Pre-requisites on the server are Amazon S3 tools, and zip
sudo apt-get install s3cmd
sudo apt-get install zip unzip
You then need to configure the s3cmd to use the Access Code and Secret Key from the IAM within your AWS console. Its recommended that you set up a new user with programmatic access only for each server / project, and give the user the AmazonS3FullAccess permission.
Back on the server, run
sudo s3cmd --configure
Enter your access key, secret key
If, like me you are using EU-West-1 (Dublin) as your datacenter, then type in “eu-west-1” for the Default Region.
Enter a password to encrypt traffic between the EC2 instance and S3 (DO NOT USE YOUR MAIN ACCOUNT PASSWORD, MAKE A NEW ONE)
