In this tutorial, we will show you how to install Jenkins on Debian 11. For those of you who didn’t know, Jenkins is an automation server and continuous integration tool. It provides a number of plugins for building deployments and automation for your applications. It is written in Java used by software developers to automate different aspects of building, testing, delivering, and deploying software applications.
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 through the step-by-step installation of the Jenkins on a Debian 11 (Bullseye).
