為什麼使用我的域地址無法訪問我的網站？

我使用以下文件創建了一個 DNS 伺服器，將我的域地址映射sudia.com到我的 VPS 伺服器，但它不起作用，我無法使用我的域地址訪問我的伺服器。還必須說有一個 NginX 正在執行ttp://136.243.197.164:3200。

/etc/named.conf：目錄“/var/named”；轉儲文件“/var/named/data/cache_dump.db”；統計文件“/var/named/data/named_stats.txt”；memstatistics-file “/var/named/data/named_mem_stats.txt”; secroots-file “/var/named/data/named.secroots”; 遞歸文件“/var/named/data/named.recursing”；允許查詢{本地主機；136.243.197.164;};

        - If your recursive DNS server has a public IP address, you MUST enable access

;PTR Record IP address to HostName
164      IN  PTR     www.sudia.com

編輯：這是結果host www.sudia.com：

www.sudia.com has address 136.243.197.164

但是host sudia.com（沒有www）不起作用！

您的區域文件沒有 www.sudia.com 的正確記錄。將此添加到您的區域。例如，通過更改此文件/var/named/fwd.sudia.com.db或通過 nsupdate：

方法一（更新文件/var/named/fwd.sudia.com.db，別忘了更新串口）：

@    IN    A    136.243.197.164

方法 2 (nsupdate) 例如：

[root@ns1 ~]# nsupdate -k /etc/rndc.key
> server localhost
> zone sudia.com.
> update add sudia.com. 3600 IN A 136.243.197.164
> send
[root@ns1 ~]#

然後您的名稱伺服器可以將根域（例如 sudia.com）解析為正確的 IP 地址。
