How to run a program autonomously on a server, how to run java program indefinitely on server? [closed]

Question

I have a jar executable that I'm trying to run until stop on a linux server. I've tried looking at the Java Service Wrapper API, but it was really difficult and I'm not even sure that's what I want. Is there a way I can run a program on the server so that when I log off the program keeps running? I'm using ssh to login to the server and commandline to run the jar. Thanks!

Answer 1

Run:

 nohup java -jar myjar.jar &

The ampersand at the end will run it in a new forked process, so it will continue after you log out. nohup prevents it from hanging up when its owner logs out.

Answer 2

If you have the ability to set the Server as a Daemon you can do so. If not you can try to use a programm like screen to create a virtual Terminal.

sudo apt-get install screen
screen java -jar myJar.jar

if you want to reatach your terminal:

screen -r
