1、配置当前软件源，镜像非常大，所以首先要配置一下载速度快的软件源http://fffo.blog.163.com/blog/static/2119130682014322104136601/2、安装镜像软件 并 修改镜像参数文件
1）、安装apt-mirror
sudo apt-get install apt-mirror
2）、修改mirror.list
http://www.linuxidc.com/Linux/2014-08/105415.htm
sudo gedit /etc/apt/mirror.list
文件内容如下：

############# config ##################
#
# set base_path /var/spool/apt-mirror ［镜像存放目录位置，可根据磁盘容量情况进行更改］
#
# if you change the base path you must create the directories below with write privileges
#
# 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 nthreads 3 ［下载进程，默认20，建议3］
set _tilde 0

［需要进行镜像的APT软件源地址，选择速度较快的官方源或国内源］
#deb-src http://archive.ubuntu.com/ubuntu jaunty main restricted universe multiverse
#deb-src http://archive.ubuntu.com/ubuntu jaunty-updates main restricted universe multiverse
#deb-src http://archive.ubuntu.com/ubuntu jaunty-backports main restricted universe multiverse
#deb-src http://archive.ubuntu.com/ubuntu jaunty-security main restricted universe multiverse
#deb-src http://archive.ubuntu.com/ubuntu jaunty-proposed main restricted universe multiverse
［不需要源代码，用#进行地址屏蔽］
clean http://archive.ubuntu.com/ubuntu
clean http://archive.ubuntu.org.cn/ubuntu-cn
［镜像完成后对本地镜像和软件源进行比较］

3、创建镜像根目录
mkidr /var/spool/apt-mirror
4、开始镜像（支持断点续传，任何中断都不会照成影响）
1）sudo apt-mirror
定时执行上面的命令，可以达到定时同步远程仓库的效果
2）完成镜像后进行清理多余文件
sudo /var/spool/apt-mirror/var/clean.sh
5、使用本地源
cd /etc/apt
sudo mv source.list source.list.bak
sudo vim source.list
加入如下内容
deb file:///var/spool/apt-mirror/mirror/archive.ubuntu.com/ubuntu/ jaunty main restricted universe multiverse
deb file:///var/spool/apt-mirror/mirror/archive.ubuntu.com/ubuntu/ jaunty-backports restricted universe multiverse
deb file:///var/spool/apt-mirror/mirror/archive.ubuntu.com/ubuntu/ jaunty-proposed main restricted universe multiverse
deb file:///var/spool/apt-mirror/mirror/archive.ubuntu.com/ubuntu/ jaunty-security main restricted universe multiverse
deb file:///var/spool/apt-mirror/mirror/archive.ubuntu.com/ubuntu/ jaunty-updates main restricted universe multiverse
deb file:///var/spool/apt-mirror/mirror/archive.ubuntu.org.cn/ubuntu-cn/ jaunty main restricted universe multiverse
6、发布到局域网
1）安装Apache2
sudo apt-get install apache2
2）建立符号连接，将镜像与Apache虚拟目录联系起来
sudo ln -s /var/spool/apt-mirror/mirror/archive.ubuntu.com/ubuntu/ /var/www/html/ubuntu
3）局域网中每个用户，修改sources.list文件
cd /etc/apt
sudo cp sources.list sources.list.bak
sudo vim source.list
加入如下内容
deb http://192.168.0.10/ubuntu jaunty main restricted universe multiverse
deb http://192.168.0.10/ubuntu jaunty-backports restricted universe multiverse
deb http://192.168.0.10/ubuntu jaunty-proposed main restricted universe multiverse
deb http://192.168.0.10/ubuntu jaunty-security main restricted universe multiverse
deb http://192.168.0.10/ubuntu jaunty-updates main restricted universe multiverse
deb http://192.168.0.10/ubuntu-cn jaunty main restricted universe multiverse
