我一直在使用 debian，因此 CentOS 7 中的情况有所不同。我尝试设置绑定，但是它无法启动。并且没有显示确切的错误。
错误 ：

- If you are building an AUTHORITATIVE DNS server, do NOT enable recursion.
- If you are building a RECURSIVE (caching) DNS server, you need to enable
recursion.
- If your recursive DNS server has a public IP address, you MUST enable access
control to limit queries to your legitimate users. Failing to do so will
cause your server to become part of large scale DNS amplification
attacks. Implementing BCP38 within your network would greatly
reduce such attack surface

有什么帮助吗？
答案1
我猜是DISABLE_ZONE_CHECKING环境变量。我猜你肯定在某个地方设置了它，这/etc/sysconfig/named只是猜测。
答案2
最后我终于搞明白了。实际上在我的named.conf文件中我使用了allow-query { localhost; my.ip; };，但我没有使用，allow-transfer所以我只是交换了。简而言之，我在我的文件中添加了以下内容named.conf
allow-query { any; };
allow-transfer { localhost; server.ip; };
现在它开始工作了。感谢@yoonix 给我的建议/var/log/messages
