CentOS / RHEL 7 : How to Reset root password

Hey, everyone😀, I am Svastikkka when we are a beginner in Linux or we just started to use Linux operating system we always thought what if we forget the password of our Linux account it may be a root account or any other user-defined account so in here I am going to show that "how to reset the root password of Linux operating system account". Also, it is important for the system administrator to know how to reset the root password.
We consider RedHat operating system (RHEL7) to demonstrate how to reset the root password.

Step 5 In the last "linux16" line append rd.break enforcing=0

Step 6 Press Ctrl-x to start and the system will go in emergency mode.

Step 7 In the emergency mode remount the hard drive with read-write access:  #mount –o remount,rw /sysroot

Step 8 Run chroot to access the system: #chroot /sysroot

Step 9 You can now change the root password: #passwd root

After successful submission, you see authentication is successfully updated 

Step 10 Type exit twice to reboot the system. #exit
