Re: [tlug] Arrrg! Permissions driving me nuts in PHP

[Kenneth Burling <burlingk@example.com>]

Dave,

If this script is part of a web page, ensure that your web browser has
permission to modify the directories where you are creating and
deleting things.

My server is running on Ubuntu (I know, different people have
different oppinions of that), but Ubuntu and Debian both run appache
as user www-data, with group www-data.  Whenever I install a script, I
make sure to chown -R www-data:www-data  <script-data-path>

This gives the script access to do whatever it wants to the area where
it is writing files too.

I have heard (though not actually verified) that Fedora and CentOS run
Apache as user apache.
