This tutorial is going to show you a simple trick that you can use to reset your forgotten root password for CentOS 7 servers. Sometimes things happen and you totally forget your password. It happens to the best of us.
This tutorial will only work if you have direct access to the machine (example: You are next to the machine or have KVM\/IPMI)
You can\u2019t reset the root password if you\u2019re remotely connected since you need boot menu access.
If you have a ServerHub Bare Metal Server this shouldn’t be an issue as we offer IPMI completely free with every server we sell.

To get started, turn on the machine that you\u2019ve forgotten the root password on. <\/strong>For CentOS 7 devices, you\u2019ll be given 5 seconds at the boot menu to select the operating system kernel to boot into.<\/p>\n\n\n\n That 5 seconds is important, because allows for \u00a0admins to select different kernels or edit existing kernel parameters before booting.<\/em><\/p>\n\n\n\n At the boot menu, press\u00a0e<\/strong>\u00a0to edit the existing kernel (Core)<\/p>\n\n\n\n Next, scroll down to the list until you see the line underlined below (\u00a0 Change the ro<\/strong> line to rw<\/strong> and add init=\/sysroot\/bin\/sh<\/strong><\/p>\n\n\n\n After changing that, press Control + X<\/strong> or Ctrl + X<\/strong> on your keyboard to start into single user mode using the bash shell specified above. In this mode, we\u2019re going to change the root password.<\/p>\n\n\n\n In the single user mode, run the command as shown below<\/p>\n\n\n\n Finally, run the commands below to change the root password.<\/p>\n\n\n\n You\u2019ll be prompted to create and confirm a new password. After creating the password, run the commands below to update SELinux parameters<\/p>\n\n\n\n Exit and reboot your system. Your password should now be successfully reset!<\/p>\n\n\n\n This tutorial is going to show you a simple trick that you can use to reset your forgotten root password for CentOS 7 servers.
