Café Online Ordering System Overview This repository contains the setup and configuration for a dynamic website for the café that allows customers to place online orders. The website is hosted on Amazon EC2 instances, and it includes a backend using MySQL, PHP, and a web server (Apache). The system also leverages AWS Secrets Manager to store sensitive credentials and AWS Cloud9 for development.
Features
Online Ordering: Customers can view the café menu and place orders.
Order History: Staff can view a history of all orders placed.
Dynamic Website: The website supports dynamic content, including customer orders and menu management.
Disaster Recovery: The system is set up in multiple AWS Regions to ensure high availability and disaster recovery.
Architecture
AWS EC2 Instances: Used to host the website in different AWS Regions (Development in us-east-1 and Production in us-west-2).
AWS Secrets Manager: Manages the sensitive configuration settings such as database credentials.
AWS Cloud9: Provides the development environment for managing and deploying the café website.
LAMP Stack: Apache, MySQL, and PHP are used for the web application and database.
Installation
Prerequisites
An AWS account
AWS CLI installed and configured
SSH key pair (for connecting to EC2 instances)
Steps to Deploy
Launch EC2 Instances:
Launch EC2 instances in your chosen AWS regions.
Configure security groups to allow HTTP and SSH access.
Use the Cloud9 IDE for accessing and managing your EC2 instances.
Set up the LAMP stack:
Install Apache and MySQL on the EC2 instances:
bash
Copy code
sudo yum install httpd
sudo service httpd start
sudo yum install mariadb-server
sudo service mariadb start
Install PHP:
Install PHP on the EC2 instance:
bash
Copy code
sudo yum install php php-mysql
Download and Configure the Application:
Download the application setup files:
bash
Copy code
wget # Replace with actual file URL
unzip setup.zip
Set up the database:
bash
Copy code
cd db/
./set-root-password.sh
./create-db.sh
Update the PHP configuration:
bash
Copy code
sudo sed -i "2i date.timezone = "America/New_York" " /etc/php.ini
sudo service httpd restart
Set up AWS Secrets Manager:
Create the necessary parameters in AWS Secrets Manager:
bash
Copy code
cd environment/setup/
./set-app-parameters.sh
Test the Website:
Open the website in a browser:
url
Copy code
http:///cafe
Creating an AMI and Deploying to a New Region
Create an AMI:
From the EC2 Console, select the instance and create an AMI image.
Launch an Instance in Another Region:
Launch a new EC2 instance in the desired AWS region (e.g., Oregon).
Use the AMI from the previous step to launch the new instance.
Configure Secrets in the New Region:
Update the set-app-parameters.sh script with the new region and instance DNS.
Run the script to configure the secrets in Secrets Manager for the new instance.
Test the Production Environment:
Open the website in a browser for the new instance’s public IP.
Troubleshooting
Website not loading:
Ensure the web server and database are running.
Check security group settings to ensure HTTP/HTTPS access is allowed.
Ensure the AWS Secrets Manager has the correct parameters set.
Order functionality not working:
Verify that the database is correctly set up with required tables and data.
Check the PHP configuration and logs for any errors.
Conclusion
This project sets up a dynamic online ordering system for the café that can scale across multiple AWS regions for development and production environments. The architecture ensures high availability and disaster recovery.
