The connection to the server localhost:8080 was refused - did you specify the right host or port? 问题1 kube-apiserver启动失败

admin.conf 配置无关（没有也没关系）
systemctl status kube-apiserver
systemctl start kube-apiserver

问题2 admin.conf 配置问题

添加 admin.conf 文件到配置文件

vim /etc/profile
在底部增加新的环境变量
export KUBEConFIG=/etc/kubernetes/admin.conf

生效配置
source /etc/profile
