错误详细
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.
