1、安装工具
--inotify

wget https://github.com/rvoicilas/inotify-tools/archive/3.20.1.tar.gz
tar -zxvf inotify-tools-3.20.1.tar.gz
cd inotify-tools-3.20.1
./configure --prefix=/usr/local/inotify
make && make install

--rsync

下载:http://rsync.samba.org/

tar -zxvf rsync-3.1.0.tar.gz
cd rsync-3.1.0
./configure --prefix=/usr/local/rsync
make && make install

2、编写运行脚本：
[root@192.168.1.1 script]$ vi monitor_dircharge.sh

#!/bin/sh
## -------------------------------------------------

## @监控目录状态，有变化后触发rsync同步
## -------------------------------------------------

srcdir="/data"
/usr/local/inotify/bin/inotifywait -mrq --timefmt '%d/%m/%y-%H:%M' --format '%T%w%f' -e modify,delete,create,attrib,move ${srcdir} | while read file
do
rsync -rlptDvzHS --delete --port=9789 --password-file=/etc/rsyncd.password_client /data/ root@192.168.1.2::Server/data/
done

3、启动脚本

nohup sudo sh /data/script/monitor_dircharge.sh >> /tmp/inotify.log 2>&1 &

4、添加开机启动

echo 'nohup sudo sh /data/script/monitor_dircharge.sh >> /tmp/inotify.log 2>&1 &' >> /etc/rc.local
