docker-compose安装Nexus

一、Nexus

Nexus是一个强大的Maven仓库管理器，它极大地简化了自己内部仓库的维护和外部仓库的访问。利用Nexus你可以只在一个地方就能够完全控制访问 和部署在你所维护仓库中的每个Artifact。Nexus是一套“开箱即用”的系统不需要数据库，它使用文件系统加Lucene来组织数据。Nexus 使用ExtJS来开发界面，利用Restlet来提供完整的REST APIs，通过m2eclipse与Eclipse集成使用。Nexus支持WebDAV与LDAP安全身份认证。

二、部署规划

服务器IP 192.168.113.48
端口 8931
安装目录 /home/work/docker-nexus
数据映射目录 /home/work/docker-nexus/data

三、安装Nexus

  • 创建安装目录，进入到安装目录中编辑并保存docker-compose.yml文件

    vim docker-compose.yml

    version: '3'
services:
  nexus:
    image: 'sonatype/nexus3'
    container_name: nexus
    restart: always
    environment:
      - TZ=Asia/Shanghai
    ports:
      - '8931:8081'
    volumes:
      - '/home/work/docker-nexus/data:/nexus-data'

  • 在安装目录下启动服务

    [root@node03 docker-nexus]# docker-compose up -d
Creating network "docker-nexus_default" with the default driver
Creating nexus ... done
[root@node03 docker-nexus]# docker-compose logs -f

  • 启动后查看日志，发现提示权限不足，为数据映射目录加上权限即可

    [root@node03 docker-nexus]# chmod 777 /home/work/docker-nexus/data/
You have new mail in /var/spool/mail/root
[root@node03 docker-nexus]# docker-compose ps
Name               Command               State           Ports         
-----------------------------------------------------------------------
nexus   sh -c ${SONATYPE_DIR}/star ...   Up      0.0.0.0:8931->8081/tcp

四、验证Nexus

  • 在浏览器中输入IP:端口，点击页面右上角登录，根据页面提示查找到初始密码，然后将初始密码复制

    若输入ip:端口后，浏览器无法访问页面，可以稍等一会，查看日志确保nexus启动完成后再访问

    [root@node03 docker-nexus]# cat data/admin.password 
b05c1771-6be1-4cb2-9b4e-5cffb610099d

    BuV6Df.png

  • 登录后会有一个弹窗，要求给admin用户重新设置一个新的密码，请记住这个设置的密码（本次安装设置的密码为admin_qazwsx）

    BuVcb8.png

  • 点击"next"，弹窗提示是否允许匿名用户访问，根据自己需求选择即可，本次安装选择"开启匿名访问"

  • Nexus安装成功，再根据需求进行相关配置即可。
