I am doing the Jenkins Level 1 task in which the Jenkins installation is needed. So, I have installed the Jenkins but I am unable to start the Jenkins. I have gave
sudo systemctl start jenkins
command but getting following error
thor@jumphost ~$ sudo systemctl start jenkins
Job for jenkins.service failed because the control process exited with error code.
See "systemctl status jenkins.service" and "journalctl -xeu jenkins.service" for details.
thor@jumphost ~$
So, I have checked that port 8080 is occupied by another process. So, I tried to change the port numbrer of that process which is running on port 8080. But nothing has happened please help me.
