you how to install Glances on Rocky Linux 9. For those of you who didn’t know, Glances is a cross-platform monitoring tool that aims to present a large amount of monitoring information through a curse or Web-based interface. 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 the step-by-step installation of the Glances monitoring tool on Rocky Linux. 9.

Prerequisites

• A server running one of the following operating systems: Rocky Linux 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).
• 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.

sudo firewall-cmd --reload
