how to change port number for Jenkins installation In Ubuntu 12.04


I am trying to install jenkins in ubuntu. I have followed the commands below:

wget -q -O - | apt-key add -

echo deb binary/ > /etc/apt/sources.list.d/jenkins.list


apt-get update


apt-get install jenkins

but It shows

  • Starting Jenkins Continuous Integration Server Jenkins The selected http port (8080) seems to be in use by another program
    Please select another port to use for jenkins

Need help on how to set a different port for Jenkins to run.


First open the /etc/default/jenkins file.
Then under JENKINS_ARGS section, you can change the port like this HTTP_PORT=9999.

Then you should restart Jenkins with sudo service jenkins restart.

Then to check the status use this command sudo systemctl status jenkins
