[root@centos8 ~]yum install keepalived -y

[root@centos8 ~]systemctl start keepalived.services

[root@centos8 ~]systemctl status keepalived.service

　　

在虚拟机系统上yum 安装Keepalivedy启动时报错，原因是配置文件中网卡的名称和虚拟中的名称不对照。

vi /etc/keepalived/keepalived.conf

修改为实际网卡名称。再次执行.systemctl start keepalive.service

keepalived成功启动。
