Issue
I've been following those instructions in order to install Jenkins over CentOS 7 https://www.jenkins.io/doc/book/installing/linux/#red-hat-centos
$ sudo systemctl start jenkins
jenkins.service not found
But nos service seems to be installed, no WAR is found anywhere. I don't get it. Does anybody have an idea of what I could have forgotten?
Solution
Ok, so Jenkins wasn't installed indeed, due to GPG signature check. I just didn't dig Yum's response... Shame on me.
So I changed the install command accordingly:
yum --nogpgcheck install jenkins
