搭建 Maven Nexus私服

编写docker-compose.yml

version: '3.1'
services:
  nexus:
    restart: always
    image: sonatype/nexus3
    container_name: nexus
    ports:
      - 8081:8081
    volumes:
      - /usr/local/docker/nexus/data:/nexus-data

授权nexus目录

chmod 777 /usr/local/docker/nexus/data

最新版本的nexus的进入宿主机目录/usr/local/docker/nexus/data，在admin.password文件中查询admin用户的密码。登陆之后自动提示修改admin的密码

[root@mail data]# ls
admin.password  db             generated-bundles  karaf.pid  log     restore-from-backup
blobs           elasticsearch  instances          keystores  orient  tmp
cache           etc            javaprefs          lock       port

启动nexus镜像

docker-compose up -d

本机没有nexus镜像，会自动从远端拉取，过程会比较慢。

访问nexus私服

http://ip:8081

到这里，maven的私服基于Docker-Compose就搭建完毕了

使用Nexus私服

settings.xml配置Nexus Repository

<?xml version="1.0" encoding="UTF-8"?>

    <!--激活moodfly的profile -->
    <activeProfiles>
        <activeProfile>moodfly</activeProfile>
    </activeProfiles>

</settings>

发布项目到Nexus

在Maven项目的pom文件内增加对应的distributionManagement

<distributionManagement>
        <repository>
            <id>nexus-releases</id>
            <name>Nexus Release Repository</name>
            <url>http://ip:8081/repository/maven-releases/</url>
        </repository>
        <snapshotRepository>
            <id>nexus-snapshots</id>
            <name>Nexus Snapshot Repository</name>
            <url>http://ip:8081/repository/maven-snapshots/</url>
        </snapshotRepository>
    </distributionManagement>

• SNAPSHOT版本（快照版本）<version>1.0.0-SNAPSHOT</version>

• RELEASE稳定的版本（发布版本）<version>1.0.0-RELEASE</version>

在项目根目录执行mvn deploy
