答案1
您的前向区域文件中存在错误,请参见以下行中的错误:
zone example.com/IN: NS 'dsn1.example.com' has no address records (A or AAAA)
您指定您的NS 记录但dns1.example.com.
一个记录是dns.example.com
正确的区域文件示例:
$TTL 86400
@ IN SOA dns1.example.com. hostmaster.example.com. (
2001062501
21600
3600
604800
86400
)
; NS RECORD
@ IN NS dns1
; MX RECORD
@ IN MX 10 mail
; A RECORDS
@ IN A 192.168.0.104
dns1 IN A 192.168.0.104
mail IN A 192.168.0.104
machine6 IN A 192.168.0.104
ftp IN A 192.168.0.104
; CNAME RECORDS
www IN CNAME example.com.
这MX 记录必须指向一个一个记录,不是CNAME 记录。
此示例还将example.com
在第一个中定义为有效域名一个记录。
machine6
也ftp
可以是CNAME 记录。
