网络拓扑图如下：  
![Center][]  
  
1. Director Server配置

[root@chen ~]# ifconfig eth0:1 192.168.10.100/32 broadcast 192.168.10.100 up
    [root@chen ~]# route add -host 192.168.10.100 dev eth0:1
    [root@chen ~]# ifconfig eth0:1 192.168.92.100/32 broadcast 192.168.92.100 up
    [root@chen ~]# route add -host 192.168.92.100 dev eth0:1
    [root@chen ~]# ipvsadm -A -t 192.168.92.100:80 -s wlc
    [root@chen ~]# ipvsadm -a -t 192.168.92.100:80 -g -r 192.168.92.131 -w 1
    [root@chen ~]# ipvsadm -a -t 192.168.92.100:80 -g -r 192.168.92.128 -w 2
    [root@chen ~]# ipvsadm -L -n
    IP Virtual Server version 1.2.1 (size=4096)
    Prot LocalAddress:Port Scheduler Flags
      -> RemoteAddress:Port           Forward Weight ActiveConn InActConn
    TCP  192.168.92.100:80 wlc
      -> 192.168.92.128:80            Route   2      0          0         
      -> 192.168.92.131:80            Route   1      0          0         
    [root@chen ~]# service ipvsadm save
    ipvsadm: Saving IPVS table to /etc/sysconfig/ipvsadm:      [确定]

2. Real Server1的配置

[root@chen ~]# echo 1 > /proc/sys/net/ipv4/conf/lo/arp_ignore 
    [root@chen ~]# echo 2 > /proc/sys/net/ipv4/conf/lo/arp_announce 
    [root@chen ~]# echo 1 > /proc/sys/net/ipv4/conf/all/arp_ignore 
    [root@chen ~]# echo 2 > /proc/sys/net/ipv4/conf/all/arp_announce 
    [root@chen ~]# ifconfig lo:0 192.168.92.100/32 broadcast 192.168.92.100 up
    [root@chen ~]# route add -host 192.168.92.100 dev lo:0
    [root@chen ~]# ifconfig
    eth0      Link encap:Ethernet  HWaddr 00:0C:29:FB:8C:5C  
              inet addr:192.168.92.128  Bcast:192.168.92.255  Mask:255.255.255.0
              inet6 addr: fe80::20c:29ff:fefb:8c5c/64 Scope:Link

3. Real Server2的配置与Real Server1的配置一样，ip为192.168.92.131  
4. 测试  
客户端浏览器输入 http://192.168.92.100/index.html
