How To Install Composer on CentOS Stream 9

Install Composer on CentOS Stream 9

In this tutorial, we will show you how to install Composer on CentOS Stream 9. For those of you who didn’t know, Composer is a dependency manager for the programming language, PHP. It functions as some sort of project manager that helps the programmer manage dependencies that will be used on a project-to-project basis. Composer supports all the latest PHP platforms and frameworks like Magento, Laravel, etc.

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 Composer on a CentOS Stream 9.


  • A server running one of the following operating systems: CentOS 9 Stream.
  • 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, as you can harm your system if you’re not careful when acting as the root.
