用戶訪問http://www.net-hb.com.cn，將其負載均衡到192.168.1.2:80、192.168.1.3:80、192.168.1.4:80、192.168.1.5:80四臺服務器。
用戶訪問//m.survivalescaperooms.com，將其負載均衡到192.168.1.7服務器的8080、8081、8082端口。
以下為配置文件nginx.conf：

二、安裝PHP 5.2.4(FastCGI模式)
4、創建www用戶和組，以及其使用的目錄：
三、安裝Nginx 0.5.31
1、安裝Nginx所需的pcre庫：
2、安裝Nginx
3、創建Nginx日志目錄
5、啟動Nginx
