部署keepalived+nginx高可用，没有配置使用脚本是正常的，但是用上vrrp\_script，就不行了。

其实这个问题估计也就是在centos系统上出现吧，是不是没有去校验过，Failed to dynamic link an ipset function - /lib64/libipset.so: undefined symbol: ipset\_session\_error这个问题其实keepalived已经修复了，但是，用linux系统的人，都喜欢打指令安装软件，yum install keepalived,或者加上-y，就算你更新数据源，centos拿到最新的keepalived的版本都是v1.3.5,其他地方没问题，但是配置用上了vrrp\_script的话就会出错，所有只能自己到官网下载包来make就正常可用了。记得加上script\_user root  
和enable\_script\_security。
