使用BitTorrent-Sync实现双机文件双向同步

安装

直接从官网下载相应的安装包，为了在Linux服务器上安装，使用的是Linux x64版本BitTorrent-Sync_x64.tar.gz。

然后解压到指定的文件夹，即可执行程序。

sudo mkdir -p /usr/local/btsync

sudo chown shenfeng /usr/local/btsync

tar -zxvf BitTorrent-Sync_x64.tar.gz -C /usr/local/btsync/

进入解压后的目录，可以看到3个文件，其中btsync为可执行文件。

$ ls

btsync  LICENSE.TXT  README

执行--help可以查看帮助信息

 ./btsync --help

配置

编写启动脚本。

$ sudo vi /etc/init.d/btsync

#!/bin/sh

#

# description: starts and stops the btsync client

CONF=/usr/local/btsync/btsync.cfg

PROC=/usr/local/btsync/btsync

PIDFILE=/usr/local/btsync/btsync.pid

start() {

  PID1=$(pidof btsync)

  if [ -z ${PID1} ]; then

    echo -n "Starting BitTorrent Sync: "

    ${PROC} --config ${CONF}

  else

    echo "BitTorrent Sync is already running at pid:${PID1}"

  fi

  return $?

}

stop() {

  echo -n "Stopping BitTorrent Sync: "

  PID1=$(pidof btsync)

  if [ ! -z ${PID1} ]; then

    kill -9 ${PID1}

    echo "OK"

  else

    echo "Failed"

  fi

  return $?

}

status() {

  PID1=$(pidof btsync)

  PID2=$(cat ${PIDFILE})

  echo -n "Checking BitTorrent Sync: "

  if [ ! -z ${PID1} ] && [ "${PID1}" -eq "${PID2}" ]; then

    echo "OK"

  else

    echo "Failed"

  fi

  return $?

}

case "$1" in

  start)

   start

  ;;

  stop)

    stop

  ;;

  restart)

    stop

    sleep 1

    start

  ;;

  status)

    status

  ;;

  *)

    echo $"Usage: $0 {start|stop|restart|status}"

    exit 2

esac

编写启动配置文件

{

  "device_name": "vm_2",

  "listening_port" : 8889, // 0 - randomize port

  "check_for_updates" : false,

  "use_upnp" : false,

  "storage_path" : "/usr/local/btsync",

  "pid_file" : "/usr/local/btsync/btsync.pid",

  "download_limit" : 0, // 0 - no limit

  "upload_limit" : 0,

  "webui" :

  {

    "listen" : "0.0.0.0:8888",

    "login" : "admin",

    "password" : "btsync"

  }

  ,

  "folder_rescan_interval" : 1,

  "lan_encrypt_data" : false,

}

启动程序，通过web页面进行登录和后续配置。

$ /etc/init.d/btsync start

Starting BitTorrent Sync: By using this application, you agree to our Privacy Policy, Terms of Use and End User License Agreement.

Webui is listening on 0.0.0.0:8888

BitTorrent Sync forked to background. pid = 15002

在浏览器页面登录控制页面，即服务器IP+8888端口。

使用配置文件中的账号密码进行登录。

在启动一台主机上，点击左上角的Add Folder按钮，增加需要同步的目录。

确认打开目录后，会生成该目录的Key，因为需要双向同步，那么选择READ+WRITE的Key。

登录第二台服务器，登录后，点击Add Folder的第三个选项。填入上面复制的Key之后，选择本地用于同步的目录就可以进行同步了。
