RHEL 8에 이더넷 인터페이스가 없습니다.

tag-icon • tag-icon network-interface
RHEL 8에 이더넷 인터페이스가 없습니다.

이전에는 Network-scripts 디렉토리에 아무것도 없었지만 ISO에서 네트워크 스크립트를 설치한 후 거의 모든 파일이 나타 났지만 RHEL 8 VM에는 네트워크 인터페이스가 없습니다.

rhel8에 네트워크 인터페이스가 없습니다.

nmtui를 사용하여 이더넷 장치를 추가하려고 시도했는데 파일이 생성되었지만 네트워크 서비스를 다시 시작한 후 "장치를 찾을 수 없습니다"라는 오류가 발생했습니다.

Thanks for your reply A B,
There is no change in Hardware or Accidental damage. i was able to use same VM 3-4 months ago. suddenly network was not working. i tried installing new VM with RHEL8, still same issue.

답변1

이전 RedHat 인스턴스를 RHEL 7로 업그레이드한 후 이 문제(또는 유사한 문제)가 발생했습니다. 일부 네트워크 관련 서비스가 시작 시 실패했습니다. 시간이 초과되어 시스템 부팅이 차단되지 않지만 네트워크에 연결할 수 없습니다.

편집: 이전 솔루션이 불완전하여 다음에 적용해야 할 때 실패했습니다. 이제 이것이 완전한 솔루션인 것 같습니다.

나는 Red Hat에서 나에게 도움이 되는 문제와 해결책을 설명하는 다음 기사를 찾았습니다.https://access.redhat.com/solutions/2592561 이 문서에서는 내 상황을 매우 정확하게 설명합니다. 이 문제를 방지하는 "정오표"가 포함되지 않은 DVD ISO 이미지를 사용하여 VMWare 게스트를 6에서 7로 업그레이드하는 것입니다.

결국 다음 명령을 실행했습니다.

nmcli connection modify 'System eth0' connection.interface-name ens192
nmcli connection modify 'System eth0' connection.id ens192
nmcli connection up ens192

다시 시작하면 시스템이 정상으로 돌아옵니다!
