1. If the Nginx server is used as the web server, after the load balancer and the Nginx reverse proxy, the real ip address of the client cannot be obtained. The reason is that after the reverse proxy, due to the addition of an intermediate layer between the client and the server, the web server cannot get the client's ip directly, and the ip address of the reverse proxy will be passed through the $remote_addr variable. However, the reverse proxy server can add X-Forwarded-For information to the HTTP header information of the forwarding request to record the original client ip address of the original client request server address.
