  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.
