Centos 7 바인드는 아무것도 반환하지 않습니다.

DNS 서버를 만들려고 시도했지만 dig 명령을 수행하면 서버가 아무것도 반환하지 않습니다. 저는 이전 경험이 없으며 이 튜토리얼만 따르고 있습니다.http://www.itzgeek.com/how-tos/linux/centos-how-tos/configure-dns-bind-server-on-centos-7-rhel-7.html.

업데이트:/etc/resolv.conf네트워크 관리자가 다시 시작될 때마다 덮어쓰여지 는 문제인 것 같습니다 . 나중에 if-cfg 파일을 얻을 수 있게 되면 이를 다시 업데이트하겠습니다.

귀하의 영역을 테스트 상자에 로드했는데 제게는 효과가 있었습니다.

[test@server ~]# dig www.dynavio.coop

다른 서브넷 등에 대해 구성되었으므로 내 주소를 사용해야 했으며 NSDNS 키가 설정되어 있지 않아 테스트할 수 없습니다.

확인해야 할 몇 가지 사항;

무엇을 설정했습니까? /etc/resolv.conf다음과 같은 줄이 있어야 합니다. nameserver 127.0.0.1귀하의 상자가 자체적으로 NS 조회를 요청하도록 귀하의 컴퓨터가 다른 DNS 서버를 사용하도록 구성된 것 같습니다.

상자의 IP 주소는 무엇입니까? 원래 질문에 primary역방향 주소 .8와 역방향 주소가 포함되어 오류가 있었습니다..103
