  • k8s The connection to the server localhost:8080 was refused

    [root@k8s-node1 etc]# kubectl get nodes
    The connection to the server localhost:8080 was refused - did you specify the right host or port?

    1. 将主节点(master节点)中的【/etc/kubernetes/admin.conf】文件拷贝到从节点相同目录下:

      [root@k8s-master ~]# scp -r /etc/kubernetes/admin.conf 192.168.56.134:/etc/kubernetes/admin.conf
      The authenticity of host '192.168.56.134 (192.168.56.134)' can't be established.
      ECDSA key fingerprint is SHA256:ZqLi8R+OEmURjHPPyQzqgumohnPo3te3jlVsuDfi7P0.
      ECDSA key fingerprint is MD5:23:89:08:37:c1:53:8f:16:1f:91:6e:3b:64:1e:b0:6f.
      Are you sure you want to continue connecting (yes/no)? yes
      Warning: Permanently added '192.168.56.134' (ECDSA) to the list of known hosts.
      root@192.168.56.134's password:
      admin.conf

    2. 修改node节点环境变量 vi  .bash_profile  export KUBECONFIG=/etc/kubernetes/admin.conf
    3. 生效  source  .bash_profile
    4. 问题解决:

      [root@k8s-node1 ~]# kubectl get nodes
      NAME STATUS ROLES AGE VERSION
      k8s-master Ready master 5h19m v1.19.0
      k8s-node1 Ready <none> 5h16m v1.19.0
