源主机： 192.168.1.111
目的主机： 192.168.1.28(rsync服务端)
实时监控源主机的某个目录，有更新则立即同步到目标主机
1.在目的主机192.168.1.28安装配置Rsync服务端
yum install rsync -y
创建配置文件 /etc/rsyncd.conf
log file = /var/log/rsyncd.log
pidfile = /var/run/rsyncd.pid
lock file = /var/run/rsync.lock
uid = root
gid = root
port=873
use chroot = no
read only = no
list = no
max connections = 200
timeout = 600
secrets file = /etc/rsync.pass
[yunwei]
path = /data/www/
comment = yunwei
auth users = rsync_user
hosts allow = 192.168.1.111
服务端的密码文件保存 用户名:密码
客户端的密码文件只需要保存密码
启动rsync服务
rsync --config=/etc/rsyncd.conf --daemon
2.在源主机192.168.1.111上安装inotify和rsync客户端
下载地址
http://github.com/downloads/rvoicilas/inotify-tools/inotify-tools-3.14.tar.gz
yum install make gcc gcc-c++
cd /usr/local/src
tar zxvf inotify-tools-3.14.tar.gz
cd inotify-tools-3.14
./configure --prefix=/usr/local/inotify
make
make install
yum install rsync -y
配置密码文件
同步脚本如下，后台运行 nohup sh rsync.sh &
#!/bin/bash
src=/data/website/iworker2/
dst=yunwei
excludedir=/data/scripts/exclude.list
rsyncuser=rsync_user
rsyncpass=/etc/rsync.pass
dstIP=‘192.168.1.28‘
for ip in $dstIP
do
rsync -avP --port=873 --delete --exclude-from=$excludedir $src $rsyncuser@$ip::$dst --password-file=$rsyncpass
done
inotifywait -mrq --timefmt ‘%d/%m/%y/%H:%M‘ --format ‘%T %w %f‘ -e modify,delete,create,attrib /data/website/iworker2 | while read file
do
for ip in $dstIP
do
rsync -avP --port=873 --delete --exclude-from=$excludedir $src $rsyncuser@$ip::$dst --password-file=$rsyncpass
done
done
excludedir=/usr/local/inotify/exclude.list 不需要同步的文件,目录，如果有多个，每一行写一个目录，使用相对路径
