RHEL 7 Password recovery procedure.

Share this link

Everybody thinks the password recovery procedure in RHEL 7 is simple. But it is not.

To start with, there are several procedures spread all over the Internet. All are slightly different, all are supposed to run in all situations, with physical server and virtual machine. They aren’t.

Then, a RHCSA candidate not only has to know the procedure, he also has to be quick: wasting several minutes waiting for the autorelabel to run is not very efficient. Some enhancements exist to avoid this pitfall.

Finally, failure is not an option: several RHCSA candidates have experimented what it means to receive a zero score because they couldn’t make it.

Test this RHEL 7 password recovery procedure many times. Learn it by heart.
If something doesn’t work as expected, report it, even though it has been already tested hundred times by many people.
