    This is a collection of scripts used to demonstrate how to get started with Google Cloud SQL.
Follow the step by step procedures in this video: Getting Started with Google Cloud SQL
Prerequisites:


Sign up for Google Cloud SQL, if you haven't already.


Download and install MySQL Community Server which includes the MySQL Command-line client tool.

MySQL Command-line client settings:

host: IP address (shown in video)
port: 3306 (normal)
configuration: nothing special other than MySQL Command-line client installed


Download and Install the gcutil command line tool. This will be used for interacting with a Google Compute Engine VM instance in order to connect it to Cloud SQL.


Inventory of scripts:
SQL script to create a MySQL database and populate it with sample data:

schema_and_data.sql : This will be run from the MySQL command line client tool.

Setup scripts for installing PHP and phpMyAdmin on a Compute Engine VM:

setup-php.sh : Install the software necessary to serve PHP pages from a Compute Engine VM.
setup-phpmyadmin.sh : Install the software necessary to run phpMyAdmin on a Compute Engine VM.

Example PHP Pages:

index-gce.php : Example PHP page running on Compute Engine that connects to a Cloud SQL instance.
index-appengine.php : Example PHP page running on App Engine that connects to a Cloud SQL instance.


## index-appengine.php
