  master的kube-apiserver启动失败

   使用命令检查集群报错如下

# kubectl get node
error: You must be logged in to the server (the server has asked for the client to provide credentials)

 

  kube-apiserver日志没有报错

  查看系统日志-i是不区分大小写

cat /var/log/messages|grep kube-apiserver|grep -i error

   发现如下报错

Error: failed to create listener: failed to listen on 127.0.0.1:8080: listen tcp 127.0.0.1:8080: bind: address already in use

   其他应用占用了8080端口

  经过检查发现是 heketi服务占用了该端口停止就可以了
