Install Jenkins on Debian

Installing Jenkins on Debian is a trivial task – a package is available, through aptitude, and default configuration is sufficient. This tutorial does not cover advanced security topics. By default, port 8080 is open and no authentication required – this poses a major security risk; thus if you rely solely on the instructions below, you should not expose your Jenkins server on an external network. Basic authentication instructions are provided. Root level access is required.

NOTE: This article relies heavily on instructions found here: http://pkg.jenkins-ci.org/debian/

1. Add the Jenkins repository key:

wget -q -O - http://pkg.jenkins-ci.org/debian/jenkins-ci.org.key | sudo apt-key add -

2. Append the following repository to /etc/apt/sources.list:

deb http://pkg.jenkins-ci.org/debian binary/

3. Update the package index: apt-get update 4. Install Jenkins:

apt-get install jenkins

5. Start the Jenkins service:

service jenkins start
