Hi There,
I know this question has probably been churned over and over in various
different variations, so i applogise in advance if its one of those
‘here we go again’ posts 
We are a hosting provider that is currently using the LAMP stack to host
our clients websites. 80% of these are on our shared hosting instance
that currently has PHP 5.3 using safemode to assist in keeping sites to
their own area. We are looking to build a new shared service and have
been playing with nginx/php-fpm (on debian squeeze) and love the easy
configuration and speed.
My question is: What is the best way to go about setting up a shared
hosting environment for 1000’s of customers, which is secure from the
point of view that the customers can’t access other sites.
Im not looking for a how-to, really just a “this is the correct way you
should look todo this” hint that will point us in the right direction.
Thank you for reading!
PS: Would like to stick with debian if thats possible
Simon
