How to change the Home Directory of Jenkins in Linux Mint 20

To Change Home Directory on Jenkins

Introduction:

Jenkins is an open-source automation server that supports automating the components of software development associated with structure, testing, and deploying, facilitating continuous integration and continuous delivery. It also runs in servlet containers including Apache Tomcat.

Procedure:

Check the version of the Linux Mint OS

root@linuxhelp:~# lsb_release -a
No LSB modules are available.
Distributor ID:	Linuxmint
Description:	Linux Mint 20
Release:	20
Codename:	ulyana

Now go the Jenkins page and click manage Jenkins and configure system. There you can see the Home directory location.

Create the directory inside the home user directory

root@linuxhelp:~# cd /home/user/
root@linuxhelp:/home/user# mkdir jenkinsnew

Change the ownership of this directory

root@linuxhelp:/home/user# chown -R jenkins:jenkins jenkinsnew
root@linuxhelp:/home/user# ls -la

root@linuxhelp:/var/lib/jenkins# su Jenkins 
jenkins@linuxhelp:~$ cp -r * .bash_history .config .java .owner .lastStarted .groovy .cache /home/user/jenkinsnew

Now stop the Jenkins service

root@linuxhelp:/home/user/jenkinsnew# systemctl stop jenkins

Now list the newly created Jenkins directory and list the directory

root@linuxhelp:/home/user/jenkinsnew# ls -la

Now we have to change the JENKINS_HOME directory from the following file location

root@linuxhelp:/home/user/jenkinsnew# vim /etc/default/jenkins 


root@linuxhelp:/home/user/jenkinsnew# vim /etc/passwd

Finally start enable and check the status of the Jenkins service

root@linuxhelp:/home/user/jenkinsnew# systemctl start jenkins

root@linuxhelp:/home/user/jenkinsnew# systemctl enable jenkins
jenkins.service is not a native service, redirecting to systemd-sysv-install.
Executing: /lib/systemd/systemd-sysv-install enable jenkins
root@linuxhelp:/home/user/jenkinsnew# systemctl status jenkins
