第一步，下载nexus的安装包并解压

链接：http://pan.baidu.com/s/1jIhpZ98 密码：6bqx

如果不能下载给我私信，最近也一直在想把这些东西方github上，但是想想自己老是看不懂，就。。。

第二步，将bin添加到环境变量

F:\javapath\nexus\nexus-2.14.1-01\bin

第三步，修改nexus的配置文件

1、F:\javapath\nexus\nexus-2.14.1-01\bin\jsw\conf\wrapper.conf

找里面有这样一个属性wrapper.java.command，将其指向当前的jdk。

wrapper.java.command=F:\javapath\jdk\jdk1.7.0_80\bin\java

2、F:\javapath\nexus\nexus-2.14.1-01\conf\nexus.properties

修改配置文件的application-port和application-host，分别指向maven私服的端口号和Ip

application-port=8081
application-host=127.0.0.1

第四步，nexus服务的安装

nexus install是将nexus安装到本机服务里，nexus start是启动nexus服务，此时如果访问http://127.0.0.1:8081/nexus

则证明nexus初步跑成功了。

Nexus默认管理用户名和密码为admin/admin123。

第五步，nexus索引的更新，这一步就决定了你的maven私服能不能工作了。

单击左边导航栏的Repositories，选择Central，点击Configuration，里面有一个Download Remote Indexes配置，默认状态是false，将其改为true，‘Save’后，单击Administration==> Scheduled Tasks, 就有一条更新Index的任务，这个是Nexus开始下载中央仓库的索引。由于中央仓库的内容比较多，因此其索引文件比较大，Nexus下载该文件也需要比较长的时间。上班的时间慎用，实在是太耗硬盘了，我这边实测下载速度能到10M/S，更新一次镜像大概要花掉1个小时左右的时间，硬盘一直是100%，电脑卡死，而且我在第一次更新的时候并没有生成Scheduled Tasks，所以并没有索引和镜像的更新，然后重试了两次才好，尤其是maven私服在本地的时候，pom文件增加依赖是瞬间下载。然后就是更新完一次之后基本上就不用再动了，感觉平常跑这个服务队电脑的配置吃的不大，并没有什么影响，只要不手动更新镜像就好。

中央仓库的地址有很多，可以从网上查到，如果感觉到你用的线路很慢的话可以自己手动更改。

hosted仓库，内部项目的发布仓库。

proxy仓库，从远程中央仓库寻找数据的仓库

group仓库，组仓库方便开发人员进行设置的仓库

将多个Repositories添加到public Repositories,我们直接调用就public Repositories的url作为maven仓库的地址就可以

第六步，贴出我的Maven的sitting.xml文件

--><!--| This is the configuration file for Maven. It can be specified at two levels:||  1. User Level. This settings.xml file provides configuration for a single user, |                 and is normally provided in ${user.home}/.m2/settings.xml.||                 NOTE: This location can be overridden with the CLI option:||                 -s /path/to/user/settings.xml||  2. Global Level. This settings.xml file provides configuration for all Maven|                 users on a machine (assuming they're all using the same Maven|                 installation). It's normally provided in |                 ${maven.home}/conf/settings.xml.||                 NOTE: This location can be overridden with the CLI option:||                 -gs /path/to/global/settings.xml|| The sections in this sample file are intended to give you a running start at| getting the most out of your Maven installation. Where appropriate, the default| values (values used when the setting is not specified) are provided.||-->

The mirror site will be the preferred | server for that repository.|--><mirrors><mirror><id>nexus</id><mirrorOf>*</mirrorOf><url>http://127.0.0.1:8081/nexus/content/groups/public</url></mirror></mirrors><!-- profiles| This is a list of profiles which can be activated in a variety of ways, and which can modify| the build process. Profiles provided in the settings.xml are intended to provide local machine-| specific paths and repository locations which allow the build to work in the local environment.|| For example, if you have an integration testing plugin - like cactus - that needs to know where| your Tomcat instance is installed, you can provide a variable here such that the variable is | dereferenced during the build process to configure the cactus plugin.|| As noted above, profiles can be activated in a variety of ways. One way - the activeProfiles| section of this document (settings.xml) - will be discussed later. Another way essentially| relies on the detection of a system property, either matching a particular value for the property,| or merely testing its existence. Profiles can also be activated by JDK version prefix, where a | value of '1.4' might activate a profile when the build is executed on a JDK version of '1.4.2_07'.| Finally, the list of active profiles can be specified directly from the command line.|| NOTE: For profiles defined in the settings.xml, you are restricted to specifying only artifact|       repositories, plugin repositories, and free-form properties to be used as configuration|       variables for plugins in the POM.||--><profiles><!-- profile| Specifies a set of introductions to the build process, to be activated using one or more of the| mechanisms described above. For inheritance purposes, and to activate profiles via <activatedProfiles/>| or the command line, profiles have to have an ID that is unique.|| An encouraged best practice for profile identification is to use a consistent naming convention| for profiles, such as 'env-dev', 'env-test', 'env-production', 'user-jdcasey', 'user-brett', etc.| This will make it more intuitive to understand what the set of introduced profiles is attempting| to accomplish, particularly when you only have a list of profile id's for debug.|| This profile example uses the JDK version to trigger activation, and provides a JDK-specific repo.<profile><id>jdk-1.4</id><activation><jdk>1.4</jdk></activation><repositories><repository><id>jdk14</id><name>Repository for JDK 1.4 builds</name><url>http://www.myhost.com/maven/jdk14</url><layout>default</layout><snapshotPolicy>always</snapshotPolicy></repository></repositories></profile>--><!--| Here is another profile, activated by the system property 'target-env' with a value of 'dev',| which provides a specific path to the Tomcat instance. To use this, your plugin configuration| might hypothetically look like:|| ...| <plugin>|   <groupId>org.myco.myplugins</groupId>|   <artifactId>myplugin</artifactId>|   |   <configuration>|     <tomcatLocation>${tomcatPath}</tomcatLocation>|   </configuration>| </plugin>| ...|| NOTE: If you just wanted to inject this configuration whenever someone set 'target-env' to|       anything, you could just leave off the <value/> inside the activation-property.|<profile><id>env-dev</id><activation><property><name>target-env</name><value>dev</value></property></activation><properties><tomcatPath>/path/to/tomcat/instance</tomcatPath></properties></profile>--><profile><id>nexus</id><repositories><repository><id>dp-repo</id><name>Repository for ane56</name><url>http://127.0.0.1:8081/nexus</url><releases><enabled>true</enabled></releases><snapshots><enabled>true</enabled><updatePolicy>always</updatePolicy><checksumPolicy>ignore</checksumPolicy></snapshots><layout>default</layout></repository><repository><id>releases</id><url>http://127.0.0.1:8081/nexus/content/repositories/releases</url></repository><repository><id>central</id><url>http://central</url><releases><enabled>true</enabled></releases><snapshots><enabled>true</enabled></snapshots></repository></repositories><pluginRepositories><pluginRepository><id>central</id><url>http://central</url><releases><enabled>true</enabled></releases><snapshots><enabled>true</enabled></snapshots></pluginRepository></pluginRepositories></profile></profiles><!-- activeProfiles| List of profiles that are active for all builds.|<activeProfiles><activeProfile>alwaysActiveProfile</activeProfile><activeProfile>anotherAlwaysActiveProfile</activeProfile></activeProfiles>--><activeProfiles><activeProfile>nexus</activeProfile></activeProfiles>
