how to change port number for Jenkins installation In Ubuntu 12.04

Question

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

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

Answer 1

1. First, run this command to open jenkins configurations:

    sudo nano /etc/default/jenkins
   

2. The only part you need to change is:

    #port for HTTP connector (default 8080; disable with -1)
    Http_port = 8080
   

   There you need to change to the desired port. For example:

    HTTP_PORT = 8081
   

3. Finally, Restart Jenkins service by running this command:

    sudo service jenkins restart
   

Then you're ready to open it with a new port.
