AWS/EC2 Instance Setup

Amazon web services offers free tier server/cloud space and computing. Though limited by this free tier options, testing can be done to insure a multi-master network will work for SARWAI purposes.

Account Creation and Setup

• An Amazon AWS free tier web service can be setup here: https://aws.amazon.com/free/
• An Ubuntu 16.04 LTS instance is setup
• NOTE: This instance is just the command line terminal and not the GUI. Most GUI setup requires a vpn, which may hurt the integrity of the system. If a GUI option is needed, proceed carefully.

EC2 Setup

• Elastic IP

  • In order to insure a static IP when ssh'd in to the EC2 instace, a static IP must be created

  • From the Menu under NETWORK & SECURITY, choose the Elastic IPs option as show Below

                                                                          ![](/AWS Setup/ElasticIP.jpb)
    

  • From here click the Allocate New Address Button at the top of the page

  • Then Allocate
  • NOTE: This is the address to be used when SSHing into the EC2 instance

• Port Configuration

  • Under NETWORK & SECURITY choose Security Groups

AWS Key

• A Encryption key is needed to access the server

• chmod 600 key.pem

Connecting to the Server

• The connection to the server will be done via SSH
  • Linux Ubuntu 16.04 LTS has ssh capabilities built in
• Using the key given by AWS, we can SSH into the server via the command below. NOTE: The IP used is the elastic IP. Also you must be in the key directory

• ssh -i key.pem ubuntu@<elasticIP>
