Post-Install

Set JAVA_HOME

Set JAVA_HOME for all accounts that are going to use ec2 tools.

For all users that are going to use it, configure the following environment variables in their .bashrc (or equivalent):

export EC2_HOME=/opt/ec2-api-tools
export PATH=${PATH}:${EC2_HOME}/bin

Set the Access Keys

Provision the API access keys for the Amazon IAM user that will use the API. More details about access keys here: Amazon AWS API Access Keys.

Access keys can be specified on command line every time an ec2 command is issued, with:

-aws-access-key or -O
--aws-secret-key or -W 

or by setting the following environment variables:

export AWS_ACCESS_KEY=your-aws-access-key-id 
export AWS_SECRET_KEY=your-aws-secret-key

Test Installation

ec2-describe-regions

Set the Region

export EC2_URL=https://<service_endpoint>  

Example:

export EC2_URL=https://ec2.us-west-2.amazonaws.com

Note: For some reason, the console always shows by default "Oregon", which corresponds to https://ec2.us-west-2.amazonaws.com.
