1、操作系统的版本是centos7.6[root@localhost ~]# cat /etc/redhat-release CentOS Linux release 7.6.1810 (Core) [root@localhost ~]#
3、使用yum安装keepalivedyum install keepalived
5、让keepalived开机自启动systemctl enable keepalived
7、采用默认的配置文件是无法启动keepalived服务的，可以通过tail -fn500 /var/log/messages命令查看报错日志systemctl start keepalived最好是能根据实际业务配置keepalived.conf
