1 . 私服简介
私服是架设在局域网的一种特殊的远程仓库，目的是代理远程仓库及部署第三方构件。有了私服之后，当 Maven 需要下载构件时，直接请求私服，私服上存在则下载到本地仓库；否则，私服请求外部的远程仓库，将构件下载到私服，再提供给本地仓库下载。
我们可以使用专门的 Maven 仓库管理软件来搭建私服，比如：Apache Archiva，Artifactory，Sonatype Nexus。这里我们使用 Sonatype Nexus。
2 . 安装Nexus
2.1 下载Nexus
Nexus 专业版是需要付费的，这里我们下载开源版 Nexus OSS。Nexus 提供两种安装包，一种是包含 Jetty 容器的 bundle 包，另一种是不包含容器的 war 包。下载地址：https://help.sonatype.com/display/NXRM2/Download+Archives+-+Repository+Manager+OSS
2.2 安装nexus
添加用户：
groupadd nexus
useradd -d /home/nexus -g nexus nexus
下载好以后，使用如下命令对nexus-2.14.15-01-bundle.tar.gz进行解压
tar –zxvf nexus-2.14.15-01-bundle.tar.gz
解压完以后会得到两个目录：nexus-2.14.15-01 和 sonatype-work，一个放的是nexus程序，一个放的是仓库类信息。
nexus-2.14.15-01目录下存放着如下目录
Bin:可执行文件
Conf:配置文件
Lib:库文件
配置nexus
# Jetty section
application-port=8081
application-host=0.0.0.0
nexus-webapp=${bundleBasedir}/nexus
nexus-webapp-context-path=/nexus
# Nexus section
nexus-work=${bundleBasedir}/../sonatype-work/nexus
runtime=${bundleBasedir}/nexus/WEB-INF
# orientdb buffer size in megabytes
storage.diskCache.bufferSize=4096
启动nexus,在启动前确保java环境以及安装好了。
启动nexus:
到bin目录下：./nexus start
访问nexus
在浏览器进行访问。地址：http://ip:端口/nexus
3配置nexus
Nexus常用功能就是：指定私服的中央地址、将自己的Maven项目指定到私服地址、从私服下载中央库的项目索引、从私服仓库下载依赖组件、将第三方项目jar上传到私服供其他项目组使用。
开启Nexus服务后访问url地址http://localhost:8081/nexus/(推荐使用自己的ip地址)，之后登录系统，用户名密码分别是：admin/admin123.
最频繁的就是点击左侧菜单栏的Repositories按钮
一般用到的仓库种类是hosted、proxy。Hosted代表宿主仓库，用来发布一些第三方不允许的组件，比如Oracle驱动、比如商业软件jar包。Proxy代表代理远程的仓库，最典型的就是Maven官方中央仓库、JBoss仓库等等。如果构建的Maven项目本地仓库没有依赖包，那么就会去这个代理站点去下载，那么如果代理站点也没有此依赖包，就回去远程中央仓库下载依赖，这些中央仓库就是proxy。代理站点下载成功后再下载至本机。笔者认为，其实Maven这个自带的默认仓库一般情况下已经够大多数项目使用了。特殊情况时在配置新的仓库，指定url即可，一般熟悉ExtJS的人操作这个Nexus都没什么问题，单词不是很难，不明白的查查单词基本差不多。就是如果Sonatype公司对其做了国际化的处理就更好了。
(1)hosted 类型的仓库，内部项目的发布仓库
(2)releases内部的模块中release模块的发布仓库
(3)snapshots发布内部的SNAPSHOT模块的仓库
(4)3rd party第三方依赖的仓库，这个数据通常是由内部人员自行下载之后发布上去
(5)proxy 类型的仓库，从远程中央仓库中寻找数据的仓库
(6)group 类型的仓库，组仓库用来方便我们开发人员进行设置的仓库
maven项目索引下载Maven项目索引，项目索引是为了使用者能够在私服站点查找依赖使用的功能
保存后后台会运行一个任务，点击菜单栏的Scheduled Tasks选项即可看到有个任务在RUNNING。 下载完成后，Maven索引就可以使用了，在搜索栏输入要搜索的项，就可以查到相关的信息。例如spring-core
就可以检索出它的相关信息，包括怎么配置依赖信息。我们要想使用这个私服仓库，先在项目pom中配置相关私服信息指定仓库。
指定插件仓库：
这样只有本项目才在私服下载组件这样这个Maven项目构建的时候会从私服下载相关依赖。当然这个配置仅仅是在此项目中生效，对于其他项目还是不起作用。如果相对Maven的其他项目也生效的话。需要修改全局的settings.xml文件。
追加激活profile:
之后所有本机的Maven项目就在私服下载组件。（这样比较好）
项目的发布,在项目的pom文件中添加如下配置:
注意配置了还是发布项目到私服失败，原因为没有权限配置权限在settings.xml
然后运行发布clean deploy在控制台发布成功然后进入到私服上的仓库中，看一下确实存在刚刚发布的项目
宿主库——3rd party假如我们下载了Oracle的驱动程序jar包想给其他项目组使用，就需要上传该jar包。选中宿主库——3rd party，之后选择Artifact Upload上传至宿主空间。
最后点击上传
3.1索引更新
(1) 在线更新索引安装配置完成Nexus后，电脑联网状态下，Nexus会自动下载索引文件。下载好的索引文件存放在目录：sonatype-work\nexus\indexer
(2) 手动更新索引网络环境不佳，或者在线更新有问题时，可以选择手动添加索引方式。到http://repo.maven.apache.org/maven2/.index/上下载：
到http://search.maven.org下载特定解压文indexer-cli-5.1.1.jar
把这几个文件放在同一个文件路径下面，从cmd进入到这个路径里，输入命令：
nohup java -jar indexer-cli-5.1.1.jar -u nexus-maven-repository-index.613.gz -d indexer &
执行完之后，把indexer文件夹下的所有内容都复制到%nexus-home%\sonatype-work\nexus\indexer\central-ctx下面。
重新启动nexus，进入管理界面，选择central->Browse Index，就看到更新的索引了。注意：nexus是需要重新启动的，我是在做上面的所有步骤之前，先停掉nexus，等上面四个步骤完成之后，再启动nexus的。
仓库迁移
Nexus的构件仓库都保存在sonatype-work目录中，该目录的位置由nexus/conf/nexus.properties配置文件指定。
仓库迁移需要两个过程：备份和还原
备份仓库：将sonatype-work文件夹整体备份即可，也可以选择只备份最重要的两个文件夹索引（indexer）和仓库（storage）
还原仓库：将备份好的sonatype-work文件拷贝到新的服务器中。然后修改nexus/conf/nexus.properties配置文件，重新指定仓库的目录。

