How to do SSH in AWS EC2 instance? - [ Ссылка ]
In this lab session, we are going to launch and set up an EC2 instance on AWS. Along with that, we are going to create public and private key pairs for the EC2 instance so that we can SSH into an EC2 instance.
Typically there are two ways to generate the key-pair for an Ec2 instance on AWS -
1. Download the private key file(pem) from AWS itself at the time of launching an EC2 instance
2. Create your key pair(public key, private key) and associate those keys to launch the EC2 instance.
The first way is a little easy but you do not have very good control over the key generation. You have to rely on AWS to issue the key and use that key going forward. In case if you lose or misplace the key then it is impossible to SSH into your EC2 instance.
The Second is in which you can generate your key-pair(public, private keys) and add the public key to AWS manually by uploading it. And then use the private key to SSH into your EC2 instance. The only advantage which you have over here is you get complete control over the key generation part. Later on, you can use some secure channel to distribute the keys to other peer developers.
