Install PHP Composer on Debian 8 Jessie

In this tutorial, we will show you how to install and configure PHP Composer on Debian 8 Jessie. 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 the step-by-step installation of PHP Composer on a Debian 8 (Jessie) server.

Prerequisites

  • A server running one of the following operating systems: Debian 8 (Jessie).
  • 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.
