To install Nginx, MySQL, and PHP on Ubuntu, follow these steps:

1. Update the package manager’s package list:

sudo apt update

2. Install Nginx:

sudo apt install nginx

3. Install MySQL:

sudo apt install mysql-server

During the installation process, you will be prompted to set a password for the MySQL root user. Make sure to choose a strong password and remember it, as you will need it later.

4. Install PHP and the PHP MySQL extension:

sudo apt install php-fpm php-mysql

5. Configure Nginx to use PHP by modifying the Nginx configuration file.

Open the Nginx configuration file in a text editor:

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

Find the lines that specify the location of the PHP handler:

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

These lines tell Nginx to pass PHP requests to the PHP processor (PHP-FPM) through a Unix socket. Make sure that the PHP version in the fastcgi_pass line (e.g. php7.4) matches the version of PHP you installed.

6. Restart Nginx to apply the changes:

sudo systemctl restart nginx

Now, Nginx, MySQL, and PHP should be installed and configured on your Ubuntu system. To test that everything is working correctly, you can create a simple PHP script and access it through a web browser.

Create a PHP file in the Nginx web root directory:

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

Paste the following PHP code into the file:

<?php
phpinfo();

Save the file and exit the text editor.

In a web browser, access the PHP file by going to http://your_server_ip/info.php. You should see a page with information about your PHP installation.

Note: These instructions are for Ubuntu 20.04. The exact steps may vary slightly depending on your version of Ubuntu and the software versions you are installing.
