How To Install Composer on Ubuntu 22.04 LTS

In this tutorial, we will show you how to install Composer on Ubuntu 22.04 LTS. For those of you who didn’t know, Composer is an application-oriented package manager for PHP distributed under an open-source MIT license. 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 is also commonly used to bootstrap new projects based on popular PHP frameworks, such as Symfony and Laravel.

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 Composer on Ubuntu 22.04 (Jammy Jellyfish). You can follow the same instructions for Ubuntu 22.04 and any other Debian-based distribution like Linux Mint, Elementary OS, Pop!_OS, and more as well.

Prerequisites

• A server running one of the following operating systems: Ubuntu 22.04, 20.04, and any other Debian-based distribution like Linux Mint.
• 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.
