#93518 — bottle app "crashes"

Hi all,

Last summer I fumbled together a small appplication that calculates both LASK 
and Elo ratings for chess. I managed to "webify" it using Bottle. This works 
nicely on my laptop for testing.

However ... (you knew there would be a however right)

Once I log off (or my user session times out) my server where I've started the 
application with python3 LASKweb.py & the application dies within a  minute, 
resulting in clients getting 404 errors when accessing the page (a simple 
table that's processed by the application).

I've tried installting bottle deamon but I keep getting errors to the effect 
that it doesn't recognize bottledeamon.
Also I've tried to run as a wsgi application, but I seem to missunderstand 
what modifications I need to do the get it to run (I get server 
misconfiguration errors on the latter).

Do anyone have a pointer to an idiot proof instruction on how to deploy a 
simple bottle application to a live server.

I use bottle as it comes to provide 2 apps that face straight onto the 
web. I have to say that I have only done half the job because I never 
got as far as daemonising them. I simply run them from a "screen" 
session. This is fine as they run on my own teeny-tiny Linux VM (256MB 
ram/5GB disk with 1 Xeon core).

I simply log in and type "screen python3 myapp.py" and remember to exit 
with ctrl-A D. One of them has been up for about 3 months now without issue.

That might not explain why you are seeing problems but could give you a 
solution that works whilst you fix the underlying issue. Or not in my case!

I would suggest using supervisor.

p. m.
