“mount error(13): Permission denied”

环境：CentOS7
挂载报错：

[root@chenshuyi ~]# mount -t cifs //127.0.0.1/printers /tmp/samba
Password for root@//127.0.0.1/printers:
mount error(13): Permission denied
Refer to the mount.cifs(8) manual page (e.g. man mount.cifs)

据说使格式错

[root@chenshuyi ~]# mount -t cifs //127.0.0.1/printers /tmp/samba -o username=smb1,password=123
mount error(5): Input/output error
Refer to the mount.cifs(8) manual page (e.g. man mount.cifs)

“mount error(5): Input/output error”

• 无共享文件（更改smb.conf文件）

• 重启服务，查看文件共享

[root@chenshuyi samba]# smbclient -L //127.0.0.1

• 重新挂载

[root@chenshuyi samba]# mount -t cifs //127.0.0.1/public /tmp/samba -o username=smb1,password=123
mount error(20): Not a directory
Refer to the mount.cifs(8) manual page (e.g. man mount.cifs)

又报错"mount error(20): Not a directory"

• 重新打开samba的主配置文件，共享文件这一块，其他的都注释掉，就剩眼见的。

• 重启服务，重新挂载

[root@chenshuyi home]# mount -t cifs //127.0.0.1/temp /tmp/samba -o username=smb1,password=123
[root@chenshuyi home]# df -h
