How to Disable SELinux -
Sometimes SELINUX isn't neccesary and adds a lot of admin overhead. Other times it's just plain annoying, like when today it didn't let apache access its config file.

To turn it off, simply edit the file /etc/selinux/config and where it says

SELINUX=enforcing

Change it to read

SELINUX=permissive

then reboot your machine. sorted.
