解决办法

[root@k8s-master ~]#cd /etc/kubernetes/manifests/
[root@k8s-master /etc/kubernetes/manifests]#ls
etcd.yaml  kube-apiserver.yaml  kube-controller-manager.yaml  kube-scheduler.yaml

 将两个配置文件的- --port=0前边加上#号注释掉
[root@k8s-master /etc/kubernetes/manifests]#vim kube-controller-manager.yaml
[root@k8s-master /etc/kubernetes/manifests]#vim kube-scheduler.yaml

重启kubelet服务

[root@k8s-master /etc/kubernetes/manifests]#systemctl restart kubelet.service

再次查看cs状态
