Theodoros Emmanouilidis » Blog Archive Install nginx Τo Amazon Linux AMI – Theodoros Emmanouilidis
Since Amazon offers its Amazon Linux AMI for free if used with a micro instance, it is a nice idea to use such a micro instance as a reverse proxy front-end for your actual web server. This setup offers many advantages, with enhanced security and fail over capabilities being two of them.

1)Set up AMI
You have to select an Amazon Linux AMI to run as a micro instance. Store the Key Pair in order to be able to login to the machine and associate an elastic IP to it. Then alter the default security group opening port 80 and 443 to the world and 22 to the IP / IPs you will use to connect via ssh to the machine.
2)Login and become root
By default you can login to the machine via ssh using as user name “ec2-user” and the Key Pair that you downloaded upon AMI creation. In order to continue the installation it is convenient to became root. Type
