how to check Jenkins is installed in centOS7 or not?
Is there any command for that?.
Thanks!!
Go to your /var/lib/jenkins/
there will be a file called config.xml
View that file cat config.xml
and there should be a xml entry called:
<version>YourVersionNumber</version>
Or on the Jenkins home screen when it is running click the About button and you will see the version number there.
The generic start up for Jenkins is:
java -jar jenkins.war
Which can be found here
