Unable to construct api.Node object for kubelet: can't get ip address of node master.example.com: lookup master.example.com on : no such host

openshift首页进不去

启动openshift时报的错，大意是：

无法为kubelet构造api.Node对象：无法获取节点master.example.com的IP地址：

所以就联想到新装的centos，没有在网卡配置文件中配置固定IP

添加IPADDR=192.*.*.*

IP还跟默认分配的保持不变就好。

重新启动openshift，OK。
