一.rsync常见问题及解决办法
在使用rsync中往往会报错误，接下来吾爱编程把常见的错误列举出来，遇到问题可以查看一下对应的错误，然后解决问题：
错误一：
password file must not be other-accessible
continuing without password file
Password:
rsync客户端路径是否写错，权限设置不对，需要再次输入密码，客户端和服务端的密码文件都应该是600的权限才可以
错误二：
@ERROR: Unknown module ‘bak’
rsync error: error starting client-server protocol (code 5) at main.c(1522) [receiver= 3.0.3]
服务端server的配置中的[bak]名字和客户端client的192.168.2.252::bak不符
错误三：
rsync: failed to connect to 192.168.2.252: Connection timed out (110)
rsync error: error in socket IO (code 10) at clientserver.c(124) [receiver=3.0.6]
检查服务端server服务是否正常启动，检查端口防火墙，iptables打开873端口
如果服务端是windows server则在防火墙入站规则中增加873端口
如果服务端是Linux则先检查服务是否启动#ps aux | grep rsync
然后开启873端口#iptables -A INPUT -p tcp --dport 873 -j ACCEPT开启873端口
附：
安装rsync yum install rsync
启动服务/usr/bin/rsync --daemon
启动服务错误failed to create pid file /var/rsyncd.pid: File exists
看看提示服务错误的路径(这个路径不一定就是这个，看自己的报错路径)这里是/var/rsyncd.pid所以
rm -rf /var/rsyncd.pid;再重新启动Rsync服务
此时在看一下ps aux | grep rsync启动成功
错误四：
@ERROR: access denied to gmz88down from unknown (192.168.2.252)
rsync error: error starting client-server protocol (code 5) at main.c(1503) [receiver=3.0.6]
看看是不是服务端server hosts allow限制了IP，把这里的IP加入到服务端server的hosts allow白名单中，windows rsync不能写多个allow，可以在一个allow中加多个IP，例：hosts allow=192.168.2.252 20.20.20.20
错误五：
@ERROR: chdir failed
rsync error: error starting client-server protocol (code 5) at main.c(1503) [receiver=3.0.6]
服务端server的目录不存在或者没有权限(要同步的那个文件路径)，安装windows rsync时候会创建一个SvcCWRSYNC用户，这个用户对要拷贝的目录没有权限，方法一，将这个用户给权限加入到目录中，方法二，修改这个用户隶属于的组，修改后要在管理中重启服务
错误六：
rsync error: error starting clie
nt-server protocol (code 5) at main.c(1524) [Receiver= 3.0.7 ]
/etc/rsyncd.conf配置文件内容有错误，检查下配置文件
错误七：
rsync: ch
own "" failed: Invalid argument (22)
权限无法复制，去掉同步权限的参数即可
错误八：
@ERROR: auth failed on module bak
rsync error: error starting client-server protocol (code 5) at main.c(1530) [receiver=3.0.6]
密码错误或服务器上是否有bak模块
错误九：
rsync: connection unexpectedly closed (5 bytes received so far) [sender]
rsync error: error in rsync protocol data stream (code 12) at io.c(600) [sender=3.0.6]
模块read only = no设置为no false
错误十：
@ERROR: invalid uid nobody
rsync error: error starting client-server protocol (code 5) at main.c(1503) [sender=3.0.6]
设置
uid =0
gid = 0
错误十一：
rsync: failed to connect to 192.168.2.252: No route to host (113)
rsync error: error in socket IO (code 10) at clientserver.c(124) [receiver=3.0.6]
防火墙原因
错误十二：
rsync: read error: Connection reset by peer (104)
rsync error: error in rsync protocol data stream (code 12) at io.c(759) [receiver=3.0.6]
/etc/rsyncd.conf配置文件不存在
错误十三：
rsync: Failed to exec ssh: No such file or directory (2)
rsync error: error in IPC code (code 14) at pipe.c(84) [receiver=3.0.6]
rsync: connection unexpectedly closed (0 bytes received so far) [receiver]
rsync error: error in IPC code (code 14) at io.c(600) [receiver=3.0.6]
需要在客户端安装yum install -y openssh-clients即可
错误十四：
rsync error: some files/attrs were not transferred (see previous errors) (code 23) at main.c(1518) [generator=3.0.9]
服务端没有写权限，修改rsyncd.conf中uid和gid
错误十五：
rsync: failed to connect to 192.168.2.252 (192.168.2.252): Connection refused(111)
rsync error: error in socket IO (code 10) at clientserver.c(128) [sender=3.1.1]
rsync没启动
错误十六：
rsync: safe_read failed to read 1 bytes [Receiver]: Connection reset by4)
rsync error: error in rsync protocol data stream (code 12) at io.c(285)r=3.1.1]
server端防火墙和rsyncd.conf配置文件没有添加当前IP白名单
错误十七：
sending incremental file list
rsync: read error: Connection reset by peer (104)
rsync error: error in socket IO (code 10) at io.c(785) [sender=3.1.2]
服务端设置read only = false
错误十八：
使用rsync密钥传输时报以下错误
Unexpected remote arg: [email protected]:/home/wwwroot/down.itbiancheng.com
rsync error: syntax or usage error (code 1) at main.c(1201) [sender=3.0.6]
解决办法：
错误-azveP
正确-azvPe
这个报错就是顺序的问题，-e后面要跟着'ssh -p 22'
错误十九：
rsync: write failed on "123/01.jpg" (in itbiancheng): No space left on device (28)
rsync error: error in file IO (code 11) at receiver.c(393) [receiver=3.1.2]
rsync error: error in file IO (code 11) at io.c(1633) [generator=3.1.2]
磁盘空间不足，df -h检查磁盘空间
二.开启服务报错 错误1069：由于登录失败而无法启动服务
当开机用户密码更改之后，会导致SQL Server (MSSQLSERVER)服务不能启动，报“错误1069：由于登录失败而无法启动服务”
数据库登录不进去
解决办法：
双击“SQL Server (MSSQLSERVER)服务”，选择“登录”选项卡，更改密码即可
