我们都是通过错误日志查看
在rsyncd.log里面或.err文件里面,大家可以用记事本打开查看。
注意windows下面我们需要给SvcwRsync用户,管理同步目录的所有权限,基本上这样就可以了
问题一:
@ERROR: chroot failed
rsync error: error starting client-server protocol (code 5) at main.c(1522) [receiver=3.0.3]
原因:
服务器端的目录不存在或无权限,创建目录并修正权限可解决问题。
问题二:
@ERROR: auth failed on module tee
rsync error: error starting client-server protocol (code 5) at main.c(1522) [receiver=3.0.3]
原因:
服务器端该模块(tee)需要验证用户名密码,但客户端没有提供正确的用户名密码,认证失败。
提供正确的用户名密码解决此问题。
问题三:
@ERROR: Unknown module ‘tee_nonexists'
rsync error: error starting client-server protocol (code 5) at main.c(1522) [receiver=3.0.3]
原因:
服务器不存在指定模块。提供正确的模块名或在服务器端修改成你要的模块以解决问题。
问题1:
在client上遇到问题:
rsync -auzv --progress --password-file=/etc/rsync.pas [email protected]::backup /home/
rsync: could not open password file "/etc/rsync.pas": No such file or directory (2)
Password:
@ERROR: auth failed on module backup
rsync error: error starting client-server protocol (code 5) at main.c(1506) [Receiver=3.0.7]
遇到这个问题:client端没有设置/etc/rsync.pas这个文件,而在使用rsync命令的时候,加了这个参数--
password-file=/etc/rsync.pas
问题2:
rsync -auzv --progress --password-file=/etc/rsync.pas [email protected]::backup /home/
@ERROR: auth failed on module backup
rsync error: error starting client-server protocol (code 5) at main.c(1506) [Receiver=3.0.7]
遇到这个问题:client端已经设置/etc/rsync.pas这个文件,里面也设置了密码111111,和服务器一致,但是
服务器段设置有错误,服务器端应该设置/etc/rsync.pas ,里面内容root:111111 ,这里登陆名不可缺少
问题3:
rsync -auzv --progress --password-file=/etc/rsync.pas [email protected]::backup /home/
@ERROR: chdir failed
rsync error: error starting client-server protocol (code 5) at main.c(1506) [Receiver=3.0.7]
遇到这个问题,是因为服务器端的/home/backup 其中backup这个目录并没有设置,所以提示:chdir failed
问题4:
rsync: write failed on "/home/backup2010/wensong": No space left on device (28)
rsync error: error in file IO (code 11) at receiver.c(302) [receiver=3.0.7]
rsync: connection unexpectedly closed (2721 bytes received so far) [generator]
rsync error: error in rsync protocol data stream (code 12) at io.c(601) [generator=3.0.7]
磁盘空间不够,所以无法操作。
可以通过df /home/backup2010 来查看可用空间和已用空间
问题5:网络收集问题
1、权限问题
类似如下的提示:rsync: opendir "/kexue" (in dtsChannel) failed: Permission denied (13)注意查看同步的目录权限是否为755
2、time out
rsync: failed to connect to 203.100.192.66: Connection timed out (110)
rsync error: error in socket IO (code 10) at clientserver.c(124) [receiver=3.0.5]
检查服务器的端口netstat �Ctunlp,远程telnet测试。
可能因为客户端或者服务端的防火墙开启 导致无法通信,可以设置规则放行 rsync(873端口) 或者直接关闭防火墙。
还有一种在同步过程中可能会提示没有权限 (将同步目录加上SvcwRsync全部权限即可,更简单的方法就是将SvcwRsync设为管理员即可)
3、服务未启动
rsync: failed to connect to 10.10.10.170: Connection refused (111)
rsync error: error in socket IO (code 10) at clientserver.c(124) [receiver=3.0.5]
启动服务:rsync --daemon --config=/etc/rsyncd.conf
4、磁盘空间满
rsync: recv_generator: mkdir "/teacherclubBackup/rsync……" failed: No space left on device (28)
*** Skipping any contents from this failed directory ***
5、Ctrl+C或者大量文件
rsync error: received SIGINT, SIGTERM, or SIGHUP (code 20) at rsync.c(544) [receiver=3.0.5]
rsync error: received SIGINT, SIGTERM, or SIGHUP (code 20) at rsync.c(544) [generator=3.0.5]
6、xnetid启动
rsync: read error: Connection reset by peer (104)
rsync error: error in rsync protocol data stream (code 12) at io.c(759) [receiver=3.0.5]
查看rsync日志
rsync: unable to open configuration file "/etc/rsyncd.conf": No such file or directory
xnetid查找的配置文件位置默认是/etc下,根据具体情况创建软链接。例如:
ln -s /etc/rsyncd/rsyncd.conf /etc/rsyncd.conf
或者更改指定默认的配置文件路径,在/etc/xinetd.d/rsync配置文件中。
安装完 cwRsync客户端后,开始写bat 执行文件,遇到的第一件事情就是就同步到本地时 目录不认识,报错如下:
The source and destination cannot both be remote.
