kubeadm init问题

1、解析不到对应的主机

 [WARNING Hostname]: hostname "k8s-master-01" could not be reached
  [WARNING Hostname]: hostname "k8s-master-01": lookup k8s-master-01 on 192.168.222.2:53: no such host

　　

解决方式：

hostnamectl set-hostname k8s-master-01

[root@k8s-master-01 ~]# cat /etc/hosts
127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4 k8s-master-01
::1         localhost localhost.localdomain localhost6 localhost6.localdomain6 k8s-master-01
192.168.222.153 k8s-master-01
