Hey, thanks for the tip with supervisord.
I found a site (http://sachachua.com/blog/2010/06/using-supervisord-for-nginxfastcgiphp/) saying its easy to set up with:
>apt-get install python-setuptools
>easy_install supervisor
And actually it was. No error on that. But then the site says I should add something to /etc/supervisord.conf, but there is no file like that? I created it with the content I got told to, but well, nothing happens now... Or is everything fine now? Is everything automated about supervisord?
