$_SERVER['REMOTE_ADDR'] doesn't work with php-fpm and nginx - php

Question

I don't know why with nginx this variable $_SERVER['REMOTE_ADDR'] doesn't echo an IP. On every other web server it works as it should.
Any suggestions?

Answer 1

I suspect it has something to do with the interface between nginx (the webserver) and fastcgi, which is the API in which PHP is running.
According to your info provided, the Server API is: FPM/FastCGI
I suggest you take a hard look at the details of how PHP is installed with nginx (you have not provided any).
If you do not require the performance of nginx, then you may find a pragmatic solution is to just use apache. I use nginx as a reverse proxy in front of apache, but that introduces some additional issues with getting the REMOTE_ADDR passed to PHP (notably, mod_rpaf).
Good luck!

#Michael, here is a project I maintain which provides the proper fastcgi parameters for interfacing Nginx with FPM. Hope it helps.

These are from the conf file from nginx
user http;
worker_processes 1;
error_log /var/log/nginx/error.log;
pid /var/run/nginx.pid;
events {
worker_connections 1024;
# multi_accept on;
}
http {
include mime.types;
default_type application/octet-stream;
access_log /var/log/nginx/access.log;
sendfile on;
#tcp_nopush on;
#keepalive_timeout 0;
keepalive_timeout 65;
tcp_nodelay on;
gzip on;
gzip_disable "MSIE [1-6]\.(?!.*SV1)";
server {
listen 80;
server_name www.fireangel.ro fireangel.ro;
access_log /var/log/nginx/localhost.access.log;
Default location

Parse all .php file in the /srv/http directory

Disable viewing .htaccess & .htpassword
