The loading.abc.com and loading.xyz.com domain names all point to the IP address of the nginx server, the user accesses the [url] http://loading.abc.com [/url], load balancing its load to 192.168.1.2: 80, 192.168.1.3: 80, 192.168.1.4: 80, 192.168.1.5: 80 four servers. The user accesses the [url] http://loading.xyz.com [/url] and balances its load to ports 8080, 8081, and 8082 on the 192.168.1.7 server.
