一、使用场景

在生产环境中，我们不可能所有的服务器都能连接外网更新RPM包，比较理想的环境是：有一台Linux服务器可以连接外网，剩余的服务器通过这台YUM服务器更新。以前比较传统的做法是先把包下载到内网中的YUM服务器上，然后通过createrepo命令生成本地仓库，其余服务器通过HTTP访问这个链接，这种做法比较费时费事。有没有一种比较好的方式，让我们直接通过这台服务器代理连接到公网的163、阿里 YUM仓库呢，这就是本次介绍的Nexus代理。无论你的客户机是CentOS6还是CentOS7又或者是Ubuntu，不论你是想用YUM还是PIP又或者是NPM包管理器，Nexus都能满足你的需求。

二、安装Nexus

这里我使用CentOS7作为YUM Repository代理服务器

三、配置Nexus

1.  1.  使用浏览器打开http://IP:8081/，用户名密码是admin:admin123
    2.  点击配置->Repositories->选择类型（yum proxy）
    3.  自定义一个名字，例如：yum-proxy  
        
    4.  输入URL: http://mirrors.163.com/centos/
    5.  保存

四、客户机配置yum repo文件

五、附上163服务器CentOS7 repo文件内容

参考这个地方。。

因为我的链接里面没有取到对应的变量值。。。所以URL就是错误的。。。所以我就直接写死了。。。![尴尬][awkward.gif]
