# Redirect HTTP to HTTPS
server {
    listen 80;
    server_name example.com www.example.com;
    return 301 https://$server_name$request_uri;
}

# HTTPS server
server {
    listen 443 ssl http2;
    server_name example.com www.example.com;
    
    ssl_certificate /etc/letsencrypt/live/example.com/fullchain.pem;
    ssl_certificate_key /etc/letsencrypt/live/example.com/privkey.pem;
    
    # SSL configuration
    ssl_protocols TLSv1.2 TLSv1.3;
    ssl_ciphers HIGH:!aNULL:!MD5;
    ssl_prefer_server_ciphers on;
    ssl_session_cache shared:SSL:10m;
    ssl_session_timeout 10m;
    
    # Security headers
    add_header Strict-Transport-Security "max-age=31536000; includeSubDomains" always;
    add_header X-Frame-Options "SAMEORIGIN" always;
    add_header X-Content-Type-Options "nosniff" always;
    
    # ... rest of server configuration ...
}

Configure automatic renewal:

# Certbot auto-renewal is configured by default
# Verify renewal service
sudo systemctl status certbot.timer

# Test renewal
sudo certbot renew --dry-run

Update PrestaShop settings for HTTPS:

mysql -u prestashop_user -p "SecurePassword123!" prestashop_db << EOF
UPDATE ps_configuration SET value = 'https://example.com/' WHERE name = 'PS_SHOP_DOMAIN_SSL';
UPDATE ps_configuration SET value = 'https://example.com/' WHERE name = 'PS_BASE_URL_SSL';
UPDATE ps_configuration SET value = 1 WHERE name = 'PS_SSL_ENABLED';
EOF

Recargue Nginx:

sudo nginx -t
sudo systemctl reload nginx

Optimización del rendimiento

Implement caching and optimization techniques for PrestaShop.

Instale and configure caching:

# Enable PrestaShop's built-in caching
mysql -u prestashop_user -p "SecurePassword123!" prestashop_db << EOF
UPDATE ps_configuration SET value = 'CacheMemcache' WHERE name = 'PS_CACHING';
UPDATE ps_configuration SET value = 'localhost' WHERE name = 'PS_CACHE_HOST';
UPDATE ps_configuration SET value = '11211' WHERE name = 'PS_CACHE_PORT';
EOF

Or use file-based caching:

mysql -u prestashop_user -p "SecurePassword123!" prestashop_db << EOF
UPDATE ps_configuration SET value = 'CacheFS' WHERE name = 'PS_CACHING';
EOF

Enable image optimization:

# Install ImageMagick
sudo apt install imagemagick -y

# PrestaShop will use ImageMagick for image processing
# Configure in admin panel: Performance > Image generation

Optimize database:

# Regular maintenance
mysql -u prestashop_user -p "SecurePassword123!" prestashop_db << EOF
OPTIMIZE TABLE ps_product;
OPTIMIZE TABLE ps_product_attribute;
OPTIMIZE TABLE ps_category_product;
OPTIMIZE TABLE ps_orders;
OPTIMIZE TABLE ps_order_detail;
OPTIMIZE TABLE ps_cart;
OPTIMIZE TABLE ps_cart_product;
EOF

Cree a maintenance script:

cat > /usr/local/bin/prestashop-maintenance.sh << 'EOF'
#!/bin/bash

# Database optimization
mysql -u prestashop_user -p "SecurePassword123!" prestashop_db << SQL
OPTIMIZE TABLE ps_product;
OPTIMIZE TABLE ps_orders;
OPTIMIZE TABLE ps_cart;
SQL

# Clear unnecessary caches
rm -rf /var/www/prestashop/var/cache/*
rm -rf /var/www/prestashop/var/logs/*

# Archive old logs
gzip /var/log/nginx/prestashop_access.log
gzip /var/log/php8.1-fpm-slow.log

echo "PrestaShop maintenance completed: $(date)" >> /var/log/prestashop-maintenance.log
EOF

sudo chmod +x /usr/local/bin/prestashop-maintenance.sh

Schedule maintenance:

sudo crontab -e

# Add daily maintenance at 2 AM
0 2 * * * /usr/local/bin/prestashop-maintenance.sh

Endurecimiento de seguridad

Implement security best practices to protect your PrestaShop installation.

Change default admin URL:

mysql -u prestashop_user -p "SecurePassword123!" prestashop_db << EOF
UPDATE ps_configuration SET value = 'admin-custom-path' WHERE name = 'PS_ADMIN_FOLDER';
EOF

Update Nginx configuration:

# Update admin location
location ~ ^/admin-custom-path/ {
    if (!-e $request_filename) {
        rewrite ^(.*)$ /admin-custom-path/index.php last;
    }
}

Configure WAF rules:

# Block common attack patterns
if ($request_uri ~* "\.\.") {
    return 403;
}

if ($request_uri ~* "drop database|insert |update |delete |select ") {
    return 403;
}

if ($request_method = "TRACE") {
    return 403;
}

Enable two-factor authentication in admin:

# PrestaShop provides 2FA in admin panel
# Navigate to: Advanced Parameters > Admin > 2FA

Regular backups:

cat > /usr/local/bin/prestashop-backup.sh << 'EOF'
#!/bin/bash

BACKUP_DIR="/backups/prestashop"
SHOP_DIR="/var/www/prestashop"
DB_NAME="prestashop_db"
DB_USER="prestashop_user"
DB_PASS="SecurePassword123!"

mkdir -p $BACKUP_DIR

# Backup database
mysqldump -u $DB_USER -p$DB_PASS $DB_NAME | gzip > $BACKUP_DIR/db-$(date +%Y%m%d-%H%M%S).sql.gz

# Backup files
tar czf $BACKUP_DIR/files-$(date +%Y%m%d-%H%M%S).tar.gz -C /var/www prestashop

# Keep only 30 days of backups
find $BACKUP_DIR -type f -mtime +30 -delete

echo "PrestaShop backup completed: $(date)" >> /var/log/prestashop-backup.log
EOF

sudo chmod +x /usr/local/bin/prestashop-backup.sh

Schedule backups:

# Run backups daily
sudo crontab -e

0 3 * * * /usr/local/bin/prestashop-backup.sh
