Red Hat 8.6에 OpenJDK 21 오프라인 설치 상세 가이드
이 가이드는 인터넷에 연결되지 않은 오프라인 Red Hat Enterprise Linux (RHEL) 8.6 환경에서 OpenJDK21U-jdk_x64_linux_hotspot_21.0.8_9.tar.gz 파일을 사용하여 OpenJDK 21을 설치하는 과정을 상세하게 설명합니다.
1. 사전 준비
OpenJDK 아카이브 다운로드: 인터넷이 연결된 다른 컴퓨터에서 Adoptium (구 AdoptOpenJDK) 또는 Oracle의 웹사이트를 통해 OpenJDK21U-jdk_x64_linux_hotspot_21.0.8_9.tar.gz 파일을 다운로드합니다.
2. 파일 전송: 다운로드한 파일을 USB 드라이브, 외장 하드 드라이브 또는 내부 네트워크를 통해 오프라인 RHEL 8.6 서버의 특정 디렉토리(예: /tmp 또는 사용자의 홈 디렉토리)로 복사합니다.
curl -L -o OpenJDK21U-jdk_x64_linux_hotspot_21.0.8_9.tar.gz https://mirror.math.princeton.edu/pub/redcorelinux/amd64/distfiles/OpenJDK21U-jdk_x64_linux_hotspot_21.0.8_9.tar.gz
1단계: 압축 해제
먼저, 서버에 전송된 .tar.gz 파일의 압축을 풀어야 합니다. 일반적으로 Java와 같은 소프트웨어는 /opt 또는 /usr/local 디렉토리에 설치하는 것이 좋습니다.
설치 디렉토리 생성 (선택 사항): /opt 디렉토리 아래에 jdk를 관리할 폴더를 생성합니다.
sudo mkdir -p /opt/jdk압축 해제: /tmp 디렉토리에 파일을 옮겼다고 가정하고, 아래 명령어를 사용하여 /opt/jdk 디렉토리에 압축을 해제합니다.
sudo tar -zxvf /tmp/OpenJDK21U-jdk_x64_linux_hotspot_21.0.8_9.tar.gz -C /opt/jdk-
압축이 풀리면 /opt/jdk 아래에 jdk-21.0.8+9 와 같은 디렉토리가 생성됩니다.

