service php54w restart on centos 6.5

Question

I upgraded the php version to 5.4 following this guide but it seems I cant restart the service i tried

sudo service php restart
sudo service php54 restart
sudo service php54w restart
sudo service php-fpm restart (this worked on my 5.3.3 php version earlier)
sudo service php5-fpm restart

Anyone can help with the right command. I searched for it but found nothing unfortunately.

Thanks.
