【集群实战】Rsync常见错误总结

1. 服务端指定模块没有对应目录

报错详情：

@ERROR: chdir failed

rsync error: error startingclient-server protocol (code 5) at main.c(1503) [sender=3.0.6]

错误原因

服务端指定模块没有对应目录

解决方法

[root@nfs01 ~]# mkdir –p /backup 在服务端创建指定模块对应目录

2. 服务端目录属主和数组不正确

报错详情：

rsync error: some files/attrs were not transferred (see previous errors) (code 23) at main.c(1039) [sender=3.0.6]

错误原因

1> 服务端配置文件中指定的用户和模块指定的目录的属主属组不同

2> 服务端模块指定的目录属组属组没有权限

解决方法

将模块指定目录的属主属组修改为配置文件中指定的 uid gid

[root@nfs01 ~]# chown rsync.rsync /backup 配置文件中指定的用户和组

3. 服务端Rsync对目录操作权限不足

报错详情：

sending incremental file list

rsync: ERROR: cannot statdestination "." (in backup): Permission denied (13)

[root@backup ~]# chmod 755 /backup/

4. 认证错误

2> 服务端密码文件不是600

3> 服务端密码文件不存在(名字写错了/没有创建/配置文件参数写错了)

chmod 600 /etc/rsync.password # 客户端和服务端都改

5. 服务端不存在模块
