A机器上的操作：192.168.200.101：

[root@crushlinux1 ~]# cat /proc/sys/fs/inotify/max_queued_events
16384
[root@crushlinux1 ~]# cat /proc/sys/fs/inotify/max_user_instances
128
[root@crushlinux1 ~]# cat /proc/sys/fs/inotify/max_user_watches
8192
[root@crushlinux1 ~]# vi /etc/sysctl.conf
fs.inotify.max_queued_events = 16384
fs.inotify.max_user_instances = 1024             
fs.inotify.max_user_watches = 1048576
[root@crushlinux1 ~]# sysctl -p
[root@crushlinux1 ~]# tar zxvf inotify-tools-3.14.tar.gz
root@crushlinux1 ~]# cd inotify-tools-3.14
[root@crushlinux1 inotify-tools-3.14]# ./configure
[root@crushlinux1 inotify-tools-3.14]# make && make install
[root@crushlinux1 inotify-tools-3.14]# inotifywait -mrq -e modify,create,move,delete /var/www/html/
/var/www/html/
/var/www/html/ CREATE,ISDIR a
/var/www/html/ CREATE,ISDIR b
另一个终端：
[root@crushlinux1 ~]# mkdir /var/www/html/a

$INOTIFY_CMD | while read DIRECTORY EVENT FILE
do
        if [ $(pgrep rsync | wc -l) -le 0 ]
        then
                $RSYNC_CMD
        fi
done
[root@crushlinux1 ~]# chmod +x inotify_rsync.sh
