最近研究了一下linux BT服务器环境的搭建，需要在linux下制作BT种子并获取BT种子信息，整理了一下这个过程：

制作BT种子软件下载地址：http://jaist.dl.sourceforge.net/project/mktorrent/mktorrent/1.0/mktorrent-1.0.tar.gz

安装：

[root@localhost src]# tar zxf mktorrent-1.0.tar.gz

[root@localhost src]# cd mktorrent-1.0

[root@localhost mktorrent-1.0]# make

[root@localhost mktorrent-1.0]# make install

[root@localhost ~]# which mktorrent

/usr/local/bin/mktorrent

需要python的bencode模块来获取BT种子信息，下载地址：https://pypi.python.org/packages/source/b/bencode/bencode-1.0.tar.gz

安装：

#tar -zxf bencode-1.0.tar.gz

#cd bencode-1.0.tar.gz

#python setup.py install

制作和验证的python脚本如下：#!/usr/bin/env python

# -*- coding: utf-8 -*-

import os, re, time, sys

import hashlib, bencode

file_name = 'bt_test.exe'

bt_source = '/data/updir/%s' % file_name

bt_name = '/data/source/%s.torrent' % file_name

if os.path.exists(bt_name):

os.remove(bt_name)

if os.path.exists(bt_source):

conm = "/usr/local/bin/mktorrent -v -p -l 18 -a http://bt1.text.cn/announce -a http://bt2.text.cn/announce -o %s %s" % (bt_name,bt_source)

res = os.popen(conm).readlines()[-1].strip()

if 'done' in res:

bt_path = {}

bt_file = open(bt_name, 'rb')

bt_info = bencode.bdecode(bt_file.read()).get('info')

bt_info_hash_hex = hashlib.sha1(bencode.bencode(bt_info)).hexdigest()

if os.path.isdir(bt_source):

bt_file_size = 0

for length in bt_info.get('files'):

bt_file_size = bt_file_size + int(length['length'])

bt_path['/'.join(length['path'])] = length['length']

else:

bt_file_size = bt_info.get('length')

bt_file_name = bt_info.get('name')

bt_path[bt_file_name]=bt_file_size

bt_file.close()

print bt_path

print "Create torrent success"

else:

print "Create torrent Error"

sys.exit()

else:

print "This source not find"

sys.exit()

file_name为做种的文件或目录名字。
