rsync + lnotify 实现数据的实时同步更新

1.检查rsync是否安装

rpm -q rsync

2.定义配置文件/etc/rsyncd.conf

 

uid=sunliyan
gid=sunliyan
user chroot=no
max connections=200
timeout=600
pid file=/var/run/rsyncd.pid
lock file=/var/run/rsyncd.lock
log file=/var/log/rsyncd.log
[backup]
path=/backup/
ignore errors
read only=no
list=no
hosts allow=192.168.10.0/255.255.255.0
auth users=sunliyan
secrets file=/etc/rsyncd.password

3.启动服务端rsync服务

vim /etc/xinetd.d/rsync

 

service rsync
{
    disable = no
    flags           = IPv6
    socket_type     = stream
    wait            = no
    user            = root
    server          = /usr/bin/rsync
    server_args     = --daemon
    log_on_failure  += USERID
}

service xinetd restart

4.创建相关目录

mkdir /backup

chmod -R 777 /backup

echo "sunliyan:password" > /etc/rsyncd.password

chmod  600 /etc/rsyncd.password

5.客户端配置如下

echo "password" > /etc/rsyncd.password

chmod  600 /etc/rsyncd.password

6.客户端安装lnotify软件

cd /usr/local/src

tar zxfv inotify-tools-3.14.tar.gz

cd inotify-tools-3.14

./configure && make && make install

7.编写监控脚本

 

#!/bin/bash
src=/backup/
des=backup
ip=192.168.10.1
/usr/local/bin/inotifywait -mrq --timefmt '% d/% m/% y % H:% M' --format '% T % w% f' -e modify,delete,create,attrib $src | while read file
    do
       rsync -vzrtopg --delete --progress $src sunliyan@$ip::$des --password-file=/etc/rsyncd.password &&
       echo "$src was  rsynced"
    done

8.将脚本放入后台

nohup sh/root/rsync.sh &
