🔧 Step 2: Install Apache Web Server

Apache is the “A” in LAMP - let’s install the world’s most popular web server! 🌐

# Install Apache HTTP Server
sudo dnf install -y httpd

# Start Apache service
sudo systemctl start httpd

# Enable Apache to start automatically on boot
sudo systemctl enable httpd

# Check Apache status
sudo systemctl status httpd

Expected Output:

● httpd.service - The Apache HTTP Server
   Loaded: loaded (/usr/lib/systemd/system/httpd.service; enabled)
   Active: active (running) since Mon 2025-09-14 10:00:00 UTC

Configure Firewall for Apache

# Open HTTP port (80) in firewall
sudo firewall-cmd --permanent --add-service=http

# Open HTTPS port (443) in firewall
sudo firewall-cmd --permanent --add-service=https

# Reload firewall to apply changes
sudo firewall-cmd --reload

# Verify firewall rules
sudo firewall-cmd --list-services

Test Apache Installation

# Test Apache locally
curl http://localhost

# Check from web browser
echo "🌐 Open your browser and visit: http://your-server-ip"
echo "You should see the Apache welcome page!"

Excellent! 🚀 Apache is running and serving web pages!

🌟 Step 3: Install MySQL Database Server

MySQL is the “M” in LAMP - let’s install the powerful database system! 🗄️

# Install MySQL server
sudo dnf install -y mysql-server

# Start MySQL service
sudo systemctl start mysqld

# Enable MySQL to start automatically on boot
sudo systemctl enable mysqld

# Check MySQL status
sudo systemctl status mysqld

Secure MySQL Installation

# Run MySQL security script
sudo mysql_secure_installation

# Follow these prompts:
# - Set root password: YES (choose a strong password)
# - Remove anonymous users: YES
# - Disallow root login remotely: YES
# - Remove test database: YES
# - Reload privilege tables: YES

Test MySQL Connection

# Connect to MySQL as root
sudo mysql -u root -p

# Inside MySQL prompt, run these commands:
# SHOW DATABASES;
# CREATE DATABASE testdb;
# SHOW DATABASES;
# EXIT;

Expected Output:

mysql> SHOW DATABASES;
+--------------------+
| Database           |
+--------------------+
| information_schema |
| mysql              |
| performance_schema |
| sys                |
| testdb             |
+--------------------+

Amazing! 🎯 MySQL is running and ready for your applications!

✅ Step 4: Install PHP

PHP is the “P” in LAMP - let’s install the dynamic scripting language! 🐘

# Install PHP and essential modules
sudo dnf install -y php php-mysqlnd php-fpm php-opcache php-gd php-xml php-mbstring php-json php-curl

# Install additional useful PHP modules
sudo dnf install -y php-zip php-intl php-ldap php-soap

# Check PHP version
php -v

# Start PHP-FPM service
sudo systemctl start php-fpm
sudo systemctl enable php-fpm

Expected Output:

PHP 8.0.30 (cli) (built: Aug  3 2023 18:02:36) ( NTS gcc x86_64 )
Copyright (c) The PHP Group
Zend Engine v4.0.30, Copyright (c) Zend Technologies

Configure Apache for PHP

# Restart Apache to load PHP module
sudo systemctl restart httpd

# Create a PHP info test file
sudo bash -c 'cat > /var/www/html/info.php << EOF
<?php
phpinfo();
?>
EOF'

# Test PHP installation
curl http://localhost/info.php | grep "PHP Version"

# Or visit in browser: http://your-server-ip/info.php

Perfect! ✅ PHP is integrated with Apache and working!

🔧 Step 5: Configure LAMP Stack

Let’s optimize our LAMP stack configuration for better performance! ⚡

Apache Configuration

# Edit Apache main configuration
sudo nano /etc/httpd/conf/httpd.conf

# Key settings to verify/adjust:
# ServerName your-domain.com:80
# DirectoryIndex index.html index.php
# AllowOverride All (for .htaccess support)

# Create custom Apache configuration
sudo bash -c 'cat > /etc/httpd/conf.d/lamp.conf << EOF
# Custom LAMP Configuration
<Directory /var/www/html>
    AllowOverride All
    Require all granted
</Directory>

# Security headers
Header always set X-Content-Type-Options nosniff
Header always set X-Frame-Options DENY
Header always set X-XSS-Protection "1; mode=block"
EOF'

PHP Configuration

# Backup original PHP configuration
sudo cp /etc/php.ini /etc/php.ini.backup

# Edit PHP configuration for better performance
sudo nano /etc/php.ini

# Key settings to adjust (search for these directives):
# memory_limit = 256M
# upload_max_filesize = 64M
# post_max_size = 64M
# max_execution_time = 300
# max_input_vars = 3000
# date.timezone = America/New_York (set your timezone)

MySQL Configuration

# Edit MySQL configuration for better performance
sudo nano /etc/my.cnf.d/mysql-server.cnf

# Add these settings under [mysqld] section:
# innodb_buffer_pool_size = 1G
# max_connections = 200
# query_cache_type = 1
# query_cache_size = 64M

Restart All Services

# Restart all LAMP services to apply configurations
sudo systemctl restart httpd
sudo systemctl restart mysqld
sudo systemctl restart php-fpm

# Verify all services are running
sudo systemctl status httpd mysqld php-fpm

Fantastic! 🎉 Your LAMP stack is optimized and ready!

🌟 Step 6: Create Your First Web Application

Let’s build a real web application to test our LAMP stack! 🎮

Create Database and User

# Connect to MySQL
sudo mysql -u root -p

# Create database and user for our application
# Inside MySQL prompt:

CREATE DATABASE webapp;
CREATE USER 'webuser'@'localhost' IDENTIFIED BY 'webpass123';
GRANT ALL PRIVILEGES ON webapp.* TO 'webuser'@'localhost';
FLUSH PRIVILEGES;

USE webapp;
CREATE TABLE users (
    id INT AUTO_INCREMENT PRIMARY KEY,
    name VARCHAR(100) NOT NULL,
    email VARCHAR(100) NOT NULL UNIQUE,
    created_at TIMESTAMP DEFAULT CURRENT_TIMESTAMP
);

INSERT INTO users (name, email) VALUES 
('John Doe', '[email protected]'),
('Jane Smith', '[email protected]'),
('Bob Wilson', '[email protected]');

EXIT;

Create PHP Application

# Create application directory
sudo mkdir -p /var/www/html/myapp

# Create database connection file
sudo bash -c 'cat > /var/www/html/myapp/config.php << EOF
<?php
$servername = "localhost";
$username = "webuser";
$password = "webpass123";
$dbname = "webapp";

try {
    $pdo = new PDO("mysql:host=$servername;dbname=$dbname", $username, $password);
    $pdo->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
} catch(PDOException $e) {
    die("Connection failed: " . $e->getMessage());
}
?>
EOF'

# Create main application file
sudo bash -c 'cat > /var/www/html/myapp/index.php << EOF
<?php
require_once "config.php";

// Handle form submission
if ($_POST["action"] == "add" && !empty($_POST["name"]) && !empty($_POST["email"])) {
    $stmt = $pdo->prepare("INSERT INTO users (name, email) VALUES (?, ?)");
    $stmt->execute([$_POST["name"], $_POST["email"]]);
    $message = "User added successfully!";
}

// Fetch all users
$stmt = $pdo->query("SELECT * FROM users ORDER BY created_at DESC");
$users = $stmt->fetchAll();
?>