rsync error: syntax or usage error (code 1) at main.c(1138) [Receiver=3.0.7]
主要原因是cwRsync 不能直接认识本地盘,必须加上 /cygdrive/g/test
意思为g:\test目录
客户端密码文件报错如下:
rsync password file must be owned by root when running as root
万能的GOOGLE告诉我,可以用一个变通的方式解决就是
@echo off
"C:\Program Files (x86)\cwRsync\bin\rsync" -rlptDzv --progress --delete "[email protected]::test" /cygdrive/g/test --password-file=/cygdrive/g/rsync/passws.ps<g:\rsync\passwd.txt
在g:\rsync 下建立了一个文件,写入密码,然后同步密码最后在这个文件中输入即可。如上所例。
rsync问题小结
在用rsync同步数据的时候,经常会出现一些问题,我将遇到的总结如下:
1、权限问题
类似如下的提示:rsync: opendir "/kexue" (in dtsChannel) failed: Permission denied (13)注意查看同步的目录权限是否为755
2、time out
rsync: failed to connect to 203.100.192.66: Connection timed out (110)
rsync error: error in socket IO (code 10) at clientserver.c(124) [receiver=3.0.5]
检查服务器的端口netstat �Ctunlp,远程telnet测试。
3、服务未启动
rsync: failed to connect to 10.10.10.170: Connection refused (111)
rsync error: error in socket IO (code 10) at clientserver.c(124) [receiver=3.0.5]
启动服务:rsync --daemon --config=/etc/rsyncd.conf
4、磁盘空间满
rsync: recv_generator: mkdir "/teacherclubBackup/rsync……" failed: No space left on device (28)
*** Skipping any contents from this failed directory ***
5、Ctrl+C或者大量文件
rsync error: received SIGINT, SIGTERM, or SIGHUP (code 20) at rsync.c(544) [receiver=3.0.5]
rsync error: received SIGINT, SIGTERM, or SIGHUP (code 20) at rsync.c(544) [generator=3.0.5]
6、xnetid启动
rsync: read error: Connection reset by peer (104)
rsync error: error in rsync protocol data stream (code 12) at io.c(759) [receiver=3.0.5]
查看rsync日志
rsync: unable to open configuration file "/etc/rsyncd.conf": No such file or directory
xnetid查找的配置文件位置默认是/etc下,根据具体情况创建软链接。例如:
ln -s /etc/rsyncd/rsyncd.conf /etc/rsyncd.conf
常见错误:
错误一
rsync: failed to connect to 96.44.169.178 (*inet_ntop failed*): Connection timed
out (116)
1 [main] rsync 3468 exception::handle: Exception: STATUS_ACCESS_VIOLATION
740 [main] rsync 3468 open_stackdumpfile: Dumping stack trace to rsync.exe.s
tackdump
1,防火墙问题
2,端口不对
错误二
@ERROR: auth failed on module www
rsync error: error starting client-server protocol (code 5) at main.c(1516) [Rec
eiver=3.0.8]
密码不对
错误三
@ERROR: invalid uid nobody
rsync error: error starting client-server protocol (code 5) at main.c(1516) [Rec
eiver=3.0.8]
UID不对,默认是nobody
解决方法:
uid = 0
gid = 0
错误四
receiving incremental file list
rsync: read error: Connection reset by peer (104)
rsync error: error in rsync protocol data stream (code 12) at io.c(769) [receive
r=3.0.8]
rsync: connection unexpectedly closed (60 bytes received so far) [generator]
rsync error: error in rsync protocol data stream (code 12) at io.c(610) [generat
or=3.0.8]
可能原因:
1,磁盘挂载是用异步的(async)
然后,检查了/etc/fstab ,去掉async参数。
2,我在服务器上查看日志,看到有这么一行:
rsync: unable to open configuration file "/etc/rsyncd.conf": No such file or directory
于是我:
ln -s /etc/rsyncd/rsyncd.conf /etc/rsyncd.conf
3,同步文件数较多的目录出错
有个子目录中文件较多,也就8000来个吧,总是同步一半便退出。在批处理中加上-v参数,看到错误信息如下:
rsync: writefd_unbuffered failed to write 4 bytes to socket [sender]: Connection reset by peer (104)
rsync: read error: Connection reset by peer (104)
rsync error: error in rsync protocol data stream (code 12) at io.c(768) [sender=
3.0.6]
这个问题有点头疼,在www.itefix.no网站论坛上也没能查出个所以然。
不过最终还是在samba.org上找到解决方案:
在客户端命令行中加上--no-iconv参数就可以了。
原以为是文件太多,缓冲区不够引起,但看这个解决方案,似乎是转换编码方面的bug了。
在rsync的文档中描述如下:
http://rsync.samba.org/ftp/rsync/rsync.html
--iconv=CONVERT_SPEC
Rsync can convert filenames between character sets using this option. Using a CONVERT_SPEC of "." tells rsync to look up the default character-set via the locale setting. Alternately, you can fully specify what conversion to do by giving a local and a remote charset separated by a comma in the order --iconv=LOCAL,REMOTE, e.g. --iconv=utf8,iso88591. This order ensures that the option will stay the same whether you're pushing or pulling files. Finally, you can specify either --no-iconv or a CONVERT_SPEC of "-" to turn off any conversion. The default setting of this option is site-specific, and can also be affected via the RSYNC_ICONV environment variable.
在window上,rsync同步数据报错:
rsync error: some files/attrs were not transferred (see previous errors) (code 2 3) at main.c(1052) [sender=3.0.8]
原因:
因为rsync服务端执行的用户对同步的文件没有写入权限。
默认rsync是以SvcCWRSYNC此用户运行的,而一般同步的文件此用户是没有写入权限的。SvcCWRSYNC默认归属于User组。
将rsync的服务器端SvcCWRSYNC此用户隶属于加到administrator组就可以解决上面的报错。
