rsync故障案例--解决

rsync故障案例--解决

1.1 rsync客户端执行rsync命令错误：

   客户端的错误现象：  

   [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)

1.2 @ERROR: auth failed on module oldboy

   客户端的错误现象：

   [root@nfs01 tmp]# rsync -avz /etc/hosts rsync_backup@172.16.1.41::backup

   Password:

   @ERROR: auth failed on 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：

   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

   3. /etc/rsync.password文件权限不是600

   4. rsync_backup:123456密码配置文件后面注意不要有空格

      echo "rsync_backup:123456" >>/etc/rsync.password



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

1.3 Unknown module 'backup'

[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：

      1. /etc/rsyncd.conf配置文件模块名称书写错误

1.4 Permission denied

[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. 共享目录的属主和属组不正确，不是rsync

      2. 共享目录的权限不正确，不是755

1.5 chdir failed

[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

1.6 invalid uid rsync

[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

1.7 客户端已经配置了密码文件，但免秘钥登录方式，依旧需要输入密码

   password file must not be other-accessible

[root@nfs01 tmp]# rsync -avz /etc/hosts rsync_backup@172.16.1.41::backup --password-file=/etc/rsync.password

password file must not be other-accessible

continuing without password file

Password:

sending incremental file list



sent 26 bytes  received 8 bytes  5.23 bytes/sec

total size is 349  speedup is 10.26

异常问题解决：

   rsync客户端的秘钥文件也必须是600权限
