Prerequisites#

Before starting, ensure you have:

An Ubuntu 24.04 LTS server (physical, virtual, or cloud-based, e.g., AWS EC2, DigitalOcean Droplet).
A user account with sudo privileges (to run administrative commands).
A stable internet connection (to download packages).
(Optional) A domain name pointing to your server’s IP (for production; skip for local testing).

Setting Up the LAMP Stack#

A LAMP stack is the foundation for hosting WordPress. Let’s install each component step-by-step.

Step 1: Install Apache Web Server#

Apache is a popular open-source web server that handles HTTP requests and serves web content.

Update your system packages (always a good first step to ensure you have the latest software):
```
sudo apt update && sudo apt upgrade -y  
```
Install Apache:
```
sudo apt install apache2 -y  
```
Verify Apache is running:
```
sudo systemctl status apache2  
```
You should see active (running) in the output.
Enable Apache to start on boot:
```
sudo systemctl enable apache2  
```
Configure the firewall (if using ufw, Ubuntu’s default firewall) to allow HTTP (port 80) and HTTPS (port 443) traffic:
```
sudo ufw allow 'Apache Full'  
```
Verify the rule with:
```
sudo ufw status  
```
Test Apache: Open a browser and navigate to your server’s public IP (e.g., http://your-server-ip). You’ll see Apache’s default Ubuntu page, confirming Apache is working.

Step 2: Install MySQL Database Server#

MySQL is a relational database management system (RDBMS) that stores WordPress data (posts, users, settings).

Install MySQL Server:
```
sudo apt install mysql-server -y  
```
Verify MySQL is running:
```
sudo systemctl status mysql  
```
Output should show active (running).
Secure the MySQL installation (critical for security):
Run the built-in security script to set a root password, remove anonymous users, and disable remote root login:
```
sudo mysql_secure_installation  
```
Follow the prompts:
- Press Y to enable the Validate Password Plugin (recommended).
- Set a strong root password (store this securely!).
- Answer Y to all remaining questions (remove anonymous users, disallow remote root login, remove test database, reload privileges).
Test MySQL access: Log into the MySQL shell as the root user:
```
sudo mysql -u root -p  
```
Enter the root password you set earlier. You’ll see the MySQL prompt (mysql>), confirming access. Exit with:
```
exit;  
```

Step 3: Install PHP and Required Extensions#

PHP is a server-side scripting language that processes dynamic content (e.g., WordPress themes/plugins). WordPress requires PHP 7.4 or higher; Ubuntu 24.04 includes PHP 8.3 by default (fully compatible).

Install PHP and essential modules (including MySQL support and WordPress dependencies):
```
sudo apt install php libapache2-mod-php php-mysql php-curl php-gd php-mbstring php-xml php-xmlrpc php-soap php-intl php-zip -y  
```
- libapache2-mod-php: Connects Apache to PHP.
- php-mysql: Allows PHP to communicate with MySQL.
- Other modules: Required for WordPress features (e.g., image uploads, XML-RPC, internationalization).
Verify PHP installation:
Create a test PHP file in Apache’s web root (/var/www/html):
```
sudo nano /var/www/html/info.php  
```
Add this code:
```
<?php phpinfo(); ?>  
```
Save and exit (Ctrl+O, Enter, Ctrl+X).
Test PHP: In a browser, visit http://your-server-ip/info.php. You’ll see a PHP info page with details about your PHP configuration.
Note: Delete info.php after testing (it exposes sensitive server info):
```
sudo rm /var/www/html/info.php  
```
Restart Apache to apply PHP changes:
```
sudo systemctl restart apache2  
```

Creating a MySQL Database and User for WordPress#

WordPress needs a dedicated database and user to store its data. Using the root MySQL user is insecure, so we’ll create a limited-privilege user.

Log into MySQL as root:
```
sudo mysql -u root -p  
```
Create a WordPress database (replace wordpress_db with your preferred name):
```
CREATE DATABASE wordpress_db DEFAULT CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci;  
```
- utf8mb4 supports all Unicode characters, including emojis.

Create a MySQL user (replace wp_user and strong_password with your own):

CREATE USER 'wp_user'@'localhost' IDENTIFIED BY 'strong_password';

Grant privileges to the user on the WordPress database:

GRANT ALL PRIVILEGES ON wordpress_db.* TO 'wp_user'@'localhost';

Flush privileges to apply changes:
```
FLUSH PRIVILEGES;  
```
Exit MySQL:
```
exit;  
```
