In this tutorial, we will show you how to install htop on CentOS 8. For those of you who didn’t know, Htop is an interactive and real-time system-monitor process-viewer written for Linux. It is designed to replace the Unix program top. It shows a frequently updated list of the processes running on a computer, normally ordered by the amount of CPU usage. Unlike top, htop provides a full list of processes running, instead of the top resource-consuming processes. Htop uses color and gives visual information about processor, swap, and memory status. It is a must-have when you want to monitor the resources of your Linux server over an ssh connection for example.

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 htop system monitor on a CentOS 8 server.
