The cause of error most likely in that that dns does not return ip the server for the name 
(command nslookup <server_name> the IP address should be returned).

造成错误的原因可能是dns没有返回服务名的IP，可能是hosts原因

经查看/etc/hosts为空，因此可以大概确定导致的错误原因

给添加hosts

127.0.0.1  localhost.localdomain   localhost

162.20.1.99   HXZG

以上内容后，安装顺利进行
