## 🔧 What Was Fixed

### 1. File Permissions
**Problem:** Files owned by `theophile:theophile` with 640 permissions, nginx couldn't read them.

**Solution:**
```bash
# Changed group to posterg (www-data is member)
chown -R theophile:posterg /var/www/html/

# Set proper permissions
find /var/www/html -type d -exec chmod 755 {} \;
find /var/www/html -type f -exec chmod 640 {} \;
```

### 2. PHP Include Paths
**Problem:** Public files used `../../shared/` which doesn't work in production structure.

**Solution:**
- Public files: Changed `../../shared/` → `/shared/`
- Admin files: Changed `../../shared/` → `/../shared/`
- Automated in deployment script

### 3. Nginx Configuration
**Problem:** Using basic default config with no security.

**Solution:** Deployed production config with:
- ✅ Rate limiting (30/min general, 10/min admin)
- ✅ File protection (database, configs, hidden files)
- ✅ Admin password protection
- ✅ Security headers
- ✅ Proper PHP-FPM configuration
- ✅ Upload size limits (100MB)

## 🚀 Deployment Process (For Future Updates)

The deployment process has been automated and updated:

### Deploy Code Changes

```bash
# Deploy public site
just deploy-public
# Automatically fixes paths: ../../shared/ → /shared/

# Deploy admin panel
just deploy-admin
# Automatically fixes paths: ../../shared/ → /../shared/

# Deploy both
just deploy
```

### Deploy Nginx Config

```bash
# Deploy production nginx configuration
just deploy-nginx-production

# On server, run deployment script
ssh posterg
sudo bash /tmp/deploy-production.sh
```

The deployment scripts now automatically:
1. ✅ Copy files to server
2. ✅ Fix PHP include paths
3. ✅ Set correct permissions
4. ✅ Test nginx configuration
5. ✅ Reload services

---

## 🧪 Testing & Verification

### Automated Tests

```bash
# On server
cd /var/www/html

# Test public site
curl -I http://localhost/                # Should: 200 OK

# Test admin protection
curl -I http://localhost/formulaire/     # Should: 401 Unauthorized

# Test security
curl -I http://localhost/database/posterg.db   # Should: 403 Forbidden
curl -I http://localhost/README.md             # Should: 403 Forbidden
curl -I http://localhost/shared/Database.php   # Should: 403 Forbidden
```

### External Tests

```bash
# From your local machine
curl -I https://posterg.erg.be/           # Should: 200 OK
curl -I https://posterg.erg.be/formulaire/  # Should: 401
```

### Browser Tests

1. ✅ Visit https://posterg.erg.be/ - Homepage loads
2. ✅ Search functionality works
3. ✅ Individual thesis pages work
4. ✅ Admin requires password: https://posterg.erg.be/formulaire/
5. ✅ Can upload files in admin (after login)

## 📊 Monitoring

### Log Files

```bash
# Nginx access log
tail -f /var/log/nginx/posterg_access.log

# Nginx error log
tail -f /var/log/nginx/posterg_error.log

# PHP error log
tail -f /var/www/html/error.log
```

### Service Status

```bash
# Check nginx
sudo systemctl status nginx

# Check PHP-FPM
sudo systemctl status php8.4-fpm

# Test nginx config
sudo nginx -t
```

---

## 🔐 Admin Access

### Login Credentials
- **URL:** https://posterg.erg.be/formulaire/
- **Username:** `test_posterg_22@`
- **Password:** Set during deployment (stored securely)

### Change Password

```bash
ssh posterg
sudo htpasswd /etc/nginx/.htpasswd-posterg test_posterg_22@
```

### Add Additional Admin Users

```bash
ssh posterg
sudo htpasswd /etc/nginx/.htpasswd-posterg newusername
```

---

## 🔄 Maintenance

### Update Website Content

```bash
# From local machine
just deploy

# Content is automatically updated on server
```

### Reload Nginx (after config changes)

```bash
ssh posterg
sudo nginx -t                    # Test configuration
sudo systemctl reload nginx      # Reload if test passes
```

### Restart PHP-FPM (if needed)

```bash
ssh posterg
sudo systemctl restart php8.4-fpm
```

### Update SSL Certificate

SSL/TLS is handled by the upstream reverse proxy. Contact the infrastructure team if certificate renewal is needed.

---

## 🆘 Troubleshooting

### Site Returns 403 Forbidden

**Check file permissions:**
```bash
ls -la /var/www/html/index.php
# Should show: -rw-r----- theophile posterg
```

**Check nginx user:**
```bash
groups www-data
# Should show: www-data posterg
```

### Site Returns 500 Internal Server Error

**Check PHP errors:**
```bash
tail -f /var/log/nginx/posterg_error.log
tail -f /var/www/html/error.log
```

**Check PHP-FPM:**
```bash
sudo systemctl status php8.4-fpm
sudo systemctl restart php8.4-fpm
```

### Admin Panel Not Working

**Check password file:**
```bash
ls -la /etc/nginx/.htpasswd-posterg
```

**Reset password:**
```bash
sudo htpasswd /etc/nginx/.htpasswd-posterg test_posterg_22@
```

### After Deploying, Site Broken

**Check if paths were fixed:**
```bash
grep "require_once" /var/www/html/index.php
# Should show: __DIR__ . '/shared/Database.php'
# NOT: __DIR__ . '/../../shared/Database.php'
```

**Manually fix if needed:**
```bash
ssh posterg "cd /var/www/html && sed -i \"s|__DIR__ . '/../../shared/|__DIR__ . '/shared/|g\" *.php"
```
