ubuntu14.04用apt-mirror 制作ubuntu本地镜像源
sudo apt-get install apt-mirror
首先修改/etc/apt/mirror.list，使用cn.archive.ubuntu.com的源作镜像，即在所有archive.ubuntu.com前加上cn.：gksu gedit /etc/apt/mirror.list，内容如下
############# config ##################
#
# set base_path /var/spool/apt-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
# set postmirror_script $var_path/postmirror.sh
# set run_postmirror 0
set nthreads 20
set _tilde 0
#
############# end config ##############

clean http://cn.archive.ubuntu.com/ubuntu

然后运行
apt-mirror
出错：
~$ apt-mirror
flock() on closed filehandle LOCK_FILE at /usr/bin/apt-mirror line 206.
apt-mirror is already running, exiting at /usr/bin/apt-mirror line 209.
ls -l 查看/usr/bin/apt-mirror的权限： drwxr-xr-x 5 apt-mirror apt-mirror 4096 11\u6708 10 12:37 apt-mirror
权限是 apt-mirror:apt-mirror
修改为当前用户权限 sudo chown
这里
修改目录权限：sudo chmod 777 -R /var/spool/apt-mirror
再运行 apt-mirror , 开始下载镜像：(如果没有裁减，将下载135G)
......

对于amd64，将上面的i386都换成amd64即可。注意建立/var/spool/apt-mirror-amd64目录及子目录 mirror skel var 并设置权限。
==============================================
使用做好的镜像源。有两种方法：1 安装web服务，类似网上镜像；2 直接文件访问，简单，可放入移动硬盘
1, 安装web服务
安装apache网站服务器
sudo apt-get install apache2
缺省的网站主目录为 /var/www/html
建立镜像目录软链接
sudo ln -s /var/spool/apt-mirror-i386/mirror /var/www/html/ubuntu-mirror-i386
察看目录
ls /var/www/html/ubuntu-mirror-i386
cn.archive.ubuntu.com extras.ubuntu.com security.ubuntu.com
察看本机ip地址
ifconfig
eth0 192.168.0.101
编辑源列表 gksu gedit /etc/apt/sources.list，在http://后面加上192.168.0.101/ubuntu-mirror-i386/，如下
#deb cdrom:[Ubuntu 14.04.3 LTS _Trusty Tahr_ - Beta i386 (20150805)]/ trusty main restricted

deb-src http://192.168.0.101/ubuntu-mirror-i386/extras.ubuntu.com/ubuntu trusty main
保存，然后执行
sudo apt-get update 更新源列表
测试，安装dia图表制作软件
sudo apt-get install dia
下载7M多软件包1秒完成。
2 直接文件访问
如果不想安装web服务，可以直接文件访问镜像。
修改 /etc/apt/sources.list
将http://192.168.0.101/ubuntu-mirror-i386/全部替换为file:///var/spool/apt-mirror-i386/mirror/即可
保存，然后执行
sudo apt-get update 更新源列表
如果镜像在移动磁盘，路径替换为移动磁盘镜像就行了
==================================================================
apt-mirror可以随时ctrl+c退出，重新开始。利用空闲时间建立的ubuntu镜像，显著减少了安装软件包的下载时间，提高了效率。
对于当前以T计的磁盘容量，存储镜像早已不是问题。
