sudo nano /etc/php/8.2/fpm/php.ini

# Set these values:
# memory_limit = 256M
# upload_max_filesize = 64M
# post_max_size = 64M
# max_execution_time = 300

# Restart PHP-FPM
sudo systemctl restart php8.2-fpm
sudo systemctl enable php8.2-fpm
```

## Application Deployment

### 1. Create Application Directory
```bash
sudo mkdir -p /var/www/bikeservice
sudo chown -R $USER:$USER /var/www/bikeservice
cd /var/www/bikeservice
```

### 2. Clone Your Repository
```bash
git clone <your-repository-url> .
# Or upload your files via SCP/SFTP
```

### 3. Backend Setup (Laravel)
```bash
cd backend

# Install dependencies
composer install --no-dev --optimize-autoloader

# Set permissions
sudo chown -R www-data:www-data storage bootstrap/cache
sudo chmod -R 775 storage bootstrap/cache

# Create .env file
cp .env.example .env

# Generate application key
php artisan key:generate

# Configure database (update .env file)
# For production, consider using MySQL/PostgreSQL instead of SQLite

# Run migrations
php artisan migrate --force

# Clear and cache config
php artisan config:cache
php artisan route:cache
php artisan view:cache

# Set production environment
echo "APP_ENV=production" >> .env
echo "APP_DEBUG=false" >> .env
```

### 4. Frontend Setup (Vue.js)
```bash
cd ../frontend

# Install dependencies
npm install

# Build for production
npm run build

# Copy built files to Laravel public directory
cp -r dist/* ../backend/public/
```

## Nginx Configuration

### 1. Create Nginx Site Configuration
```bash
sudo nano /etc/nginx/sites-available/bikeservice
```

Add this configuration:
```nginx
server {
    listen 80;
    server_name your-domain.com www.your-domain.com;
    root /var/www/bikeservice/backend/public;
    index index.php index.html index.htm;

    # Security headers
    add_header X-Frame-Options "SAMEORIGIN" always;
    add_header X-XSS-Protection "1; mode=block" always;
    add_header X-Content-Type-Options "nosniff" always;
    add_header Referrer-Policy "no-referrer-when-downgrade" always;
    add_header Content-Security-Policy "default-src 'self' http: https: data: blob: 'unsafe-inline'" always;

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

    location ~ \.php$ {
        fastcgi_pass unix:/var/run/php/php8.2-fpm.sock;
        fastcgi_index index.php;
        fastcgi_param SCRIPT_FILENAME $realpath_root$fastcgi_script_name;
        include fastcgi_params;
    }

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

    # Cache static assets
    location ~* \.(js|css|png|jpg|jpeg|gif|ico|svg)$ {
        expires 1y;
        add_header Cache-Control "public, immutable";
    }
}
```

### 2. Enable Site and Restart Nginx
```bash
sudo ln -s /etc/nginx/sites-available/bikeservice /etc/nginx/sites-enabled/
sudo nginx -t
sudo systemctl restart nginx
sudo systemctl enable nginx
```

## SSL Certificate (Optional but Recommended)

### 1. Install Certbot
```bash
sudo apt install certbot python3-certbot-nginx -y
```

### 2. Obtain SSL Certificate
```bash
sudo certbot --nginx -d your-domain.com -d www.your-domain.com
```

## Final Configuration

### 1. Set Proper Permissions
```bash
sudo chown -R www-data:www-data /var/www/bikeservice
sudo chmod -R 755 /var/www/bikeservice
sudo chmod -R 775 /var/www/bikeservice/backend/storage
sudo chmod -R 775 /var/www/bikeservice/backend/bootstrap/cache
```

### 2. Configure Queue Worker (if using queues)
```bash
# Create systemd service for queue worker
sudo nano /etc/systemd/system/bikeservice-queue.service
```

Add this content:
```ini
[Unit]
Description=Bike Service Queue Worker
After=network.target

[Service]
Type=simple
User=www-data
Group=www-data
WorkingDirectory=/var/www/bikeservice/backend
ExecStart=/usr/bin/php artisan queue:work --sleep=3 --tries=3 --max-time=3600
Restart=always
RestartSec=10

[Install]
WantedBy=multi-user.target
```

Enable and start the service:
```bash
sudo systemctl enable bikeservice-queue
sudo systemctl start bikeservice-queue
```

### 3. Set up Cron for Laravel Scheduler
```bash
crontab -e
```

Add this line:
```
* * * * * cd /var/www/bikeservice/backend && php artisan schedule:run >> /dev/null 2>&1
```

## Deployment Script

Create a deployment script for future updates:
```bash
#!/bin/bash
# deploy.sh

cd /var/www/bikeservice

# Pull latest changes
git pull origin main

# Backend deployment
cd backend
composer install --no-dev --optimize-autoloader
php artisan config:cache
php artisan route:cache
php artisan view:cache

# Frontend deployment
cd ../frontend
npm install
npm run build
cp -r dist/* ../backend/public/

# Set permissions
sudo chown -R www-data:www-data /var/www/bikeservice
sudo chmod -R 755 /var/www/bikeservice
sudo chmod -R 775 /var/www/bikeservice/backend/storage
sudo chmod -R 775 /var/www/bikeservice/backend/bootstrap/cache

# Restart services
sudo systemctl restart php8.2-fpm
sudo systemctl restart nginx

echo "Deployment completed!"
```

Make it executable:
```bash
chmod +x deploy.sh
```

## Monitoring and Maintenance

### 1. Check Application Status
```bash
# Check Nginx status
sudo systemctl status nginx

# Check PHP-FPM status
sudo systemctl status php8.2-fpm

# Check queue worker status
sudo systemctl status bikeservice-queue

# Check Laravel logs
tail -f /var/www/bikeservice/backend/storage/logs/laravel.log
```

### 2. Regular Maintenance
```bash
# Update system packages
sudo apt update && sudo apt upgrade -y

# Clear Laravel caches
cd /var/www/bikeservice/backend
php artisan cache:clear
php artisan config:clear
php artisan route:clear
php artisan view:clear

# Rebuild caches
php artisan config:cache
php artisan route:cache
php artisan view:cache
```

## Troubleshooting

### Common Issues:
1. **Permission denied errors**: Check file ownership and permissions
2. **500 Internal Server Error**: Check Laravel logs and PHP-FPM logs
3. **Database connection issues**: Verify database configuration in .env
4. **Static assets not loading**: Check Nginx configuration and file paths

### Useful Commands:
```bash
# Check Nginx error logs
sudo tail -f /var/log/nginx/error.log

# Check PHP-FPM logs
sudo tail -f /var/log/php8.2-fpm.log

# Test Nginx configuration
sudo nginx -t

# Restart all services
sudo systemctl restart nginx php8.2-fpm bikeservice-queue
```

## Security Considerations

1. **Firewall**: Configure UFW firewall
2. **SSH**: Use key-based authentication and change default port
3. **Database**: Use strong passwords and limit access
4. **Updates**: Keep system and packages updated
5. **Backups**: Set up regular backups of your application and database

## Performance Optimization

1. **OPcache**: Enable PHP OPcache for better performance
2. **Redis**: Consider using Redis for caching and sessions
3. **CDN**: Use a CDN for static assets
4. **Database**: Optimize database queries and indexes
5. **Monitoring**: Set up application monitoring (Laravel Telescope, etc.)
