aria2 是一款非常流行的开源下载工具，可以用来下载各种协议文件，包括 BT 种子与磁力链接.
安装并配置Aria2
首先，安装：
apt-get install aria2创建 Aria2 的配置文件夹：
mkdir /etc/aria2创建 session 和配置文件：
touch /etc/aria2/aria2.session
touch /etc/aria2/aria2.conf编辑 /etc/aria2/aria2.conf：
vim /etc/aria2/aria2.conf完整配置文件：
然后执行：
aria2c --conf-path=/etc/aria2/aria2.conf -D没有任何提示则表示成功。接下来添加开机自启：
touch /etc/init.d/aria2c
nano /etc/init.d/aria2c添加：
#!/bin/sh
### BEGIN INIT INFO
# Provides: aria2
# Required-Start: remotefsnetwork
# Required-Stop: remotefsnetwork
# Default-Start: 2 3 4 5
# Default-Stop: 0 1 6
# Short-Description: Aria2 Downloader
### END INIT INFO
case "$1" in
start)
echo -n "Starting aria2c"
sudo aria2c --conf-path=/etc/aria2/aria2.conf -D
;;
stop)
echo -n "Shutting down aria2c "
killall aria2c
;;
restart)
# killall aria2c
sudo aria2c --conf-path=/etc/aria2/aria2.conf -D
;;
esac
exit执行：
chmod +x /etc/init.d/aria2c关于添加Bt-crack
这是一份在 GitHub 上的 trackers 列表：[Github]（https://github.com/ngosang/trackerslist/blob/master/trackers_all.txt）
在初次使用 aria2 时会发现始终无速度的问题，听说只需要添加这份trackers 列表进 aria2 就能明显的提高下载速度。但是aira2需要以逗号隔开trackers，故写下如下Python脚本。
with open('/home/pi/Documents/btcrackall.txt') as f:
while True:
line = f.readline()
if not line:break
if line != '\n':
liness = line.rstrip('\n')
print(liness,end=",")以下是的出的结果

安装uGet
sudo apt-get install uget打开uget并最大化，点击edit->setting
点击插件，选aria2，注意输入token，点击ok。
如果出现不能下载的问题，如uGet弹出Error occourred when downloading。可能是aria2的问题，在terminal中执行aria2c --daemon --enable-rpc=true即可 。
下载迅雷链接
需要多进行一步链接转换。
迅雷下载协议是经过加密的,如：
thunder://QUFodHRwOi8vd3d3LmNub3N3aWtpLmNvbS93cC1jb250ZW50L3RoZW1lcy9tb25vY2hyb21lL2ltZy9sb2dvLmdpZlpa直接在Linux下面是没有办法下载的。
在ubuntu中，可在终端下使用echo url|base64 -d 来显示解密后的地址。如（URL为迅雷链接去掉开头）：
echo
QUFodHRwOi8vd3d3LmNub3N3aWtpLmNvbS93cC1jb250ZW50L3RoZW1lcy9tb25vY2hyb21lL2ltZy9sb2dvLmdpZlpa
|base64 -d显示结果是：
AAhttp://www.cnoswiki.com/wp-content/themes/monochrome/img/logo.gifZZ然后去除开头的AA和结尾的ZZ既是解密后的地址：
http://www.cnoswiki.com/wp-content/themes/monochrome/img/logo.gif拿到解密后的地址后，就可以使用uGet下载工具进行下载！
