Answer 1

It would be nice if you provided more info about your environment but assuming it's Ubuntu Linux you can start the services in the background or as daemons.

sudo service mongodb start
nohup python yourbottlepyapp.py &

(Use nohup if you want are in a ssh session and want to prevent it from closing file descriptors)

You can also run your bottle.py app using Apache mod_wsgi. (Running under the apache service) More info here: http://bottlepy.org/docs/dev/deployment.html

Hope this helps.

Addition: (your process still runs after you exit the ssh session)

Take this example time.py

 import time
 time.sleep(3600)

Then run:

 $ python3 time.py &
 [1] 3027
 $ ps -Af | grep -v grep | grep  time.py
 ubuntu    3027  2986  0 18:50 pts/3    00:00:00 python3 time.py
 $ exit

Then ssh back to the server

 $ ps -Af | grep -v grep | grep  time.py
 ubuntu    3027     1  0 18:50 ?        00:00:00 python3 time.py

Process still running (notice with no tty)
