How to open java program in other linux computer without terminal holding?

Question

I have written a java program with jar file. The java program is to update status of linux server so it need to keep running, but the linux server is in data center, so I need to remote to server to open the program. I use ssh to login linux server. Use command of "java -jar file.jar" to run the program.

However, the java program of the linux server will close if I close the terminal in my computer. Since I cannot keep opening my computer, I wanna know how to open the java programming without holding my computer terminal.

you need to use nohup to keep the program running after you log out.:

server:~name$> nohup java -jar file.jar &

this will keep your program running

Here is the response: "nohup: ignoring input and appending output to `nohup.out'" – Allen Mar 24 '14 at 09:12
thats fine, it says that any `System.out.println()` will go to file named nohup.out – Dima Mar 24 '14 at 09:27

Two ways

One

nohup java -jar file.jar &

Another

java -jar file.jar &

In both cases your process will go in background however the process will terminate in the second approach when shell terminates in second case.

That is perfectly fine your stdout will be redirected to nohup.out. Point is did your process go into background, or it did not? – Puru-- Mar 24 '14 at 17:56

If this program is intended to be running on all your machines for monitoring purposes, you should be running it as a service from your server's init system (systemd for most systems these days). You can use the Java Service Wrapper or jsvc or write your own init script.

Another solution apart from the proposed one:

screen -d -m java -jar your.jar

You will then have a detached screen with your java command in it. List with screen -l, reattach with screen -D -RR <screenid_obtained_via_screen_-ls>
