The sudo apt update command refreshes the package list, while sudo apt upgrade upgrades the installed packages to their latest versions. This process might take a few minutes, depending on your internet connection and system configuration. These commands are essential for ensuring your system is running smoothly before installing new softwar.

Step 2: Install Apache Web Server

Apache is a widely-used web server that will host your WordPress site. It’s responsible for serving your website files to visitors. Installing Apache is straightforward and essential for running WordPress.

Use the following command to install Apache:

sudo apt install apache2

Once the installation is complete, start the Apache service with:

sudo systemctl start apache2

To ensure Apache starts automatically on boot, enable it with:

sudo systemctl enable apache2

Verify the installation by opening a web browser and navigating to http://localhost/. You should see the default Apache welcome page, confirming that Apache is running correctly. If you encounter any issues, double-check the commands and ensure your system is connected to the internet. This verification step ensures that the web server is properly installed and accessible.

Step 3: Install MySQL/MariaDB Database Server

WordPress requires a database to store its data, including posts, pages, and settings. MySQL and MariaDB are popular database management systems that work well with WordPress. This guide uses MariaDB due to its open-source nature and compatibility.

Install MariaDB with the following command:

sudo apt install mariadb-server mariadb-client

After installation, start the MariaDB service:

sudo systemctl start mariadb

Enable MariaDB to start on boot:

sudo systemctl enable mariadb

Secure your MariaDB installation by running:

sudo mysql_secure_installation

This command will guide you through setting up a root password and other security options. It’s crucial to set a strong root password and answer the security questions carefully to protect your database. Securing your database is a critical step in protecting your WordPress site.

Step 4: Install PHP and Required Extensions

WordPress is written in PHP, so you’ll need to install PHP along with several extensions for WordPress to function correctly. These extensions provide additional functionalities and ensure compatibility.

Install PHP and the necessary extensions with:

sudo apt install php libapache2-mod-php php-mysql php-gd php-curl php-mbstring php-xml php-imagick

Once installed, restart the Apache service to enable the new PHP modules:

sudo systemctl restart apache2

Verify the PHP installation by creating a phpinfo file in the web server’s document root. Create a file named info.php:

sudo nano /var/www/html/info.php

Add the following content:

<?php
 phpinfo();
 ?>

Save the file and access it via your web browser by navigating to http://localhost/info.php. You should see a page displaying your PHP configuration information. Remember to delete this file after verification, as it can pose a security risk if left exposed. This ensures that PHP is correctly installed and configured for WordPress.

Step 5: Download and Extract WordPress

Now, download the latest version of WordPress from the official website and extract it to the web server’s document root. This involves navigating to the temporary directory, downloading the WordPress archive, and extracting its contents.

Navigate to the /tmp directory:

cd /tmp

Download the latest WordPress package using wget:

sudo wget https://wordpress.org/latest.tar.gz

Extract the downloaded archive:

sudo tar -xvzf latest.tar.gz

Move the WordPress files to the web server document root:

sudo mv wordpress/* /var/www/html/

This ensures that all WordPress files are correctly placed in the directory that Apache serves.

Step 6: Configure WordPress Directory Permissions

Setting the correct file permissions is crucial for WordPress to function securely. Incorrect permissions can lead to security vulnerabilities or prevent WordPress from writing to necessary files.

Set the ownership of the WordPress files to the Apache user (www-data):

sudo chown -R www-data:www-data /var/www/html/

Set appropriate permissions:

sudo chmod -R 755 /var/www/html/

These commands ensure that Apache has the necessary permissions to read and write files within the WordPress directory.

Step 7: Create a MySQL/MariaDB Database and User for WordPress

WordPress needs a database to store its data. Create a database and a user account with the necessary privileges to access and modify the database. This ensures that WordPress can properly manage its data.

Log in to the MariaDB shell as the root user:

sudo mysql -u root -p

Enter the root password you set during the MariaDB installation. Then, execute the following SQL commands:

CREATE DATABASE wordpress;
CREATE USER 'wordpressuser'@'localhost' IDENTIFIED BY 'password';
GRANT ALL PRIVILEGES ON wordpress.* TO 'wordpressuser'@'localhost';
FLUSH PRIVILEGES;
exit

Replace 'password' with a strong, unique password. These commands create a database named wordpress, a user named wordpressuser, and grant the user full access to the database.

Step 8: Configure WordPress wp-config.php File

The wp-config.php file contains essential configuration settings for WordPress, including database connection details. Configuring this file correctly is crucial for WordPress to connect to the database.

Navigate to the WordPress directory:

cd /var/www/html/

Copy the sample configuration file:

sudo cp wp-config-sample.php wp-config.php

Open the wp-config.php file in a text editor:

sudo nano wp-config.php

Modify the following lines with your database details:

define( 'DB_NAME', 'wordpress' );
define( 'DB_USER', 'wordpressuser' );
define( 'DB_PASSWORD', 'password' );
define( 'DB_HOST', 'localhost' );

Replace 'wordpress', 'wordpressuser', and 'password' with the database name, username, and password you created in the previous step. Also, update the security keys and salts. You can generate unique keys from the WordPress API:

define('AUTH_KEY',         'put your unique phrase here');
 define('SECURE_AUTH_KEY',  'put your unique phrase here');
 define('LOGGED_IN_KEY',    'put your unique phrase here');
 define('NONCE_KEY',        'put your unique phrase here');
 define('AUTH_SALT',        'put your unique phrase here');
 define('SECURE_AUTH_SALT', 'put your unique phrase here');
 define('LOGGED_IN_SALT',   'put your unique phrase here');
 define('NONCE_SALT',       'put your unique phrase here');

Save the file. This configuration ensures that WordPress can connect to the database and retrieve necessary information.

Step 9: Configure Apache Virtual Host for WordPress

Creating an Apache virtual host allows you to host multiple websites on a single server. This step involves creating a new configuration file for your WordPress site and enabling it.

Create a new Apache configuration file for WordPress:

sudo nano /etc/apache2/sites-available/wordpress.conf

Add the virtual host configuration:

<VirtualHost *:80>
  ServerAdmin admin@example.com
  DocumentRoot /var/www/html/
  ServerName example.com
  ServerAlias www.example.com
 

  <Directory /var/www/html/>
  AllowOverride All
  Require all granted
  </Directory>
 

  ErrorLog ${APACHE_LOG_DIR}/error.log
  CustomLog ${APACHE_LOG_DIR}/access.log combined
 </VirtualHost>

Replace example.com with your domain name. Save the file and enable the new virtual host:

sudo a2ensite wordpress.conf

Disable the default Apache site:

sudo a2dissite 000-default.conf

Test the Apache configuration:

sudo apachectl configtest

Restart the Apache service:

sudo systemctl restart apache2

This configuration ensures that your WordPress site is correctly configured within Apache.

Step 10: Access the WordPress Installation Wizard

Now that you’ve configured the server and files, you can access the WordPress installation wizard through your web browser. This final step involves setting up your site title, admin credentials, and email address.

Open a web browser and navigate to your server’s IP address or domain name. Follow the on-screen instructions to complete the WordPress installation:
