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 | grep hadoop-ec2-images
- verify that a list of images is printed out.
