Rsync服务常见问题汇总

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

6. 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
      [root@backup backup]# /etc/init.d/xinetd restart
      shell-init: error retrieving current directory: getcwd: cannot access parent directories: No such file or directory
      Stopping xinetd: [ OK ]
      Starting xinetd: shell-init: error retrieving current directory: getcwd: cannot access parent directories: No such file or directory
      [ OK ]
      说明：如果没有备份存储目录，xinetd服务都不能正确启动

7. 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

8. 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

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

9. rsync客户端连接慢问题
