我正在推出外部 DNS 服务器以解决所有最终用户查询
在我们将解决方案投入生产之前,我希望尽可能多地进行有用的日志记录
这是 named.conf 文件(命名空间称为 gi-named.conf 文件)

/*
- 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

我遇到的问题是,当我看到填充 /var/named/log/queries 文件的日志时,我在 /var/named/log/query-error 日志文件或 /var/named/log 中都看不到任何日志/default 日志文件,我不确定我到底哪里出错了,或者我是否遗漏了一些配置
任何人以前经历过这种情况吗?
所以问题似乎是我试图创建的日志文件和日志通道在我使用的绑定版本中不可用。
我运行了 yum update bind-utils,它让我进入了 9.11 版本。
自更新以来,所有日志记录通道都正常工作
