ELB-EC2-DB

This is an example of ELB and 2 EC2 phpapps, and one DB MySQL server

• The EC2's are now based on ubuntu 14.04 AMI

• Web Server is nginx

• The output of the terraform apply will display the web ip address

Config

This presumes that there is a file in your home directory ~/.aws/credentials.tfvar that looks like:

access_key = "AKIblaBLaBlABLA"

secret_key = "wQh1blaBLAblAbLaBLAbla"

region = "us-west-2"

To build the Terrafrom run:

terraform apply -var-file="~/.aws/credentials.tfvar"
  AWS_DEFAULT_REGION='us-west-1' terraform apply -auto-approve -var-file="~/.aws/credentials.tfvar"

the AWS_DEFAULT_REGION keeps it so you don't have to keep answering the input question of "what region"

1 Private subnet

1 Public subnet

2 security groups - Web App and Database

2 EC2s

Apache HTTP Server

MySQL Instance

MySQL - create TABLE mytable and insert an entrie Once the simple1 stack is complete:

find the Public IP address:

aws ec2 describe-instances|grep PublicIp

run a command in your browser to read from the database: http://PublicIpAddress/calldb.php

Log into the phpapp server and run host mydatabase.libratech.internal responce: host mydatabase.libratech.internal

Notes: ec2.tf This line is required in order to get the DB EC2 system to have a Gateway Internet Access depends_on = ["aws_route_table_association.PrivateAZA"]
