rsync在使用中往往会报错误，总结几条错误的解决方案（IP以10.10.10.10代替）：
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10.10.10.10::bak不符错误三：
rsync: failed to connect to 10.10.10.10: 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 (10.10.10.10)
 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=10.10.10.10 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 10.10.10.10: 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 10.10.10.10 (10.10.10.10): 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: root@10.10.10.10:/home/wwwroot/blog.whsir.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 whsir): 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
错误二十：
@ERROR: failed to open lock file
 rsync error: error starting client-server protocol (code 5) at main.c(1648) [Receiver=3.1.2]在服务端中添加lock file = rsyncd.lock
