k8s的node节点，执行kubectl get XXX报错

报错现象：

[root@localhost ~]# kubectl get nodes
The connection to the server localhost:8080 was refused - did you specify the right host or port?

但是也想让子节点可以查询，因此研究了一下

把master下面的admin.conf移到子节点相同路径下

[root@localhost manifests]#  cd /etc/kubernetes
[root@localhost kubernetes]# ll
