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.

Reset Root Password

Step 1 Restart your system 
Step 2 Press e on your keyboard when you see this screen:


Step 3 If you've done this correctly, you should see a screen similar to this one:




Step 4 Scroll down and find  "linux16" word and use your arrow keys to move to the "linux16" line:




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



Step 11 After successful log out  now you have to enter your new password  for  the root user 



Step 12 Now after successful login open your terminal and type one of the following commands
restorecon /etc/shadow or  touch ./autorelabel



Step 13 Kindly recheck your new password again 😎

If you still face the problem in resetting your root password please checkout the video below.

Fahrenheit to Celsius

-
Level EASY Given three values - Start Fahrenheit Value (S), End Fahrenheit value (E) and Step Size (W), you need to convert all Fahrenheit values from Start to End at the gap of W, into their corresponding Celsius values and print the table. Input Format : 3 integers - S, E and W respectively Output Format : Fahrenheit to Celsius conversion table. One line for every Fahrenheit and corresponding Celsius value. On Fahrenheit value and its corresponding Celsius value should be separate by tab ("\t") Constraints : 0 <= S <= 80 S <= E <= 900 0 <= W <= 40 Sample Input 1: 0 100 20 Sample Output 1: 0 -17 20 -6 40 4 60 15 80 26 100 37 Sample Input 2: 20 119 13 Sample Output 2: 20 -6 33 0 46 7 59 15 72 22 85 29 98 36 111 43 Explanation For Input 2: We need need to start calculating the Celsius values for each of the Fahrenheit Value which starts from 20. So starting from 20 which is the given Fahrenheit start
