CentOS服务器网络数据实时同步之inotify+rsync

实例：

假设web01与web02是公司的网站，我们在内容发布服务器中添加数据，inotify检测到有数据更新通过rsync实时传输到web01与web02。

一、web配置(web01与web02配置几乎一致，留意红色部分)

# vi /etc/rsyncd.conf

# filename:/etc/rsyncd.conf

uid = nobody
gid = nobody

use chroot = no
max cOnnections= 10
# set password
strict modes = yes

pid file = /var/run/rsyncd.pid
lock file = /var/run/rsyncd.lock
log file = /var/log/rsyncd.log

[web_01]
path = /var/www/html
comment = web dir
ignore errors
read Only= no
write Only= no
hosts allow = 172.16.10.0/255.255.255.0
hosts deny = *
list = false
auth = backup
secrets file = /etc/rsyncd.auth

# echo backup:backup>/etc/rsyncd.auth

# chmod 600 /etc/rsyncd.auth

二、内容发布服务器配置

//安装inotify-tool
# tar zxvf inotify-tools-3.14.tar.gz 
# cd inotify-tools-3.14
# ./configure;make;make install

//建立rsync验证文件
# echo backup:backup>/etc/rsyncd.auth
# chmod 600 /etc/rsyncd.auth

[root@10.1 ~]# vi inotify_rsync.sh
#!/bin/bash
# This rsync script based on inotify.

export PATH=/bin:/usr/bin:/usr/local/bin
src=/var/www/html/
dst=/var/www/html/
client1=172.16.10.101
client2=172.16.10.102

user=backup
#password file must not be other-accessible.
Passfiles=/etc/rsyncd.auth

#Wait for change
inotifywait -mrq --timefmt &＃39;%d-%m-%y %H:%M&＃39; --format &＃39;%T %w %fi %e&＃39; --event modify,delete,create,attrib $src|while read files 
	do
	rsync -vzrtopg --progress --delete --password-file=$Passfiles $src $user@$client1::$dst
	rsync -vzrtopg --progress --delete --password-file=$Passfiles $src $user@$client2::$dst
        echo "${files} was rsynced" >> /var/log/inotify_web 2>&1
	done

后台运行以上shell脚本，并在内容发布服务器上进行文件修改等操作
