一、安装过程，参照 尚硅谷的安装流程：https://www.yuque.com/leifengyang/oncloud/ghnb83 我是一个master节点和2个从节点
1.从节点报错：The connection to the server localhost:8080 was refused - did you specify the right host or port?
解决方案参考： https://www.cnblogs.com/wangzy-Zj/p/13958054.html
2. calico.yaml 下载失败
解决方案:换个链接 curl https://docs.projectcalico.org/v3.20/manifests/calico.yaml -O
