Debian/Ubuntu

On Debian-based distributions, such as Ubuntu, you can install Jenkins through apt.

Recent versions are available in an apt repository. Older but stable LTS versions are in this apt repository.

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'
sudo apt-get update
sudo apt-get install jenkins

This package installation will:

• Setup Jenkins as a daemon launched on start. See /etc/init.d/jenkins for more details.

• Create a ‘jenkins’ user to run this service.

• Direct console log output to the file /var/log/jenkins/jenkins.log. Check this file if you are troubleshooting Jenkins.

• Populate /etc/default/jenkins with configuration parameters for the launch, e.g JENKINS_HOME

• Set Jenkins to listen on port 8080. Access this port with your browser to start configuration.

If your /etc/init.d/jenkins file fails to start Jenkins, edit the /etc/default/jenkins to replace the line ----HTTP_PORT=8080---- with ----HTTP_PORT=8081---- Here, “8081” was chosen but you can put another port available.
