Is ngx_http_realip_module required when using Nginx + PHP-FPM?

Question

Nginx

As I understand it, if you use a bunch with Apache, then this module is needed to determine the real ip of users. And if Nginx + PHP-FPM, IP addresses will be real, this module should not be used?

Answer 1

In the nginx + apache bundle, this Apache needs an additional mod_rpaf module to convert the X-REAL-IP header to REMOTE_ADDR.
In the nginx + php-fpm bundle, no additional modules for IP are needed.
ngx_http_realip_module is needed by the "second" nginx in the nginx + nginx bundle

Answer 2

If you use or plan to use CloudFlare, then this module will come in handy, because it's good to see the real IP addresses of visitors and not CloudFlare subnets.
