让内网Ubuntu系统更新更轻松
还是起了原来的标题名称，今天在找内网Ubuntu系统更新的方案时，看到了网站上的一篇帖子，很是兴奋。可拿来一看却发现这个apt-proxy的东东已经不在ubuntu12.04(LTS)的发布版本里了，看来这篇帖子又是有点跟不上潮流的那种。查了一下资料，目前发布版本中提供了approx。官方的描述如下：
Approx is an HTTP-based proxy server for Debian-style package archives. Itfetches files from remote repositories on demand, and caches them for localuse.
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 isdownloaded from a remote site only once, regardless of how many local clientsinstall it. The approx cache typically requires a few gigabytes of diskspace.
Approx also simplifies the administration of client machines: repositorylocations need only be changed in approx's configuration file, not in everyclient's /etc/apt/sources.list file.
Approx can be used as a replacement for apt-proxy, with no need to modifyclients' /etc/apt/sources.list files, or as an alternative to apt-cacher.
approx看来确实是替代了apt-proxy，在10.04之后就不再提供apt-proxy了。
approx部署起来也是简单至极，首先部署approx:
sudo apt-get install approx
通过下边的指令获取当前/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，添加如下内容
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 ]
重新启动之后，服务就已经在9999端口运行了。
在客户端的配置，其实就是把客户端的/etc/apt/sources.list文件变更为你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 universemultiverse
deb-src http://approx:9999/ubuntu/ precise-backports main restricteduniverse 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
其他地址就可以删除掉了。剩下的就是sudo apt-get update ~~~
