"HP Proliant DL380p Gen8"에 CentOS의 새 복사본을 설치했는데 이더넷 인터페이스에서 인터페이스가 제대로 작동하거나 완전히 멈추는 이상하고 고르지 못한 연결 문제가 발생했습니다.
다음은 일부 명령의 출력입니다.

답변1
Centos는 설치 중에 수동으로 활성화하지 않는 한 일반적으로 네트워킹을 비활성화합니다. 물리적 네트워크 링크가 제대로 연결되어 있으면 ip link명령을 사용하여 링크를 확인할 수 있습니다. 다음 경로에 있는 각 인터페이스 구성에서 ONBOOT=no행을 설정할 수 있습니다.ONBOOT=yes
/etc/sysconfig/network-scripts/ifcfg-xxxx
nmcli c최신 centos 7.x인 경우 다음 명령을 입력하여 더 많은 정보를 얻을 수 있습니다.
답변2
인터페이스 파일 이름을 바꿉니다.
mv ifcfg-en01 ifcfg-eno1
