1、安装httpd服务，并设定页面信息为===21===
# vim /var/www/html/index.html
# cat /var/www/html/index.html
===21=== 2、配置环境，可以直接写一个脚本运行下就好了
# cat skp.sh
#!/bin/bash
#

case $1 in
start)
echo 1 > /proc/sys/net/ipv4/conf/all/arp_ignore

echo 2 > /proc/sys/net/ipv4/conf/all/arp_announce
echo 2 > /proc/sys/net/ipv4/conf/lo/arp_announce
ifconfig lo:0 $vip netmask 255.255.255.255 broadcast $vip
route add -host $vip dev lo:0

stop)
echo 0 > /proc/sys/net/ipv4/conf/all/arp_ignore

ifconfig lo:0 del $vip

三、RS2配置
1、安装httpd服务，并设定页面信息为===30===
# vim /var/www/html/index.html
# cat /var/www/html/index.html
===30===
2、配置环境，可以直接写一个脚本运行下就好了
# cat skp.sh
#!/bin/bash
#

case $1 in
start)
echo 1 > /proc/sys/net/ipv4/conf/all/arp_ignore

四、在Director查看下VIP的MAC地址
# ifconfig #我们发下VIP的MAC地址为：00:0C:29:AD:98:5C 与上面的一致
eth0 Link encap:EthernetHWaddr 00:0C:29:AD:98:5C

TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:0
RX bytes:0 (0.0 b)TX bytes:0 (0.0 b)五、在其他机子ping测试并arp看下MAC地址对不对，并且curl访问测试
# ping 192.168.11.17 #ping VIP地址
PING 192.168.11.17 (192.168.11.17) 56(84) bytes of data.
