   GNU Parted 3.2
   Using /dev/sdb
   Welcome to GNU Parted! Type 'help' to view a list of commands.

2. 格式化分区 （parted只能针对gpt格式的磁盘进行操作）
   (parted) mklabel gpt
3. 分区
   (parted) mkpart primary 0% 100% or
   (parted) mkpart primary 1 800 # 单位M
4. 退出
   q
5. 格式化
   mkfs.ext4 /dev/sdb1
6. 创建要所挂载的目录
   mkdir /database
7. mount
   mount /dev/sdb1 /database

其他命令
