How to connect an EC2 instance if you lost your keypair (.pem) file ? Recover AWS keypair

This video is going to be about how to connect or access an EC2 instance in case you lost your private key or the .pem file or you accidentally deleted the file permanently.
What will we do in this video?
- We will Create a new EC2 Linux instance named ‘dev-stage-new’ with a keypair
- Then, we will Access the EC2 instance using the keypair
- Next, we will Delete the keypair (after that, we won’t have the keypair to access the ec2 instance)
- Again, we will Create a new ec2 instance named ‘dev-stage-old’ with a new keypair, and then
- Perform our lab task to access the old EC2 instance whose keypair is already lost or deleted.
So, let’s begin.

Hello, may be you don't know how much your video help me today. It was horrible experience when I accidentally delete the public key from ~/.ssh/authorized_keys and forgot to add the new one. It was locking out myself from the server. I was in huge trouble. Thank you very much from the bottom of my heart.

At 10:00, youve copied and cat keypair to the old volume but the question is what you have copied? if it the temporary instance's keypair youve copied to the old one ?

Hi, the fstype i got is a ext4. when i use the command "mount -o rw, nouuid /dev/xvdf1 /mnt
" got error with "mount: /mnt: wrong fs type, bad option, bad superblock on /dev/xvdf1, missing codepage or helper program, or other error.
". May I know how to solve this? Thank you :)

[saurabhfule]

you should explain the " mount -o rw, nouuid " this command what it will do in detail rather that video is superb

To attach and detach volume We don't have to stop the instanc, Right?

[hassanmir]

You just nailed it, please tell me why did you rename it to xvda1 at last.

[rizwanhawaldar]

Why can't we just create a ami of that server with new key and make that instance live💀 just asking

[progjr]

what if the instance is running on windows?

[durgaprasadandraju]

I followed each and every step in linux not worked. Time waste.
