我一直在使用rsync整个下午。 我已经设置了一个rsync服务器，但我不知道如何使用它。
我有两台机器：66和12. 66是服务器，我想把66的数据返回到12，所以我使用rsync。
我做了以下几件事：
在66：
sudo apt-get install xinetd sudo vim /etc/xinetd.d/rsync service rsync { disable = no socket_type = stream wait = no user = root server = /usr/bin/rsync server_args = --daemon log_on_failure += USERID } sudo nano /etc/rsyncd.conf max connections = 2 log file = /var/log/rsync.log timeout = 300 [wwwroot] comment = Public Share path = /home/wwwroot read only = no list = yes uid = nobody gid = nogroup auth userusers = user secrets file = /home/rsync.secrets sudo /etc/init.d/xinetd restart 在12：
rsync -v [email protected]::wwwroot /home/young001/backup --password-file=/home/rsync.pass
它告诉：
skipping directory . sent 4 bytes received 6 bytes 2.86 bytes/sec total size is 0 speedup is 0.00
日志是：
2013/06/12 03:18:18 [30477] name lookup failed for 125.221.225.12: Name or service not known 2013/06/12 03:18:18 [30477] connect from UNKNOWN (125.221.225.12) 2013/06/12 10:18:18 [30477] rsync on ctp/ from young001@UNKNOWN (125.221.225.12) 2013/06/12 10:18:18 [30477] building file list 2013/06/12 10:18:18 [30477] skipping directory . 2013/06/12 10:18:18 [30477] sent 98 bytes received 54 bytes total size 0 2013/06/12 03:19:59 [30484] name lookup failed for 125.221.225.12: Name or service not known 2013/06/12 03:19:59 [30484] connect from UNKNOWN (125.221.225.12) 2013/06/12 10:19:59 [30484] rsync on ctp/ from young001@UNKNOWN (125.221.225.12) 2013/06/12 10:19:59 [30484] building file list 2013/06/12 10:19:59 [30484] skipping directory . 2013/06/12 10:19:59 [30484] sent 98 bytes received 54 bytes total size 0
它似乎告诉该目录是空的，但我不知道哪个目录是空的。
/ home / young001 / backup是一个空目录，/ home / wwwroot不是一个空目录。
我想同步wwwroot备份，所以我做错了什么地方？
使用“a”或其他rsync选项来实际执行除检查以外的其他操作：
rsync -av [email protected].......
顺便说一句，你可以简单地使用rsync和ssh作业，而无需安装rsync服务器。
