不知道怎么用着用着，使用kubectl 时报错，错误如下：
root@R740--:~# kubectl get pod
The connection to the server 107.105.136.28: was refused - did you specify the right host or port?

6443是Kubernetes集群APIServer的端口，因此猜测是APIServer挂掉了，因此查看正在运行的进程
$ps -aux | grep "kube"
发现果然没有有关的进程，因此重启相关的服务
$systemctl restart kube-apiserver
$systemctl restart kube-controller-manager
$systemctl restart kube-scheduler
查看状态，可以使用kubectl命令了
root@R740--:~# kubectl get componentstatus
NAME STATUS MESSAGE ERROR
scheduler Healthy ok
controller-manager Healthy ok
etcd- Healthy {"health":"true"}
etcd- Healthy {"health":"true"}
