nexus

安装完nexus后，默认存放repository地址是\sonatype-work\nexus\storage\central

登陆http://192.168.74.129:8081/nexus，选中Central，打开Configuration选项卡，可以看到默认存储位置：Default Local Storage Location为：/usr/local/install/nexus/sonatype-work/nexus/storage/central；如需修改存储位置改Override Local Storage Location

nexus默认用户(Users)：

Nexus 预定义了三个用户，这三个用户对应了三个权限级别，可以从右侧的菜单栏查看权限信息：

  • admin：该用户拥有对Nexus服务的完全控制，默认密码为 admin123
  • deployment：该用户能够访问Nexus，浏览仓库、搜索，并且上传部署构件，但无法对Nexus进行任何配置，默认密码为 deployment123
  • anonymous：该用户对应了所有未登录的匿名用户，可以浏览仓库并搜索

nexus角色(Roles)：

Nexus 预定义了一些常用且重要的角色：

  • UI：Basic UI Privileges：包含了访问Nexus界面必须的最基本权限
  • UI：Repository Browser：包含了浏览仓库页面所需要的权限
  • UI：Search：包含了访问快速搜索页面说需要的权限
  • Repo：All Repositoryies（Read）：给予用户读取所有仓库内容的权限，没有仓库的读权限用户将无法在仓库页面上看到实际的仓库内容，也无法使用Maven从仓库下载构件
  • Repo：All Repositoryies（Full Control）：给予用户完全控制所有仓库内容的权限。

nexus为项目分配独立的仓库

如果所有项目都部署快照及发布构件至同样的仓库，就会存在潜在的冲突及安全问题，因此我们可以为每个项目分配独立的仓库，并且只将仓库的部署、修改和删除权限赋予该项目的成员，其他用户只能读取、下载和搜索该仓库的内容。

  • 创建项目的独立仓库
  • 点击 Repositories -> Add Hosted Repositor 打开创建仓库的页面，输入仓库信息，点击保存:

  • 创建仓库：

  • 创建指定仓库的权限
  • 点击 Privileges -> Add Repository Target Privilege 打开权限页面，在页面中的 Repository 选择新创建的仓库，Repository Target 中选择 All Maven2

  • 创建角色并指定权限
  • 点击 Roles -> Add Nexus Role 打开角色页面，输入基本信息后，增加权限，将创建的权限根据需求增加

  • 创建用户并指定角色
  • 点击 Users -> Add Nexus User 打开创建用户页面，输入用户基本信息并增加角色

配置maven使用nexus（从nexus下载jar）

  • 1）在maven安装目录中找到maven的全局配置settings.xml文件
  • 2）将settings.xml修改为如下配置(可以从nexus下载依赖的包)：
    <?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">

       | Unless otherwise specified (by system property or command-line switch), the first proxy

       | This is a list of mirrors to be used in downloading artifacts from remote repositories.  
       |   
       | It works like this: a POM may declare a repository to use in resolving certain artifacts.  
       | However, this repository may have problems with heavy traffic at times, so people have mirrored  
       | it to several places.  
       |  
       | That repository definition will have a unique id, so we can create a mirror reference for that  
       | repository, to be used as an alternate download site. The mirror site will be the preferred   
       | server for that repository.

      <activeProfiles>  
        <activeProfile>development</activeProfile>  
      </activeProfiles>  
    </settings>

deploy到demorepository的配置：

  • ideal使用的setting.xml里<servers>节点中加入认证信息：
    • 如果为配置server认证信息，会报错Return code is: 401, ReasonPhrase: Unauthorized. 
      <server>
          <id>demoRepository</id>
          <username>admin</username>
          <password>admin123</password>
      </server>
  • 配置pom的distributionManagement，可以从nexus的仓库里获取，如下图：
  <distributionManagement>
    <snapshotRepository>
      <id>demoRepository</id>
      <url>http://192.168.74.129:8081/nexus/content/repositories/demoRepository</url>
    </snapshotRepository>
  </distributionManagement>

  • 运行项目里deploy，可以看到通过http协议发布到了服务器上：
