二：解决流程：
2.1：更新 kubeconfig：
2.1.1：执行命令：
export KUBECONFIG=/root/.kube/config
chmod g-r /root/.kube/config
2.2：再次执行之前的异常命令：
[root@vboxnode3ccccccttttttchenyang ~]# kubectl get deployment
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@vboxnode3ccccccttttttchenyang ~]# kubectl apply -f calico.yaml
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")
2.3：k8s配置操作config相关命令：
这一步应该在安装K8S kubeadm init后面执行，之前安装忘记这一步。
mkdir -p $HOME/.kubesudo cp -i /etc/kubernetes/admin.conf $HOME/.kube/configsudo chown $(id -u):$(id -g) $HOME/.kube/config
[root@vboxnode3ccccccttttttchenyang ~]# mkdir -p $HOME/.kube
[root@vboxnode3ccccccttttttchenyang ~]#
[root@vboxnode3ccccccttttttchenyang ~]# sudo cp -i /etc/kubernetes/admin.conf $HOME/.kube/config
cp：是否覆盖"/root/.kube/config"？ y
[root@vboxnode3ccccccttttttchenyang ~]# sudo chown ( i d − u ) : (id -u): (id−u):(id -g) $HOME/.kube/config
在这里插入图片描述
2.4：重新执行之前操作失效命令：
可以看见都已经生效：
kubectl get nodes -o wide
kubectl apply -f calico.yaml
[root@vboxnode3ccccccttttttchenyang ~]# kubectl get nodes -o wide
