How to run a Python Script all day on a webserver

I wrote a twitter scraper that I want to run indefinitely on my server in开发者_运维技巧 Python/Django. How can I make sure it always runs? I understand I can make a cronjob to start it up.

However, sometimes the script errors because twitter's connection fails. How can I make something that checks if this script is still running every minute or so?

I could make a cronjob that start again every minute, but I wouldn't want that as if it is still running properly it doesn't need to be restarted.

Just ignore the exception, and start the script again.

while True:
    try:
        do_work()
    except Exception, e:
        print "Exception occurred, restarting.", e
        pass

I use this code:

#!/bin/sh
while true; do
    /path/to/my/script;
done

Add your script to the crond Job .
