sudo yum -y update;
sudo wget -O /etc/yum.repos.d/jenkins.repo \
    https://pkg.jenkins.io/redhat-stable/jenkins.repo;
sudo rpm --import https://pkg.jenkins.io/redhat-stable/jenkins.io.key;
sudo yum upgrade -y;
sudo amazon-linux-extras install epel -y;

sudo amazon-linux-extras install java-openjdk11 -y

sudo systemctl daemon-reload;
sudo systemctl start jenkins;

sudo systemctl status jenkins;

sudo yum install -y docker;
sudo systemctl enable docker;
sudo systemctl start docker;
sudo usermod -aG docker jenkins;

- Amazon 리눅스의 경우 sudo amazon-linux-extras install epel -y; 명령어 실행 필요

- docker 설치 부분은 docker를 이용하여 jenkins를 설치하기 위한 사전 작업 

 

Jenkins 설치시 Java 11버전이 아닌 Java 1.8버전으로 설치했을 경우 서비스 확인시 아래와 같은 에러가 나타날 수 있다.

# journalctl -xe -u jenkins

→ Linux 서비스 매니저인 systemd는 로그 데이터를 journal이라는 바이너리 형식으로 저장한다. journalctl은 journal에서 로그를 검색하고 조회할 수 있는 systemd 유틸리티 중 하나이다.

jenkins: invalid Java version: openjdk version "1.8.0_342" 

위 에러와 같이 22년 이후 jenkins 버전에서는 Java 11버전 필요하며 Java 1.8버전을 사용한다면 Java 11버전 설치가 필요

https://www.jenkins.io/blog/2022/06/28/require-java-11/

Jenkins requires Java 11 or newer

Java 11버전 설치 방법

# Java 11버전 다운
sudo amazon-linux-extras install -y java-openjdk11

# 패키지 관리자에 corrtto rpm 레포지토리 추가
sudo rpm --import https://yum.corretto.aws/corretto.key
sudo curl -L -o /etc/yum.repos.d/corretto.repo https://yum.corretto.aws/corretto.repo

# java 11 설치
sudo yum install -y java-11-amazon-corretto-devel

# 설치가능 패키지 확인
yum list java*jdk-devel

# 11버전 설치
yum install -y java-11-openjdk-devel.x86_64

# 기존 Java 1.8버전이 설치되어 있기 때문에 Java 11버전으로 변경 
 update-alternatives --config java

There are 3 programs which provide 'java'.

  Selection    Command
-----------------------------------------------
   1           java-1.8.0-openjdk.x86_64 (/usr/lib/jvm/java-1.8.0-openjdk-1.8.0.342.b07-1.amzn2.0.1.x86_64/jre/bin/java)
   2           java-11-openjdk.x86_64 (/usr/lib/jvm/java-11-openjdk-11.0.16.0.8-1.amzn2.0.1.x86_64/bin/java)
*+ 3           /usr/lib/jvm/java-11-amazon-corretto/bin/java
