背景介绍：
目前我们线上的前端服务器数量比较多，超过200多台，每次发布新应用的时候，都是将软件包放在一台专门的Push服务器上，再由所有的前端服务器通过rsync自动同步。但随着前端服务器的数量越来越多，Push服务器的带宽已经成为了瓶颈。
而BitTorrent Sync这种P2P方式的同步则是一种解决方案。同时它的跨平台支持也非常好，无论是Windows，Linux，Mac OS，甚至手机端都有相应的客户端。虽然目前尚未开源，但可以免费使用，还是很不错的。
下面，就是我们在线上的纯Linux测试环境中的安装与配置步骤：
Servers:
sc2-xdbc1,sc2-xdbc2,sc2-xdbc3
1. 下载BitTorrent Sync，在所有服务器上：
$ sudo wget http://download-lb.utorrent.com/endpoint/btsync/os/linux-glibc23-x64/track/stable -O /tmp/btsync_glibc23_64.tar.gz
$ sudo mkdir /opt/btsync
$ cd /opt/btsync
$ sudo tar xzf /tmp/btsync_glibc23_64.tar.gz
2. 创建服务管理脚本，在所有服务器上：
$ sudo vim /etc/init.d/btsync
#!/bin/sh
#
# description: starts and stops the btsync client
CONF=/opt/btsync/btsync.cfg
PROC=/opt/btsync/btsync
PIDFILE=/opt/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
$ sudo chmod +x /etc/init.d/btsync
3. 创建用于同步的目录，在所有服务器上：
$ sudo mkdir /opt/btsync_transfer
4. 创建配置文件，在sc2-xdbc1上：
[adsymp@sc2-xdbc1 btsync]$ sudo vim /opt/btsync/btsync.cfg
{
"device_name": "sc2-xdbc3",
"listening_port" : 0, // 0 - randomize port
"storage_path" : "/opt/btsync",
"pid_file" : "/opt/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" : 60,
"lan_encrypt_data" : false,
"lan_use_tcp" : true
}
5. 创建同步所需的密钥，在sc2-xdbc1上：
$ sudo /etc/init.d/btsync start
打开Web UI：http://sc2-xdbc1:8888
用户名: admin
密码: btsync
点击 “Add Folder”,
在 “Path” 中输入 “/opt/btsync_transfer”
点击 “Generate” 得到 “Secret” 为 “ALUORWDEWOLV354ZHPHFT4TSQO67JWQAN”
如下图所示：
6. 创建配置文件，在sc2-xdbc2和sc2-xdbc3上：
[adsymp@sc2-xdbc2 btsync]$ sudo vim btsync.cfg
{
"device_name": "sc2-xdbc2",
"listening_port" : 0, // 0 - randomize port
"storage_path" : "/opt/btsync",
"pid_file" : "/opt/btsync/btsync.pid",
"download_limit" : 0, // 0 - no limit
"upload_limit" : 0,
"webui" :
{
"listen" : "0.0.0.0:8888",
"login" : "admin",
"password" : "btsync"
}
,
"shared_folders" :
[
{
"secret" : "ALUORWDEWOLV354ZHPHFT4TSQO67JWQAN", // * required field
"dir" : "/opt/btsync_transfer" // * required field
}
]
,
"folder_rescan_interval" : 60,
"lan_encrypt_data" : false,
"lan_use_tcp" : true
}
[adsymp@sc2-xdbc2 btsync]$ sudo /etc/init.d/btsync start
[adsymp@sc2-xdbc3 btsync]$ sudo vim btsync.cfg
{
"device_name": "sc2-xdbc3",
"listening_port" : 0, // 0 - randomize port
"storage_path" : "/opt/btsync",
"pid_file" : "/opt/btsync/btsync.pid",
"download_limit" : 0, // 0 - no limit
"upload_limit" : 0,
"webui" :
{
"listen" : "0.0.0.0:8888",
"login" : "admin",
"password" : "btsync"
}
,
"shared_folders" :
[
{
"secret" : "ALUORWDEWOLV354ZHPHFT4TSQO67JWQAN", // * required field
"dir" : "/opt/btsync_transfer" // * required field
}
]
,
"folder_rescan_interval" : 60,
"lan_encrypt_data" : false, // Encryption is very painful in terms of speed. Disabling it for LAN to increase the speed.
"lan_use_tcp" : true
}
[adsymp@sc2-xdbc3 btsync]$ sudo /etc/init.d/btsync start
7. 在/opt/btsync_transfer中放置一些文件，就可以查看同步的状态了。
打开Web UI：http://sc2-xdbc1:8888
