DNS解析问题；挖掘 SERVFAIL 错误

Question

我正在设置一台专用服务器进行托管。并尝试设置私人 DNS 和名称服务器。从一天开始尝试，我无法弄清楚这个问题。

我在 windows 8.

中使用 BIND9 DNS 服务器

所以，我在正确设置 DNS 时遇到了问题。我有两个域，每个域都指向其中一台服务器。名称服务器已在域注册商处正确注册，名称服务器 IP 也已正确输入。我已经与注册服务商的技术支持人员进行了交谈，他们确认一切都已在他们这边进行了设置。不太了解 DNS，我用 google 搜索了域名服务器和 DNS，直到我几乎失明，并花了几个小时搞乱配置。

named 运行良好，但没有解决任何问题。当我 "dig any example.com" 收到 SERVFAIL 消息时。

named.conf

options { 
    directory "C:\BIND\etc";
    version "not currently available"; 
    pid-file "run\named.pid"; 
    allow-transfer { none; }; 
    recursion no; 
 }; 

 logging{ 
    channel my_log{ 
        file "log\named.log" versions 3 size 250k;
        severity info; 
    }; 
    category default{ 
            my_log; 
    };
}; 

zone "example.com" IN { 
    type master; 
    file "zones\db.example.com.txt";
    allow-transfer { any; };
 }; 

 key "rndc-key" { 
    algorithm hmac-md5; 
    secret "B5jGB5sU7e35WzXoam/EcA=="; 
 }; 

 controls { 
    inet 127.0.0.1 port 953 
        allow { 127.0.0.1; } keys { "rndc-key"; };
 };

这里的1.2.3.4指的是我的public静态IP。我是 dns 的新手。任何帮助都会很棒。

所以，总结一下： •具有 IP 的名称服务器已在域名注册商处正确注册 •named 已配置且运行 ...并且不得配置 •正确，因为没有解决任何问题。

任何帮助都会很棒。我将文件中的域和 IP 更改为泛型，但如果您需要了解相关域，请告诉我。

您的日志显示错误：

127.0.0.1#953 no longer listening on 127.0.0.1#53 no longer listening on 192.168.1.3#53 exiting dns_rdata_fromtext: zones\db.example.com.txt:2: near eol: unexpected end of input zone example.com/IN: loading from master file zones\db.example.com.txt failed: unexpected end of input running shutting down: flushing changes stopping command channel on 127.0.0.1#953 no longer listening on 127.0.0.1#53 no longer listening on 192.168.1.3#53 exiting dns_rdata_fromtext: zones\db.example.com.txt:2: near eol: unexpected end of input zone example.com/IN: loading from master file zones\db.example.com.txt failed: unexpected end of input running shutting down: flushing changes stopping command channel on

它似乎不喜欢您的 SOA。您可以尝试将 hostmaster 记录移动到与您的 ORIGIN 和 NX TTL

之后的最后一个括号相同的行

编辑：

@   IN SOA  ns1.example.com. hostmaster.example.com. (
            2015062801
            10800
            3600
            604800
            86400 
    )
