Has anyone set up any form of apache user isolation on CentOS? I have multiple virtual hosts on my machine, run by users who do not trust eachother. The problem is that any php script run by apache is able to do things like raw file io on other users' .htpasswds, php scripts, hidden directory listings, and so on. Database passwords can even be divulged in this way, since they are often stored in .php scripts, which can be read "in the raw" as files by other php scripts. What is the easiest method for dealing with this? I found http://webauth.stanford.edu/manual/mod/perchild.html but it does not seem to be compiled with the CentOS 5 apache, and I've read elsewhere that php has issues with mutlithreaded apache. Is there any easy way to isolate individual users, by either having apache setuid, or chrooting php scripts, or (ugh) a clean way to run a new apache copy for each vhost?
There are a few links here discussing these issues. I have read them, but not implemented them.