2단계: 환경 변수 설정
시스템의 모든 사용자가 Java를 사용할 수 있도록 전역 환경 변수를 설정합니다.
/etc/profile.d/ 디렉토리에 스크립트 파일 생성:
sudo vi /etc/profile.d/openjdk21.sh환경 변수 내용 추가: vi 편집기에서 i를 눌러 입력 모드로 전환한 후, 다음 내용을 붙여넣습니다. 압축 해제 후 생성된 디렉토리 이름(jdk-21.0.8+9)을 정확하게 입력해야 합니다.
#!/bin/bash
export JAVA_HOME=/opt/jdk/jdk-21.0.8+9
export PATH=$JAVA_HOME/bin:$PATH
export CLASSPATH=$JAVA_HOME/lib저장 및 종료: Esc 키를 누른 후 :wq를 입력하여 저장하고 편집기를 종료합니다.
스크립트에 실행 권한 부여:
sudo chmod +x /etc/profile.d/openjdk21.sh환경 변수 즉시 적용: 시스템을 재부팅하거나 아래 명령어를 실행하여 현재 세션에 바로 적용할 수 있습니다.
source /etc/profile.d/openjdk21.sh================================
3단계: alternatives 시스템에 등록
alternatives는 시스템에 여러 버전의 Java가 설치되어 있을 때 기본 버전을 쉽게 전환할 수 있도록 도와주는 도구입니다.
우분투 버전 등록
https://memories.tistory.com/59
java 등록:
sudo alternatives --install /usr/bin/java java /opt/jdk/jdk-21.0.8+9/bin/java 21javac 등록:
sudo alternatives --install /usr/bin/javac javac /opt/jdk/jdk-21.0.8+9/bin/javac 21- --install 옵션은 (링크 위치) (이름) (실제 파일 위치) (우선순위) 순서로 지정합니다. 우선순위 번호(여기서는 21)가 높을수록 기본값으로 설정될 확률이 높습니다.
기본 Java 버전 설정: 만약 시스템에 다른 버전의 Java가 설치되어 있다면, 아래 명령어를 통해 기본 버전을 선택할 수 있습니다.
sudo alternatives --config java명령어를 실행하면 설치된 Java 버전 목록이 나타납니다. OpenJDK 21에 해당하는 번호를 입력하고 Enter를 누릅니다. javac도 동일하게 설정할 수 있습니다.
=============================================
- 설치 확인
모든 설정이 완료된 후, 터미널에서 다음 명령어를 실행하여 설치가 성공적으로 이루어졌는지 확인합니다.
Java 버전 확인:
java -version
openjdk version "21.0.8" 2025-07-15
OpenJDK Runtime Environment Temurin-21.0.8+9 (build 21.0.8+9)
OpenJDK 64-Bit Server VM Temurin-21.0.8+9 (build 21.0.8+9, mixed mode)
컴파일러 버전 확인:
javac -version
javac 21.0.8환경 변수 확인:
echo $JAVA_HOME예상 출력:
/opt/jdk/jdk-21.0.8+9위와 같이 버전과 환경 변수가 올바르게 출력된다면, Red Hat 8.6 오프라인 환경에 OpenJDK 21 설치가 성공적으로 완료된 것입니다
- 참고사항
Java JDK 21을 tar 형태로 설치할 때 권장되는 위치는 운영체제에 따라 다르지만, 리눅스나 macOS에서는 일반적으로 /opt/java, /usr/local/java와 같은 디렉토리에 설치하고, 경로를 ~/.bashrc 또는 ~/.zshrc에 JAVA_HOME 환경 변수를 설정하여 사용합니다. Windows에서는 .tar.gz 파일을 수동으로 압축 해제하여 C:\Program Files\Java 폴더 아래에 설치하는 것이 일반적입니다.
리눅스/macOS에서 설치 시 권장 위치
디렉토리 생성: JDK 압축 파일을 풀 디렉토리를 생성합니다.
/opt/java 또는 /usr/local/java 와 같은 디렉토리에 설치합니다.
sudo mkdir -p /opt/java (예시)
압축 파일 해제: 다운로드한 jdk-21.tar.gz 파일을 해당 디렉토리로 이동시켜 압축을 해제합니다.
sudo tar -zxvf jdk-21.tar.gz -C /opt/java (예시)
경로 설정: JAVA_HOME 환경 변수를 설정하여 JDK의 경로를 지정합니다.
~/.bashrc 또는 ~/.zshrc 파일을 열어 다음 내용을 추가합니다.
export JAVA_HOME=/opt/java/jdk-21 (설치 경로에 맞게 수정)
export PATH=$JAVA_HOME/bin:$PATH
파일을 저장하고 source ~/.bashrc 또는 source ~/.zshrc 명령어로 적용합니다.
Windows에서 설치 시 권장 위치
JDK 다운로드: Oracle 공식 홈페이지나 Microsoft Learn에서 운영체제에 맞는 jdk-21.tar.gz 파일을 다운로드합니다.
압축 파일 해제: 다운로드한 .tar.gz 파일을 원하는 위치에 압축 해제합니다.
일반적으로 C:\Program Files\Java 폴더 아래에 jdk-21과 같은 이름으로 압축을 풉니다.
JAVA_HOME 환경 변수 설정:
시스템 설정에서 "고급 시스템 설정 보기"를 선택합니다.
환경 변수 버튼을 클릭하여 JAVA_HOME 변수를 생성하고, 변수 값으로 설치된 JDK 경로를 입력합니다 (예: C:\Program Files\Java\jdk-21).
Path 환경 변수에도 %JAVA_HOME%\bin을 추가합니다.
주의사항
tar.gz 파일은 리눅스/macOS에서 주로 사용되며, Windows 환경에서는 .zip 또는 .exe 설치 파일을 사용하는 것이 더 일반적입니다.
설치 후에는 JAVA_HOME 환경 변수를 올바르게 설정하여 IDE나 다른 개발 도구에서 JDK를 인식할 수 있도록 해야 합니다.

t Enterprise Linux 8.6 오프라인 환경 Docker 설치 상세 가이드
Red Hat Enterprise Linux (RHEL) 8.6 환경에서는 기본적으로 Docker 대신 Podman을 컨테이너 엔진으로 사용합니다. 하지만 필요에 따라 Docker-CE (Community Edition)를 수동으로 설치할 수 있습니다. 인터넷이 차단된 오프라인 환경에 Docker를 설치하려면, 인터넷이 연결된 다른 머신에서 필요한 모든 RPM 패키지와 의존성 파일을 다운로드하여 대상 서버로 옮긴 후 설치를 진행해야 합니다.
이 가이드에서는 온라인 머신에서 필요 파일을 준비하는 과정부터 오프라인 RHEL 8.6 서버에 Docker를 성공적으로 설치하고 설정하는 단계까지 상세하게 안내합니다.
1단계: 온라인 머신에서 Docker 패키지 및 의존성 다운로드
먼저 인터넷에 연결된 동일한 아키텍처(x86_64)의 RHEL 8.6 또는 CentOS 8 환경의 머신이 필요합니다. 이 머신에서 Docker 설치에 필요한 모든 파일을 다운로드합니다.
- Docker 리포지토리 설정:
온라인 머신에 Docker CE의 공식 CentOS 리포지토리를 추가합니다. RHEL용 Docker 패키지는 CentOS 리포지토리를 통해 안정적으로 받을 수 있습니다.

