Hi,  
I have nginx as frontend for serving static files and a proxy to  
apache for dinamic request.  
The problem is on the $remote\_addr that arrive to apache as 127.0.0.1

In my virtualhost:

upstream my\_webcluster {  
server 127.0.0.1:8080;  
}

server {  
…  
location / {  
proxy\_pass http://my\_webcluster;  
include /etc/nginx/proxy.conf;  
}  
…  
}

in /etc/nginx/proxy.conf:

proxy\_redirect off;  
proxy\_set\_header Host $http\_host;  
proxy\_set\_header X-Real-IP $remote\_addr;  
proxy\_set\_header X-Forwarded-For  
$proxy\_add\_x\_forwarded\_for;  
client\_max\_body\_size 10m;  
client\_body\_buffer\_size 128k;  
proxy\_connect\_timeout 90;  
proxy\_send\_timeout 90;  
proxy\_read\_timeout 90;  
proxy\_buffer\_size 4k;  
proxy\_buffers 4 32k;  
proxy\_busy\_buffers\_size 64k;  
proxy\_temp\_file\_write\_size 64k;

What I’m doing wrong here?

Thanks in advance,  
Tyler

You need to install mod\_rpaf on Apache side:  
[http://stderr.net/apache/rpaf/](http://stderr.net/apache/rpaf/)

hello there, I’m having similar(more newbie) problem with simple php,  
it gives local fcgi address in return instead of user agent’s, where to  
look?  
cheers
