In this tutorial, we will show you how to install Composer on CentOS 8. For those of you who didn’t know, Composer is an incredible dependency manager tool used to install and upgrade libraries for dynamic, PHP applications and projects. This software is used to facilitate the installation and update of the project dependencies which also show the appropriate versions required for the project requirements.

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 Composer on CentOS 8.
