Linux Partitioning and disk encryption

Why Disk Encryption? That's because everyone has their own privacy! When you put your privacy on a disk and don't want to be seen by others, you can encrypt the disk. Down I'll show you the specific encryption steps.

First: A section in the system that you want to put your privacy in

 650 "this.width=650;" src= "/HTTP/ s8.sinaimg.cn/mw690/0062amvsty6usbv9x71e7&690 "width=" 690 "height=" 329 "name=" image_operate_92221438953591046 "alt=" Redhat partition and Disk Encryption "title=" Redhat partition and Disk Encryption "style=" Margin:0px;padding:0px;border:0px;list-style:none; "/>

second: to divide the area after the good area format

/dev/vdb1 format xfs format. Of course, it can also be formatted as ext4/2 format Span style= "font-family: ' Times New Roman ';" >)

third:

fourth: )

fifth:

sixth:

Seventh Touch file/mnt(using encryption device)

Eighth:umount/mnt (uninstall encryption device)

Nineth: /dev/mapper/ xxb )

automatic mount encryption device on boot

For example, the password is redhat1357

 650 "this.width=650;" src= "/HTTP/ s11.sinaimg.cn/mw690/0062amvsty6usbackcg7a&690 "width=" 690 "height=" 329 "name=" Image_operate_ 30141438953592498 "alt=" Redhat partition and Disk Encryption "title=" Redhat partition and Disk Encryption "style=" Margin:0px;padding:0px;border:0px;list-style: none; "/>

Write these three files and use them.

Cryptsetup luksaddkey/dev/vdb1/root/passwd (associating a device with a password)

This allows for power-on self-booting
