How to install and configure Jenkins ?

Installation

1. Download jenkins.war

2. Move WAR to a web deployment dir of Servlet container.

3. Start the server (container).

4. Open web browser and go to URL http://myServer:8080, where myServer is the name of the system running Jenkins.

JENKINS_HOME

Jenkins needs some disk space to perform builds and keep archives.

By default, this is set to ~/.jenkins, but you can change this in one of the following ways :

• Set "JENKINS_HOME" environment variable to the new home directory before launching the servlet container.
• Set "JENKINS_HOME" system property to the servlet container.
• Set JNDI environment entry "JENKINS_HOME" to the new directory.

To change this path in between :

   1. Stop Jenkins completely

   2. Move the contents from old JENKINS_HOME to the new home

   3. Set the new JENKINS_HOME

   4. Restart Jenkins
