Installing Jenkins on Debian 8

You may have heard or read articles regarding continuous integration and delivery and thought how exactly does one do that? Well, the simple answer is to constantly build your application when you add new code to the code base. This can become a tiresome task as builds may take time and if a code push breaks the application you may need to roll back the push entirely. This is where a platform such as Jenkins comes in. Jenkins is software that allows for continuous integration, which means that when a developer makes changes to the code base and pushes them, Jenkins will trigger a build of the application and run any test automatically. In this article, we will cover how to install Jenkins on your server. 

 

Prerequisites:

  •  Debian server  

 

Update Debian

Let’s start with making sure Debian is up to date.

sudo apt-get update

 

Install Java

sudo apt install default-jre

 

Next, get the Jenkins source lists. 

wget -q -O - https://pkg.jenkins.io/debian/jenkins.io.key | sudo apt-key add -
sudo sh -c 'echo deb http://pkg.jenkins.io/debian-stable binary/ > /etc/apt/sources.list.d/jenkins.list'

 

Install Jenkins

Update Debian again and install Jenkins.

sudo apt update
sudo apt install jenkins

 

Start Jenkins

Restart Jenkins. 

sudo service jenkins restart

When Jenkins is up and running you can see the GUI interface by going to http://localhost:8080.
