ifconfig eth0 192.168.25.209/22 up
ifconfig eth0:0 192.168.26.210 netmask 255.255.255.255 broadcast 192.168.26.210 up
route add -host 192.168.26.210 dev eth0:0
route -n

回到Directory进行LVS配置：
ipvsadm -A -t 192.168.26.210:80 -s rr
ipvsadm -a -t 192.168.26.210:80 -s 192.168.25.210 -g
ipvsadm -a -t 192.168.26.210:80 -s 192.168.25.211 -g
ipvsadm -a -t 192.168.26.210:80 -s 192.168.25.212 -g
