rsync的helloworld

http://blog.leezhong.com/project/2010/12/13/inotify-rsync.html
这个写得不对
rsync -av --progress --include=kk --exclude='*' --password-file=/etc/rsyncd.secrets /opt/backuptest/ haha@10.1.224.171::test
[color=red]include必须写在exclude前面才起作用，要不就是exclude的*把所有的都覆盖了[/color]

inotify+rsync实时同步

-a 相当于 -rlptgoD 的集合
-u 等同于 --update，在目标文件比源文件新的情况下不更新
-v 显示同步的文件
--progress 显示文件同步时的百分比进度、传输速率
--delete 删除目标目录中多于源目录的文件

[color=red]注意：[/color]
1.启动用rsync --daemon
2.一定要注意结尾的/，意义不同
3.如果启动不了打开vim /etc/init.d/rsync
RSYNC_ENABLE=true

环境ubuntu11.04

vim /etc/rsyncd.conf

uid = root
gid = root
use chroot = no
max connections = 5
pid file = /var/run/rsync.pid
lock file = /var/run/rsync.lock
log file = /var/log/rsync.log

[backup]
path = /opt/backup
ignore errors
read only = no
list = yes
auth users = haha
secrets file = /etc/rsyncd.secrets

vim /etc/rsyncd.secrets
haha:haha

如果用 rsync -avu --progress --delete /opt/backtest/ haha@192.168.1.100::backup
就会删除掉多余的文件
-----------------------

rsync -av --password-file=/etc/rsyncd.secrets /opt/testhao/ test@192.168.106.101::backuptest
在/etc/rsyncd.secrets中只写test的密码即可
比如服务器端是test:test
客户端则是test
