Как использовать php-fpm в режиме tcp на внешнем компьютере?

Я использую php-fpm поверх TCP, потому что я намерен сбалансировать его нагрузку.

Должен ли я иметь файлы PHP на каждом сервере?

Или могу Я храню его на веб-сервере (Lighttpd)? Я получаю 404 Ошибка при попытке запросить простой файл php. Этот файл хранится на сервере lighttpd, а php-fpm работает на другом компьютере.

Это моя конфигурация на lighttpd:

server.modules += ( "mod_fastcgi" )
fastcgi.debug = 1


fastcgi.server += ( ".php" =>
        ((
                "host" => "10.5.0.3",
                "port" => "9000",
                "broken-scriptfilename" => "enable"
        ))
)

И конфигурация пула php-fpm:

[www]
listen = 127.0.0.1:9000
user = www-data
group = www-data
pm = ondemand
pm.max_children = 5
pm.start_servers = 2
pm.process_idle_timeout = 10s;
pm.max_requests = 500
