两台机器，分别充当LVS+reaserver

A：10.0.0.10
B：10.0.0.20

配置如下
lvs执行
#!/bin/bash
VIP=192.168.1.252
RIP1=10.0.0.10
RIP2=10.0.0.20
/sbin/rc.d/init.d/functions
case "$1" in
start)
      echo "start LVS of DirectorServer"
      #Set the Virtual IP Address
      /sbin/ifconfig eth0:1 $VIP broadcast $VIP netmask 255.255.255.255 up
      /sbin/route add -host $VIP dev eth0:1
      #Clear IPVS Table
      /sbin/ipvsadm -C
      #Set Lvs
      /sbin/ipvsadm -A -t $VIP:80 -s wrr
      /sbin/ipvsadm -a -t $VIP:80 -r $RIP1:80 -g
      /sbin/ipvsadm -a -t $VIP:80 -r $RIP2:80 -g
      #Run Lvs
      /sbin/ipvsadm
;;
stop)
echo "Close LVS Directorserver"
/sbin/ifconfig eth0:1 down
/sbin/ipvsadm -C
;;
*)
echo "Usage 0{start|stop}"
exit 1
esac

reaserver上执行的。
#!/bin/bash
      VIP=192.168.1.252
      /sbin/ifconfig lo:0 $VIP broadcast $VIP netmask 255.255.255.255 up
      /sbin/route add -host $VIP dev lo:0
      echo "1">/proc/sys/net/ipv4/conf/default/arp_ignore
      echo "2">/proc/sys/net/ipv4/conf/default/arp_announce
      echo "1">/proc/sys/net/ipv4/conf/all/arp_ignore
      echo "2">/proc/sys/net/ipv4/conf/all/arp_announce
      sysctl -p

我停止其中一个WEB服务时，ipvsadm -ln  查看。  停掉的WEB服务IP还存在。。

但是 master 和backup是正常的。停掉master，backup能正常接管。

求助。。
