# 🚀 Laca City Website - VPS Deployment Guide

This guide will help you deploy your Laca City website to a VPS with a custom domain using a single script.

## 📋 Prerequisites

### VPS Requirements
- **OS**: Ubuntu 20.04+ or Debian 11+
- **RAM**: Minimum 2GB (4GB recommended)
- **Storage**: Minimum 20GB SSD
- **CPU**: 2+ cores recommended
- **Root/Sudo access**: Required

### Domain Requirements
- Domain name pointed to your VPS IP address
- DNS A record: `yourdomain.com` → `your-vps-ip`
- DNS A record: `www.yourdomain.com` → `your-vps-ip`

### Before You Start
- [ ] VPS is running Ubuntu/Debian
- [ ] You have SSH access to your VPS
- [ ] Domain DNS is properly configured
- [ ] You have a valid email address for SSL certificate

## 🎯 Quick Deployment

### Step 1: Upload Files to VPS

```bash
# Option 1: Using SCP
scp -r /path/to/your/project your-user@your-vps-ip:/home/your-user/

# Option 2: Using rsync
rsync -avz --progress /path/to/your/project/ your-user@your-vps-ip:/home/your-user/project/

# Option 3: Using Git (if your project is on GitHub)
git clone https://github.com/your-username/your-repo.git
```

### Step 2: Run the Deployment Script

```bash
# SSH into your VPS
ssh your-user@your-vps-ip

# Navigate to your project directory
cd /path/to/your/project

# Run the deployment script
./vps-deploy.sh
```

### Step 3: Follow the Interactive Setup

The script will ask you for:
- **Domain name**: e.g., `lacacity.com`
- **Email**: For SSL certificate (e.g., `admin@lacacity.com`)
- **Database password**: Leave empty to auto-generate
