k8s执⾏kubectl相关命令报错：Unabletoconnecttotheserver。。。
⼀、执⾏kubectl报错

[root@localhost kubernetes]# kubectl get nodes
Unable to connect to the server: x509: certificate signed by unknown authority (possibly because of "crypto/rsa: verification error"while trying to verify candidate authority certificate "kubernetes") [root@localhost kubernetes]# kubectl get svc
Unable to connect to the server: x509: certificate signed by unknown authority (possibly because of "crypto/rsa: verification error"while trying to verify candidate authority certificate "kubernetes")⼆、重新执⾏以下命令
[root@localhost kubernetes]# mkdir -p $HOME/.kube
[root@localhost kubernetes]# cp -i /etc/f $HOME/.kube/config
cp：是否覆盖"/root/.kube/config"？ y
[root@localhost kubernetes]# chown $(id -u):$(id -g) $HOME/.kube/config
三、测试解决问题
unable[root@localhost kubernetes]# kubectl get nodes
