HOWTO: Installing Vault On AWS Linux

This is quick howto for installing vault on AWS Linux, mostly to remind myself. At the end of this tutorial, you'll have a working vault server, using s3 for the backend, self signed certificates for tls, and supervisord to ensure that the vault server is always running, and starts on reboot.

Setting up S3

First things first, let's set up an s3 bucket to use as the storage backend for our s3 instance.

1. From the AWS Mangement Console, go to the S3 console.

2. Click on the Create Bucket button
