Install WordPress with Nginx on Ubuntu: A Detailed Guide

In the ever-evolving world of web development, choosing the right technology stack is crucial for building a robust and scalable website. WordPress, a popular content management system (CMS), empowers users with unparalleled flexibility and ease of use. Nginx, a high-performance web server, is known for its efficiency and resource-friendliness. Combining these two powerhouse tools on the stable and user-friendly Ubuntu operating system provides a potent foundation for any web project.

This comprehensive guide will walk you through the steps of installing WordPress with Nginx on Ubuntu, ensuring a seamless and secure setup. We'll cover everything from installing the necessary software to configuring the server and securing your WordPress installation.

Step 1: Setting the Stage – Ubuntu Installation and Updates

First things first, we need a clean and updated Ubuntu server to work with. If you don't already have one, follow these steps:

Download Ubuntu Server: Head over to the official Ubuntu website and download the latest LTS (Long-Term Support) version of Ubuntu Server. Choose the appropriate .iso image based on your system architecture (32-bit or 64-bit).
Create a Bootable Media: Use a tool like Rufus or Etcher to create a bootable USB drive or DVD from the downloaded .iso file.
Boot from the Bootable Media: Boot your server from the USB drive or DVD.
Install Ubuntu Server: Follow the on-screen instructions to install Ubuntu Server. You'll be prompted to choose a language, configure the keyboard layout, and set up a user account.
Update and Upgrade: Once Ubuntu Server is installed, log in as the administrator and update the system:
```
sudo apt update
sudo apt upgrade
```

Step 2: Configuring the Nginx Web Server

Now that we have Ubuntu ready, it's time to install and configure Nginx.

Install Nginx: Use the following command to install Nginx from the official Ubuntu repositories:
```
sudo apt install nginx
```
Start and Enable Nginx: After installation, start Nginx and enable it to automatically start on system boot:
```
sudo systemctl start nginx
sudo systemctl enable nginx
```
Verify Nginx Installation: Open a web browser and navigate to http://your_server_ip. If you see the Nginx welcome page, congratulations! You have successfully installed Nginx.

Step 3: Preparing the Database for WordPress

WordPress relies on a database to store all its content, including posts, pages, comments, and user information. We'll use MySQL, a popular and robust database management system, for this purpose.

Install MySQL: Use the following command to install MySQL:
```
sudo apt install mysql-server
```
Secure MySQL: After installation, run the mysql_secure_installation script to secure your MySQL installation:
```
sudo mysql_secure_installation
```
Follow the on-screen instructions to set a strong password for the root user, remove anonymous users, and restrict remote root logins.
Create a Database and User: Log in to the MySQL shell using the root user:
```
mysql -u root -p
```
Enter the password you set during the security setup. Now, create a new database for your WordPress installation:
```
CREATE DATABASE wordpress;
```
Create a new user with appropriate privileges for the database:
```
CREATE USER 'wordpress_user'@'localhost' IDENTIFIED BY 'your_password';
```
Grant all privileges to the user on the WordPress database:
```
GRANT ALL PRIVILEGES ON wordpress.* TO 'wordpress_user'@'localhost';
```
Flush the privileges to apply the changes:
```
FLUSH PRIVILEGES;
```
Exit the MySQL shell:
```
exit;
```

Step 4: Downloading and Installing WordPress

Now that we have Nginx and MySQL ready, it's time to download and install WordPress.

Download WordPress: Go to the official WordPress website and download the latest version of WordPress. Save the downloaded ZIP file to your server.
Extract the WordPress Files: Use the following command to extract the WordPress files to the /var/www/html directory (the default web root directory for Nginx):
```
sudo unzip wordpress-*.zip -d /var/www/html
```
Configure File Permissions: Adjust file permissions for the WordPress directory and its contents to ensure proper ownership and access:
```
sudo chown -R www-data:www-data /var/www/html
sudo chmod -R 755 /var/www/html
```
Create a WordPress Configuration File: Navigate to the WordPress directory and create a new configuration file:
```
cd /var/www/html/wordpress
sudo cp wp-config-sample.php wp-config.php
```
Open the wp-config.php file in a text editor and modify the following settings:
- Database Name: Replace database_name with the name of the database you created earlier.
- Database Username: Replace username with the database username.
- Database Password: Replace password with the database password.
- Database Host: Leave this as localhost unless you're using a remote database.
- Table Prefix: This value defines the prefix for all WordPress tables in your database. You can leave it as the default or change it to something unique.

Step 5: Configuring Nginx for WordPress

The final step is to configure Nginx to serve your WordPress site.

Create a Server Block: Create a new Nginx server block file for your WordPress site. We'll create it in the /etc/nginx/sites-available directory.

sudo nano /etc/nginx/sites-available/wordpress

Paste the following configuration inside the file:

server {
    listen 80;
    server_name your_domain.com www.your_domain.com;

    root /var/www/html/wordpress;
    index index.php index.html index.htm;

    location / {
        try_files $uri $uri/ /index.php?$args;
    }

    location ~ \.php$ {
        include snippets/fastcgi-php.conf;
        fastcgi_pass unix:/run/php/php7.4-fpm.sock;
        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
        include fastcgi_params;
    }
}

Replace your_domain.com with your actual domain name. If you don't have a domain yet, you can use your server's IP address instead.

Enable the Server Block: Create a symbolic link to the server block file in the /etc/nginx/sites-enabled directory:
```
sudo ln -s /etc/nginx/sites-available/wordpress /etc/nginx/sites-enabled/wordpress
```
Test and Reload Nginx: Test the Nginx configuration for errors and reload the Nginx service:
```
sudo nginx -t
sudo systemctl reload nginx
```

Step 6: Completing the WordPress Installation

Now, open a web browser and navigate to http://your_domain.com. You should see the WordPress installation screen.

Enter Database Information: Enter the database name, username, password, and host you set up earlier.
Choose Site Title and Admin Details: Enter your desired site title, username, password, and email address for the administrator account.
Install WordPress: Click the "Install WordPress" button to complete the installation.
