bind 无法启动，也不会显示错误

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 ：

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
