	<h2>Make Sure that Services Autostart on Boot</h2>
	<p>On Redhat 7.3 it is not guaranteed that Apache and MySQL automatically
	restart on boot. You should run /usr/sbin/ntsysv and set the following
	daemons to be started at boot:
	<pre>
	httpd
	mysqld
	</pre>
	It is not necessary to reboot after doing this as they should already be
	running by this point in the installation.
	<pre>
	/etc/init.d/httpd restart
	/etc/init.d/mysqld restart
