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.ymlversion: '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

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
-
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）
-
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。
