讓內網Ubuntu系統更新更輕松

   還是起了原來的標題名稱,今天在找內網Ubuntu系統更新的方案時,看到了網站上的一篇帖子,很是興奮。可拿來一看卻發現這個apt-proxy的東東已經不在ubuntu 12.04(LTS)的發布版本裡了,看來這篇帖子又是有點跟不上潮流的那種。查了一下資料,目前發布版本中提供了approx。官方的描述如下:

  Approx is an HTTP-based proxy server for Debian-style package archives. It fetches files from remote repositories on demand, and caches them for local use.

  Approx saves time and network bandwidth if you need to install or upgrade .deb packages for a number of machines on a local network. Each package is downloaded from a remote site only once, regardless of how many local clients install it. The approx cache typically requires a few gigabytes of disk space.

  Approx also simplifies the administration of client machines: repository locations need only be changed in approx's configuration file, not in every client's /etc/apt/sources.list file.

  Approx can be used as a replacement for apt-proxy, with no need to modify clients' /etc/apt/sources.list files, or as an alternative to apt-cacher.

  approx看來確實是替代了apt-proxy,在10.04之後就不再提供apt-proxy了。

  approx部署起來也是簡單至極,首先部署approx:

  sudo apt-get install approx

  通過下邊的指令獲取當前/etc/apt/sources.list中的更新地址

  $ grep -E "^[^#]" sources.list | cut -d " " -f2 | uniq

  http://au.archive.ubuntu.com/ubuntu/

  http://security.ubuntu.com/ubuntu

  配置/etc/approx/approx.conf文件,添加如下內容

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

  ubuntu-extras http://extras.ubuntu.com/ubuntu

  ubuntu-partner http://archive.canonical.com/ubuntu

  ubuntu-security http://security.ubuntu.com/ubuntu

  $ sudo /etc/init.d/openbsd-inetd restart

  * Restarting internet superserver inetd [ OK ]

  重新啟動之後,服務就已經在9999端口運行了。

  在客戶端的配置,其實就是把客戶端的/etc/apt/sources.list文件變更為你approx的地址就可以了:

  deb http://approx:9999/ubuntu/ precise main restricted

  deb-src http://approx:9999/ubuntu/ precise main restricted

  deb http://approx:9999/ubuntu/ precise-updates main restricted

  deb-src http://approx:9999/ubuntu/ precise-updates main restricted

  deb http://approx:9999/ubuntu/ precise universe

  deb-src http://approx:9999/ubuntu/ precise universe

  deb http://approx:9999/ubuntu/ precise-updates universe

  deb-src http://approx:9999/ubuntu/ precise-updates universe

  deb http://approx:9999/ubuntu/ precise multiverse

  deb-src http://approx:9999/ubuntu/ precise multiverse

  deb http://approx:9999/ubuntu/ precise-updates multiverse

  deb-src http://approx:9999/ubuntu/ precise-updates multiverse

  deb http://approx:9999/ubuntu/ precise-backports main restricted universe multiverse

  deb-src http://approx:9999/ubuntu/ precise-backports main restricted universe multiverse

  deb http://approx:9999/ubuntu precise-security main restricted

  deb-src http://approx:9999/ubuntu precise-security main restricted

  deb http://approx:9999/ubuntu precise-security universe

  deb-src http://approx:9999/ubuntu precise-security universe

  deb http://approx:9999/ubuntu precise-security multiverse

  deb-src http://approx:9999/ubuntu precise-security multiverse

  其他地址就可以刪除掉了。剩下的就是sudo apt-get update ~~~
