Keep SSH Sessions running after disconnection.

I have a process which is basically a web-server, I start it during an SSH session. However, when I leave the session (by closing the PuTTY windows), it stops running and responding to requests. This is true even if I end the command with a &. With Apache, I don't have this problem, it comes with a stop, a start, and a restart script. I'd like to create something like that for this program.

How can I start a process, so that it will continue running even after I end the SSH session I started it in? Also how can I set it to restart itself if it stops for some reason?



Start it in a screen session.


Now start the process:


Then, detach the screen session with Ctrl+a d.

You can reattach to the screen session again by typing:

screen -r

If you have more sessions running you can list them with:

screen -ls

You can make it a daemon (fork it twice or have it started by the system's init daemon) or for temporary stuff use screen.
