Step 1 – Installing the Nginx Web Server

sudo apt update
sudo apt install nginx

If you have the ufw firewall enabled, as recommended in our initial server setup guide, you will need to allow connections to Nginx.

sudo ufw app list
Output
Available applications:
  Nginx Full
  Nginx HTTP
  Nginx HTTPS
  OpenSSH

Since you haven’t configured SSL for your server in this guide, you will only need to allow regular HTTP traffic on port 80

sudo ufw allow 'Nginx HTTP'

Step 2 — Installing MySQL

sudo apt install mysql-server
sudo mysql_secure_installation

Step 3 – Installing PHP

sudo apt install php-fpm php-mysql

Step 4 — Configuring Nginx to Use the PHP Processor

sudo mkdir /var/www/your_domain
sudo chown -R $USER:$USER /var/www/your_domain
sudo nano /etc/nginx/sites-available/your_domain

This will create a new blank file. Paste in the following bare-bones configuration:

server {
    listen 80;
    server_name your_domain www.your_domain;
    root /var/www/your_domain;

    index index.html index.htm index.php;

    location / {
        try_files $uri $uri/ =404;
    }

    location ~ \.php$ {
        include snippets/fastcgi-php.conf;
        fastcgi_pass unix:/var/run/php/php7.4-fpm.sock;
     }

    location ~ /\.ht {
        deny all;
    }

}

Activate your configuration by linking to the config file from Nginx’s sites-enabled directory:

sudo ln -s /etc/nginx/sites-available/your_domain /etc/nginx/sites-enabled/your_domain
sudo unlink /etc/nginx/sites-enabled/default
sudo nginx -t
sudo systemctl reload nginx
