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
BitTorrent Sync 2.3 (239)
Usage:
btsync [ options ... ]
Options:
--help Print this message
Use a configuration file
Storage path for identity and license
Creates user identity
Apply owner license
--nodaemon Do not daemonize
--dump-sample-config Print a sample configuration file
Set log file
Set the webui listening interface
--generate-secret Generate a read/write key
--get-ro-secret <r/w key> Get the read-only key associated to a read/write key
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。
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。
