Pass real client IP to web servers

March 25, 2009 07:53PM
I'm sure this has been asked before, but I can't find an answer. I'm running nginx-0.7.44 on a server, load balancing port 80 to port 8080 on 2 other servers running Apache. I am trying to figure out how to get Nginx to pass the real IP address of the browser client through to the web servers. The web servers always log the IP address of the Nginx server instead of the client.

A Google search suggested that I needed to run a Apache proxy server on each of my web servers that then pass the request on to my real web server, so the headers are rewritten. That works, but it seems I should be able to do this with Nginx and not need to run an intermediate web server just to pass the traffic to my real web servers.

Here is my nginx.conf
worker_processes 4;

events {
worker_connections 8192;

http {
include mime.types;
default_type application/octet-stream;

sendfile on;

keepalive_timeout 60;

proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;

upstream serverpool {

server {
listen 80;
server_name www.mydomain.com;
location / {
proxy_pass http://serverpool;
proxy_redirect default;

Any help or clarification on the issue would be greatly appreciated.
