Jenkins Starting issue.


Issue with starting
===================
Note: if you get the following error message, ensure that Java has been installed:
Starting jenkins (via systemctl):  Job for jenkins.service failed. See 'systemctl status jenkins.service' and 'journalctl -xn' for details                                            [FAILED]


Check for the tmp directory and if the noexec is enabled on the /tmp, try disabling it.

mount -o remount,exec /tmp

Other way around is by selecting another tmp directory

Edit /etc/sysconfig/jenkins
JENKINS_JAVA_OPTIONS="-Djava.awt.headless=true -Djava.io.tmpdir=$JENKINS_HOME/tmp"

We can get the Jenkins from URL
http://xxx.xxx.xxx.xxx:8080/jenkins/
