AWS/EC2: Changing PEM files

Hello, happy campers!

I had an instance that I could no longer find it's PEM file, so I totally freaked out and curled in a fetal position and started sobbing but then the Oracle helped me.


This post here did the trick: http://blog.celingest.com/en/2013/11/14/replace-lost-keypair-ec2-instance/


I just had to do one little change because the instance to be jacked wasn't using a EC2-USER but a ROOT user, so on this step:


cat /home/ec2-user/.ssh/authorized_keys > /mnt/recovery/home/ec2-user/.ssh/authorized_keys


I had to change it a bit, to this:


cat /home/ec2-user/.ssh/authorized_keys > /mnt/recovery/root/.ssh/authorized_keys

And Yippie kay-yay!

Cheers.
