BT是BitTorrent（比特流）的简称,BT的特点是用户下载的同时,也在为其它用户提供上传, 不会像FTP服务器那样随着用户数的增加而导致下载速度降低.恰恰相反,对于BT下载而言,下载的人越多速度越快. BT下载 在第一个共享端（或称为Downloader）把一个文件分成N个部分,A用户可以从Downloader上随机下载第M个部分,B用户可以在Downloader服务器随机下载第Ｋ个部分.而A用户的BT客户端下载程序会根据情况从B用户下载第Ｋ个部分,同样的,B用户也可以从A用户下载第M个部分,通过这种方式减轻服务器端负荷,加快用户的下载速度, 例如,C用户直接从服务器下载,速度可能只有几Kbps,而从A、B用户处下载,速度将快很多.用户在下载的同时,也在上传文件,在享受别人提供下载服务的同时,每个用户也同时在上载并贡献自己的带宽,造成使用BT下载服务的人越多,大家的速度就越快.BT下载的优越性就在这里体现,下面简要介绍下BitTorrent的安装,感谢胡帅哥的精彩分享…
一：安装Python
[root@jsb-ylw-5024 ~]# cd /usr/local/src/tarbag/
[root@jsb-ylw-5024 tarbag]# wgethttp://downloads.activestate.com/ActivePython/releases/2.7.0.2/ActivePython-2.7.0.2-linux-x86_64.tar.gz
[root@jsb-ylw-5024 tarbag]# tar -zxvf ActivePython-2.7.0.2-linux-x86_64.tar.gz -C ../software/
