- Nexus Repository 란 ? maven에서 사용할 수 있는 오픈소스 repository
- 본 문서는 Deploy 위주로 작성되어 설치와 설정은 간략하게 나와있습니다.
- Nexus Repository Deploy 페이지를 보시면 설치부터 미러링까지 보다 자세하게 알 수 있습니다.
- 설치환경
- Host OS : Windows 10 Pro
- Guest (VM Virtual Box) OS : CentOS 7
- Guest에 Nexus Repository 설치
Vagrant + CentOS 7에서 Nexus Repository Server 설치
Vagrant 접속
- Vagrant로 VM VirtualBox를 실행하려면, Windows command 창에
vagrant up
명령어 실행 후vagrant ssh
명령어로 shell 을 실행합니다. - (Vagrant Provision을 사용해도 되지만 설치 과정에서 에러가 생길 수 있어서 shell로 접속하여 설치하는게 안전합니다)
패키지 다운로드
- Nexus는
3.29.2-02 버전을 설치하였습니다.
- 설치할 Nexus 3 version 목록은 https://help.sonatype.com/repomanager3/download/download-archives---repository-manager-3 를 참고하시면 됩니다.
- 설치 과정은 https://help.sonatype.com/repomanager3/installation 를 참고하시면 됩니다.
- 설치 이전에 jdk 1.8 버전이 설치되어 있어야 합니다.
설치 과정은 다음과 같습니다. (root로 설치하는 것이 편합니다)
# nexus repository 패키지 설치 $ wget install https://download.sonatype.com/nexus/3/latest-unix.tar.gz --no-check-certificate # 설치 후 압축 해제 $ tar -xvf latest-unix.tar.gz # 압축 해제한 파일을 /opt 디렉토리 밑에 옮김 $ sudo mv nexus-3.29.2-02 /opt/
설치 후 기본 설정
- 설치 후 nexus-default.properties 파일을 편집모드로 열어 application-port=8089 부분의 포트를 변경합니다. (보통 8080 으로 설정합니다)
$ cd /opt/nexus-3.29.2-02/etc $ sudo vi nexus-default.properties
- 계정과 그룹을 생성합니다.
$ sudo groupadd nexus && adduser nexus -g nexus
서비스 등록
- 서비스 등록에는 많은 방법이 있는데 저는 systemd를 이용하는 방식을 사용하였습니다.
- 서비스 등록은 https://help.sonatype.com/repomanager3/installation/run-as-a-service 을 참고하시면 자세히 나와있습니다.
- nexus.service를 편집기로 열어 다음의 내용을 작성합니다. (저는 vagrant 계정이 기본으로 되어있어 vagrant로 설정하였습니다.)
편집기 명령어
$ sudo vi /etc/systemd/system/nexus.service
nexus.service
[Unit]252C Description=nexus service After=network.target [Service] Type=forking LimitNOFILE=65536 ExecStart=/opt/nexus-3.29.2-02/bin/nexus start ExecStop=/opt/nexus-3.29.2-02/bin/nexus stop User=nexus Restart=on-abort TimeoutSec=600 [Install] WantedBy=multi-user.target
- 이후 다음의 명령어들을 실행하여 재시작시 실행되도록 설정합니다.
service 등록
sudo systemctl daemon-reload sudo systemctl enable nexus.service sudo systemctl start nexus.service
- log는 tail -f /opt/sonatype-work/nexus3/log/nexus.log 명령어로 확인할 수 있습니다.
- 마지막으로 다음의 화면이 나오면 Nexus 서버 접속에 성공한 것입니다!
브라우저 접속
- 브라우저로 접속하려면 다음의 URL로 접속할 수 있습니다. (http://도메인:포트번호/)
- 다음은 접속한 화면입니다.
외부 Repositories 등록 후 Windows에서 Nexus Server 미러링
외부 Repositories 등록
- 다음은 외부 저장소를 등록하는 화면입니다. 저는 spring repository를 등록하였습니다.
- 저장소는 test라는 Blob store를 따로 생성하고 지정하였습니다. (저장소는 Blob stores 메뉴를 보시면 됩니다.)
settings.xml 파일 생성 및 미러링
- 다음은 Windows 환경에서 C:/Users/User/.m2 경로에 settings.xml 파일을 만들고 VMBox의 Nexus Repository 미러링 내용을 작성합니다.
settings.xml
<?xml version="1.0" encoding="UTF-8"?> <settings xmlns="http://maven.apache.org/SETTINGS/1.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/SETTINGS/1.0.0 http://maven.apache.org/xsd/settings-1.0.0.xsd"> <mirrors> <mirror> <id>maven-spring-public</id> <name>maven-spring-public</name> <url>http://192.168.33.10:8089/repository/spring-central/</url> <mirrorOf>central</mirrorOf> </mirror> </mirrors> </settings>
- IntelliJ라는 IDE 툴을 이용하여 spring boot starter 프로젝트를 생성한 후 Nexus repository를 미러링 하여 jar 파일을 다운로드 받았습니다.
- 이 때 저는 spring repository 만 추가되어 있기 때문에 다른 패키지들을 다운로드 할 때 에러가 발생합니다.
- 그래서 실제로 maven install을 할 때는 이미 존재하는 maven-public repository를 이용했습니다.

- Maven install이 끝나면 다음과 같은 component 들이 등록되어 있는것을 확인할 수 있습니다.
maven deploy 커맨드로 Spring Boot의 빌드한 JAR 파일을 Nexus에 배포
- Repositories에 등록되어 있는 maven-snapshots repository를 이용하여 배포할 계획입니다.
- 정리하자면, maven-public repository에서 pom.xml에 있는 파일들을 미러링→ 해당 jar 파일들을 다운로드 → maven-snapshots repository에 배포한다는 계획입니다.
- 다음은 settings.xml에 deploy 설정을 추가한 내용입니다.
