Your server has been hacked. Kill the perl process and fix your damn php.ini.

disable the following inside php.ini

allow_fopen_url = Off
disable_functions = exec shell_exec proc_open passthru popen system

This won't fix it for good, but you're on your way from here. Get the book "Apache Security" and read it. That'll help you get started. Google more about security.
