I’m finally getting back to Jenkins, which I started waaaay back in November (here and here). Unfortunately, I kind of forgot my password. Well, that’s embarrassing! I also want to redo the manifest using maestrodev/rvm which means starting over, so I need to back things up. The manual for Jenkins and the results on Google can be overwhelming sometimes, so I thought I’d share what I learned to hopefully save someone else.
Password Recovery
There’s a few ways I found to recover your password. One suggestion is to disable all security, delete your user, re-enable security and allow signups, and then recreate the same user and things should just “work”. Part of the reason you have to do this is that once you disable security, you can’t change the password for your user; only the user can. That’s … frustrating.
Disable security by editing $JENKINS_HOME/config.xml, /var/lib/jenkins/config.xml on my instance. I was able to get away with disabling it by changing <useSecurity>true</useSecurity> to false, though the article suggests removing two other lines. Restart the service with systemctl restart jenkins or equivalent and now you’re able to get in and recreate some users.
