Install MariaDB.

$ sudo apt install -y mariadb-client mariadb-server
Start MariaDB.

$ sudo systemctl enable --now mariadb.service
The root password is blank for a newly installed MariaDB server. Configure the MariaDB security by answering these questions appropriately for your server.

$ sudo mysql_secure_installation
2. Install Laravel
Replace example with your project name where it appears throughout this guide.

Create a Laravel project with Composer. You may disregard the warning not to run Composer as root for this step. See the Composer documentation for details.

$ cd /var/www/html
$ sudo composer global require laravel/installer
$ sudo composer create-project --prefer-dist laravel/laravel example
Grant your non-root user access.

$ sudo chmod -R 755 /var/www/html/example
$ sudo chown -R example_user:example_user /var/www/html/example
Install the example project.

$ cd example
$ composer install
Test the Laravel application manually in the /var/www/html/example folder. Replace the example IP address with your server's IP.

$ cd /var/www/html/example
$ php artisan serve --host=192.0.2.123 --port=8000
To access this example:

http://192.0.2.123:8000
Type CTRL+C in your SSH session to stop the Laravel application.

3. Configure Nginx
For public/production use, configure Nginx.

Set the file permissions. Replace example with your Laravel project name.

$ sudo chmod -R 755 /var/www/html/example
$ sudo chown -R www-data:www-data /var/www/html/example
Create an Nginx configuration file.

$ sudo nano /etc/nginx/sites-available/example
Paste the following to your example configuration file.

Replace server_name example.com; with your domain or server IP address. You can also use an underscore as a wildcard, for example: server_name _;
Replace /var/www/html/example/public with your project path.
If you installed a different version of PHP, edit the /var/run/php/php7.4-fpm.sock value for your version. You can find your sock file in /var/run/php/.

server {
    listen 80;
    server_name example.com;
    root /var/www/html/example/public;

    add_header X-Frame-Options "SAMEORIGIN";
    add_header X-XSS-Protection "1; mode=block";
    add_header X-Content-Type-Options "nosniff";

    index index.php;

    charset utf-8;

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

    location = /favicon.ico { access_log off; log_not_found off; }
    location = /robots.txt  { access_log off; log_not_found off; }

    error_page 404 /index.php;

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

    location ~ /\.(?!well-known).* {
        deny all;
    }
}
Enable the Nginx configuration.

$ sudo ln -s /etc/nginx/sites-available/example /etc/nginx/sites-enabled/
Remove the default configuration file.

$ sudo rm /etc/nginx/sites-enabled/default
Restart Nginx.

$ sudo systemctl restart nginx
Test that your Laravel application loads properly in a web browser.

http://example.com/
4. Configure MariaDB
Log in to MariaDB as root.

# mysql -p -u root
Create a database named laravelexample.

MariaDB [(none)]> CREATE DATABASE `laravelexample` CHARACTER SET utf8 COLLATE utf8_general_ci;
Create a database user.

MariaDB [(none)]> CREATE USER 'laravelexampleuser'@'%' IDENTIFIED BY 'password';
Grant permissions.

MariaDB [(none)]> use laravelexample;
MariaDB [laravelexample]> GRANT ALL ON `laravelexample.*` TO 'laravelexampleuser'@'%';
MariaDB [laravelexample]> FLUSH PRIVILEGES;
MariaDB [laravelexample]> EXIT;
Edit the Laravel application .env file.

$ sudo nano /var/www/html/example/.env
Set the database connection variables.

DB_CONNECTION=mysql
DB_HOST=127.0.0.1
DB_PORT=3306
DB_DATABASE=laravelexample
DB_USERNAME=laravelexampleuser
DB_PASSWORD=password
Save and exit the file.
