Nexus 是一个强大的 Maven 和其它仓库的管理器，它极大地简化了自己内部仓库的维护和外部仓库的
访问。
案列1：配置maven仓库
首先建立一个blob stores
再建立 repository，放到之前建立的blob stores
配置maven.
[20:15:52 root@noise spring-boot-helloWorld]#cat /etc/maven/settings.xml
<mirror>
<id>nexus-aliyun</id>
<mirrorOf>*</mirrorOf>
<name>Nexus aliyun</name>
<url>http://10.0.0.205:8081/repository/mvn-t1-repos/</url>
</mirror>
# 编译一个java程序
[20:15:52 root@noise spring-boot-helloWorld]#mvn clean package -Dmaven.test.skip=true
。。。。。。

查看此时仓库的maven，已缓存了当前下面的maven数据，web上面的blob count也能知道
[20:17:38 root@noise ~]#du -h /data/blobs/Mvn-t1
54M /data/blobs/Mvn-t1
案列2：apt仓库
建立blob stores
创建repository
复制路径更新到source list
[20:24:51 root@noise spring-boot-helloWorld]#cat /etc/apt/sources.list deb http://10.0.0.205:8081/repository/apt-source-t1/ bionic main restricted universe multiverse deb-src http://10.0.0.205:8081/repository/apt-source-t1/ bionic main restricted universe multiverse deb http://10.0.0.205:8081/repository/apt-source-t1/ bionic-security main restricted universe multiverse deb-src http://10.0.0.205:8081/repository/apt-source-t1/ bionic-security main restricted universe multiverse deb http://10.0.0.205:8081/repository/apt-source-t1/ bionic-updates main restricted universe multiverse deb-src http://10.0.0.205:8081/repository/apt-source-t1/ bionic-updates main restricted universe multiverse deb http://10.0.0.205:8081/repository/apt-source-t1/ bionic-proposed main restricted universe multiverse deb-src http://10.0.0.205:8081/repository/apt-source-t1/ bionic-proposed main restricted universe multiverse deb http://10.0.0.205:8081/repository/apt-source-t1/ bionic-backports main restricted universe multiverse deb-src http://10.0.0.205:8081/repository/apt-source-t1/ bionic-backports main restricted universe multiverse [20:24:54 root@noise spring-boot-helloWorld]#apt update ......

此时仓库数据已更新，我们用sl测试下,安装成功，且执行成功

yum仓库和apt仓库类似，这里不做过多介绍
