What is reverse proxy?

A reverse proxy is a proxy server that accepts connection requests from the Internet and forwards the requests to an internal (or other) network server, return the result obtained from the server to the client requesting connection from the Internet.

Implementation method:

For example, if I want to create A domain name www.linuxidc.com on Linux VPS for reverse proxy access to twitter, I first add A record to the VPS IP address for the domain name www.linuxidc.net on the domain name management at the domain name registrar, modify the Nginx configuration file on VPS and add the following:

Server
{
Listen 80;
Server_name www.linuxidc.com;

Location /{
Proxy_pass http://twitter.com /;
Proxy_redirect off;
Proxy_set_header X-Real-IP $ remote_addr;
Proxy_set_header X-Forwarded-For $ proxy_add_x_forwarded_for;
}
} After the configuration is added, run:/usr/local/nginx/sbin/nginx-t to check whether the configuration is normal. if: the configuration file/usr/local/nginx/conf/nginx. conf syntax is OK configuration file/usr/local/nginx/conf/nginx. conf test is successful. otherwise, modify the configuration according to the error message.

Run kill-HUP 'cat/usr/local/nginx/logs/nginx. pid 'to make the configuration take effect. after domain name resolution takes effect, you can access twitter through www.linuxidc.net.
