  - Error logs: `/var/log/nginx/church-music-error.log`

### 5. Auto-Start on System Reboot ✅

Both services will automatically start when the server reboots:

```bash
sudo systemctl is-enabled church-music-backend  # enabled
sudo systemctl is-enabled nginx  # enabled
```

---

## 📊 Service Management Commands

### Check Status

```bash
# Backend status
sudo systemctl status church-music-backend

# Nginx status  
sudo systemctl status nginx

# Check if site is responding
curl http://localhost:5000/api/health
```

### Start/Stop/Restart Services

```bash
# Backend
sudo systemctl start church-music-backend
sudo systemctl stop church-music-backend
sudo systemctl restart church-music-backend

# Nginx
sudo systemctl restart nginx
sudo systemctl reload nginx  # Reload config without downtime
```

### View Logs

```bash
# Backend logs
tail -f /media/pts/Website/Church_HOP_MusicData/backend/logs/error.log
tail -f /media/pts/Website/Church_HOP_MusicData/backend/logs/access.log

# Nginx logs
sudo tail -f /var/log/nginx/church-music-access.log
sudo tail -f /var/log/nginx/church-music-error.log

# System journal (backend)
sudo journalctl -u church-music-backend -f
```

## 🚀 Performance Optimizations Applied

### Backend

- ✅ Gunicorn with 2 workers for concurrent requests
- ✅ PostgreSQL connection pooling (faster database queries)
- ✅ Memory limit: 512MB (prevents resource hogging)
- ✅ CPU quota: 50% (fair sharing with other websites)
- ✅ Debug mode disabled (production safety)

### Frontend

- ✅ Production build minified and optimized
- ✅ Gzip compression (70-80% file size reduction)
- ✅ Static file caching (reduces server load)
- ✅ Mobile-optimized CSS (3-column grid, touch gestures)
- ✅ ResizeObserver errors suppressed

### Database

- ✅ Connection pooling (10 base + 20 overflow)
- ✅ Pool pre-ping (verifies connections before use)
- ✅ Connection recycling (1 hour lifetime)

## 🔧 Multiple Websites on Same Server

Your server now runs **multiple websites simultaneously**:

1. **Church Music System** (Port 5000)
   - <http://localhost:5000>

2. **House of Prayer** (Port 8080)  
   - Your existing site (re-enabled)

3. **Sky Art Shop** (Other sites)
   - All coexisting peacefully!

**Resource allocation ensures fair sharing:**

- Each backend service has CPU and memory limits
- Nginx efficiently serves multiple sites
- PostgreSQL handles concurrent connections

## 🎯 Testing After Reboot

To verify auto-start works correctly:

```bash
# Reboot the server
sudo reboot

# After reboot, check services
sudo systemctl status church-music-backend
sudo systemctl status nginx

# Test the site
curl http://localhost:5000
curl http://localhost:5000/api/health
```

Everything should start automatically!

## 🔐 Security Notes

1. **Database**: Currently uses local PostgreSQL (not exposed to internet)
2. **Backend**: Only accessible via Nginx proxy (not exposed directly)
3. **Frontend**: Served with security headers (X-Frame-Options, XSS-Protection, etc.)
4. **Resource Limits**: Prevents any single service from consuming all server resources

---

## 📱 Mobile Features Included

- ✅ Login system (SHA-256 password hashing)
- ✅ 3-column song database grid on mobile
- ✅ Touch-optimized (44px minimum targets)
- ✅ Swipe-right gesture for back navigation  
- ✅ Responsive font sizing (clamp functions)
- ✅ Tap highlight removal (better UX)
