一、执行kubectl报错
-rw------- 1 root root 5432 1月 4 11:29 scheduler.conf [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/kubernetes/admin.conf $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
[root@localhost kubernetes]# kubectl get nodes NAME STATUS ROLES AGE VERSION localhost Ready master 9h v1.18.5 redis-01.hlqxt Ready <none> 4h51m v1.18.5 redis-02.hlqxt Ready <none> 4h4m v1.18.5 redis-03.hlqxt Ready <none> 4h4m v1.18.5
