I am trying to run the command java -jar jenkins.war. It successfully runs, and I am able to access it via http://localhost:8080.

But when I type CTRL+C from the command line, the jenkins service goes down.

Can anybody tell me what the issue could be?

jenkins version : 1.654

java version:
openjdk ve**strong text**rsion "1.8.0_121"
OpenJDK Runtime Environment (build 1.8.0_121-b13)
OpenJDK 64-Bit Server VM (build 25.121-b13, mixed mode)

Can anybody tell me whether I need to run jenkins as a sudo user or if it's due to another problem?

  • You are running Jenkins as a foregroung process instead of a background process. Install jenkins as a service. Plenty of tutorials available online – ben5556 Oct 16 '18 at 18:55

You probably should install it as a service, but giving credit to this post.

Start jenkins in the background

There is the option to run it in the background.

you've installed it as a stand alone server. Leave that terminal as it is if you want to keep your jenkins running. For doing other stuff, open a separate terminal/cmd.

you can install it as a service, it runs in background and start when machine starts. you can also change the port in which it starts. default being 8080

Install Jenkins as a service

also if you have problems installing it as a service, try to start the jenkins initially from cmd opened in administrator mode, then do the above steps.
