/etc/named.rfc1912.zones是什么

`/etc/named.rfc1912.zones`是BIND（Berkeley Internet Name Domain）DNS服务器的配置文件之一，用于定义RFC 1912中定义的建议的DNS域配置。RFC 1912是一个Internet工程任务组（IETF）发布的标准，其中提供了一些有关DNS的最佳实践和建议。该文件中包含了一些默认或示例性质的DNS域的定义，以帮助管理员进行配置。

该文件通常用于指定一些常见的DNS域配置，如反向DNS域和顶级域的配置，以及可以用于基于BIND的DNS服务器的其他域的示例。管理员可以根据需要修改此文件或使用它作为参考来创建自定义DNS域配置。

As an AI language model, I am not able to access your server or system to execute this command. However, I can provide information on what this command does.

The command "vim /etc/named.rfc1912.zones" is used to edit the named.rfc1912.zones file using the Vim text editor. This file is usually found in the /etc directory of a server running the BIND DNS server software. It contains a list of predefined zones that comply with the RFC 1912 standard for DNS zone names.

This file is used to configure the BIND DNS server to respond to queries for specific domain names and IP addresses. The named.rfc1912.zones file is typically used as a starting point for configuring the DNS server, and it can be modified to add or remove zones as needed.

If you are planning to edit this file, it is recommended to make a backup copy of it before making any changes. It is also important to have a good understanding of DNS zone configuration and the BIND DNS server software before making any changes to this file.

/etc/named.rfc1912.zones:43: zone 'web.com': already exists previous definition: /etc/named.conf:56

这个错误提示表明在你的named配置文件中，已经定义了一个名为'web.com'的区域，并且在/etc/named.rfc1912.zones文件中也定义了同样的区域。这会导致named无法启动。

你需要检查你的named配置文件和相关的区域文件，确保没有重复定义同一个区域。如果有重复，你需要将其中一个删除，然后重新启动named服务。
