实现功能:当用户在本地客户端某目录内建立、修改、删除目录或文件、修改目录或文件的属性,只要执行相同的shell脚本,rsync就会自动找出有改动或删除的数据,将其传送到服务器上,使服务器端某目录内的数据跟本地客户端某目录内的数据保持一致。

  ★方式一:

  一、服务器端(例:10.0.0.1*):
  1、创建用户和组

groupadd www -g 48
useradd -u 48 -g www www
mkdir -p /opt/htdocs
chmod +w /opt/htdocs
chown www:www /opt/htdocs


  2、编辑rsync的配置文件
vi /etc/rsyncd.conf

  输入以下内容:
引用
uid=www
gid=www
max connections=10
use chroot=no
log file=/var/log/rsyncd.log
pid file=/var/run/rsyncd.pid
lock file=/var/run/rsyncd.lock

[zhangyan]
path=/opt/htdocs
comment = my htdocs
ignore errors
read only = no
hosts allow=10.0.0.21 10.0.0.22


  3、启动rsync服务器端
/usr/bin/rsync --daemon


  二、客户端(例:10.0.0.21和10.0.0.22):
  1、创建一个shell脚本push.sh
vi push.sh

  输入以下内容(10.0.0.1*为要推送到的目标服务器,zhangyan为服务器端rsyncd.conf配置文件中的模块名):
引用
#!/bin/sh
/usr/bin/rsync -vzrtopg --delete $1 10.0.0.10::zhangyan/
/usr/bin/rsync -vzrtopg --delete $1 10.0.0.11::zhangyan/
/usr/bin/rsync -vzrtopg --delete $1 10.0.0.16::zhangyan/
/usr/bin/rsync -vzrtopg --delete $1 10.0.0.19::zhangyan/
  注:因为是内部局域网之间传输,这里没有设置密码。

  2、赋予push.sh执行权限
chmod +x ./push.sh


  3、同步推送客户端某个目录中(例:/home/zhanguan/abc)的文件到服务器端的/opt/htdocs目录:
./push.sh /home/zhanguan/abc/

  注意:不要忘了abc后面的/。如果更改的文件太大,可以在上面语句的末尾加上空格和&号,推到后台执行。例:
./push.sh /home/zhanguan/abc/ &



  ★方式二:

  一、服务器端(例:10.0.0.1*):
  1、创建用户和组
groupadd www -g 48
useradd -u 48 -g www www
mkdir -p /opt/htdocs
chmod +w /opt/htdocs
chown www:www /opt/htdocs
passwd www
  为www用户设置一个密码。

  二、客户端:
  1、同步推送客户端某个目录中(例:/home/zhanguan/abc)的文件到服务器端的/opt/htdocs目录:
/usr/bin/rsync -vzrtopg --delete /home/zhanguan/abc/ -e ssh www@10.0.0.10:/opt/htdocs/
  输入密码,回车即可,无须服务器端启动rsync服务。

请问 windows2003 下能使用此软件2台机器互相同步数据么?
如何操作呢?

rsync有winodws版本,可以实现在Windows2003下的同步备份。

请问rsync如何限速,如果大文件同步会导致同步期间带宽被占用完,按网上说的用参数--bwlimit来限速,但是测试了下貌似没什么效果。
