这里使用的版本是1.20.4，最好与集群版本一直，可使用kubectl get node查看
[root@k8s ~]# yum install kubectl-1.20.4-0 -y
[root@k8s ~]# mkdir ~/.kube
scp到master节点，我这里master节点hosts表域名是k8s-master，用户是student
[root@k8s ~]# scp student@k8s-master:/home/studnet/.kube/* ~/.kube
[root@k8s ~]# echo "export KUBECONFIG=$HOME/.kube/admin.conf" >> ~/.bash_profile
[root@k8s ~]# echo "source <(kubectl completion bash)" >> ~/.bash_profile
[root@k8s ~]# source ~/.bash_profile
