I Can't start Jenkins in background (Address already in use)

I am running jenkins using 

java -jar jenkins.war -httpPort=31114

and it starts correctly, Now I am trying to run it in background, I found it can be done using nohup java -jar jenkins.war -httpPort=31114 & as mentioned here Start Jenkins in the background.

But when I terminate the session I started at the beginning and try to run it in background on the same port, I get the following error:

Solution

  • I tried adding the command nohup java -jar jenkins.war --httpPort=31114 & to a bash file and run the file, it worked
