Apt-fast : 用 axel 来加速 apt-get 软件安装

Ubuntugeek 上介绍了一个方法，通过一个名为 apt-fast 的脚本来让 axel 结合 apt-get 命令进行软件的安装，由于 axel 可以多线程下载软件包，这样就可以起到了加速的作用。而且整个使用过程基本与 apt-get 无异，只需要把平常的 apt-get 改为 apt-fast 就可以了，比如 sudo apt-fast install package 。

 

# 安装与使用：

先安装 axel 工具

sudo apt-get install axel

从这里下载 apt-fast.sh 脚本，把它移动到 /usr/bin 目录中同时改名为 apt-fast 。

sudo cp apt-fast.sh /usr/bin/apt-fast

最后给予可执行权限

sudo chmod +x apt-fast

 

 

apt-fast.sh

# Special thanks

# Travis/travisn000 - support for complex apt-get commands

# Allan Hoffmeister - aria2c support

# Abhishek Sharma - aria2c with proxy support

# Richard Klien - Autocompletion, Download Size Checking (made for on ubuntu, untested on other distros)

# Patrick Kramer Ruiz - suggestions - see Suggestions.txt

# Sergio Silva - test to see if axel is installed, root detection/sudo autorun

 

# Use this just like apt-get for faster package downloading.

 

# Check for proper priveliges

[ "`whoami`" = root ] || exec sudo "$0" "$@"

 

# Test if the axel is installed

if [ ! -x /usr/bin/axel ]

# If the user entered arguments contain upgrade, install, or dist-upgrade

if echo "$@" | grep -q "upgrade\|install\|dist-upgrade"; then

  echo "Working...";

 

  # Go into the directory apt-get normally puts downloaded packages

  cd /var/cache/apt/archives/;

 

  # Have apt-get print the information, including the URI's to the packages

  # Strip out the URI's, and download the packages with Axel for speediness

  # I found this regex elsewhere, showing how to manually strip package URI's you may need...thanks to whoever wrote it

  apt-get -y --print-uris $@ | egrep -o -e "(ht|f)tp://[^\']+" > apt-fast.list && cat apt-fast.list | xargs -l1 axel -a
