安装KubeSphere最好的方法就是参考官方文档，而且官方文档是中文的。
官网地址：https://kubesphere.com.cn/
https://github.com/kubesphere/kubesphere/blob/master/README_zh.md
安装提前条件：
使用 Kubeadm 部署 Kubernetes(K8S) 安装--附K8S架构图
使用 Kubeadm 部署 Kubernetes(K8S) 安装 -- 持久化存储(NFS网络存储)
Kubernetes(K8S) 安装 Metrics-Server
# 检查 K8S 版本，低版本需要升级 [root@k8smaster kubesphere]# kubectl version
安装

如果出现下面错误，需要安装 storageclass、persistentVolumeClaim
