通过我的域名注册局查询 DNS 服务器没问题。但浏览器无法通过其地址获取我的网站

  • 772

当我通过.com**顶级域名注册处的网站查询我的DNS服务器时，我可以看到我的DNS服务器找到了：

Query
Domain: example**.com**
Answer:
Following name-servers have been defined in **NIC DNS for your domain:

1. ns.example**.com**

IP addresses defined for NS servers in **NIC DNS (glue records):

1. ns.example**.com**. *4.*41.2*.1*4

Name Server: "ns.example**.com**"
List of defined name-servers in this name server is SYNC with the list of name-servers which has been defined in **NIC name-server.

List of name-server from this server:

1. ns.example**.com**

SOA detail from this server:

localhost. root.localhost. (
                    2021053002  ; Serial
                    10800   ; Refresh
                    3600    ; Retry
                    604800  ; Expire
                    86400 ) ; Minimum TTL

但在任何网络上，网络浏览器都无法通过example**.com**地址显示我的网站。

我有哪些选项可以调试我的 DNS 服务器？谢谢！

更新

我可以通过 SSH 连接到服务器并运行以下命令：

user@localhost:~> nslookup example**.com** 8*.*41.*3.1*4
;; connection timed out; no servers could be reached

还有这个命令：

user@localhost:~> nslookup example**.com** 
Server:         1.1.1.1
Address:        1.1.1.1#53

    服务器操作系统是 openSUSE Tumbleweed 32 位，其 DNS 服务器已由 YAST2 配置。看一下/etc/named.conf表示named工作目录：

    options {

        # The directory statement defines the name server's working directory

        directory "/var/lib/named";

    还/etc/named.conf指示相对于工作目录的区域文件：

    zone "example.com" in {
        allow-transfer { any; };
        file "master/example.comXX";
        type master;
};

    前

    /var/lib/named/master/example.comXX内容是：

    $TTL 2d
@               IN SOA          localhost.      root.localhost. (
                                2021062000      ; serial
                                3h              ; refresh
                                1h              ; retry
                                1w              ; expiry
                                1d )            ; minimum

example.com.  IN NS           ns.example.com.
example.com   IN A            4.21.3.12
ns              IN A            4.21.3.12

    后

    /var/lib/named/master/example.comXX根据此处的示例修改内容：

    https://ubuntu.com/server/docs/service-domain-name-service-dns

    修改后的新/var/lib/named/master/example.comXX内容是：

    $TTL 2d
@               IN SOA          example.com.  root.example.com. (
                                2021062000      ; serial
                                3h              ; refresh
                                1h              ; retry
                                1w              ; expiry
                                1d )            ; minimum

@       IN NS           ns.example.com.
@       IN A            4.21.3.12
@       IN AAAA         ::1
ns      IN A            4.21.3.12

    经过/var/lib/named/master/example.comXX上面的修改，现在可以通过地址浏览网站了。
