🌐 Apache Web Server Installation on AlmaLinux: Complete Setup Guide

Ready to power your websites with the world’s most popular web server? 🚀 Today we’ll install and configure Apache HTTP Server on AlmaLinux - the backbone of over 30% of all websites worldwide! Whether you’re hosting a personal blog, business website, or enterprise application, this guide makes Apache setup simple and secure! 🎯

🤔 Why is Apache on AlmaLinux Important?

Apache HTTP Server on AlmaLinux delivers incredible benefits:

📌 World’s #1 web server - Powers millions of websites including major enterprises
🔧 Enterprise stability - Rock-solid performance with AlmaLinux’s reliability
🚀 Free and open source - No licensing costs, complete freedom
🔐 Advanced security - SSL/TLS support and comprehensive security modules
⭐ Perfect flexibility - Supports PHP, Python, Perl, and virtually any web technology

🎯 What You Need

Before installing Apache on AlmaLinux:

✅ AlmaLinux 9 system (server or desktop)
✅ Root or sudo access
✅ At least 1GB RAM (2GB+ recommended for production)
✅ 5GB+ free disk space
✅ Basic command line knowledge (we’ll guide you!)

📝 Step 1: Install Apache Web Server

Let’s get Apache installed and running! 🛠️

Update System and Install Apache

# Update system packages first
sudo dnf update -y

# Install Apache HTTP Server
sudo dnf install -y httpd

# Install additional useful Apache modules
sudo dnf install -y httpd-tools httpd-manual

# Verify Apache installation
httpd -v
# Apache/2.4.53 (AlmaLinux)

# Check installed Apache modules
httpd -M | head -10

echo "✅ Apache HTTP Server installed successfully!"

Start and Enable Apache Service

# Start Apache service
sudo systemctl start httpd

# Enable Apache to start at boot
sudo systemctl enable httpd

# Check Apache service status
sudo systemctl status httpd

# Verify Apache is listening on port 80
sudo ss -tlnp | grep :80

# Test Apache from command line
curl -I http://localhost

echo "✅ Apache web server is running on port 80!"

Pro tip: 💡 Apache automatically creates the /var/www/html directory for your website files!

🔧 Step 2: Configure Firewall for Web Traffic

Allow HTTP and HTTPS traffic through the firewall:

Open Web Ports in Firewall

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

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

# Alternative: Allow specific ports
# sudo firewall-cmd --permanent --add-port=80/tcp
# sudo firewall-cmd --permanent --add-port=443/tcp

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

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

# Check if ports are open
sudo firewall-cmd --query-service=http
sudo firewall-cmd --query-service=https

echo "✅ Firewall configured for web traffic!"

Test Apache Access

# Get server IP address
IP_ADDRESS=$(ip route get 1.1.1.1 | awk '{print $7; exit}')
echo "Your server IP: $IP_ADDRESS"

# Test from local machine
curl -I http://localhost

# Test Apache default page
curl http://localhost

# Access from browser
echo "Open browser and visit: http://$IP_ADDRESS"
echo "You should see the Apache test page!"

echo "✅ Apache is accessible from the web!"

🌟 Step 3: Create Your First Website

Set up your website with custom content:

Create Website Content

# Navigate to web root directory
cd /var/www/html

# Create a sample homepage
sudo tee index.html << 'EOF'
<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>Welcome to My AlmaLinux Server</title>
    <style>
        body { font-family: Arial, sans-serif; margin: 50px; background: #f4f4f4; }
        .container { background: white; padding: 30px; border-radius: 10px; box-shadow: 0 0 10px rgba(0,0,0,0.1); }
        h1 { color: #2c3e50; }
        .info { background: #ecf0f1; padding: 15px; border-radius: 5px; margin: 20px 0; }
    </style>
</head>
<body>
    <div class="container">
        <h1>🚀 Welcome to My AlmaLinux Apache Server!</h1>
        <p>Congratulations! Apache HTTP Server is running successfully on AlmaLinux.</p>
        <div class="info">
            <h3>Server Information</h3>
            <p><strong>OS:</strong> AlmaLinux 9</p>
            <p><strong>Web Server:</strong> Apache HTTP Server</p>
            <p><strong>Status:</strong> ✅ Online and Ready!</p>
        </div>
        <p>You can now upload your website files to <code>/var/www/html</code></p>
    </div>
</body>
</html>
EOF

# Create a simple PHP info page
sudo tee info.php << 'EOF'
<?php
// PHP Information Page
phpinfo();
?>
EOF

# Set proper ownership and permissions
sudo chown -R apache:apache /var/www/html
sudo chmod -R 644 /var/www/html/*
sudo find /var/www/html -type d -exec chmod 755 {} \;

# Test the new website
curl http://localhost

echo "✅ Custom website created successfully!"

