Nginx as proxy and Apache with Load balancing

Hello!

I’ve three doplets, one as a Load Balancer and the other two as webservers. Load Balancer is working fine, and the webservers too at the first time.

But when I’ve added Apache to use Nginx as a reverse proxy, to get the most of the webservers, LB with webservers still is working but when I go to:

http://LoadbalancerIP/test.php

I can see that Apache isn’t working with PHP.

I’ve configured reading this:

http://www.nginxtips.com/how-to-configure-nginx-as-a-reverse-proxy-for-apache/#comment-31113

and other guides from you, but still isn’t working. I can guess that the problem is in rpaf.conf, in which I put the IP from Load Balancer.

RPAFproxy_ips LoadBalancerIP

But still isn’t working, can you help me?

Thanks in advance!
