keepalive重启服务器报错如下：

#systemctl status keepalived
● keepalived.service - LVS and VRRP High Availability Monitor
   Loaded: loaded (/usr/lib/systemd/system/keepalived.service; disabled; vendor preset: disabled)

May 26 02:10:50 ka1 systemd[1]: Unit keepalived.service entered failed state.

我这是因为keepalived的配置文件错误的添加了执行权限，导致无法启动，去掉执行权限就行

chmod -x keepalived.conf

也有可能是进程没关闭，尝试杀进程试试看

pkill keepalived
