debian官方提供了脚本ftpsync来搭建源镜像，而 apt-mirror 是一个更简单便捷的源镜像搭建工具。
安装 apt-mirror
sudo apt-get install apt-mirror
配置文件/etc/apt/mirror.list只要修改很少的地方，大部分使用默认值即可。
这里使用中科大镜像 ftp.cn.debian.org 作为上游镜像，只镜像 debian jessie amd64 架构，不镜像源代码包。

开启自动同步
只需 root 权限 cron 自动运行 apt-mirror 命令即可。
# m h dom mon dow command 0 0 * * * apt-mirror
发布镜像服务
使用nginx发布源镜像
将 apt-mirror 的镜像目录链接到/var/www/mirror
# ln -sf /var/spool/apt-mirror/mirror/ftp.cn.debian.org/ mirror
然后将nginx默认主机default(或者单独虚拟主机)的根目录设置为/var/www/mirror,并开启目录列表
root /var/www/mirror
location / {
autoindex on;
}
其他机器就可以正常使用新建的源镜像了。
