在正向和反向运行named-checkzone时没有当前所有者名称错误

Question

我正在尝试在 Digital Ocean 学习 dns 并在 centos 7 上绑定。当我运行时，named-checkzone我遇到同样的错误。当我更改空白区域时，我会停止该错误，只是将其替换为 0 SOA 并且没有 NS 错误。

sudo named-checkzone example.com /etc/named/zones/example.com.zone
/etc/named/zones/example.com.zone:1: no current owner name
/etc/named/zones/example.com.zone:2: no current owner name
/etc/named/zones/example.com.zone:3: no current owner name
/etc/named/zones/example.com.zone:16: no current owner name
/etc/named/zones/example.com.zone:17: no current owner name
/etc/named/zones/example.com.zone:18: no current owner name
/etc/named/zones/example.com.zone:19: no current owner name
/etc/named/zones/example.com.zone:24: no current owner name
/etc/named/zones/example.com.zone:25: no current owner name
/etc/named/zones/example.com.zone:26: no current owner name
/etc/named/zones/example.com.zone:27: no current owner name
/etc/named/zones/example.com.zone:28: no current owner name
/etc/named/zones/example.com.zone:29: no current owner name  

$ORIGIN example.com.

Answer 1

正如 Julie Pelletier 已经评论的那样，删除区域记录中的前导空格，因为它们在绑定区域文件中具有特殊含义。

通过以空格（既不是主机名、区域名称也不是区域起源的@简写）开始一行，该行将成为其上方记录的延续。

$ORIGIN neilanuskiewicz.com.
$TTL 14400
 @    IN    SOA    ns1.neilanuskiewicz.com.   ...

这使得带有 SOA 记录的行成为其上方不存在的记录的延续（在这方面变量不计入），因此你失败了；它上面有资源记录，没有所有者可以应用该延续记录。

$ORIGIN neilanuskiewicz.com.
$TTL 14400
@    IN    SOA    ns1.neilanuskiewicz.com.   ...

您可以有意使用以空格开头的行：

@                    IN  A     192.0.2.1       ; IPv4 address for the bare domain using the @ short hand
neilanuskiewicz.com. IN  AAAA  2001:db8:10::1  ; IPv6 address for the bare domain
www                  IN  A     192.0.2.1            
                     IN  AAAA  2001:db8:10::1  ; IPv6 address for www using DNS shorthand by starting this line with a space
