the connection to the server 6443 was refused - did you specify the right host or port? 问题的解决方法
问题产生
k8s 虚拟机重启之后,使用 kubectl get nodes 命令报出如下错误:
# kubectl get nodes The connection to the server <master>:6443 was refused - did you specify the right host or port?
解决方法:
1. 编辑 /etc/profile
vim /etc/profile
2. 在里面添加:
export KUBECONFIG=/etc/kubernetes/admin.conf
3. 使生效
source /etc/profile
4. 关机重启一下
