kubernetes centos7.2系统单机部署完成后，安装helm，执行**helm version**：
```shell
Client: &version.Version{SemVer:"v2.8.2", GitCommit:"a80231648a1473929271764b920a8e346f6de844", GitTreeState:"clean"}
Server: &version.Version{SemVer:"v2.8.2", GitCommit:"a80231648a1473929271764b920a8e346f6de844", GitTreeState:"clean"}
```
但是，执行**helm ls** ：
```shell
Error: Get http://localhost:8080/api/v1/namespaces/kube-system/configmaps?labelSelector=OWNER%3DTILLER: dial tcp 127.0.0.1:8080: getsockopt: connection refused
```
