一 故障描述
我在台湾合作方给定的两台虚拟机上部署HAProxy+Keepalived负载均衡高可用方案。在配置完Keepalived后，重新启动Keepalived，Keepalived没有绑定VIP。

查看VIP绑定情况
$ ifconfig eth1:ha eth1:ha Link encap:Ethernet HWaddr 00:16:3E:F2:37:6B UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 Interrupt:13
没有VIP绑定
二 排查过程
1）检查VIP的配置情况
向合作方确认提供的VIP的详细情况
IPADDR 10.1.1.200
NETMASK 255.255.255.0
GATEWAY 10.1.1.1
Brodcast 10.1.1.255
