我使用 bind9 创建了 dns 服务器，服务器内部一切正常。我可以 ping 我的域，也可以挖掘它。但在我的 vps 之外，域名称没有名称服务器。
我用这个命令
dig @89.42.210.210 fdoc.ir
服务器内部 dig 命令输出

nginx 配置
# You should look at the following URL's in order to grasp a solid understanding
# of Nginx configuration files in order to fully unleash the power of Nginx.
# http://wiki.nginx.org/Pitfalls
# http://wiki.nginx.org/QuickStart
# http://wiki.nginx.org/Configuration
#
# Generally, you will want to move this file somewhere, and start with a clean
# file but keep this around for reference. Or just disable in sites-enabled.
#
# Please see /usr/share/doc/nginx-doc/examples/ for more detailed examples.
##
# Default server configuration
#

listen 80;
listen [::]:80;
# SSL configuration
#
# listen 443 ssl default_server;
# listen [::]:443 ssl default_server;
#
# Note: You should disable gzip for SSL traffic.
# See: https://bugs.debian.org/773332

答案1
可能有两个罪犯。
首先检查绑定服务器是否正在监听外部 IP 或任何 IP（0.0.0.0），/etc/bind/named.conf.options例如
listen-on port 53 { any; }
第二个也是更可能的事情是检查你的 iptables 规则，以便它们允许 UDP 流量进入端口 53。如果你运行iptables -L -n它，应该会有类似
Chain INPUT (policy DROP)
ACCEPT udp -- 0.0.0.0/0 0.0.0.0/0 udp dpt:53
如果没有，您可以通过以 root 身份执行来临时添加这样的规则
iptables -I INPUT -p udp --dport 53 -j ACCEPT
当然，您的服务器和互联网之间的任何其他防火墙也可能阻止流量。

谢谢你的帮助，但问题解决了，这是问题
/etc/named.conf.local
//include "/etc/bind/zones.rfc1918";
并且只需取消注释上面的行，一切就可以正常工作。
