How CentOS mounts a hard drive

CentOS mount hard disk

1. View currently unmounted hard disks

   # fdisk -l

   

2. Create hard disk partitions

   # fdisk /dev/sdb

   

   
   根据提示，依次输入"n"，"p" "1"，两次回车，"wq"，分区就开始了，很快就会完成。
   

3. format the hard drive

   # mkfs.ext4 /dev/sdb

   

4. Create a mount directory

   # mkdir /data

5. mount hard disk

    

   # mount /dev/sdb /data

6. Set up auto mount at startup

   # vi /etc/fstab

    

   在vi中输入i进入INERT模式，将光标移至文件结尾处并回车，将下面的内容复制/粘贴，然后按Esc键，输入":wq"(不含双引号)保存并退出
   
   /dev/sdb    /data    ext4    defaults    0 0
   

7. restart the server

   # shutdown -r now
