Creating an EC2 Instance refers to the action of starting a server on Amazon using one's credential, and then connecting to it using ssh.



Method #1: Using the AWS Console

Steps

The steps are fairly simple:

  • Connect to the AWS console, and then select Amazon EC2
  • Click on Launch Instance
  • When the instance is created, right click on it and click on Connect

  • Copy/Paste the ssh command into a shell that you will have started
 ssh -i dft.pem root@ec2-174-129-165-180.compute-1.amazonaws.com
  • Make sure you have downloaded a private key file to your .ssh directory first. This is done by
    • Selecting your account
    • clicking on Credentials
    • selecting the X.509 certificate tab
    • and clicking on Create New. A page will open allowing you to download your pem files. One will be the private key, of the form pk-WMxxxxxxxxxx.pem, the other the certicifcate, of the form cert-WMxxxxxxxxxx.pem. Both should be put in your .ssh dirctory.

Method #2: Using the EC2 Tools

Steps

  • Download the EC2 Tools
  • install them in ~/bin/ec2-api-tools
  • Download the pem files containing your private key and certificate from the Amazon EC2 page (see step above)
  • Modify your .bash_profile file and set several variables:


PATH=$PATH:/Users/thiebaut/bin/ec2-api-tools/bin

# Amazon AWS/EC2 tools 
export EC2_HOME=/Users/thiebaut/bin/ec2-api-tools
export JAVA_HOME=/System/Library/Frameworks/JavaVM.framework/Home
export EC2_PRIVATE_KEY=~/.ssh/pk-WMW2M4ZVFMCZJXSXJN4D7ZS4RMTBJ7VV.pem
export EC2_CERT=~/.ssh/cert-WMW2M4ZVFMCZJXSXJN4D7ZS4RMTBJ7VV.pem
  • Source the .bash_profile file
source .bash_profile
  • Test the ec2 tools:
ec2-describe-images -a

		i386	machine	aki-a71cf9ce	ari-a51cf9cc		instance-store
