如何使用 BIND 和域名服务器创建子域名

Question

我想了解 DNS 和配置域。使用 cpanel 配置很简单，但我想使用 BIND 工具在服务器上配置。如何使用名称服务器绑定子域，例如测试域名.com

错误名称未解决

我从一家托管公司购买了一个域名。

ns1.xxxxx.com  
ns2.xxxxx.com

文件内容：/etc/named.conf

    listen-on port 53 { any; };
    listen-on-v6 port 53 { ::1; };

    allow-query     { any; };
    recursion no;

    dnssec-enable yes;
    dnssec-validation yes;

logging {
        channel default_debug {
                file "data/named.run";
                severity dynamic;
        };
};

zone "." IN {
    type hint;
    file "named.ca";
};

include "/etc/named.rfc1912.zones";
include "/etc/named.root.key";
