部署私服 xenus 下载https://www.sonatype.com/download‐oss‐sonatype
我下载了两个版本的nexus：
nexus-3.13.0-01-unix.tar.gz
nexus-3.14.0-04-unix.tar.gz
主要是第一个版本不兼容
配置好jdk环境
[root@localhost nexus-3.14.0-04]# java -version java version "1.8.0_181" Java(TM) SE Runtime Environment (build 1.8.0_181-b13) Java HotSpot(TM) 64-Bit Server VM (build 25.181-b13, mixed mode)
解压安装启动
[root@localhost opt]# tar -xvf nexus-3.14.0-04-unix.tar.gz
[root@localhost opt]# cd nexus-3.14.0-04
[root@localhost nexus-3.14.0-04]# sh bin/nexus start

访问测试：
ip:8081
登录账户和密码
ip:8081 admin admin123
点击设置，进入仓库管理，换国内的阿里云仓库地址
<mirror> <id>nexus-aliyun</id> <mirrorOf>*</mirrorOf> <name>Nexus aliyun</name> <url>http://maven.aliyun.com/nexus/content/groups/public</url> </mirror>
将上述http部分复制到下面你的proxy位置代替国外的仓库地址，之后save。
此时去maven的全局配置下配置文件
[root@localhost jeesns]# cd /usr/local/maven/conf [root@localhost conf]# ll total 16 drwxr-xr-x. 2 root root 37 Nov 11 2015 logging -rw-r--r--. 1 root root 10404 Apr 18 14:31 settings.xml -rw-r--r--. 1 root root 3649 Nov 11 2015 toolchains.xml [root@localhost conf]# cp settings.xml settings.xml.bak [root@localhost conf]# vim settings.xml #删除了之前的标签 第一段要添加的内容 134 <id>my-nexus-releases</id> 135 <username>admin</username> 136 <password>admin123</password> 137 </server> 138 <server> 139 <id>my-nexus-snapshot</id> 140 <username>admin</username> 141 <password>admin123</password> 142 </server> 143 </servers> 第二段要添加的内容 157 <mirror> 158 <id>nexus</id> 159 <mirrorOf>*</mirrorOf> 160 <url>http://192.168.171.144:8081/repository/maven-public/</url> 161 </mirror> 第三段要添加的内容 262 <profile> 263 <id>nexus</id> 264 <repositories> 265 <repository> 266 <id>central</id> 267 <url>http://192.168.171.145:8081/repository/maven-public/</url> 268 <releases><enabled>true</enabled></releases> 269 <snapshots><enabled>true</enabled></snapshots> 270 </repository> 271 </repositories> 272 <pluginRepositories> 273 <pluginRepository> 274 <id>central</id> 275 <url>http://192.168.171.145:8081/repository/maven-public/</url> 276 <releases><enabled>true</enabled></releases> 277 <snapshots><enabled>true</enabled></snapshots> 278 </pluginRepository> 279 </pluginRepositories> 280 </profile> 第四段要添加的内容（激活） 291 <activeProfiles> 292 <activeProfile>nexus</activeProfile> 293 </activeProfiles>
如果之前有数据就删了，否则创建过程中会失败
