Ubuntu12.04搭建自有源   其实，这个工作比较简单，主要两步：apt-mirror和apache。(这里的系统是ubuntu12.04)   1、apt-mirror   1.1 安装   一如既往地简单，直接sudo apt-get install apt-mirror即可。   1.2 配置apt-mirror   $ sudo vim /etc/apt/mirror.list   [plain]  ############# 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  <running host architecture>   # set postmirror_script $var_path/postmirror.sh   # set run_postmirror 0   set nthreads     20     set _tilde 0   #   ############# end config ##############      deb http://archive.ubuntu.com/ubuntu precise main restricted universe multiverse   deb http://archive.ubuntu.com/ubuntu precise-security main restricted universe multiverse   deb http://archive.ubuntu.com/ubuntu precise-updates main restricted universe multiverse   #deb http://archive.ubuntu.com/ubuntu precise-proposed main restricted universe multiverse   #deb http://archive.ubuntu.com/ubuntu precise-backports main restricted universe multiverse      deb-src http://archive.ubuntu.com/ubuntu precise main restricted universe multiverse   deb-src http://archive.ubuntu.com/ubuntu precise-security main restricted universe multiverse   deb-src http://archive.ubuntu.com/ubuntu precise-updates main restricted universe multiverse   #deb-src http://archive.ubuntu.com/ubuntu precise-proposed main restricted universe multiverse   #deb-src http://archive.ubuntu.com/ubuntu precise-backports main restricted universe multiverse      clean http://archive.ubuntu.com/ubuntu   将其修改为对自己比较快的源(这里用ustc的)： [plain]  ############ 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  <running host architecture>   #set postmirror_script $var_path/postmirror.sh   #set run_postmirror 0   set nthreads     20     set _tilde 0   #   ############# end config ##############      #precise 64bit Mirror   deb-amd64 http://mirrors.ustc.edu.cn/ubuntu precise main restricted universe multiverse   deb-amd64 http://mirrors.ustc.edu.cn/ubuntu precise-security main restricted universe multiverse   deb-amd64 http://mirrors.ustc.edu.cn/ubuntu precise-updates main restricted universe multiverse   deb-amd64 http://mirrors.ustc.edu.cn/ubuntu precise-proposed main restricted universe multiverse   deb-amd64 http://mirrors.ustc.edu.cn/ubuntu precise-backports main restricted universe multiverse      #precise 32bit Mirror   deb-i386 http://mirrors.ustc.edu.cn/ubuntu precise main restricted universe multiverse   deb-i386 http://mirrors.ustc.edu.cn/ubuntu precise-security main restricted universe multiverse   deb-i386 http://mirrors.ustc.edu.cn/ubuntu precise-updates main restricted universe multiverse   deb-i386 http://mirrors.ustc.edu.cn/ubuntu precise-proposed main restricted universe multiverse   deb-i386 http://mirrors.ustc.edu.cn/ubuntu precise-backports main restricted universe multiverse      deb-src http://mirrors.ustc.edu.cn/ubuntu precise main restricted universe multiverse   deb-src http://mirrors.ustc.edu.cn/ubuntu precise-security main restricted universe multiverse   deb-src http://mirrors.ustc.edu.cn/ubuntu precise-updates main restricted universe multiverse   deb-src http://mirrors.ustc.edu.cn/ubuntu precise-proposed main restricted universe multiverse   deb-src http://mirrors.ustc.edu.cn/ubuntu precise-backports main restricted universe multiverse      clean http://mirrors.ustc.edu.cn/ubuntu   1.3 apt-mirror同步源   用sudo apt-mirror命令开始同步源即可。   [plain]  $ sudo apt-mirror   Downloading 140 index files using 20 threads...   Begin time: Fri Nov  1 17:23:49 2013   [20]...

See above output for any possible errors.   2、apache2   2.1 安装   sudo apt-get install apache2   2.2 配置   apache2的配置，这里就不班门弄斧了。反正我是直接在网上搜的帖子，方法很简单。   [plain]  (1) 进入/var/www目录   cd /var/www   (2) 创建一个指向apt-mirror的mirror存放路径的软链接，这里命名为ubuntu   $ ln -s /var/spool/apt-mirror/mirror/mirrors.ustc.edu.cn/ubuntu ubuntu   到这里，就可以在浏览器地址栏输入“202.xxx.xxx.xxx/ubuntu”来访问该源目录了。 3、使用源   为了使用该源之需要修改/etc/apt/source.list文件:   [plain]  比如原来用的是ustc的源，source.list文件如下：   deb http://mirrors.ustc.edu.cn/ubuntu/ precise main restricted universe multiverse   deb http://mirrors.ustc.edu.cn/ubuntu/ precise-security main restricted universe multiverse   deb http://mirrors.ustc.edu.cn/ubuntu/ precise-updates main restricted universe multiverse   deb http://mirrors.ustc.edu.cn/ubuntu/ precise-proposed main restricted universe multiverse   deb http://mirrors.ustc.edu.cn/ubuntu/ precise-backports main restricted universe multiverse   deb-src http://mirrors.ustc.edu.cn/ubuntu/ precise main restricted universe multiverse   deb-src http://mirrors.ustc.edu.cn/ubuntu/ precise-security main restricted universe multiverse   deb-src http://mirrors.ustc.edu.cn/ubuntu/ precise-updates main restricted universe multiverse   deb-src http://mirrors.ustc.edu.cn/ubuntu/ precise-proposed main restricted universe multiverse   deb-src http://mirrors.ustc.edu.cn/ubuntu/ precise-backports main restricted universe multiverse   现在想改成，我们刚刚搭建好的源，只需在vim中用一个命令":%s/mirrors.ustc.edu.cn/202.xxx.xxx.xxx/g"，即可将source.list修改为如下：   deb http://202.xxx.xxx.xxx/ubuntu/ precise main restricted universe multiverse   deb http://202.xxx.xxx.xxx/ubuntu/ precise-security main restricted universe multiverse   deb http://202.xxx.xxx.xxx/ubuntu/ precise-updates main restricted universe multiverse   deb http://202.xxx.xxx.xxx/ubuntu/ precise-proposed main restricted universe multiverse   deb http://202.xxx.xxx.xxx/ubuntu/ precise-backports main restricted universe multiverse   deb-src http://202.xxx.xxx.xxx/ubuntu/ precise main restricted universe multiverse   deb-src http://202.xxx.xxx.xxx/ubuntu/ precise-security main restricted universe multiverse   deb-src http://202.xxx.xxx.xxx/ubuntu/ precise-updates main restricted universe multiverse   deb-src http://202.xxx.xxx.xxx/ubuntu/ precise-proposed main restricted universe multiverse   deb-src http://202.xxx.xxx.xxx/ubuntu/ precise-backports main restricted universe multiverse   然后，sudo apt-get update就可以看到，我们搭建的似有源的确已经生效了，速度飞快
