Ubuntu12.04搭建自有源
其實，這個工作比較簡單，主要兩步：apt-mirror和apache。(這裡的系統是ubuntu12.04)
1、apt-mirror
1.1 安裝
一如既往地簡單，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-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
將其修改為對自己比較快的源(這裡用ustc的)：

clean http://mirrors.ustc.edu.cn/ubuntu
1.3 apt-mirror同步源
用sudo apt-mirror命令開始同步源即可。
[plain]
$ sudo apt-mirror

這裡，要注意，有時候會碰到“No such file apt-mirror: can't open index in proceed_index_gz at /usr/bin/apt-mirror line 445.”這樣的錯誤，折騰了我一個下午。原因不怎麼清楚，不過，貌似按照上面我的流程做，至少可以避免這個錯誤。具體原因，難道和我配置文件中沒去掉注釋有關系，總之，稍詭異。
最後完成後的輸出如下：
[plain]
$ sudo apt-mirror

Run /var/spool/apt-mirror/var/clean.sh for this purpose.

2、apache2
2.1 安裝
sudo apt-get install apache2
2.2 配置
apache2的配置，這裡就不班門弄斧了。反正我是直接在網上搜的帖子，方法很簡單。
[plain]
(1) 進入/var/www目錄
cd /var/www
(2) 創建一個指向apt-mirror的mirror存放路徑的軟鏈接，這裡命名為ubuntu
$ ln -s /var/spool/apt-mirror/mirror/mirrors.ustc.edu.cn/ubuntu ubuntu
到這裡，就可以在浏覽器地址欄輸入“202.xxx.xxx.xxx/ubuntu”來訪問該源目錄了。
3、使用源
為了使用該源之需要修改/etc/apt/source.list文件:
[plain]
比如原來用的是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
現在想改成，我們剛剛搭建好的源，只需在vim中用一個命令":%s/mirrors.ustc.edu.cn/202.xxx.xxx.xxx/g"，即可將source.list修改為如下：
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
然後，sudo apt-get update就可以看到，我們搭建的似有源的確已經生效了，速度飛快
