Editing Enabling SSH Connections to an Elastic Beanstalk Environment (section)

=== Key Pairs ===

Create a key pair on an EC2 instance after creating an inbound rule for the SSH port.

* '''EC2 Management Console''' > ''select the EC2 instance linked to the EBS environment''
* '''Network & Security''' group (on lefthand menu) > '''Key Pairs'''
* '''Create Key Pair''' button at the top right
** '''Name:''' ''descriptive token''
** '''Key pair type:''' RSA
** '''File Format:''' `.pem`
** Click '''Create'''
** Download the `.pem` file to `~/.ssh/`
** ''(If the certificate file downloads with a ".cer" extension, it is still in .pem format. It is ok to simply change the extension from ".cer" to ".pem".)''
* After the `.pem` file is installed in the `~/.ssh/` directory, make sure its permissions are set to `700`.

Link an EBS environment with a key pair. 

* '''EB Management Console''' > ''application'' > ''environment''
* '''Configuration''' > '''Security''' > '''Edit''' 
* '''Key Pair''': Select the key pair created for the EC2 instance.

At this point, the server should be ready to accept ssh connections.

<p class="alert alert-warning">An existing key pair cannot be associated with an existing EC2 instance. Well, they can, but it may be simpler to create a new Elastic Beanstalk and a new EC2 instance along with it.</p>
