inotify工具安裝配置

1、安裝

1）  從內核和目錄裏面查看是否支持inotify

[root@nfs01 ~]# uname -r

2.6.32-573.el6.x86_64

[root@nfs01 ~]# ls -l /proc/sys/fs/inotify/    -→主要查看下面有沒有三個目錄

總用量 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）檢查是否有安裝inotify 若是沒有就安裝

rpm -qa inotify-tools

沒有就先安裝epol源

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

以後安裝

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

2、參數講解、

[root@nfs01 ~]# which inotifywait

/usr/bin/inotifywait

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

 

r ：遞歸查詢目錄

q：打印不多的信息，僅僅打印監控事件的信息  安靜狀態

m：始終保持事件監聽狀態

excluder#排除文件或者目錄的時候不區分大小寫

timefmt：指定時間輸出的格式

d ：後臺運行

-e： 事件 裏面有不少方法

 

下面是事件參數
