报错合集(长期更新)
rsync篇
错误整合一:
image.png
chgrp ".hosts.rFMg5m" (in backup) failed: Operation not permitted (1)
错误为什么产生?
chgrp(修改数据属组信息) fake super = yes (伪装超级用户管理员)此配置未配置好 所以在最后一步将 数据保存在备份目录时修改备份目录为属主属组信息被阻止 更改配置后错误消失
错误整合二:
[root@nfs01 /]# rsync -avz /oldboy/ --exclude=oldboy01/ --exclude=oldboy03/b.txt rsync_backup@172.16.1.41::sa_backup --password-file=/etc/rsync.password
@ERROR: auth failed on module sa_backup
rsync error: error starting client-server protocol (code 5) at main.c(1648) [sender=3.1.2]
因为密码文件设置失误 修改后正常(服务端/dev/rsync.password 需要写 rsync_password:密码信息参见配置文件 客户端只要写密码就可以)1.密码真的输入错误,用户名真的错误2. secrets file = /etc/rsync.password指定的密码文件和实际密码文件名称不一致 信息复制粘贴3. /etc/rsync.password文件权限不是600 服务端4. rsync_backup:123456 密码配置文件后面注意不要有空格
如何看出文件结尾空格信息:
方法一:在vim编辑中查看
底行模式---:set list
方法二:在cat命令中查看
[root@backup ~]# cat -A /etc/rsync.password
rsync_backup:oldboy123 $
5.rsync客户端密码文件中只输入密码信息即可,不要输入虚拟认证用户名称
错误整合三:
image.png
密码文件权限错误,普通用户需要传文件可以在自己的家目录中创建/home/rsync.password密码文件,文件权限必须改为600
四: 如何真正保持文件属主和属组信息不变?
1.uid gid = root
2.注释掉fake sepr = yes
3.确认备份服务端有相应用户信息(uid gid 保持一致)
五: 如何对外网用户限速
--bwlimit=KBPS
rsync -avzP --bwlimit=10 /opt/1G rsync_backup@172.16.1.41::backup --password-file=/etc/rsync.password
sending incremental file list
1G
1,048,576,000 100% 10.67MB/s 0:01:33 (xfr#1, to-chk=0/1)
sent 1,019,827 bytes received 43 bytes 10,147.96 bytes/sec(限速速率 10KB/s)
total size is 1,048,576,000 speedup is 1,028.15
六: 如何修改rsync默认湍口后,依旧可以传输数据信息
方法一: rsync [OPTION...] SRC... rsync://[USER@]HOST[:PORT]/DEST
rsync -avz /etc/hosts rsync_bacakup@172.16.1.41:874/as_backup --password-file=/etc/rsync.password
方法二: rsync -avz /etc/hosts rsync_backup@172.16.41::backup --password-file=/etc/rsync.bassword --port=874
七: rsync服务端开启的iptables防火墙
【客户端的错误】
No route to host
【错误演示过程】
[root@nfs01 tmp]# rsync -avz /etc/hosts rsync_backup@172.16.1.41::backup
rsync: failed to connect to 172.16.1.41: No route to host (113)
rsync error: error in socket IO (code 10) at clientserver.c(124) [sender=3.0.6]
【异常问题解决】
关闭rsync服务端的防火墙服务(iptables)
[root@backup mnt]# /etc/init.d/iptables stop
iptables: Setting chains to policy ACCEPT: filter [ OK ]
iptables: Flushing firewall rules: [ OK ]
iptables: Unloading modules: [ OK ]
[root@backup mnt]# /etc/init.d/iptables status
iptables: Firewall is not running.
八: rsync客户端执行rsync命令错误
【客户端的错误】
The remote path must start with a module name not a /
【错误演示过程】
[root@nfs01 tmp]# rsync -avz /etc/hosts rsync_backup@172.16.1.41::/backup
ERROR: The remote path must start with a module name not a /
rsync error: error starting client-server protocol (code 5) at main.c(1503) [sender=3.0.6]
【异常问题解决】
rsync命令语法理解错误,::/backup是错误的语法,应该为::backup(rsync模块)
九: rsync服务位置模块错误
【客户端的错误】
Unknown module 'backup'
【错误演示过程】
[root@nfs01 tmp]# rsync -avz /etc/hosts rsync_backup@172.16.1.41::backup
@ERROR: Unknown module 'backup'
rsync error: error starting client-server protocol (code 5) at main.c(1503) [sender=3.0.6]
【异常问题解决】
/etc/rsyncd.conf配置文件模块名称书写错误
十: rsync服务权限阻止问题
【客户端的错误】
Permission denied
【错误演示过程】
[root@nfs01 tmp]# rsync -avz /etc/hosts rsync_backup@172.16.1.41::backup
Password:
sending incremental file list
hosts
rsync: mkstemp ".hosts.5z3AOA" (in backup) failed: Permission denied (13)
sent 196 bytes received 27 bytes 63.71 bytes/sec
total size is 349 speedup is 1.57
rsync error: some files/attrs were not transferred (see previous errors) (code 23) at main.c(1039) [sender=3.0.6]
【异常问题解决】
1.备份目录的属主和属组不正确,不是rsync
2.备份目录的权限不正确,不是777
十一: rsync服务备份目录异常
【客户端的错误】
chdir failed
【错误演示过程】
[root@nfs01 tmp]# rsync -avz /etc/hosts rsync_backup@172.16.1.41::backup
Password:
@ERROR: chdir failed
rsync error: error starting client-server protocol (code 5) at main.c(1503) [sender=3.0.6]
【异常问题解决】
1.备份存储目录没有建立
2.建立的备份存储目录和配置文件定义不一致
说明:如果没有备份存储目录
十二: rsync服务无效用户信息
【客户端的错误】
invalid uid rsync
【错误演示过程】
[root@nfs01 tmp]# rsync -avz /etc/hosts rsync_backup@172.16.1.41::backup
Password:
@ERROR: invalid uid rsync
rsync error: error starting client-server protocol (code 5) at main.c(1503) [sender=3.0.6]
【异常问题解决】
rsync服务对应rsync虚拟用户不存在了
十三: rsync客户端连接慢问题
【错误日志信息】 名称或者域名 --- IP dns解析
- 错误日志输出 IP --- 名称或者域名 反向dns解析

【异常问题解决】
查看日志进行分析,编写rsync服务端hosts解析文件
客户端 10.0.0.31 ---> 服务端 识别源地址 10.0.0.31 - RDNS(反向dns解析)
十四: rsync服务没有正确启动
【错误日志信息】
Connection refused (111)
【错误演示过程】
[root@oldboy-muban ~]# rsync -avz /etc/hosts rsync_backup@172.16.1.41::backup
rsync: failed to connect to 172.16.1.41: Connection refused (111)

rsync error: error in socket IO (code 10) at clientserver.c(125) [sender=3.1.2]
因为没有172.16.1.41端口问题 重新配置填写即可
