rsync 常见错误以及解决办法
rsync: read error: Connection reset by peer (104)
rsync error: error in rsync protocol data stream (code 12) at io.c(794) [receiver=3.0.2]
解决：很大可能是服务器端没有开启 rsync 服务。开启服务。
错误2：
@ERROR: chdir failed
rsync error: error starting client-server protocol (code 5) at main.c(1495) [receiver=3.0.2]
解决：服务器端同步目录没有权限，cwrsync默认用户是Svcwrsync。为同步目录添加用户Svcwrsync权限。
错误3：
@ERROR: failed to open lock file
rsync error: error starting client-server protocol (code 5) at main.c(1495) [receiver=3.0.2]
解决：配置文件 rsync.conf中添加 lock file = rsyncd.lock 即可解决
错误4：
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]
解决：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
错误5：
@ERROR: auth failed on module backup
rsync error: error starting client-server protocol (code 5) at main.c(1506) [Receiver=3.0.7]
解决：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
错误6：
@ERROR: chdir failed
rsync error: error starting client-server protocol (code 5) at main.c(1506) [Receiver=3.0.7]
解决：服务器端的/data/backup 其中backup这个目录并没有设置，所以提示：chdir failed
错误7：
rsync: write failed on “/data/backup”: No space left on device (28)
rsync error: error in file IO (code 11) at receiver.c(302) [receiver=3.0.7]
解决：磁盘空间不够，所以无法操作。
错误8：
rsync: opendir “/kexue” (in dtsChannel) failed: Permission denied (13)
解决：注意查看同步的目录权限是否为755
错误9：
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]
解决：连接时间超时，检查服务器的端口netstat –tunlp，远程telnet测试。
错误10：
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]
解决：rsync服务未启动，启动rsync服务：rsync –daemon –config=/etc/rsyncd.conf
错误11：
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]
解决：Ctrl+C或者大量文件
错误12：
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]
解决：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.
