Install Jenkins on Debian 12

In this tutorial, we will show you how to install Jenkins on Debian 12. For those of you who didn’t know, Jenkins is an open-source automation server, that plays a pivotal role in automating the CI/CD pipeline, enabling developers to focus on innovation rather than repetitive tasks.

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 step-by-step install the Jenkins on a Debian 12 (Bookworm).


  • A server running one of the following operating systems: Debian 12 (Bookworm).
  • 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).
  • An active internet connection. You’ll need an internet connection to download the necessary packages and dependencies for Jenkins.
  • 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.
