#sudo cp /usr/src/keepalived-2.2.4/keepalived/keepalived.service /usr/lib/systemd/system/keepalived.service

#keepalived -t //测试keepalived配置

#sudo systemctl start keepalived.service

#sudo systemctl enable keepalived.service

使用命令验证

#systemctl status keepalived.service

#hostname -I //查看虚拟IP在哪个节点上

#ip a //查看网卡的IP
