  错误详细

  一。rsync服务

  1.not a regular file不是普通文件

  scp默认只能复制普通文件与cp类似

  加上-r即可

  [root backup——]#scp/etc/172.16.1.31:/tmp

  root 172.16.1.31's password:

  /etc:not a regular file

  2.remote command not found

  远程服务器中没有这个命令

  检查远程服务器是否安装了rsync没有yum安装即可

  [root backup——]#rsync-av/etc 172.16.1.31:/tmp

  root 172.16.1.31's password:

  bash:rsync:command not found

  rsync:connection unexpectedly closed(0 bytes received so far)[sender]

  rsync error:remote command not found(code 127)at io.c(226)[sender=3.1.2]

  3.Connection refused

  连接拒绝

  检查是否能ping通对应服务器

  [root backup——]#rsync-avz/etc 176.16.1.31:/tmp

  ssh:connect to host 176.16.1.31 port 22:Connection refused

  rsync:connection unexpectedly closed(0 bytes received so far)[sender]

  rsync error:unexplained error(code 255)at io.c(226)[sender=3.1.2]

  4.auth failed on module data

  data模块认证错误(密码)

  原因:

  1.密码写错

  2.密码文件不存在

  3.密码文件权限不对

  [root backup log]#rsync-avz/etc/hosts rsync_backup 172.16.1.41::data

  Password:

  ERROR:auth failed on module data

  rsync error:error starting client-server protocol(code 5)at main.c(1648)[sender=3.1.2]

  5.secrets file

  日志中

  密码文件问题

  查看日志的提示:

  019/05/20 16:52:32[15755]secrets file must be owned by root when running as root(see strict modes)

  2019/05/20 16:52:32[15755]auth failed on module data from backup(172.16.1.41)for rsync_backup:ignoring secrets file

  secrets file must be owned by root when running as root(see strict modes)

  密码文件当root运行rsync的时候,必须属于root

  [root backup——]#ll/etc/rsync.password

  -rw-------1 rsync rsync 20 May 20 16:49/etc/rsync.password

  6.Unknown module'data'

  未知的模块

  [root backup——]#rsync-avz/etc/hosts rsync_backup 172.16.1.41::data

  ERROR:Unknown module'data'

  rsync error:error starting client-server protocol(code 5)at main.c(1648)[sender=3.1.2]

  7.read error:Connection reset by peer

  配置文件错误

  [root backup——]#rsync-avz/etc/hosts rsync_backup 172.16.1.41::data

  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]

  8.password file must not be other-accessible

  rsync-avz/etc/sysconfig/rsync_backup 172.16.1.91::backup--password-file=/etc/rsync.password

  ERROR:password file must not be other-accessible

  rsync error:syntax or usage error(code 1)at authenticate.c(196)[sender=3.1.2]

  9.Unknown module'data'

  ERROR:Unknown module'data'

  2019/05/20 17:45:46[10514]rsync denied on module data from UNKNOWN(10.0.0.31)

  10.Name or service not known

  [root nfs01——]#rsync-avz/etc/hostname rsync_backup backup::backup

  rsync:getaddrinfo:backup 873:Name or service not known

  rsync error:error in socket IO(code 10)at clientserver.c(125)[sender=3.1.2]

  11.password mismatch

  服务端设置的密码和客户端不同

  检查服务端(rsyncd.conf secrets file指定的文件用户名:密码)

  检查客户端--password-file指定的密码文件

  auth failed on module backup from(172.16.1.7)for rsync_backup:password mismatch

  12. ERROR:chdir failed

  模块对应的目录不存在

  rsync-avz/etc/hostname rsync_backup 172.16.1.41::nfsbackup--password-file=/etc/rsync.password

  ERROR:chdir failed

  rsync error:error starting client-server protocol(code 5)at main.c(1648)[sender=3.1.2]

  二。NFS

  wrong fs type

  错误的文件系统类型nfs文件系统无法识别

  没有安装nfs-utils

  mount-t nfs 172.16.1.31:/data/mnt/

  mount:wrong fs type,bad option,bad superblock on 172.16.1.31:/data,

  missing codepage or helper program,or other error

  (for several filesystems(e.g.nfs,cifs)you might

  need a/sbin/mount.<type>helper program)

  In some cases useful info is found in syslog-try

  dmesg|tail or so

  No route to host

  没有路由,道路不通。

  ping ip

  防火墙开启

  [root nfs01——]#rpcinfo-p 172.16.0.31

  rpcinfo:can't contact portmapper:RPC:Remote system error-No route to host

  access denied by server while mounting 10.0.0.31:/data

  访问拒绝

  网段

  配置错误

  [root nfs01——]#showmount-e 172.16.1.31

  Export list for 172.16.1.31:

  /data 172.16.1.0/24

  [root nfs01——]#cat/etc/exports

  #share/data to web/upload

  /data 172.16.1.0/24(rw)

  [root nfs01——]#mount-t nfs 10.0.0.31:/data/mnt

  mount.nfs:access denied by server while mounting 10.0.0.31:/data

  Job for nfs-server.service invalid.

  nfs服务未启动所以无法reload

  [root nfs01——]#systemctl stop nfs

  [root nfs01——]#systemctl reload nfs

  Job for nfs-server.service invalid.
