File Permissions created by Apache

OS: CentOs

Whenever apache (apache2) creates a file or directory it automatically sets the permissions to 777. I want it's directories to be 775 and files 664. How can I fix this?

Put umask 002 in the end of /etc/sysconfig/httpd and restart httpd (service restart httpd) and it should do the trick for future files. Apache inherits the umask from its parent process, so this setup makes that happen.

Set the umask for apache (or whatever user it runs under):

umask 002 will provide you with 775 and 664 on new folders and files.

Check /etc/bashrc. It should already (at least on a CentOS machine) have the following stanzas:

# /etc/bashrc
# System wide functions and aliases
# Environment stuff goes in /etc/profile

# By default, we want this to get set.
# Even for non-interactive, non-login shells.
if [ $UID -gt 99 ] && [ "`id -gn`" = "`id -un`" ]; then
        umask 002
else
        umask 022
fi

This should already be getting you the behavior you want, unless you installed a custom apache, and created the apache user yourself. Even then, it shouldn't be getting 000 as the umask unless that's already explicitly set up somewhere. I mention this only because your system is exhibiting signs of a non-standard config, and because of that, it's possible that other users (system or otherwise) are also getting this far too broad file creation mask.
