====== Reset the Root Password in Oracle Linux ======

Ever need to reset the password for Root on an Oracle Linux box? You’ve come to the right place! Here’s how:

FYI, I did this tutorial in Oracle Enterprise Linux (OEL) 7, but this is a distro based on Red Hat Enterprise Linux (RHEL), so these instructions should more-or-less work on any similar distro to OEL/RHEL, give or take a few versions.
Let’s get started:
===== Reboot Linux =====

Reboot Linux. When boot menu appears, press a key to stop it from booting any further. You should see something like this:{{ :linux:oel_reset_password_1.gif |}}

===== Press the “e” key and add line =====

Press the “**e**” key on the top line of the menu, and then on the next screen that appears, scroll down to the line that starts with “**linux16**” and  change the end from “…**quiet LANG**…” to “…**quiet rw init=/bin/bash LANG**…” so it’ll look like this: {{ :linux:oel_reset_password_2.gif |}}
<note>It’s fine if you don’t see the “**LANG**…” part after “…**quiet**” – just put the “**rw init=/bin/bash**” after “**quiet**” anyway.</note>

===== Change password =====

At the prompt that appears, type “**passwd**” to change the root password: {{ :linux:oel_reset_password_3.gif |}}

===== SElinux and autolabel option =====

Now, depending on how your system is configured, you may also need to type “**touch /.autorelabel**” to have it perform a SELinux relabel of the disk to allow root login. Try it first without this, and if it doesn’t work, then try it with this (since it can take a while if you have a large disk).

===== Reboot =====
Type “**/usr/sbin/reboot –f**” to reboot.

===== Done =====

After waiting a few minutes for the reboot to finish, you should be able to log in as root with your new password!
