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.
