5、client端测试
创建密码文件，只填密码即可，密码要与server端的一致。
debian-vm:~# vi /etc/rsyncd.secrets
123456
同步
debian-vm:~# /usr/bin/rsync -vzrtopg --delete --progress appbackup@192.168.206.120::www /data/webroot --password-
file=/etc/rsyncd.secrets

参数说明：
-vzrtopg里的v是verbose，z是压缩，r是recursive，topg都是保持文件原有属性如属主、时间的参数。
--progress是指显示出详细的进度情况
--delete是指如果服务器端删除了这一文件,那么客户端也相应把文件删除
6、crontab定期更新脚本
# more rsync.sh
#!/bin/bash
#列表显示远程的目录
/usr/bin/rsync -vzrtopg --delete --progress appbackup@192.168.206.120::www --password-file=/etc/rsyncd.secrets
/usr/bin/rsync -vzrtopg --delete --progress appbackup@192.168.206.120::www /data/webroot --password-
file=/etc/rsyncd.secrets
