답변1
Bind가 시작되지 않는 이유는 시작 전 검사에서 반환된 오류 조건 때문입니다 /usr/sbin/named-checkconf -z /etc/named.conf. 문제를 해결해야 합니다.
~영역 파일 끝에 있는 외로운 물결표 문자는 유효한 리소스 레코드가 아니므로 제거해야 합니다.
영역 내 네임서버를 선언합니다.
IN NS benu123.com
A 이름 서버에 대한 레코드를 생성하지 않고 . 그것은 명백히 잘못된 것입니다. 또한 a로 끝나지 않는 리소스 레코드는 .DNS 약칭으로 처리되고 $ORIGIN(영역 이름)이 추가되므로 현재 가지고 있는 내용은 다음과 기능적으로 동일합니다.
IN NS benu123.com.benu123.com.
대신 다음과 같은 것을 원해야 할 것입니다.
$ORIGIN benu123.com.
$TTL 86400
@ IN SOA benu123.com. root.benu123.com(
2014030401 ; serial
3600 ; refresh
1800 ; retry
604800 ; expire
86400 ; minimum
)
IN NS benu123.com.
@ IN A 192.168.1.1 ; replace this with the ip-address of your name-server
localhost IN A 127.0.0.1
localhost IN AAAA ::1
benu55 IN AAAA 2001::2222
benu89 IN AAAA 2002::2222
여기서는 또 다른 DNS 속기 트릭을 사용했는데 @이는 $ORIGIN 또는 도메인 이름 benu123.com과 동일합니다.
답변2
최소한 NS 항목에는 A 또는 AAAA 레코드가 필요합니다(네임서버가 benu123.com.benu123.com으로 호출되지 않는 한 끝에 점이 있을 가능성이 높습니다).
