[Web] nginx proxy mode, obtain the real IP address of the client

[Copy link]
Posted on 11/3/2014 9:48:11 AM | | |
Recently, I was recommended by a blogger, and I found a small problem, so I used $_SERVER['REMOTE_ADDR']; I got the server address 192.168.96.52, searched it, found the problem, and changed it to $_SERVER['HTTP_X_REAL_IP']; ：
nginx proxy mode, obtain the real IP address of the client
Set in nginx:

proxy_set_header        Host            $host;
proxy_set_header        X-Real-IP       $remote_addr;
proxy_set_header        X-Forwarded-For $proxy_add_x_forwarded_for;

The backend program can obtain the user's IP address from the Server variable HTTP_X_REAL_IP and HTTP_X_FORWARDED_FOR.

The value of HTTP_X_REAL_IP is the user REMOTE_ADDR that nginx gets





Previous:Nginx on the front-end and Apache on the back-end obtain the user's real IP address
Next:The front-end nginx and back-end nginx server records the IP address of the original client
