🎯 What You Need

Before we dive in, let’s make sure you’re ready! 🎯 Here’s your checklist:

Prerequisites:

• ✅ AlmaLinux 8 or 9 installed and running
• ✅ Root or sudo access (we’ll need admin powers!)
• ✅ Basic terminal knowledge (you can type commands)
• ✅ Internet connection (for downloading packages)
• ✅ About 30 minutes of your time
• ✅ A cup of coffee ☕ (optional but recommended!)
• ✅ Excitement to learn something awesome! 🎉

📝 Step 1: Preparing Your System

Let’s start by getting your system ready! 🎯 This is like preparing your workspace before cooking a great meal.

Update Your System:

# First, update all existing packages - always start fresh!
sudo dnf update -y

# Check your AlmaLinux version
cat /etc/redhat-release
# Output: AlmaLinux release 9.x

# Clean up package cache to free space
sudo dnf clean all

# Check available disk space
df -h
# Make sure you have at least 2GB free

Set Up Firewall Rules:

# Enable firewall if not already active
sudo systemctl enable --now firewalld

# Check firewall status
sudo firewall-cmd --state
# Output: running

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

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

# Add MySQL service (port 3306) - optional for remote access
sudo firewall-cmd --permanent --add-service=mysql

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

# Verify services are added
sudo firewall-cmd --list-services
# Output: cockpit dhcpv6-client http https mysql ssh

🔧 Step 2: Installing Apache Web Server

Time to install Apache - the ‘A’ in LAMP! 🌐 Apache is like the foundation of your house.

Install and Configure Apache:

# Install Apache web server
sudo dnf install httpd -y

# Enable Apache to start automatically
sudo systemctl enable httpd

# Start Apache service
sudo systemctl start httpd

# Check Apache status
sudo systemctl status httpd
# Output: Active (running) - Great! 🎉

# Get your server's IP address
ip addr show | grep inet
# Note your IP address (like 192.168.1.100)

Test Apache Installation:

# Create a test page
echo "<h1>🎉 Apache is Working!</h1>" | sudo tee /var/www/html/test.html

# Set proper permissions
sudo chown apache:apache /var/www/html/test.html

# Test locally
curl http://localhost/test.html
# Output: <h1>🎉 Apache is Working!</h1>

Now open your browser and visit: http://YOUR_SERVER_IP/test.html - You should see your message! 🎊

🌟 Step 3: Installing MySQL/MariaDB Database

Let’s install MariaDB (MySQL’s cousin) - the ‘M’ in LAMP! 💾 This is where all your data will live.

Install MariaDB:

# Install MariaDB server and client
sudo dnf install mariadb-server mariadb -y

# Enable MariaDB to start automatically
sudo systemctl enable mariadb

# Start MariaDB service
sudo systemctl start mariadb

# Check MariaDB status
sudo systemctl status mariadb
# Output: Active (running) - Perfect! 💪

Secure MariaDB Installation:

# Run security script
sudo mysql_secure_installation

# You'll see prompts - here's what to answer:
# Enter current password for root: [Press Enter - no password yet]
# Set root password? [Y/n]: Y
# New password: [Enter a strong password]
# Re-enter password: [Confirm password]
# Remove anonymous users? [Y/n]: Y
# Disallow root login remotely? [Y/n]: Y
# Remove test database? [Y/n]: Y
# Reload privilege tables? [Y/n]: Y

Test Database Connection:

# Connect to MariaDB
sudo mysql -u root -p
# Enter your root password

# Once connected, run these commands:
MariaDB [(none)]> SELECT VERSION();
# Shows MariaDB version

MariaDB [(none)]> SHOW DATABASES;
# Lists all databases

MariaDB [(none)]> CREATE DATABASE test_lamp;
# Creates a test database

MariaDB [(none)]> EXIT;
# Exit MariaDB

✅ Step 4: Installing PHP

Time for PHP - the ‘P’ in LAMP! 🐘 This is what makes your websites dynamic and interactive.

Install PHP and Extensions:

# Install PHP and common extensions
sudo dnf install php php-mysqlnd php-fpm php-opcache php-gd php-xml php-mbstring -y

# Install additional useful PHP extensions
sudo dnf install php-json php-zip php-curl php-intl -y

# Check PHP version
php -v
# Output: PHP 8.x.x - Awesome! 🎯

# Restart Apache to load PHP
sudo systemctl restart httpd

Create PHP Info Page:

# Create a PHP info file
echo "<?php phpinfo(); ?>" | sudo tee /var/www/html/info.php

# Set proper ownership
sudo chown apache:apache /var/www/html/info.php

# Test PHP from command line
php -r "echo 'PHP is working! 🎉';"
# Output: PHP is working! 🎉

Visit http://YOUR_SERVER_IP/info.php in your browser - you’ll see detailed PHP information! 🔍

🎮 Quick Examples

Let’s create some real-world examples to test your LAMP stack! 🚀
