DNS 无法访问 ;; Got SERVFAIL reply from*** ， trying next server（数据配置文件权限导致）

问题现象：

搭建了DNS服务器后，访问被拒绝

[root@localhost opt]# nslookup www.wangzy.com
;; Got SERVFAIL reply from 192.168.43.12, trying next server
;; connection timed out; trying next origin
;; Got SERVFAIL reply from 192.168.43.12, trying next server
;; connection timed out; no servers could be reached

原因：书写数据配置文件时，默认给与的配置文件权限不对

 

解决办法：

添加对应权限，重启服务器

 

 

再次访问成功：
