一、理论
1.各组件服务重启命令
（1）Master节点+Node节点共同服务
systemctl restart etcd
systemctl daemon-reload
systemctl enable flanneld
systemctl restart flanneld（2）Master节点独有服务
systemctl daemon-reload
systemctl enable kube-apiserver
systemctl restart kube-apiserver
systemctl daemon-reload
systemctl enable kube-controller-manager
systemctl restart kube-controller-manager
systemctl daemon-reload
systemctl enable kube-scheduler
systemctl restart kube-scheduler（3）Node节点独有服务
systemctl daemon-reload
systemctl enable kubelet
systemctl restart kubelet（status状态为 not ready时候重启即可）
systemctl daemon-reload
systemctl enable kube-proxy
systemctl restart kube-proxy
systemctl status etcd
systemctl status flanneld
systemctl status kube-apiserver
systemctl status kube-controller-manager
systemctl status kube-scheduler
systemctl status kubelet
systemctl status kube-proxy
