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.

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 ?

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.

[@Enkripsan]

Most welcome

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 :)

[@Enkripsan]

you can create the mount point directory in a different name and mount the drive to the directory...hope it works !

[@jwk05003]

same exact problem for me. This command was my workaround "mount /dev/xvdf1 /mnt"

[@roshangamer6811]

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

[@bandwidthbucks]

I think you have not watched it carefully

[@madhanops]

I'm not getting bro.. pls explain ​@@bandwidthbucks

[@bandwidthbucks]

@@madhanops Bro watch this video 9 months ago right, you would have watch this lot many times, still you don't understand. Okay let it be its a best practise to stop and then detach the volume for safer side.

[@hassanmir5309]

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

[@kondisettynarender3290]

because it is root volume.

[@madhavan.g4187]

Great job bro. Carry on.

[@Enkripsan]

Thanks

[@djangodeveloper2973]

the video is very helpful. thanks.

[@saurabhfule4295]

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

[@Enkripsan]

Thanks for the idea!

[@jwk05003]

Thank you!

[@andukurinaveenkumar3760]

awesome dude

[@rizwanhawaldar2567]

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

[@Enkripsan]

Yeah, you can do that as an other way.

[@progjr1062]

what if the instance is running on windows?

[@Enkripsan]

Need to check.

[@legend3001]

hii sir at last step when i am going to attach volume it is not showing new instance how to rectify it . please explain me . it is showing same availability zones only displayed here. how to fix this sir.

[@Enkripsan]

Availability zone must be the same. If you are trying to attach to the different availability zone, it may not show you.
