Jenkins not picking up config file changed (/etc/default/jenkins) in Ubuntu
java, jenkins, systemctl, ubuntu
Solution
Editing `/etc/default/jenkins` does not work after Jenkins version 2.332.1, which relies on systemd rather than the init system (documentation).
Instead, run:
systemctl edit jenkins
which will bring up an editor with an empty file. Create the section below with the following:
[Service]
Environment="JENKINS_PORT=8888"
Change the port as desired and save the file (in case of nano as editor with `Ctrl + X, Y`). Finally, restart Jenkins and it should pick up the new port:
sudo systemctl restart jenkins
Problem
Using: - Ubuntu 20.04.2 LTS - Java 1.8.0_322 - Jenkins 2.332.1 I've been attempting to change the HTTP port or the User in /etc/default/jenkins file. However the changes are not picked up once I do: ``` sudo service jenkins restart ``` The answer here also doesn't seem to work: Jenkins changes in /etc/default/jenkins not working ``` sudo systemctl edit jenkins ``` just opens a new file for editing
