When I wanted to change the Jenkins user I first checked

/etc/init.d/jenkins script. There I found two important variables $JENKINS_CONFIG(=/etc/sysconfig/jenkins) and $JENKINS_USER. So if you want, you can change the JENKINS_USER variable in the

/etc/init.d/jenkins file; but it is not the correct way to do.

To change the jenkins user, open the

/etc/sysconfig/jenkins

(in debian this file is created in

/etc/default

) and change the JENKINS_USER to whatever you want. Make sure that user exists in the system (you can check the user in the

/etc/passwd

file ).

$JENKINS_USER="manula"

Then change the ownership of the Jenkins home, Jenkins webroot and logs.

chown -R manula:manula /var/lib/jenkins 
chown -R manula:manula /var/cache/jenkins
chown -R manula:manula /var/log/jenkins
