In this tutorial, we'll cover the step-by-step process of deploying a multi-tier website on AWS using Amazon EC2 for hosting the website and Amazon RDS for the MySQL database. We'll also set up auto-scaling for high availability and create a load balancer to distribute traffic across multiple instances.
Before you begin, ensure you have:
- An AWS account with appropriate permissions.
- Basic knowledge of AWS services like EC2, RDS, and load balancers.
- Launch an EC2 Instance
- Log in to your AWS Management Console.
- Navigate to EC2 and click on "Launch Instance."
- Choose Ubuntu Server as the AMI.
- Select
t2.microas the instance type. - Create a new key pair (e.g.,
my-keypair) for SSH access and download the private key. - Configure security group (
website-deploy-security-group) to allow all traffic (0.0.0.0/0).
- Install Apache and PHP
sudo apt-get update sudo apt-get install apache2 -y cd /var/www/html sudo rm index.html sudo nano index.php
Add your PHP code in index.php to display a basic webpage.
This HTML and PHP code snippet represents a basic web form that collects user input (name and email) and inserts it into a MySQL database hosted on Amazon RDS. Let's break down the code and provide an overview of its functionality:
<!DOCTYPE html>
<html>
<head>
<title>Simple Form</title>
<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css">
<style>
body {
background-image: url('images/2.png');
background-repeat: no-repeat;
background-size: 100% 100%;
}
</style>
</head>
<body>
<br><br><br><br>
<div class="container">
<div class="jumbotron vertical-center">
<form method="post">
<div class="form-group">
<label for="firstname">Name:</label>
<input type="text" class="form-control" name="firstname">
</div>
<div class="form-group">
<label for="email">Email:</label>
<input type="text" class="form-control" name="email">
</div>
<button type="submit" class="btn btn-success">Submit</button>
</form>
</div>
</div>
</body>
</html>- This HTML form includes Bootstrap styling for layout.
- It contains input fields for
Name(firstname) andEmail. - On form submission (
POSTmethod), it sends data to the same page (actionis not needed as it defaults to the current URL).
<?php
// Retrieve form data
$firstname = $_POST['firstname'];
$email = $_POST['email'];
// Database connection details
$servername = "intelli.coghw13fheqo.us-east-2.rds.amazonaws.com";
$username = "intel";
$password = "intel123";
$dbname = "intel";
// Create connection
$conn = new mysqli($servername, $username, $password, $dbname);
// Check connection
if ($conn->connect_error) {
die("Connection failed: " . $conn->connect_error);
}
// Check if form is submitted
if (isset($_POST['firstname']) && isset($_POST['email'])) {
// SQL query to insert data into database
$sql = "INSERT INTO data (firstname, email) VALUES ('$firstname', '$email')";
// Execute SQL query
if ($conn->query($sql) === TRUE) {
echo "New record created successfully";
} else {
echo "Error: " . $sql . "<br>" . $conn->error;
}
}
// Close database connection
$conn->close();
?>- This PHP script handles the form submission.
- It retrieves the
firstnameandemailvalues from$_POST. - Establishes a connection to the MySQL database using
mysqli. - If form data is submitted (
isset($_POST['firstname']) && isset($_POST['email'])), it constructs an SQL query to insert the data into thedatatable. - Executes the SQL query and displays a success or error message accordingly.
- Closes the database connection after processing.
This code snippet demonstrates a simple web form that captures user input and inserts it into an Amazon RDS MySQL database. Ensure that the database connection details ($servername, $username, $password, $dbname) are correct and match your RDS instance configuration. Additionally, replace 'images/2.png' with the path to your desired background image.
Make sure to handle form validation, error handling, and security considerations (e.g., SQL injection prevention) based on your application requirements.
- Create an RDS Instance
- Navigate to RDS in the AWS Management Console.
- Click on "Create database" and choose MySQL as the engine.
- Configure database details (e.g.,
multi-tier-website-DB). - Set master username and password.
- Connect the RDS instance to the EC2 instance's security group.
- Configure PHP to Connect to RDS
Execute the following SQL commands:
sudo apt-get install mysql-server -y sudo mysql -h multi-tier-website-db.cvwwkjmmcvgi.us-east-1.rds.amazonaws.com -u admin -padmin123
show databases; use intel; create table data(firstname varchar(20), email varchar(20)); insert into data values('AWS', 'aws@support.com'); select * from data;
- Create Load Balancer and Auto Scaling Group
- Create an AMI from the EC2 instance.
- Navigate to EC2 > Instances, select your instance, and click "Actions" > "Image and templates" > "Create image."
- Set up an Application Load Balancer (ALB) in the AWS Management Console.
- Create a target group for instances.
- Configure auto-scaling group with the created AMI and ALB.
- Testing the Setup
- Access the website through the load balancer's DNS.
- Add data to the website and verify database entries.
Congratulations! You've successfully deployed a multi-tier website on AWS using EC2 for web hosting, RDS for database management, and auto-scaling for high availability. Feel free to customize and expand upon this setup based on your project requirements.
