我想在node02执行kubectl命令但是报了The connection to the server localhost:8080 was refused - did you specify the right host or port?的错。

[root@node02 ~]# kubectl get pod

The connection to the server localhost:8080 was refused - did you specify the right host or port?

经过排查，发现是node02节点没有权限，那我就赋予node02权限

首先在master执行以下命令

scp /etc/kubernetes/admin.conf 10.0.0.50:/etc/kubernetes/admin.conf

会提示你

The authenticity of host '10.0.0.50 (10.0.0.50)' can't be established.

ECDSA key fingerprint is SHA256:ZpGuu/ydQ7uzTgleQEEK4qLI2KdjyElMFW7YEuoiOFk.

ECDSA key fingerprint is MD5:1a:af:70:98:ad:cf:14:ac:8b:05:24:e0:43:41:c9:08.

Are you sure you want to continue connecting (yes/no)?

填yes，注意是yes，不是y

会提示你

Warning: Permanently added '10.0.0.50' (ECDSA) to the list of known hosts.

root@10.0.0.50's password:

输入node02的密码即可

admin.conf 100% 5568 3.4MB/s 00:00

传输成功

接下来传输第二个文件

scp /etc/kubernetes/admin.conf 10.0.0.50:/etc/kubernetes/admin.conf

输入密码

admin.conf 100% 5568 2.6MB/s 0

传输成功

接下来在node02节点操作

export KUBECONFIG=/etc/kubernetes/admin.conf

echo "export KUBECONFIG=/etc/kubernetes/admin.conf" >> ~/.bash_profile

验证

[root@node02 ~]# kubectl get pod

成功！！！
