In this tutorial, we will show you how to install Mattermost on Ubuntu 18.04 LTS. For those of you who didn’t know, Mattermost is an open-source, private cloud Slack alternative. A workplace messaging system for web, PCs, and phones, released under the MIT license.

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 Mattermost on a Ubuntu 18.04 LTS (Bionic Beaver) server.


  • A server running one of the following operating systems: Ubuntu 18.04.
  • 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.
