How can I point Jenkins to another jenkins home directory

Question

I have the working /.jenkins folder under a specific user in home on Linux. I want to start Jenkins with another user. How can I do this?

Answer 1

I think this can help you out.

Set an Environment Variable JENKINS_HOME pointing to the .jenkinsfolder and run the Jenkins command.

The shell should be like

export JENKINS_HOME=/usr/jhon/.jenkins
java -jar jenkins.war

The batch should be like  

SET JENKINS_HOME=C:\users\jhon\.jenkins
java -jar jenkins.war

Answer 2

Here are the options you have:

a) Assuming you're deploying Jenkins into Tomcat,you can do the following:

In your catalina.home/conf/localhost/jenkins.xml

<?xml version="1.0" encoding="UTF-8"?>
<Context docBase="/home/enomad/projects/jenkins/jenkins-master/war/target/jenkins" path="" reloadable="true">
 <Environment name="JENKINS_HOME" value="/home/enomad/projects/jenkins-home"
         type="java.lang.String" override="false"/>
</Context>

b) You can export the JENKINS_HOME=toWhateveryouwant as mentioned by Harsha in the previous post

c) You can extend your JAVA_OPTS params and add -DJENKINS_HOME=/path/to/jenkins_home.
