Centos制作BT种子并获取BT种子信息

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()
