I am running a Redhat EL5 server using Nginx 0.8.54 on the frontend,  
with Apache 2.2.3 on the backend and mod\_rpaf to forward the IP address  
to be used in filtering spam from Wordpress comments using the Spam Free  
Wordpress plugin. ([http://www.toddlahman.com/spam-free-wordpress/](http://www.toddlahman.com/spam-free-wordpress/))

I would like to use fastcgi to serve PHP, but I am not aware of any way  
for fastcgi to forward the visitor’s IP address like mod\_rpaf does for  
Apache for use by my Wordpress plugin.

I don’t currently use mod\_fastcgi to connect to an external fastcgi  
process like spawn-fcgi because I can’t get it to work, or php-fpm  
because I cannot find the proper php-common rpm and other dependency rpm  
files I need to connect memcached and other stuff.

Does anyone have a solution to this? If so could you share your complete  
configuration files from Nginx, and Apache, or the fastcgi configuration  
outside either of these applications? I am open to any and all  
suggestions, but appreciate complete config examples to save time.

Thank you.

In fastcgi visitor’s ip address is always passed to application  
with appropriate fastcgi params. Bundled fastcgi\_params file have  
them properly set:

fastcgi\_param REMOTE\_ADDR $remote\_addr;  
fastcgi\_param REMOTE\_PORT $remote\_port;

</div>

With my current configuration below the IP address is not appearing  
properly in Wordpress.

In the fastcgi.conf I have:

fastcgi\_param REMOTE\_ADDR $remote\_addr;

In the nginx.conf I have:

upstream php {  
server 127.0.0.1:9000;  
}

location ~ .php$ {  
fastcgi\_split\_path\_info ^(.+.php)(/.+)$;  
include fastcgi.conf;  
fastcgi\_intercept\_errors off;  
fastcgi\_pass php;  
}

cgi.fix\_pathinfo = 0; in php.ini

With this I got a blank page when submitting a comment.

I tried adding

```
    fastcgi_pass_header Host;
    fastcgi_pass_header X-Real-IP;
    fastcgi_pass_header X-Forwarded-For;

```

Now I get 502 Bad Gateway (Nginx).

What am I missing?

Was able to get php-fpm installed on the server from the remi repo.  
Everything works fine now with the same configuration above.

I failed to see the php-cgi process wasn’t running when I sent the last  
message. I am still getting a blank page, not 502 bad gateway.