查看下载速度，很慢
刷新页面，可以看到私服里面有很多了
可以看到，本地仓库也已经有了。下次本地仓库需要包，直接去私服里面下载
已经打包完成

[root@mcw12 demo1]#
之前上面的pom.xml里面配置了id,但是在maven的setting里面没有配置这个id，需要配置一下，指定nexus的用户和密码
然后再次执行部署，可以看的已经在往nexus私服上传
私服上可以看到我们的war包
点击查看信息
release里面还没有
复制上面的地址看看是否能下载，不可以，下载的是个index.html文件
要想下载，可以用仓库地址，拼接上path
我上传的这个仓库地址是：http://10.0.0.25:9081/repository/maven-snapshots/，配置文件，或者页面中可以copy出来
如下，成功下载

运行这个包，然后访问这个机器的8080端口
可以看到，部署到私服，然后从私服下载下来的这个包，成功运行，并提供web服务
nexus错误
nexus无法启动
普通用户无法start启动，并且没有任何日志输出。然后使用run命令，可以看到终端报错。报错都是权限问题。

因为很多文件是root用户的，nexus用户没有权限操作
所以用root启动，用root启动之后，端口没有开启，然后就用nexus再次执行了一次start启动，然后端口就开启了，不过端口开启应该跟这个普通用户的操作没有关系，可能只是端口开启慢了罢了。有时间再验证
