Abstract

The present invention provides a password reset method and system based on Linux, comprising: S1, mounting the drive letter of the mobile device to / mnt; S2, writing grub into the mobile device; S3, resetting the password Write the script into the initramfs.img file to generate a new initramfs.img file; S4, copy the initramfs.img file containing the password reset script into the mobile device. S5. Modify the initramfs boot file of the grub.cfg file in the mobile device to be a newly generated initramfs.img file. In the present invention, a password reset script is built into a mobile device such as a U disk. When the user forgets the system password and needs to reset the password, he or she chooses to boot from the U disk mobile device, and the built-in password reset script automatically runs to complete reset Password. Users do not need to remember the complex operation of repeatedly trying or modifying the grub kernel startup parameters to enter the shell interface to reset the password. They only need to start the reset from the preset U disk mobile device, which reduces the memory burden of the user and simplifies the heavy operation. The process of setting a password is convenient for the user to reset the password.

Description

technical field [0001] The invention relates to the technical field of password reset, in particular to a Linux-based password reset method and system. Background technique [0002] In the Linux system, if the user forgets the password, or tries repeatedly through memory, or needs to use the CD-ROM rescue mode, or modify the grub kernel startup parameters to enter the shell interface to reset the password. Modifying the grub kernel startup parameters requires 9 steps to complete the password reset operation. [0003] The specific operation of modifying the grub kernel startup parameters is as follows: [0004] In the startup grub menu, select the edit option to start; when the system starts to the grub interface, press the e key to enter the editing interface, enter rd.break at the end of the line in Linux 16, and press Ctrl+x to start the system; in the shell interface after startup , remount the file system for reading and writing; set the root directory; modify the root...
