三、添加硬盘后增加新的共享文件夹

  1. 查看服务器安装的硬盘状态(==可以看到有sdb硬盘，但是没有分区==)

    Sector size (logical/physical): 512 bytes / 512 bytes
    I/O size (minimum/optimal): 512 bytes / 512 bytes

    Changes will remain in memory only, until you decide to write them.
    Be careful before using the write command.

4.格式化分区(mkfs -t ext4 -c /dev/sdb1)

-t 制定要把磁盘格式化成什么类型

-c 在建立文件系统之前检查坏道

5.挂载目录

mkdir /document
mount /dev/sdb1 /document

[root@localhost /]# df -h

/dev/sdb1        20G   45M   19G   1% /document

6.设置开机自动挂载(先用blkid命令查看分区的UUID，使用UUID来绑定挂载的目录)

7.重启系统后df -h查看是否自动挂载

1
2
[root@localhost ~]# df -h |grep /dev/sdb1
/dev/sdb1        20G   45M   19G   1% /document

8.将挂载的目录设置为新的共享文件夹

修改配置文件/etc/samba/smb.conf

9.重启smb服务,配置完成

service smb restart
