Linux内核从2.6.13开始支持inotify。
Inotify可以监控文件系统的读取，修改，创建等状态。（更多信息请参考网上资料）
通过Rsync+Inotify（inotifywati）可以实现文件的批量分发功能。
1 查看linux是否支持inotify
a) 内核至少是2.6.13
uname -r
b) 存在/usr/include/sys/inotify.h，说明支持
c) 查看/proc/sys/fs/inotify/

-rw-r--r-- 1 root root 0 Jul 17 10:28max_queued_events
-rw-r--r-- 1 root root 0 Jul 17 10:28max_user_instances
-rw-r--r-- 1 root root 0 Jul 17 10:28max_user_watches
有以上3个文件说明支持
2 下载inotify-tools-3.13.tar并安装
tar zxvf inotify-tools-3.13.tar.gz
cd inotify-tools-3.13
./configure
make&&make install
安装完成后会在/usr/local/bin/下生成2个文件：
ls -l /usr/local/bin/inotify*
-rwxr-xr-x 1 root root 38582 Jul 17 10:37/usr/local/bin/inotifywait
-rwxr-xr-x 1 root root 40353 Jul 17 10:37/usr/local/bin/inotifywatch
3 分发服务器server脚本

rsync -az $Src [email protected]$Host02::$Dst02--password-file=/etc/rsync.password
done
4 web01/02服务器将rsync配置rsync-daemon模式（参考http://szcat.blog.51cto.com/665775/1826733）
5 web01/02服务器rsyncd.conf配置文件
