Nginx simple load balancing configuration example

The user accesses http:// www.net.com.cn and loads it to four servers: 192.168.1.2:80, 192.168.1.3:80, 192.168.1.4:80, and 192.168.1.5:80.
The user accesses // www.jb51.net and loads it to ports 8080, 8081, and 8082 of the 192.168.1.7 server.
The following is the configuration file nginx.conf:

# error_log logs/error. log;
# error_log logs/error log notice;
