| 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. | 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: | 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: | + | 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! | ||