Install PHP Support (Optional)

# Install PHP and common modules
sudo dnf install -y php php-cli php-fpm php-mysqlnd php-curl php-gd php-mbstring php-xml

# Restart Apache to load PHP
sudo systemctl restart httpd

# Test PHP functionality
curl http://localhost/info.php

# Remove PHP info file for security
sudo rm /var/www/html/info.php

echo "✅ PHP support added to Apache!"

✅ Step 4: Configure Apache Virtual Hosts

Set up multiple websites on one server:

Create Virtual Host Directory Structure

# Create directories for virtual hosts
sudo mkdir -p /var/www/example.com/html
sudo mkdir -p /var/www/testsite.local/html
sudo mkdir -p /etc/httpd/sites-available
sudo mkdir -p /etc/httpd/sites-enabled

# Create sample content for first site
sudo tee /var/www/example.com/html/index.html << 'EOF'
<!DOCTYPE html>
<html>
<head>
    <title>Example.com - Powered by Apache on AlmaLinux</title>
</head>
<body>
    <h1>🌟 Welcome to Example.com</h1>
    <p>This is the first virtual host on our Apache server!</p>
    <p>Server powered by AlmaLinux and Apache HTTP Server</p>
</body>
</html>
EOF

# Create sample content for second site
sudo tee /var/www/testsite.local/html/index.html << 'EOF'
<!DOCTYPE html>
<html>
<head>
    <title>Test Site - Apache Virtual Host</title>
    <style>body { background-color: #e8f4f8; font-family: Arial; }</style>
</head>
<body>
    <h1>🧪 Test Site Virtual Host</h1>
    <p>This is a second website on the same Apache server!</p>
    <p>Multiple sites, one powerful AlmaLinux server ⚡</p>
</body>
</html>
EOF

echo "✅ Virtual host directories and content created!"

Configure Virtual Host Files

# Create virtual host configuration for example.com
sudo tee /etc/httpd/sites-available/example.com.conf << 'EOF'
<VirtualHost *:80>
    # Server identification
    ServerName example.com
    ServerAlias www.example.com
    DocumentRoot /var/www/example.com/html
    
    # Logging
    ErrorLog /var/log/httpd/example.com_error.log
    CustomLog /var/log/httpd/example.com_access.log combined
    
    # Directory permissions
    <Directory /var/www/example.com/html>
        AllowOverride All
        Require all granted
    </Directory>
</VirtualHost>
EOF

# Create virtual host configuration for testsite.local
sudo tee /etc/httpd/sites-available/testsite.local.conf << 'EOF'
<VirtualHost *:80>
    # Server identification
    ServerName testsite.local
    ServerAlias www.testsite.local
    DocumentRoot /var/www/testsite.local/html
    
    # Logging
    ErrorLog /var/log/httpd/testsite.local_error.log
    CustomLog /var/log/httpd/testsite.local_access.log combined
    
    # Directory permissions
    <Directory /var/www/testsite.local/html>
        AllowOverride All
        Require all granted
    </Directory>
</VirtualHost>
EOF

# Enable virtual hosts by creating symbolic links
sudo ln -s /etc/httpd/sites-available/example.com.conf /etc/httpd/sites-enabled/
sudo ln -s /etc/httpd/sites-available/testsite.local.conf /etc/httpd/sites-enabled/

# Set proper ownership
sudo chown -R apache:apache /var/www/

# Test Apache configuration
sudo httpd -t

# Restart Apache to load virtual hosts
sudo systemctl restart httpd

echo "✅ Virtual hosts configured successfully!"
