急需使用rsync在家里的多台机器上同步相片。
sudo apt-get install rsync
sudo update-rc.d -f rsync remove
sudo update-rc.d rsync start 20 2 3 4 5 . stop 20 0 1 6 .
sudo update-rc.d rsync enable
hua@node1:~$ sudo sysv-rc-conf --list rsync
rsync 0:off 1:off 2:on 3:on 4:on 5:on 6:off
这时候就可以在一台机器上同步目录了:
rsync -avzur --progress --delete /bak/tmp/qnap/ /qnap/
在多台机器上同步目录：
rsync -rave "ssh -p 22 -l hua" -avzur --progress --delete 192.168.99.124:/qnap/ /qnap/
等价于：rsync -avzur --progress --delete hua@192.168.99.124:/qnap/ /qnap/
也可以配置使用::qnap使用下列配置文件/etc/rsyncd.conf中的[qnap]模块：
sudo rsync -avrzP hua@192.168.99.124::qnap qnap
hua@node1:~$ sudo rsync --list-only hua@192.168.99.124::
++++++++++++++++++++++++++++++++++++++++++++++
Welcome to use quqi rsync services!
++++++++++++++++++++++++++++++++++++++++++++++
qnap This is qnap backup data
配置[qnap]模块的步骤如下：
sudo touch /etc/rsyncd.conf
sudo touch /etc/rsyncd.motd
hua@node1:~$ sudo cat /etc/rsyncd.motd

Welcome to use quqi rsync services!

sudo touch /etc/rsyncd.secrets
hua@node1:~$ sudo cat /etc/rsyncd.secrets
hua:Passw0rd
sudo chmod 600 /etc/rsyncd.secrets
sudo chown root:root /etc/rsyncd.secrets
hua@node1:~$ sudo cat /etc/default/rsync |grep 'RSYNC_ENABLE'
RSYNC_ENABLE=true
sudo /etc/init.d/rsync restart
sudo iptables -A INPUT -p tcp -m state --state NEW -m tcp --dport 873 -j ACCEPT

#usermod -g root hua

[qnap]
path = /qnap
list=yes # 可以使用rsync --list-only hua@192.168.99.124::命令列出目录
ignore errors
auth users = hua,root
secrets file = /etc/rsyncd.secrets
comment = This is qnap backup data
exclude = tmp/ test/
例如，下列的/qnap目录是我通过iscsi挂载的qnap nas的一个目录，一次性通过一个命令（rsync -avzur --progress --delete /bak/Qsync/ /qnap/）将要在各个电脑上同步的数据拷到qnap之后，今后对数据的修改统一在/qnap目录修改，然后其他机器通过下列命令同步最新的数据：
rsync -avrzP hua@192.168.99.124::qnap /bak/Qsync/
rsync -avrzP --exclude 'doc' --exclude 'photo' --exclude 'media' hua@192.168.99.124::qnap /bak/Qsync/