sudo yum install -y yum-utils
sudo yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo- 필요 패키지 및 모든 의존성 다운로드:
yumdownloader 유틸리티를 사용하여 Docker CE 관련 패키지와 그에 필요한 모든 의존성 패키지를 지정된 디렉토리(~/docker-offline-packages)에 다운로드합니다.
# 다운로드할 디렉토리 생성
mkdir ~/docker-offline-packages
# yumdownloader를 사용하여 Docker CE 최신 버전과 모든 의존성 패키지 다운로드
## sudo yumdownloader --resolve --destdir=~/docker-offline-packages docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin--resolve 옵션은 지정된 패키지뿐만 아니라 관련된 모든 의존성 패키지까지 함께 다운로드하는 중요한 역할을 합니다.
- 다운로드된 파일 압축:
다운로드한 모든 RPM 파일들을 하나의 압축 파일로 만듭니다. 이렇게 하면 오프라인 서버로 파일을 옮기기가 수월해집니다.
tar -czvf docker-offline-packages.tar.gz -C ~/docker-offline-packages .이제 docker-offline-packages.tar.gz 파일이 생성되었습니다. 이 파일을 USB 드라이브나 SCP(Secure Copy) 등을 사용하여 오프라인 RHEL 8.6 서버로 복사합니다.
2단계: 오프라인 RHEL 8.6 서버에 Docker 설치
온라인 머신에서 준비한 압축 파일을 오프라인 서버의 원하는 위치(예: /tmp)로 옮긴 후 다음 단계를 진행합니다.
- 압축 해제:
서버로 옮긴 압축 파일을 풀어줍니다.
# 파일을 저장할 디렉토리 생성
mkdir /tmp/docker-install# 압축 해제
tar -xzvf docker-offline-packages.tar.gz -C /tmp/docker-install- 기존 컨테이너 런타임 충돌 방지 (필요시):
RHEL 8.6에는 기본적으로 Podman이 설치되어 있을 수 있으며, 일부 패키지가 Docker와 충돌을 일으킬 수 있습니다. podman과 buildah 패키지를 삭제하여 잠재적인 충돌을 방지하는 것이 좋습니다.

Active: active (running) 메시지가 표시되면 정상적으로 실행 중인 것입니다.
- 'hello-world' 이미지로 테스트 실행:
오프라인 환경이므로 Docker Hub에서 이미지를 받아올 수 없습니다. 하지만 설치가 제대로 되었는지 확인하기 위해 docker run 명령어를 실행해 볼 수 있습니다. (오프라인이므로 이미지가 없다는 오류가 뜨는 것이 정상입니다.)
docker run hello-world위 명령 실행 시 "Unable to find image 'hello-world:latest' locally" 와 같은 메시지가 출력되면 Docker 클라이언트가 데몬과 정상적으로 통신하고 있다는 의미이므로 설치는 성공한 것입니다.
- 일반 사용자를 docker 그룹에 추가 (권장):
매번 sudo를 입력하지 않고 docker 명령어를 사용하려면 현재 사용자를 docker 그룹에 추가해야 합니다.
# 현재 사용자를 docker 그룹에 추가
sudo usermod -aG docker $USER
# 변경 사항을 적용하기 위해 재로그인하거나 다음 명령 실행
newgrp docker

이제 sudo 없이 docker ps, docker images 등의 명령어를 사용할 수 있습니다.
이것으로 오프라인 RHEL 8.6 환경에 Docker 설치가 완료되었습니다. 필요한 Docker 이미지는 온라인 환경에서 docker save 명령어로 tar 파일로 추출한 뒤, 오프라인 서버에서 docker load 명령어로 로드하여 사용해야 합니다.

Docker Compose (Standalone) 다운로드
Docker Compose는 RPM 패키지가 아닌 단일 바이너리 파일로 제공됩니다. GitHub 릴리즈 페이지에서 직접 다운로드합니다.
# 최신 버전을 확인하고 다운로드 (예: v2.27.0)
# 아래 URL에서 버전을 최신으로 변경할 수 있습니다.
# https://github.com/docker/compose/releases
curl -SL https://github.com/docker/compose/releases/download/v2.27.0/docker-compose-linux-x86_64 -o docker-compose
Docker Compose 바이너리 설치
다운로드한 docker-compose 파일을 실행 가능한 경로로 옮기고 실행 권한을 부여합니다.
# 바이너리를 /usr/local/bin 으로 이동
sudo mv docker-compose /usr/local/bin/docker-compose
# 실행 권한 부여
sudo chmod +x /usr/local/bin/docker-compose
모든 설치가 완료된 후, 각 프로그램의 버전을 확인하여 성공적으로 설치되었는지 검증합니다.
# Docker Compose 버전 확인
docker-compose --version
# 출력 예시: Docker Compose version v2.27.0
[appuser@appdev docker-mendix-build_v6.0.1]$ docker-compose --version
