问题“The connection to the server....:6443 was refused - did you specify the right host or port?”的处理！

问题“The connection to the server <master>:6443 was refused - did you specify the right host or port?”的处理！

一、故障产生

在不关闭kubernets相关服务的情况下，对kubernets的master节点进行重启。（模拟服务器的异常掉电）

二、故障状况

启动后无法远程到kubernets的dashbaord，后进行如下命令报错。

# kubectl get nodes
The connection to the server <master>:6443 was refused - did you specify the right host or port?

故障处理：

1.检查环境变量情况（正常）

# env | grep -i kub

2.检查docker服务（正常）

# systemctl status docker.service

3.检查kubelet服务（表面正常）

# systemctl status kubelet.service

4.查看端口是是否被监听（没有监听）

# netstat -pnlt | grep 6443

5.检查防火墙状态（正常）

# systemctl status firewalld.service

6.查看日志

# journalctl -xeu kubelet

这里分析，应该是镜像的问题。

6.1 重新导入一下API镜像即可。

# docker load -i kube-apiserver-amd64_v1.9.0.tar

6.2 重启docker和kubelet服务

# systemctl restart docker.service# systemctl restart kubelet.service

6.3 检查服务（此时正常）

# kubectl get nodes

至此，故障处理完成。
