Jenkins cannot start - Start request repeated too quickly

DevSecOps
#1

Refering to course : DevSecOps - Kubernetes DevOps & Security

The Jenkins does not start when “systemctl start jenkins” and provide error:

Nov 17 06:48:13 devsecops-cloud systemd[1]: jenkins.service: Start request repeated too quickly.
Nov 17 06:48:13 devsecops-cloud systemd[1]: jenkins.service: Failed with result 'exit-code'.

I have modified the jenkins.service file from /usr/lib/systemd/system based on link.

I still get the same error :frowning:

Kindly help.

Thank you,

Here you want to look at the log file for jenkins, to see what’s up. Here’s what I see:

[bob@devsecops ~]$ journalctl -xeu jenkins.service
Hint: You are currently not seeing messages from other users and the system.
      Users in groups 'adm', 'systemd-journal', 'wheel' can see all messages.
      Pass -q to turn off this notice.
No journal files were opened due to insufficient permissions.

So we’re running JDK 11 and not JDK 17 or 21. Not sure why; I’ve tried to install JDK 17, and systemd simply ignores it. I’m passing this to the lab team to figure out WTF is up with this lab.
