使用Nginx制作内网yum镜像代理
1. 背景
公司内网服务器不能直接通过Internet上网，但为了与外网通信和同步时间等，会指定那么几台服务器可以访问Internet。这里就是通过能上网的机器作为代理，制作内网使用的yum仓库。
2. 环境需求
- 内网dns（推荐，非必须，因为可使用IP代替）
- 一台能上Internet的服务器A
- 不能上Internet的服务器能与A服务器通信
- 这里示例为CentOS7和Ubuntu16
3. Nginx安装配置
Nginx安装在能上网的A服务器上，安装过程略。
具体一个nginx server配置如下：
# mirrorsserver { listen 80; #listen [::]:80; server_name mirrors.yourdomain.com; index index.html index.htm index.php default.html default.htm default.php; root /home/wwwroot/html;
location /ubuntu/ { proxy_pass http://mirrors.aliyun.com/ubuntu/ ; }
location /centos/ { proxy_pass http://mirrors.aliyun.com/centos/ ; }
location /epel/ { proxy_pass http://mirrors.aliyun.com/epel/ ; }}以上使用阿里云镜像，其镜像版本很全，速度也很快。
