[리눅스] RHCSA 9(3), Repository 등록 (feat.gpgkey, gpgcheck)

 

문제3. 기본 저장 공간(Repository)을 아래 지시 사항에 맞게 설정하라.

 

* 아래는 제가 임의로 작성한 예시입니다.실전에서는 시험장 환경에 맞는 저장소 정보가 주어집니다.

실습용 저장소 1: https://mirror.navercorp.com/rocky/9.3/AppStream/x86_64/os/
실습용 저장소 2: https://mirror.navercorp.com/rocky/9.3/BaseOS/x86_64/os/

 

 

Repo 생성(등록)

[root@servera ~]# dnf config-manager --add-repo http://mirror.navercorp.com/rocky/9.3/AppStream/x86_64/os/
Adding repo from: http://mirror.navercorp.com/rocky/9.3/AppStream/x86_64/os/

[root@servera ~]# dnf config-manager --add-repo http://mirror.navercorp.com/rocky/9.3/BaseOS/x86_64/os
Adding repo from: http://mirror.navercorp.com/rocky/9.3/BaseOS/x86_64/os

 

 

세부 설정값 확인

[servera]# cd /etc/yum.repos.d/
[servera]# ls
mirror.navercorp.com_rocky_9.3_AppStream_x86_64_os_.repo
mirror.navercorp.com_rocky_9.3_BaseOS_x86_64_os.repo

[servera]# cat mirror.navercorp.com_rocky_9.3_AppStream_x86_64_os_.repo
[mirror.navercorp.com_rocky_9.3_AppStream_x86_64_os_]
name=created by dnf config-manager from http://mirror.navercorp.com/rocky/9.3/AppStream/x86_64/os/
baseurl=http://mirror.navercorp.com/rocky/9.3/AppStream/x86_64/os/
enabled=1
gpgcheck=0

[servera]# cat mirror.navercorp.com_rocky_9.3_BaseOS_x86_64_os.repo
[mirror.navercorp.com_rocky_9.3_BaseOS_x86_64_os]
name=created by dnf config-manager from http://mirror.navercorp.com/rocky/9.3/BaseOS/x86_64/os
baseurl=http://mirror.navercorp.com/rocky/9.3/BaseOS/x86_64/os
enabled=1
gpgcheck=0

 

 

만약 문제에서 인증키(gpgkey)를 등록하고 활성화하라고 한다면?

아래처럼 생성된 repo 파일 수정이 필요하다.

[servera]# cat mirror.navercorp.com_rocky_9.3_AppStream_x86_64_os_.repo
[mirror.navercorp.com_rocky_9.3_AppStream_x86_64_os_]
name=created by dnf config-manager from http://mirror.navercorp.com/rocky/9.3/AppStream/x86_64/os/
baseurl=http://mirror.navercorp.com/rocky/9.3/AppStream/x86_64/os/
enabled=1
gpgkey=1.1.1.1  	// 임의로 설정한 값이며, 시험장에서는 다른 gpgkey값이 주어질 것이다.
gpgcheck=1  		// 1=enable, 0=disable

[servera]# cat mirror.navercorp.com_rocky_9.3_BaseOS_x86_64_os.repo
[mirror.navercorp.com_rocky_9.3_BaseOS_x86_64_os]
name=created by dnf config-manager from http://mirror.navercorp.com/rocky/9.3/BaseOS/x86_64/os
baseurl=http://mirror.navercorp.com/rocky/9.3/BaseOS/x86_64/os
enabled=1
gpgkey=1.1.1.1
gpgcheck=1

 

 

그리고 dnf config-manager --add-repo로 등록 시 입력한 URL이 repo 파일 이름으로 생성된다.

아래처럼 간단하게 변경해준다.

[servera]# cd /etc/yum.repos.d
[servera]# ls
mirror.navercorp.com_rocky_9.3_AppStream_x86_64_os_.repo AppStream.repo
mirror.navercorp.com_rocky_9.3_BaseOS_x86_64_os_.repo BaseOS.repo

[servera]# mv mirror.navercorp.com_rocky_9.3_AppStream_x86_64_os_.repo AppStream.repo
[servera]# mv mirror.navercorp.com_rocky_9.3_BaseOS_x86_64_os_.repo BaseOS.repo

[servera]# ls
AppStream.repo
BaseOS.repo

 

 

마지막으로 기존 저장소 삭제 및 최신 저장소 목록 정상 반영되었는지 확인

[servera]# dnf clean all  // 기존 저장소 정보 삭제
25 files removed

[servera]# dnf repolist  // 현재 저장소 목록 확인
repo id                                             repo name
