BT服务器的安装和配置

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，所以不会像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下载首先在第一个共享端（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，所以造成使用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/
[root@jsb-ylw-5024 tarbag]# cd ../software/ActivePython-2.7.0.2-linux-x86_64/
[root@jsb-ylw-5024 ActivePython-2.7.0.2-linux-x86_64]# ./install.sh
 Enter directory in which to install ActivePython. Leave blank and
press 'Enter' to use the default [/opt/ActivePython-2.7].
Install directory: /usr/local/python

ActivePython has been successfully installed to:

    /usr/local/python

[root@jsb-ylw-5024 ActivePython-2.7.0.2-linux-x86_64]# ls /usr/local/python/
bin doc include lib share

[root@jsb-ylw-5024 ~]# env |grep PATH
PATH=/root/bin:/usr/local/mysql/bin:/usr/local/python/bin/:/usr/local/rlwarp/bin/:/usr/local/java/bin:/usr/kerberos/sbin:/usr/kerberos/bin:/usr/local/sbin:/usr/local/bin:/sbin:/

bin:/usr/sbin:/usr/bin

二：下载,安装BitTorrent

[root@jsb-ylw-5024 ~]# cd /usr/local/src/tarbag/
[root@jsb-ylw-5024 tarbag]# wgethttp://download.bittorrent.com/dl/archive/BitTorrent-3.9.1.tar.gz
[root@jsb-ylw-5024 tarbag]# tar -zxvf BitTorrent-3.9.1.tar.gz -C ../software
 [root@jsb-ylw-5024 tarbag]# cd ../software/BitTorrent-3.9.1
 [root@jsb-ylw-5024 BitTorrent-3.9.1]# python2.7 setup.py install
[root@jsb-ylw-5024 BitTorrent-3.9.1]# ls /usr/local/python/bin/bt*
/usr/local/python/bin/btdownloadcurses.py    /usr/local/python/bin/btlaunchmany.py      /usr/local/python/bin/btrename.py
/usr/local/python/bin/btdownloadgui.py       /usr/local/python/bin/btmaketorrentgui.py /usr/local/python/bin/btshowmetainfo.py
/usr/local/python/bin/btdownloadheadless.py /usr/local/python/bin/btmaketorrent.py     /usr/local/python/bin/bttest.py
/usr/local/python/bin/btlaunchmanycurses.py /usr/local/python/bin/btreannounce.py      /usr/local/python/bin/bttrack.py

三：启动BT

[root@jsb-ylw-5024 ~]# /usr/local/python/bin/python2.7 /usr/local/python/bin/bttrack.py --port 6969 --dfile /tmp/bttrack.log &
[1] 22603
[root@jsb-ylw-5024 ~]# ps -ef |grep python
root     22670 22614 1 15:32 pts/1    00:00:00 /usr/local/python/bin/python2.7 /usr/local/python/bin/bttrack.py --port 6969 --dfile /tmp/bttrack.log
root     22679 22614 0 15:32 pts/1    00:00:00 grep python
[root@jsb-ylw-5024 ~]# netstat -ntpl |grep 6969
tcp        0      0 0.0.0.0:6969                0.0.0.0:*                   LISTEN      22670/python2.7

四：制作BT种子
[root@jsb-ylw-5024 ~]# /usr/local/python/bin/btmaketorrent.pyhttp://192.168.50.24:6969/announce /root/resoucre/ubuntu.pdf
 [root@jsb-ylw-5024 ~]# mv /root/resoucre/ubuntu.pdf.torrent /www/

[root@jsb-ylw-5024 ~]# ln /root/resoucre/ubuntu.pdf /www/
[root@jsb-ylw-5024 ~]# ll /root/resoucre/ubuntu.pdf
 -rwxr-xr-x 2 root root 60334729 10-25 15:36 /root/resoucre/ubuntu.pdf


[root@jsb-ylw-5024 ~]# /usr/local/python/bin/btlaunchmany.py --data_dir /root/resoucre/ --torrent_dir /www > /dev/null 2>&1 &
[2] 23354

[root@jsb-ylw-5024 ~]# ps -ef |grep python |grep -v 'grep'
root     22670 22614 0 15:32 pts/1    00:00:00 /usr/local/python/bin/python2.7 /usr/local/python/bin/bttrack.py --port 6969 --dfile /tmp/bttrack.log
root     23354 22614 0 15:42 pts/1    00:00:00 /usr/local/python/bin/python2.7 /usr/local/python/bin/btlaunchmany.py --data_dir /root/resoucre/ --torrent_dir /www

五：下载测试

 

六：自动生成种子脚本

[root@jsb-ylw-5024 ~]# cat auto_bt_seed.sh
 #!/bin/bash
#function: auto generate bt seed ...
#author: lw.yang
#version: V.1.0


MAKEBT=/usr/local/python/bin/btmaketorrent.py
DOMAIN=http://192.168.50.24:6969/announce
RESOURCE_DIR=/root/resource
BTSEED_DIR=/www
NUMBER=`ls $RESOURCE_DIR |grep -v resume |grep -v metainfo|wc -l`
CONTENT=`ls $RESOURCE_DIR |grep -v resume |grep -v metainfo > /tmp/1.txt`

for (( i=1; i<=$NUMBER; ii=i+1 ))

do

FILE=`sed -n "$i"p /tmp/1.txt`

if [ ! -f $BTSEED_DIR/$FILE.torrent ] ;then

$MAKEBT $DOMAIN $RESOURCE_DIR/$FILE

ln $RESOURCE_DIR/$FILE $BTSEED_DIR

/bin/mv $RESOURCE_DIR/$FILE.torrent $BTSEED_DIR

fi
done
