Getting ip address from fastcgi for Wordpress plugin

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/)

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;

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.
