加密初始化

# 加密某个硬盘的某个分区
cryptsetup luksFormat /dev/sdc1
# 要键入YES，并设置密码

# 解密这个分区，并进行硬着
cryptsetup open /dev/sdc1 fgn-disk-mapper
# 要输入密码
ll /dev/mapper/
lrwxrwxrwx. 1 root root       7 Nov 23 18:29 fgn-disk-mapper -> ../dm-2

# 格式化这个解密分区，然后挂载
mkfs.ext4 /dev/mapper/fgn-disk-mapper
mount /dev/mapper/fgn-disk-mapper /mnt/fgn-disk/

# 解除挂载并解除映射
umount /mnt/fgn-disk/
cryptsetup close fgn-disk-mapper

挂载

cryptsetup open /dev/sdc1 fgn-disk-mapper
# 要输入密码
mount /dev/mapper/fgn-disk-mapper /mnt/fgn-disk/

解挂

umount /mnt/fgn-disk/
cryptsetup close fgn-disk-mapper
