我已尝试配置我的 BIND-DNS 服务器,以便它将响应对我的域 prognoza.cu.cc 的子域 mail.prognoza.cu.cc 发出的 DNS 请求。
我定义了一个 mail.prognoza.cu.cc 的 NS 记录,以服务器 IP 作为内容。
我还配置了 BIND,如下所示:
session-keyfile "/run/named/session.key";
};
logging {
channel default_debug {
file "data/named.run";
severity dynamic;
};
};
zone "." IN {
type hint;
file "named.ca";
};
zone "mail.prognoza.cu.cc" IN {
type master;
file "/var/named/prognoza.cu.cc.zone";
allow-update { none; };
};
include "/etc/named.rfc1912.zones";
include "/etc/named.root.key";
这是 prognoza.cu.cc.zone:
@ IN SOA ns1.prognoza.cu.cc. hostmaster.prognoza.cu.cc. (
2013042201 ;Serial
3600 ;Refresh
1800 ;Retry
604800 ;Expire
3600 ;Minimum TTL
)
; Specify our two nameservers
IN NS localhost.
; Resolve nameserver hostnames to IP, replace with your two droplet IP addresses.
ns1 IN A 31.220.108.9
; Define hostname -> IP pairs which you wish to resolve
@ IN A 31.220.108.9
www IN A 31.220.108.9
由于某种原因,它不起作用。每当我 nslookup mail.prognoza.cu.cc 时,它都会失败,这是在服务器内挖掘的结果:
dig mail.prognoza.cu.cc ANy
; <<>> DiG 9.9.4-RedHat-9.9.4-38.el7_3.1 <<>> mail.prognoza.cu.cc ANy

由于某种原因,没有找到记录。
有人能找出问题所在吗?
