执行keepAlived命令

service keepalived start

报错如下:

Starting keepalived (via systemctl):  Job for keepalived.
service failed because the control process exited with error 
code. See "systemctl status keepalived.service" and "journalctl -xe" for details.[失败]

原因
/usr/sbin/创建keepalived软链接有问题，需要删除，重新从你创建的keepalived/sbin/目录中将keepalived文件创建软链接到/usr/sbin目录

自己在创建keepalived软链接时，使用的是以下命令

ln -s /usr/local/sbin/keepalived /usr/sbin/

后来才发现软链接创建错误，以下是解决方案

解决方法：
1.删除掉从/usr/sbin/中

rm /usr/sbin/keepalived

2.创建新的软链接

ln -s /usr/local/keepalived/sbin/keepalived /usr/sbin/

输入yes确定删除

重新启动

service keepalived start

查看keepAlived运行状态(成功如图)

ps aux |grep 'keepalived'
