       不多说了，rancher界面报错如下：

当前集群Provisioning中...，在API准备就绪之前，直接与API交互的功能将不可用。[controlPlane] Failed to bring up Control Plane: [Failed to verify healthcheck: Service [kube-apiserver] is not healthy on host [172.16.0.251]. Response code: [401], response body: {"kind":"Status","apiVersion":"v1","metadata":{},"status":"Failure","message":"Unauthorized","reason":"Unauthorized","code":401} , log: E0814 06:01:46.422755 1 authentication.go:65] Unable to authenticate the request due to an error: [x509: certificate signed by unknown authority, x509: certificate signed by unknown authority (possibly because of "crypto/rsa: verification error" while trying to verify candidate authority certificate "kube-ca")]]

       目前还没有找到原因...这几天应该会出来。
