If you can get apache working but dunno how to restart it, then you have some issues
/etc/rc.d/init.d/httpd restart
/etc/rc.d/init.d/apachectl restart
or
/etc/rc.d/init.d/apachectl stop
/etc/rc.d/init.d/apachectl start
or
/www/bin/apachectl stop
/www/bin/apachectl start
All found on google.com, if they don't work I dunno since I am not even close to good with apache.
Hopefully it works!
