How To Reset The Forgotten Root Password On CentOS 7

 

Hello there,

In this article, I will show you the server I used recently and forgot the password. I used Centos7 as the operating system.

First off, let’s shut down our server. Then, at the bottom of the opening screen, ”   Press ‘e’ to edit the selected item or ‘c’ for a command prompt.” Let’s look at the part.

Let’s press ‘e’ ıp and continue.

 

Centos_Linux
Centos_Linux

Let’s go down with the arrow directions on the screen and find the relevant line.

 

Centos_Linux_1

 

Delete the ro part you see on the screen (linux16 / vmlinuz the end of the line)

 

Centos_Linux_2

 

We write rw init = / sysroot / bin / sh and change it. It then exit this section with the Ctrl + x key combination.

 

Centos_Linux_3

 

In this screen;

chroot /sysroot

passwd root

you can enter your new password…

 

Centos_Linux_4

 

Finally, due to selinux settings, you should enter the following command. In this way, the new password will be active-tagged. At the command prompt, commands such as reboot-shutdown will not work. Don’t forget to exit chroot.

I hope it has been a useful article.
