Install OpenLiteSpeed on Debian 10

In this tutorial, we will show you how to install OpenLiteSpeed on Debian 10. For those of you who didn’t know, OpenLiteSpeed ​​is a free, open-source, and lightweight HTTP server developed by LiteSpeed ​​Technologies. It provides a web-based user interface for managing the webserver from the browser. OpenLiteSpeed ​​is used to easily create and manage websites. It is a powerful, modular HTTP server and can handle hundreds of thousands of simultaneous connections.

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 OpenLiteSpeed web server on a Debian 10 (Buster).


  • A server running one of the following operating systems: Debian 10 (Buster).
  • 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.
