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：
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 -a -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()
