In today's digital landscape, efficiently deploying robust web applications is essential for developers and businesses. Laravel has become one of the most elegant PHP frameworks, offering a streamlined development experience. However, successful deployment requires careful configuration of various components to ensure optimal performance, security, and reliability.

This guide provides a comprehensive walkthrough for deploying a Laravel application on an Ubuntu server, covering everything from basic server setup to advanced configurations such as reverse proxies and automated deployments.

Prerequisites

• An Ubuntu server (preferably Ubuntu 22.04 LTS or newer)

• SSH access with sudo privileges

• A domain name pointing to your server (optional but recommended)

• Basic knowledge of Linux commands

Step 1: Install and Configure Nginx

Nginx is a high-performance web server that will serve your Laravel application to users.

sudo apt update
sudo apt install -y nginx
sudo systemctl start nginx
sudo systemctl enable nginx

Step 2: Install PHP 8.3 and Required Extensions

Laravel requires PHP and several PHP extensions to function properly. PHP 8.3 offers significant performance improvements over older versions.

sudo apt install -y php8.3 \
  php8.3-common \
  php8.3-opcache \
  php8.3-cli \
  php8.3-gd \
  php8.3-curl \
  php8.3-mysql \
  php8.3-mbstring \
  php8.3-zip \
  php8.3-xml \
  php8.3-intl \
  php8.3-bcmath \
  php8.3-soap \
  php8.3-fpm \
  php8.3-imagick \
  php8.3-ldap

Verify your PHP installation with:

php -v

Step 3: Set Up MySQL Database

sudo apt install -y mysql-server
sudo systemctl start mysql
sudo systemctl enable mysql

Step 4: Create Database and User

sudo mysql -u root

CREATE USER 'admin'@'localhost' IDENTIFIED BY 'yourpassword';
GRANT ALL PRIVILEGES ON *.* TO 'admin'@'localhost' WITH GRANT OPTION;
FLUSH PRIVILEGES;
CREATE DATABASE `tech_adda`;
EXIT;

Note: Remember to replace 'yourpassword' with a strong, unique password in a production environment.
Step 5: Install Supervisor for Queue Management

Step 5: Install Supervisor for Queue Management

sudo apt-get install -y supervisor
sudo systemctl start supervisor
sudo systemctl enable supervisor

Step 6: Install Git for Version Control

sudo apt-get install -y git

sudo mkdir -p /var/www/tech_adda
sudo chown -R www-data:www-data /var/www/tech_adda

Step 8: Clone Your Repository

For private repositories, you'll need to set up SSH keys:

# Generate SSH key
ssh-keygen -t rsa -b 4096 -C "your-email@example.com"

# Display the public key to add to GitHub/GitLab
cat ~/.ssh/id_rsa.pub

Then clone your repository:

cd /var/www
sudo git clone https://github.com/yourusername/your-repo.git tech_adda
sudo chown -R www-data:www-data /var/www/tech_adda

Step 9: Configure Nginx for Your Laravel Application

Create a new server block configuration:

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

Add the following configuration:

server {
    listen 80;
    listen [::]:80;
    server_name your-domain.com;  # Replace with your domain
    root /var/www/tech_adda/public;

    add_header X-Frame-Options "SAMEORIGIN";
    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/php8.3-fpm.sock;
        fastcgi_param SCRIPT_FILENAME $realpath_root$fastcgi_script_name;
        include fastcgi_params;
        fastcgi_hide_header X-Powered-By;
    }

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

Enable the site and test your configuration:

sudo ln -s /etc/nginx/sites-available/tech_adda /etc/nginx/sites-enabled/
sudo rm -f /etc/nginx/sites-enabled/default  # Remove default site if needed
sudo nginx -t
sudo systemctl restart nginx

Step 10: Set Up Supervisor for Laravel Queue Workers

Create a Supervisor configuration file:

sudo nano /etc/supervisor/conf.d/tech_adda.conf

Add this configuration:

[program:tech_adda-worker]
process_name=%(program_name)s_%(process_num)02d
command=php /var/www/tech_adda/artisan queue:work --sleep=3 --tries=3
autostart=true
autorestart=true
user=www-data
numprocs=2
redirect_stderr=true
stdout_logfile=/var/www/tech_adda/storage/logs/worker.log
stopwaitsecs=3600

Update Supervisor:

sudo supervisorctl reread
sudo supervisorctl update
sudo supervisorctl start tech_adda-worker:*

Step 11: Configure Laravel Environment

cd /var/www/tech_adda
sudo cp .env.example .env
sudo php artisan key:generate
sudo php artisan config:cache
sudo php artisan route:cache

Install dependencies:

# For Composer dependencies
sudo composer install --no-dev --optimize-autoloader

# For frontend assets
sudo npm install
sudo npm run production

Set Proper File Permissions

Laravel requires specific permissions to function correctly. The web server needs to be able to write to certain directories:

 cd /var/www/tech_adda
 # Set the web server as the owner
 sudo chown -R www-data:www-data .
 # Add your user to group
 sudo usermod -a -G www-data user
 # Set file(s) permission
 sudo find . -type f -exec chmod 644 {} \;
 # Set folder(s) permission
 sudo find . -type d -exec chmod 755 {} \;
 # Set cache directory permission
 sudo chgrp -R www-data storage bootstrap/cache
 sudo chmod -R ug+rwx storage bootstrap/cache

These commands ensure that:

• All files have 644 permissions (owner can read/write, group and others can read)

• All directories have 755 permissions (owner can read/write/execute, group and others can read/execute)

• Storage and cache directories have 775 permissions (owner and group can read/write/execute, others can read/execute)

Note: Incorrect permissions are a common source of issues in Laravel applications, particularly for caching, session handling, and file uploads.

Step 12: Automated Deployments (Optional)

Create a deployment script for easier updates:

sudo nano /var/www/deploy.sh

Add this script:

#!/bin/bash
cd /var/www/tech_adda
git pull origin main
composer install --no-dev --optimize-autoloader
php artisan migrate --force
php artisan config:cache
php artisan route:cache
php artisan view:cache
sudo supervisorctl restart tech_adda-worker:*
sudo systemctl restart php8.3-fpm

Make the script executable:

sudo chmod +x /var/www/deploy.sh

Step 14: Secure Your Installation

Install Certbot for SSL certificates:

sudo apt install -y certbot python3-certbot-nginx
sudo certbot --nginx -d your-domain.com
sudo certbot --nginx -d proxy.your-domain.com  # For your reverse proxy

Set up a basic firewall:

sudo apt install -y ufw
sudo ufw allow 'Nginx Full'
sudo ufw allow ssh
sudo ufw enable

Conclusion

You now have a fully configured Laravel application running on Ubuntu with Nginx, PHP 8.3, MySQL, and all the necessary components for a production environment. This setup provides:

• High-performance web serving with Nginx

• Latest PHP version with optimized extensions

• Reliable database with MySQL

• Background job processing with Supervisor

• Version control with Git

• Optional reverse proxy capabilities

• HTTPS security with Let's Encrypt

• Basic firewall protection

Remember to regularly update your server's packages and your Laravel application to maintain security and performance. With this foundation in place, your Laravel application is ready to serve users efficiently and securely.
