ubuntu 下搭建BT下载服务器

简介
使用 bittorrent + nginx + 脚本实现自动化的BT服务端
目录：/data
文件目录：/data/resource
web目录：/data/wwwroot
域名：
track.xxx.com # track 服务域名
bt.xxx.com #bt 的web服务域名

第一步、下载bt服务端

apt install bittorrent

安装完成后，会有如下程序列表

btcompletedir            
btcompletedir.bittorrent
btdownloadcurses
btdownloadcurses.bittorrent
btdownloadheadless
btdownloadheadless.bittorrent
btlaunchmany
btlaunchmany.bittorrent
btlaunchmanycurses
btlaunchmanycurses.bittorrent
btmakemetafile    # bt下载服务
btmakemetafile.bittorrent
btreannounce
btreannounce.bittorrent
btrename
btrename.bittorrent
btshowmetainfo
btshowmetainfo.bittorrent
bttrack    # tracker 服务
bttrack.bittorrent

第二步、开启Tracker服务

# 开启track服务的目的在于，跟踪种子信息
bttrack --port 26001 --dfile dstate>/dev/null 2>&1 &

第三步、安装/配置nginx

apt install nginx

vim /etc/nginx/conf.d/bt.conf

server {
        listen 80;
        server_name bt.xxx.com;
        root /data/wwwroot;
        index index.html index.htm;

        location / {
                autoindex on;
                autoindex_exact_size off;
                autoindex_localtime on;
                try_files $uri $uri/ =404;
        }
}

#重启使配置生效
service nginx restart

第四步、启动/测试下载服务

#制作种子
btmakemetafile /data/wget http://track.xxx.com:26001/announce

#启动种子下载服务
btdownloadheadless --url http://bt.xxx.com/wget.torrent --saveas /data/resource/wget
#下载服务启动后会读取文件完成后提示 percent done:   100 并不断刷新


#此时下载 http://bt.xxx.com/wget.torrent 在客户端进行下载即可正常下载

第五步、脚本化处理

#!/bin/bash

BT_BIN="/usr/bin"

# track 配置
TRACK_PORT=6969
TRACK_DFILE_PATH="/data/dstate"
TRACK_LOG_FILE_PATH="/data/logs/track.log"

# 资源文件夹
RESOURCE_DIR="/data/resource"
RESOURCE_LOG_FILE_PATH="/data/logs/resource.log"

# 种子配置
DOMAIN="http://track.xxx.com:6969/announce"
BTSEED_DIR=/data/wwwroot

track_start() {
	${BT_BIN}/bttrack --port ${TRACK_PORT} --dfile ${TRACK_DFILE_PATH}>${TRACK_LOG_FILE_PATH} 2>&1 &	
}

download_start() {
	${BT_BIN}/btlaunchmany ${RESOURCE_DIR}>${RESOURCE_LOG_FILE_PATH} 2>&1 &
}

update_torrent() {
	NUMBER=`ls $RESOURCE_DIR |grep -v resume |grep -v metainfo | grep -v ".torrent"|wc -l`
	CONTENT=`ls $RESOURCE_DIR |grep -v resume |grep -v metainfo | grep -v ".torrent" > /tmp/1.txt`
	for (( i=1; i<=$NUMBER; i=i+1 )) 
	do
		FILE=`sed -n "$i"p /tmp/1.txt`
		if [ ! -f $BTSEED_DIR/$FILE.torrent ] ;then
			${BT_BIN}/btmakemetafile ${RESOURCE_DIR}/$FILE ${DOMAIN}
		
			/bin/cp $RESOURCE_DIR/$FILE.torrent $BTSEED_DIR
		fi
	done
}

case "$1" in
	up)
		update_torrent
		;;
	start)
		track_start
		download_start
		;;
	stop)
		ps -ef |grep /usr/bin/bt | grep -v "grep" |awk '{print $2}'| xargs kill -9
		;;
