liumiaocn/nexus repository overview

这里写图片描述 Nexus作为私库管理最为流行的工具之一，用于包的管理和Docker镜像管理的私库管理场景中非常常用。Easypack利用最新版本的oss版Nexus作为基础镜像用于提供类似服务。本文将同时给出具体步骤结合Maven以实现使用Nexus进行包的管理。

#Why Nexus 3 这里整理了为什么使用Nexus 3的一些理由，在做选型的时候可以做一个简单参照。

#下载镜像

#创建Proxy私库 ##仓库类型具体仓库类型主要分为hosted/proxy/group三种。具体含义如下：

项目	详细说明
hosted	本地存储，像官方仓库一样提供本地私库功能
proxy	提供代理其他仓库的类型
group	组类型，可以组合多个仓库为一个地址提供服务

##创建Maven仓库使用Nexus官方镜像，我们会试图总结出最佳的实践方式，然后再此基础上不断地完善和进步。

项目	详细说明
实践1	根据项目情况，结合Maven特点将Snapshot和Release进行分离，分别创建snapshot和release的host类型仓库
实践2	活用group类型，提供统一的对外URL
实践3	可以使用-v将本地卷挂载进去，或者直接使用Named volume或者Data container使得数据从nexus容器中分离，方便数据的管理和备份等

##创建Snapshot的仓库在Maven的Pom文件中的version标签内定义的以-SNAPSHOT结尾的版本tag统一在如下snapshot仓库中进行管理。 ###创建blob store 在创建仓库之前，建议为每个仓库创建blob store。

项目	详细说明
实践4	为每个仓库创建一个blob store,这样其数据会在/nexus-data下分别管理起来

###创建之后这里写图片描述

选择Server administration and configuration ->左侧的Administration -> repository -> repositories 这里写图片描述

###创建仓库

项目	详细说明
类型	maven2(hosted)

###创建以下项目以外，使用default设定。

项目	详细说明
name	maven-snapshots
version policy	snapshot
deployment policy	allow redeploy
blob store	maven-snapshots

确认

##创建release的仓库在Maven的Pom文件中的version标签内定义的以-SNAPSHOT结尾以外的版本tag统一在如下release仓库中进行管理。创建release的仓库步骤以及所用到的信息如下：

项目	详细说明
类型	maven2(hosted)
name	maven-releases
deployment policy	allow redeploy
blob store	maven-releases

##创建proxy仓库创建proxy仓库，default以外的值设定如下：

项目	详细说明
类型	maven2(proxy)
name	maven-central
location of the remote repository being proxied	https://repo1.maven.org/maven2⁠
blob store	maven-central
Maximum component age	1440

最后确认的时候才发现上图中的location of the remote repository being proxied选项写错了，无法下载到本地，所以建议URL方式的设定之前先手动确认一下是否正确这里写图片描述

##创建group仓库为提供统一的URL进行管理，按照如下方式创建group仓库:

项目	详细说明
类型	maven2(group)
name	maven-group
blob store	maven-central
member repositories	maven-snapshots
member repositories	maven-releases
member repositories	maven-central

#安装Maven 具体安装请参看如下文章：

项目	详细
容器方式	http://blog.csdn.net/liumiaocn/article/details/57064776⁠
裸机方式	http://blog.csdn.net/liumiaocn/article/details/61920553⁠
此处为演示方便使用裸机方式，直接安装到centos上。

demo项目	spring boot 的demo项目，显示hello world
生成参照	http://blog.csdn.net/liumiaocn/article/details/53442364⁠
注意事项：上面的参照的时候spring boot用的1.4.2, 现在稳定版本在1.5.2，不过使用SPRING INITIALIZR可以不用意识。或者使用自己的Maven项目，在pom中类似的设定即可。
