'$ Status $ body_bytes_sent "$ http_referer "'

'"$ Http_user_agent" "$ http_x_forwarded_for "';

Access_log logs/access. log main;

Upstream proxy_test {

Server 192.168.4.69: 80; # If you want to test it, replace it with the ip address of the proxy backend.

Server 192.168.4.68: 80;

}

This is the server Segment configuration

Server {

Listen 80;

Server_namewww.test.com; # The domain name to be accessed. The test domain name I use here

Charset utf8;

Location /{

Proxy_pass http: // proxy_test;

Proxy_set_header Host $ host;

}

}

Nginx smooth restart: nginx-s reload # load the configuration just added.

VII. test:

Start the server on the backend and set the test file test.html on the page files 192.168.4.69and 68. the content is this is test 69, this is test 68, which makes it easy to see which server is accessed.

Configure the host locally and use www.test.com to access the files on the backend server,

For example, www.test.com/test.html,

This is displayed in the browser, indicating that the configuration is OK.
