问题见
PIDFile=/usr/local/program/keepalived/var/run/keepalived.pid ##发现这个目录不存在，无法写入keepalived.pid
修改成

PIDFile=/var/run/keepalived.pid

运行命令
systemctl daemon-reload #重新载入 systemd，扫描新的或有变动的单元

在运行就Ok了
service keepalived start
Starting keepalived (via systemctl): [ OK ]

后面
把浮动ip改成119，后续OK
（为啥我之前配180也可以？）

0730 脑裂问题

重启keepalived服务：

只有从节点有浮动ip，脑裂问题消失。

重启机器 测试，也是一样的，只有主有浮动ip。

关闭主节点的keepalived：
浮动ip切换到备节点

linux里的bootproto的none,static,dhcp有什么区别

这个是网络配置参数：
BOOTPROTO=static 静态IP

BOOTPROTO=dhcp 动态IP

BOOTPROTO=none 无（不指定）
通常情况下是dhcp或者static，通过指定方式的办法来获得地址，如果没有指定的话可能会出现问

keepalived绑定的ip一段时间（大约几分钟）后消失的问题
我用keepalived将ip地址绑定到单独的一块网卡eth1，该网卡未分配任何ip地址。keepalived启动后，ip地址绑定正常。但过了几分钟后，绑定的ip地址就消失了。检查keepalived日志未发现异常。

接着检查系统其他日志，在/var/log/messages中看到，每隔几分钟分钟就会有一条dhcpclient的日志。据此猜测是启用的eth1的dhcp功能导致的keepalived绑定的ip在一段时间（大约几分钟）后消失。

修改配置文件/etc/sysconfig/network-scripts/ifcfg-eth1，设置BOOTPROTO=none。重启服务service network restart和service keepalived restart后，ip地址不在丢失，服务器工作正常。
