# Nginx Web Server

If Nginx is not already installed on your server, you can install it using the appropriate command for your operating system. For example, on Ubuntu, you can use:

sudo apt-get install nginx

Virtual Host Configuration: Create a virtual host configuration file for the Link Shortener application.

1. Open a text editor to create a new virtual host file. For instance, create a file named link-shortener in the /etc/nginx/sites-available/ directory:

sudo nano /etc/nginx/sites-available/link-shortener

2. Add the following configuration (replace example.com with your own domain name or IP address, and replace link-shortener with the actual path to your Link Shortener application directory):

server {
    listen 80;
    server_name example.com;

    root /var/www/html/link-shortener;
    index index.php;

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

    location ~ \.php$ {
        include fastcgi_params;
        fastcgi_pass unix:/run/php/php7.4-fpm.sock; # Set the appropriate PHP version
        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
    }

    access_log /var/log/nginx/link-shortener-access.log;
    error_log /var/log/nginx/link-shortener-error.log;
}

3. Save the file and close the text editor.

Create a symbolic link to enable the virtual host:

sudo ln -s /etc/nginx/sites-available/link-shortener /etc/nginx/sites-enabled/

To apply the Nginx configuration changes, restart the Nginx web server:

sudo service nginx restart

Now, upload the Link Shortener application files to the document root configured in the Nginx virtual host. In the example above, it's /var/www/html/link-shortener.

Open your web browser and visit the domain or IP address you configured in the Nginx virtual host (e.g., http://example.com). You should see the homepage of your Link Shortener application.
