Create a new security group - I like to dedicate security groups to server types.

Create/Use a key pair for which you have the private key.

Give your instance a meaningful value for the “Name” key.

Default “Advanced Instance Options” should be fine.

Generate a single instance, availability zone probably does not matter, and I am going to run with Micro (Micro is likely sufficient for proof of concept, but I would not recommend using it in a production server).

Use the “Launch Instance” button to get started. The goal is to install a PostgreSQL server on Amazon Linux, and to allow external access to that database server.

It seems likely to me that you want some hybrid of the two versions, but this one will get you up and running in a few minutes.

Some more in-depth installation techniques are in the next post ( Install PostgreSQL 9.0 on Amazon Linux).

The first article will use yum (and the default amazon repositories) for the installation, all defaults, and the ec2 instance EBS root device. I am going to break this into two articles. AWS: Install PostgreSQL on Amazon Linux (quick and dirty)

Postgresql yum install
