使用BitTorrent-Sync实现双机文件双向同步 - camash

来自： http://www.cnblogs.com/shenfeng/p/btsync_on_linux.html

BitTorrent-Sync是一款基于P2P的分布式文件同步工具，简称btsync，非开源软件但免费使用。本文使用btsync实现两台服务器上的软件双向同步。

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.https://www.getsync.com/legal/privacy https://www.getsync.com/legal/terms-of-use https://www.getsync.com/legal/eula

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。
