服务端：backup_server    192.168.174.10

客户端：lamp                  192.168.174.20

一、服务端部署

①生成配置文件

vim /etc/rsyncd.conf

#Rsync server#created by yupan 15:01 2016-02-23##rsyncd.conf start##uid = rootgid = rootuse chroot = nomax connections = 2000timeout = 600pid file = /var/run/rsyncd.pidlock file = /var/run/rsync.locklog file = /var/log/rsyncd.logignore errorsread only = falselist = falsehosts allow = 192.168.174.0/24hosts deny = 0.0.0.0/32auth users = rsync_backupsecrets file = /etc/rsync.password#####################################[www]comment = www by yupan 14:18 2016-02-23path = /data0/www/www/#####################################[bbs]comment = bbs by yupan 14:18 2016-02-23path = /data0/www/bbs/#####################################[blog]comment = blog by yupan 14:18 2016-02-23path = /data0/www/blog/#####################################[backup]comment = blog by yupan 14:18 2016-02-23path = /backup/#####################################[nfs]comment = blog by yupan 14:18 2016-02-23path = /backup/nfs/

②密码及权限设置

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

chmod 600 /etc/rsync.password

③启动Rsync

启动（daemon模式）

rsync --daemon

加入开机自启动

echo "/usr/bin/rsync --daemon" >> /etc/rc.local

检查开机启动

cat /etc/rc.local

检查Rsync进程(二选一)

ps -ef|grep rsync

netstat -lntup|grep rsync

重启服务

killall rsync

rsync --daemon

④创建共享目录

mkdir -p /data0/www/{bbs,www,blog}

二、客户端配置

①生成密码文件

echo "panda" > /etc/rsync.passwordchmod 600 /etc/rsync.password

②测试同步功能

rsync -avz a.txt rsync_backup@192.168.174.10::www/ --password-file=/etc/rsync.password

③服务端验证

服务端防火墙需rsync通行

 ④Inotify配置

创建tools、scripts文件夹集中管理软件包及脚本文件，编译安装Inotify-3.14

mkdir  -p /home/toolsmkdir -p /home/scriptscd /home/tools/tar xf inotify-tools-3.14.tar.gz cd inotify-tools-3.14./configure --prefix=/usr/local/inotify-tools-3.14make && make installln -s /usr/local/inotify-tools-3.14/ /usr/local/inotify

 

Inotify简易脚本调试，后台运行

vim /home/scripts/inotify.sh

 

#!/bin/shdir="/usr/local/inotify-tools-3.14/bin/inotifywait"$dir -mrq --timefmt '%d/%m/%y %H:%M' --format '%w%f' -e delete,create,close_write /backup|while read linedo   cd /   rsync -az --delete /backup/ rsync_backup@192.168.174.10::nfs --password-file=/etc/rsync.passworddone

 

sh /home/scripts/inotify.sh &

 

⑤测试同步效果

服务端：

客户端：

客户端开始生成文件：

touch {a..z}

查看服务端文件夹：

 

三、Rsync+Inotify优缺点

1，rsync是单向传输。

2，可以互为服务端及客户端

3，同步时不会陷入循环

4，并发较小，不能适用大型集群
