二进制部署k8s集群，启动apiserver服务时报错8080端口拒绝

Question

[root@node01 ~]# kubectl create clusterrolebinding kubelet-bootstrap --clusterrole=system:node-bootstrapper --user=kubelet-bootstrap
error: failed to create clusterrolebinding: Post "http://localhost:8080/apis/rbac.authorization.k8s.io/v1/clusterrolebindings?fieldManager=kubectl-create": dial tcp [::1]:8080: connect: connection refused
这个问题怎么解？
