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 attrib file or directory attributes changed 属性发生变化 close_write file or directory closed, after being opened in 写入之后关闭 writeable mode close_nowrite file or directory closed, after being opened in read-only mode close file or directory closed, regardless of read/write mode open file or directory opened moved_to file or directory moved to watched directory 移动到哪里 moved_from file or directory moved from watched directory move file or directory moved to or from watched directory create file or directory created within watched directory delete file or directory deleted within watched directory delete_self file or directory was deleted unmount file system containing file or directory unmounted卸载
之后就可以和nfs共享服务器之间的实时备份
