Running in the screen is the safest and reliable way to keep running a
script after we logout. Steps are:
(i) type "screen" -- this will create a new screen and you'll be inside the
screen.
(ii) python myserver.py (while you're inside the screen)
(iii) Ctrl + A + d -- will take you out of the screen -detaches screen (but
the screen keeps running and also your script)
(iv) Now, you can logout of the server. Once you return, or anytime you need
to "view" the python process running, you need to RESUME the screen that is
detatched. You can do this by issuing : screen -ls (will list out all the
running screen's PID)
screen -x #PID of screen to resume
Note: You can do lot more than just running a single process in the screen.
"man screen" can explore those.
