maven私有仓库之nexus简单使用

概述

Nexus是Sonatype公司开发的一款开源的仓库管理系统，是目前最流行的私有仓库解决方案，主要用于存储和管理各类二进制工件（Artifact），包括Java Maven依赖、npm包、Docker镜像、PyPI包、RPM包等等。

Nexus的核心价值

依赖加速：缓存公共仓库的依赖包，大幅提升构建速度，减少外网带宽消耗
私有包管理：存储企业内部开发的私有包，实现内部组件共享与版本管理
版本可控：统一管理所有依赖版本，避免"依赖地狱"问题
安全审计：对依赖包进行安全漏洞扫描，降低供应链攻击风险
构建稳定性：避免公共仓库故障、网络波动导致的构建失败
合规管控：控制依赖包的引入来源，满足企业合规要求

Docker部署Nexus

复制代码

# 这里指定了镜像源，拉取镜像
root@master:~# docker pull  docker.1ms.run/sonatype/nexus3

# 创建数据卷
root@master:~# docker volume create nexus-data

# 创建容器
root@master:~# docker run -d --name nexus3 -p 8081:8081 --cpus 2 --memory 4GB --restart always -v nexus-data:/nexus-data docker.1ms.run/sonatype/nexus3

访问测试，这里需要等待大概1分钟左右，服务在启动

http://${ip}:8081

ip输入你自己的

用户名默认为root，初始密码会自动生成在一个文件中，看下面的获取方式

复制代码

# 查看数据卷的位置
root@master:/var/lib/docker/volumes/nexus-data/_data# docker volume inspect nexus-data
[
    {
        "CreatedAt": "2026-07-17T11:23:18+08:00",
        "Driver": "local",
        "Labels": null,
         # 这里是真正存在的地方
        "Mountpoint": "/var/lib/docker/volumes/nexus-data/_data",
        "Name": "nexus-data",
        "Options": null,
        "Scope": "local"
    }
]

# 查看admin.password 文件
root@master:/var/lib/docker/volumes/nexus-data/_data# cat /var/lib/docker/volumes/nexus-data/_data/admin.password 
6dcd4165-2572-4c2e-bce7-ee3035a5fce1

登录之后会让你重新输入新的密码，我这里使用huangsirDevops

配置nexus的镜像源

默认的nexus镜像源为apache的，在国内访问可能会访问不通或者很慢，这里替换成阿里云的镜像源

依次点击settings，Repositories、maven- central
下拉找到proxy，配置remote storage即可

阿里云镜像加速地址

http://maven.aliyun.com/nexus/content/groups/public/

最后点击save即可

配置maven连接使用nexus

maven使用参考这篇文章：maven使用详解

连接nexus有两种方式，一个是局部连接，一个是全局连接方式

局部就是修改Java项目中的pom.xml文件

全局就是修改maven的settings.xml文件

这里我使用全局方式，修改maven配置文件

复制代码

root@master:~# cat /usr/local/maven/conf/settings.xml
<?xml version="1.0" encoding="UTF-8"?>
<settings xmlns="http://maven.apache.org/SETTINGS/1.2.0"
          xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
          xsi:schemaLocation="http://maven.apache.org/SETTINGS/1.2.0 https://maven.apache.org/xsd/settings-1.2.0.xsd">
