一、安装

1）  从内核和目录里面查看是否支持inotify

[root@nfs01 ~]# uname -r

2.6.32-573.el6.x86_64

[root@nfs01 ~]# ls -l /proc/sys/fs/inotify/    -→主要查看下面有没有三个目录

总用量 0

-rw-r--r-- 1 root root 0 1月  21 13:03 max_queued_events

-rw-r--r-- 1 root root 0 1月  21 13:03 max_user_instances

-rw-r--r-- 1 root root 0 1月  21 13:03 max_user_watches

2）检查是否有安装inotify 如果没有就安装

rpm -qa inotify-tools

没有就先安装epol源

yum.repos.d]# wget -O /etc/yum.repos.d/epel.repo http://mirrors.aliyun.com/repo/epel-6.repo

之后安装

[root@nfs01 ~]# yum install inotify-tools -y

二、参数讲解、

[root@nfs01 ~]# which inotifywait

/usr/bin/inotifywait

[root@nfsserver inotify-tools]# bin/inotifywait —help

 

r ：递归查询目录

q：打印很少的信息，仅仅打印监控事件的信息  安静状态

m：始终保持事件监听状态

excluder#排除文件或者目录的时候不区分大小写

timefmt：指定时间输出的格式

d ：后台运行

-e： 事件 里面有很多方法

 

下面是事件参数

Events:

        access          file or directory contents were read   访问

        modify          file or directory contents were written  修改

        open            file or directory opened

        moved_to        file or directory moved to watched directory  移动到哪里
