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 ~]#
2、安装epel源，方便后面安装keepalivedyum install epel-release -y
3、使用yum安装keepalivedyum install keepalived
4、输入y并回车继续安装
5、让keepalived开机自启动systemctl enable keepalived
6、ll /etc/keepalived/keepalived.confkeepalived.conf
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
