一：
real_server 192.168.2.188 80 {
weight 1

url {
path /index.html
digest bfaa334fdd71444e45eca3b7a1679a4a #http://192.168.2.188/index.html的digest值 }
connect_timeout 3
nb_get_retry 3
delay_before_retry 3
}
digest值的获取方法：
[root@188-test html]# genhash -s 192.168.2.188 -p 80 -u /index.html
MD5SUM = bfaa334fdd71444e45eca3b7a1679a4a
