    7.  进入 192.168.1.232
        把下面四句添加在/etc/sysctl.conf  文件最后：
      net.ipv4.conf.lo.arp_ignore = 1
         net.ipv4.conf.lo.arp_announce = 2
         net.ipv4.conf.all.arp_ignore = 1
         net.ipv4.conf.all.arp_announce = 2
         // 以上关闭arp

我觉得这里有点问题，arp_ignore和arp_announce是应用在与VIP相连的网卡上的：

On the realservers the VIP will still be on lo (as for the hidden method). If the reply packets to the client are routed through eth0, then the arp announcements/requests are made through eth0 and you will apply the arp_ignore/arp_announce sysctls to eth0, not to lo (you cannot use arp_ignore/arp_announce on lo).

/etc/sysctl.conf
net.ipv4.conf.eth0.arp_ignore = 1
net.ipv4.conf.eth0.arp_announce = 2
net.ipv4.conf.all.arp_ignore = 1
net.ipv4.conf.all.arp_announce = 2
