fcgi-nginx.conf

A basic FastCGI configuration for nginx looks like this:

location /yourapplication/ {
    include fastcgi_params;
    if ($uri ~ ^/yourapplication/(.*)?) {
        set $path_url $1;
    }
    fastcgi_param PATH_INFO $path_url;
    fastcgi_param SCRIPT_NAME /yourapplication;
    fastcgi_pass unix:/tmp/yourapplication-fcgi.sock;
}

This configuration binds the application to /yourapplication. 
If you want to have it in the URL root it’s a bit easier because 
you don’t have to figure out how to calculate PATH_INFO and SCRIPT_NAME:

location /yourapplication/ {
    include fastcgi_params;
    fastcgi_param PATH_INFO $fastcgi_script_name;
    fastcgi_param SCRIPT_NAME "";
    fastcgi_pass unix:/tmp/yourapplication-fcgi.sock;
}
