rsync+inotify简单搭建实时同步

一、rsync环境搭建

    1、服务端

（1）、安装rsync

yum install -y rsync

（2）、编辑/etc/rsyncd.conf配置文件

uid = rsync 

gid = rsync 

use chroot = no

max connections = 200

timeout = 300

pid file = /var/run/rsyncd.pid

lock file = /var/run/rsync.lock

log file = /var/log/rsyncd.log

[data]

path = /data/

ignore errors

read only = false

list = false

hosts allow = 192.168.1.0/24

hosts deny 0.0.0.0/32

auth users = rsync_backup

secrets file = /etc/rsync.password

（3）、启动rsync,病修改文件属性

rsync --daemon

netstat -lntp  

useradd rsync -s /sbin/nologin

chown -R rsync.rsync /data

echo "rsync_backup:password" > /etc/rsync.password

chmod 600 /etc/rsync.password

    2、客户端

（1）、配置密码文件

echo "password" > /etc/rsync.password

（2）、传输文件

rsync -avz /dara rsync_backup@192.168.1.188::data 

二、inotify实现同步

（1）、安装inotify-tools

wget http://github.com/downloads/rvoicilas/inotify-tools/inotify-tools-3.14.tar.gz

tar xf inotify-tools-3.14.tar.gz

cd inotify-tools-3.14

./configure --prefix=/usr/local/inotify

make

make install

或者

yum install -y inotify-tools

（2）、编写脚本实现实时同步

脚本内容：

                   #!/bin/sh
                   rsync -az /data/ rsync_backup@192.168.1.188::data --password-file=/etc/rsync.password
                   /usr/local/inotify/bin/inotifywait -mrq --timefmt '%d%m%y %H:%M' --format '%T %w%f' -e create /data|\
                   while read line
                   do

                       rsync -az `echo $line|cut -f3 -d' '` rsync_backup@192.168.1.188::data\

                        --password-file=/etc/rsync.password

                   done

        （3）、后台运行inotify同步脚本；

                sh inotify.sh &
