OS : Centos 7
Current Jenkins version : 2.191

I want to know if I should yum update jenkins or mannually replace jenkins.war.
I have no clue how it's installed. Is there a way to find out?

You can use command like:

rpm -qa|grep -i jenkins

If as result you see nothing, Jenkins is installed by hand. If you see some line it mean Jenkins is installed via downloaded rpm or via yum. In this case it's OK to try yum update jenkins
