客户端A安装rsync+inotify-tools
主服务器
1）安装rsync
1、apt-get install[remove] rsync
2、touch /etc/rsync/rsyncd.conf
uid = root
gid = root
port = 873
hosts allow = 47.92.27.140
use chroot = true
max connections = 200
timeout = 600
pid file = /var/run/rsyncd.pid
lock file = /var/run/rsync.lock
log file = /var/log/rsyncd.log
[default]
path = /home/default
comment = default
ignore errors
read only = no
list = no
auth users = suicy
secrets file = /etc/rsyncd.passwd
3、touch rsyncd.passwd
suicy:suicy
chmod 600 /etc/rsyncd.passwd
4、rsync --daemon; 启动成功
出现以上结果，表明rsync服务器端已经启动。
2）安装inotify
1、wget http://github.com/downloads/rvoicilas/inotify-tools/inotify-tools-3.14.tar.gz
2、tar zxvf inotify-tools-3.14.tar.gz
3、cd inotify-tools-3.14
4、./configure -prefix=/usr/local/inotify
make
make install
3）创建rsync复制脚本
将server端的目录/tmp里的内容,如果修改了（无论是添加、修改、删除文件）能够通过inotify监控到,并通过rsync实时的同步给client的/home/default里,下面是通过shell脚本实现的
rsync -vzrtopg --delete --progress --password-file=/usr/local/rsync/rsync.passwd $src $user@$host::$des 

inotify_back.sh
#!/bin/bash
src=/home/default/
/usr/local/inotify/bin/inotifywait -mrq --timefmt '%d/%m/%y %H:%M' --format '%T %w%f%e' -e close_write,delete,create,attrib $src |  while read file
do
   /usr/bin/rsync -auvrtzopgP --progress --password-file=/etc/rsyncd.pwd /home/default/ [email protected]::default
     echo "${file} was rsynced">>/usr/log/rsync.log 2>&1
done
3）创建rsync密码文件
touch /etc/rsyncd.pwd 
4）启动
rsync --daemon
sh inotify_back.sh &


配置文件错误：error starting client-server protocol (code 5) at main.c(1653) [sender=3.1.1]

启动错误：failed to create pid file /var/run/rsyncd.pid: File exists
解决方案：rm -rf /var/run/rsyncd.pid 再重新启动Rsync服务（rsync --daemon）

同步错误：Unknown module 'default'
解决方案：inotify_back.sh url错误

连接拒绝：failed to connect to 120.77.244.96 (120.77.244.96): Connection refused 
解决方案：对方rsync没有开启

@ERROR: auth failed on module default 
解决方案：验证配置文件密码问题


报错：connection unexpectedly closed (0 bytes received so far) [sender]
