Now that our EC2 and database are set up, we need to actually connect to the server so that we can do what we set out to do: install Ghost!
There are a few ways that EC2 lets you connect but we will be using the SSH client. To do so, you'll need to find your ssh key file, modify the file permissions, and we will use that key file in combination with the public DNS of the EC2 server to SSH into the server. Since our own IP address is explicitly allowed we will be able to do so!
