1、操作系统的版本是centos7.6
[root@localhost ~]# cat /etc/redhat-release
陕包新
CentOS Linux release 7.6.1810 (Core)[root@localhost ~]#
2、安装epel源，方便后面安装keepalived
yum install epel-release -y
3、使用yum安装keepalived
yum 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.conf
keepalived.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命令查看报昆场错日志
systemctl start keepalived
最好是能根据实际业务配陵宋置keepalived.conf
