리눅스에 dnf 명령어로 jenkins를 설치해보고자 한다.
리눅스 젠킨스 설치순서는 아래와 같이 진행하면 무탈하다
- Java 11 이상 설치
- Jenkins GPG Key 설치
rpm --import https://pkg.jenkins.io/redhat-stable/jenkins.io-2023.key - Jenkins repo 등록
dnf config-manager --add-repo https://pkg.jenkins.io/redhat-stable/jenkins.repo - dnf install jenkins
- systemctl start jenkins
먼저 java가 설치되어 있어야 하므로 java를 먼저 설치해준다.
11 버전 이상을 설치해줘야 된다. 8버전 설치하면 jenkins 구동 안됨.
[root@cb6f01f0a4ec /]# dnf install java-11-openjdk.x86_64

이제 젠킨스를 설치하면 되는데
설치전에 사전 작업들이 필요하다. (jenkins repo 등록하고 GPG key를 설치해야 한다.)
일단 사전 작업을 하지 않았을때 어떤 메세지가 나오는지 봐보자.
사전작업 없이 jenkins install 명령어 입력했을때,
아래와 같이 찾을 수 없다고 뜸.
[root@cb6f01f0a4ec ~]# dnf install jenkins
Last metadata expiration check: 0:02:37 ago on Mon Aug 28 23:42:48 2023.
No match for argument: jenkins
Error: Unable to find a match: jenkins
jenkins repo 를 등록해줘야 하는데
아래와 같은 에러가 날 수도 있다.
[root@cb6f01f0a4ec ~]# dnf config-manager --add-repo https://pkg.jenkins.io/redhat-stable/jenkins.repo
No such command: config-manager. Please use /usr/bin/dnf --help
It could be a DNF plugin command, try: "dnf install 'dnf-command(config-manager)'"
dnf-command(config-manager) 플러그인을 설치하라고 그런다.
설치해주자
[root@cb6f01f0a4ec ~]# dnf install 'dnf-command(config-manager)'

Installing:

그런 다음 다시 jenkins repo 를 등록해주면 잘 등록되는 것을 확인 할 수 있다.
[root@cb6f01f0a4ec ~]# dnf config-manager --add-repo https://pkg.jenkins.io/redhat-stable/jenkins.repo
Adding repo from: https://pkg.jenkins.io/redhat-stable/jenkins.repo
GPG key 를 설치하지 않고 jenkins를 install 하면 아래와 같이 메세지가 뜬다.
[root@cb6f01f0a4ec ~]# dnf install jenkins

GPG key 를 설치해주고 패키지를 clean 한뒤 다시 젠킨스를 설치해주자

설정 변경은
/usr/lib/systemd/system/jenkins.service 파일을 vi로 열어 수정할 것!
젠킨스를 리눅스에서 버전 업데이트 하시는 방법은 아래와 같습니다.
[Jenkins] 젠킨스 버전 업데이트하기 (feat.rockylinux)
[Jenkins] 젠킨스 버전 업데이트하기 (feat.rockylinux)
젠킨스 버전이 수시로 나오므로 버전 차이가 너무 나지 않게 적당한 수준에서 업데이트 해주는 것이 좋겠다. 젠킨스가 설치되지 않았다면 아래 설치 포스트를 참고하여 설치하시길 바랍니다. [J
