DAY 36

实时复制

1）部署NFS客户端

[root@nfs01 ~]# echo 'export RSYNC_PASSWORD=oldboy' >>/etc/bashrc

[root@nfs01 ~]# source /etc/bashrc

[root@nfs01 ~]# echo $RSYNC_PASSWORD

oldboy

测试推送

[root@nfs01 ~]# rsync -avz /data [email protected]::backup/

sending incremental file list

sent 164 bytes  received 25 bytes  126.00 bytes/sec

total size is 0  speedup is 0.00

2）查看inotify支持情况

[root@nfs01 ~]# uname -r

3.10.0-957.5.1.el7.x86_64

[root@nfs01 ~]#  ls -l /proc/sys/fs/inotify/

总用量 0

-rw-r--r-- 1 root root 0 4月  19 09:45 max_queued_events 

-rw-r--r-- 1 root root 0 4月  19 09:45 max_user_instances

-rw-r--r-- 1 root root 0 4月  19 09:45 max_user_watches

3）安装inotify-tools

yum install epel-release -y

yum install inotify-tools -y

[root@nfs01 ~]# rpm -ql inotify-tools|head -2

/usr/bin/inotifywait

/usr/bin/inotifywatch

[root@nfs01 ~]# rpm -qa inotify-tools

inotify-tools-3.14-8.el7.x86_64

4)命令参数和事件知识

略

5）测试实践

inotifywait -mrq --timefmt '%d/%m/%y %H:%M' --format '%T %w%f' -e create /data
