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。
另：
apt-mirror能够将官方镜像下载到本地，并保证目录结构与其一致，但是不能对镜像仓库进行修改。如果想要修改镜像仓库，需要使用reprepro。
1、安装apt-mirror
# aptitude update
# aptitude install -y apt-mirror
# dpkg -L apt-mirror

# vim /etc/apt/mirror.list
set base_path /docker/debian_mirror
set mirror_path $base_path/mirror
set skel_path $base_path/skel set var_path $base_path/var set cleanscript $var_path/clean.sh set defaultarch <running host architecture> set postmirror_script $var_path/postmirror.sh set run_postmirror 0 set nthreads 40 set _tilde 0 deb-amd64 http://archive.debian.org/debian squeeze main deb-amd64 http://archive.debian.org/debian squeeze-lts main3、手动运行apt-mirror下载镜像

End time: Mon Aug 21 21:38:48 2017 0 bytes in 0 files and 0 directories can be freed. Run /docker/debian_mirror/var/clean.sh for this purpose.4、设置定时任务，定时与官方源同步
# vim /etc/cron.d/apt-mirror
0 0 * * * apt-mirror > /docker/mirror.log 2>&15、设置发布目录软链接
# ln -sv /docker/debian_mirror/mirror/archive.debian.org /docker/mirror6、配置nginx发布镜像目录
# cd /usr/local/nginx/conf/vhosts/
# vim debian_mirror.conf
server {
listen 8081; server_name debian_mirror; root /docker/mirror location / { autoindex on; } access_log /usr/local/nginx/logs/debian_mirror.access.log oupeng_logs; error_log /usr/local/nginx/logs/debian_mirror.error.log; } # /usr/local/nginx/sbin/nginx -t # /usr/local/nginx/sbin/nginx -s reload7、找一台debian6的机器添加本地源测试
# vim /etc/apt/sources.list
