You might also consider disabling SELinux, if the machine is behind
reasonable firewalls. SELinux has been a *disaster* in system
security, costing far more wasted productivity and engineering
resources than many of active worms or attack vectors of the Linux
world, most of which it does not really help with. (Bad PHP is bad
PHP, and SELinux does not necessarily help at all.)
