关机过程
0.node节点
[root@dn02 ~]# systemctl stop kube-proxy
[root@dn02 ~]# systemctl stop kubelet
1.master
[root@dn01 ~]# systemctl stop kube-scheduler
[root@dn01 ~]# systemctl stop kube-controller-manager
[root@dn01 ~]# systemctl stop kube-apiserver.service
2.关闭 node节点的flanneld 服务
[root@dn02 ~]# systemctl stop flanneld
3.全部节点关闭etcd
[root@dn0X~]# systemctl stop etcd
[root@dn0X ~]# systemctl stop docker
4.全部关机
[root@dn01 ~]# init 0
开机过程
systemctl start etcd 三节点
systemctl start flanneld （node 节点）
systemctl start kube-apiserver.service (默认设置了开机启动， master 节点)
systemctl start kube-scheduler （默认设置了开机启动， master 节点）
systemctl start kube-controller-manager （默认设置了开机启动， master 节点）
systemctl start kubelet（node 节点）
systemctl stop kube-proxy（node 节点）
