Installing Debian Wheezy in Amazon EC2

Installing Debian Wheezy in Amazon EC2

1. Go to the website of debian and look for the official AMIs.

https://wiki.debian.org/Cloud/AmazonEC2Image/Wheezy#A7.2


2. Get the AMI that you want and use it in ec2.

Example: ami-537f1b52


3. Go to the AMI and enter the ami id above in the search field.

4. Select the AMI and click Launch.
