Centos6安装配置rsync+inotify实时单向同步

2台y

实验环境：
Server ： 192.168.9.109  rsync+inotify
WEB1：192.168.9.106   rsync server
WEB2：192.168.9.104   rsync server
Server为分发机，有内容更新则推送rsync server
注：也可以WEB到Server拉取数据

（1）Server下载安装rsync+inotify
下载安装rsync
#wget https://download.samba.org/pub/rsync/rsync-3.1.2.tar.gz
#tar xf rsync-3.1.2.tar.gz
#cd rsync-3.1.2
#./configure
#make
#make install
下载安装inotify
# uname -r
2.6.32-431.el6.x86_64  
# ls -l /proc/sys/fs/inotify
total 0
-rw-r--r-- 1 root root 0 Aug 30 12:28 max_queued_events
-rw-r--r-- 1 root root 0 Aug 30 12:28 max_user_instances
-rw-r--r-- 1 root root 0 Aug 30 12:28 max_user_watches
如果有上面三项输出，表示系统已经默认支持inotify，接着就可以开始安装inotify-tools了。
# cd /usr/local/src/
# wget http://github.com/downloads/rvoi ... y-tools-3.14.tar.gz
# tar xf inotify-tools-3.14.tar.gz
# cd inotify-tools-3.14
# ./configure
# make
# make install
# ll /usr/local/bin/inotifywa*
-rwxr-xr-x 1 root root 44287 Aug 31 12:23 /usr/local/bin/inotifywait
-rwxr-xr-x 1 root root 41377 Aug 31 12:23 /usr/local/bin/inotifywatch
#inotify-tools安装完成后，会生成inotifywait和inotifywatch两个指令，其中，inotifywait用于等待文件或文件集上的一个特定事件，它可以监控任何文件和目录设置，并且可以递归地监控整个目录树。  inotifywatch用于收集被监控的文件系统统计数据，包括每个inotify事件发生多少次等信息。

配置SERVER节点：
# vim /data0/inotify.sh
#!/bin/bash
host1=192.168.9.104
host2=192.168.9.106

src=/webroot/
dst1=WEB1
dst2=WEB2
/usr/local/bin/inotifywait -mrq --timefmt '%d/%m/%y %H:%M' --format '%T %w%f%e' \
-e modify,delete,create,attrib ${src} | which read file
do
    /usr/bin/rsync -vzrtopg --delete --progress ${src} ${host1}::${dst1}
    /usr/bin/rsync -vzrtopg --delete --progress ${src} ${host2}::${dst2}
    echo "${files} was rsyncd" > /tmp/rsync.log 2>&1
done
# chmod +x /data0/inotify.sh
# nohup /data0/inotify.sh &
# echo  "nohup /data0/inotify.sh &" >> /etc/rc.d/rc.local

（2）WEB1安装rysnc
下载安装rsync
#wget https://download.samba.org/pub/rsync/rsync-3.1.2.tar.gz
#tar xf rsync-3.1.2.tar.gz
#cd rsync-3.1.2
#./configure
#make
#make install
配置rsync
# cat /etc/rsyncd.conf

启动
#/usr/local/bin/rsync --daemon --config=/etc/rsyncd.conf
#echo "/usr/local/bin/rsync --daemon --config=/etc/rsyncd.conf" >> /etc/rc.d/rc.local

（3）WEB2下载安装rsync
#wget https://download.samba.org/pub/rsync/rsync-3.1.2.tar.gz
#tar xf rsync-3.1.2.tar.gz
#cd rsync-3.1.2
#./configure
#make
#make install
