php -r "
require_once 'bootstrap.php';
\$chat = new ChatServer();
echo 'Chat system: ✓\n';
"
```
### SSL Certificate (Production Recommended)
```bash
# Using Let's Encrypt (certbot)
sudo certbot --apache -d your-domain.com
# Or manual certificates
# Place fullchain.pem and privkey.pem in /etc/ssl/certs/
# Update Apache/Nginx config with SSL settings
```
---
## 🔍 Monitoring & Maintenance
### Log Monitoring
```bash
# View recent logs
tail -f logs/app.log
# Search for errors
grep "ERROR\|CRITICAL" logs/app.log
# Log rotation (add to cron)
0 0 * * * /usr/sbin/logrotate /etc/logrotate.d/dodgers
# Logrotate configuration (/etc/logrotate.d/dodgers)
/var/www/html/dodgers-iptv/logs/*.log {
daily
rotate 30
compress
delaycompress
missingok
notifempty
create 644 www-data www-data
postrotate
systemctl reload apache2 2>/dev/null || true
endscript
}
```
### Performance Monitoring
```bash
# Check PHP-FPM status
systemctl status php8.1-fpm
# Monitor resource usage
htop
# PHP performance metrics
php -r "
echo 'Memory limit: ' . ini_get('memory_limit') . PHP_EOL;
echo 'Max execution time: ' . ini_get('max_execution_time') . PHP_EOL;
echo 'Upload max size: ' . ini_get('upload_max_filesize') . PHP_EOL;
"
```
### Database Maintenance
```bash
# Database size check
ls -lh data/app.db
# Optimization (run weekly)
php -r "
require_once 'bootstrap.php';
\$db = Database::getInstance()->getConnection();
\$db->exec('VACUUM');
\$db->exec('REINDEX');
echo 'Database optimized!\n';
"
```
### Backup Strategy
```bash
#!/bin/bash
# Weekly backup script (/etc/cron.weekly/dodgers-backup)
BACKUP_DIR="/var/backups/dodgers"
TIMESTAMP=$(date +%Y%m%d_%H%M%S)
# Create backup directory
mkdir -p $BACKUP_DIR
# Database backup
sqlite3 data/app.db ".backup '$BACKUP_DIR/app_$TIMESTAMP.db'"
# Log archive
tar -czf $BACKUP_DIR/logs_$TIMESTAMP.tar.gz logs/
# Configuration backup
cp .env $BACKUP_DIR/env_$TIMESTAMP.bak
# Cleanup old backups (keep 30 days)
find $BACKUP_DIR -name "*.db" -mtime +30 -delete
find $BACKUP_DIR -name "*.tar.gz" -mtime +30 -delete
find $BACKUP_DIR -name "*.bak" -mtime +30 -delete
```
---
## 🚨 Troubleshooting
### Common Issues
#### 1. White Screen / 500 Error
```bash
# Check PHP error logs
tail -f /var/log/apache2/error.log
tail -f /var/log/php8.1-fpm.log
# Enable debug mode temporarily
# Set APP_ENV=development in .env
# Reload web server
systemctl reload apache2
```
#### 2. Database Connection Failed
```bash
# Check file permissions
ls -la data/app.db
# Test connection manually
php -r "
try {
\$pdo = new PDO('sqlite:data/app.db');
echo '✓ Database connection successful\n';
} catch(Exception \$e) {
echo '✗ Database error: ' . \$e->getMessage() . '\n';
}
"
```
#### 3. Chat Not Working
```bash
# Check SSE endpoint
curl -H "Accept: text/event-stream" "http://your-domain.com/?sse=1&user_id=test&csrf=test"
# Review chat logs
grep "chat\|ChatServer" logs/app.log
```
#### 4. High Memory Usage
```bash
# Monitor processes
ps aux | grep php
# Check PHP memory settings
php -r "echo 'Current memory_limit: ' . ini_get('memory_limit') . '\n';"
# Increase if needed (php.ini or .user.ini)
memory_limit = 256M
```
---
## 🔐 Security Hardening
### Additional Security Measures
```bash
# Install fail2ban for IP banning
sudo apt-get install fail2ban
# Configure fail2ban for application logs
# /etc/fail2ban/jail.local
[dodgers]
enabled = true
port = http,https
filter = dodgers
logpath = /var/www/html/dodgers-iptv/logs/app.log
maxretry = 3
bantime = 86400
# Create filter
# /etc/fail2ban/filter.d/dodgers.conf
[Definition]
failregex = ^.*SECURITY.*ip.*<HOST>.*$
ignoreregex =
```
### Firewall Configuration
```bash
# Allow only necessary ports
sudo ufw default deny incoming
sudo ufw default allow outgoing
sudo ufw allow ssh
sudo ufw allow 'Apache Full'
# Enable firewall
sudo ufw enable
```
---
## 🚀 Performance Optimization
### PHP-FPM Tuning
```ini
# /etc/php/8.1/fpm/pool.d/www.conf
[www]
user = www-data
group = www-data
listen = /run/php/php8.1-fpm.sock
listen.owner = www-data
listen.group = www-data
pm = dynamic
pm.max_children = 50
pm.start_servers = 5
pm.min_spare_servers = 5
pm.max_spare_servers = 35
pm.process_idle_timeout = 10s
# Memory and timeouts
php_admin_value[memory_limit] = 128M
request_terminate_timeout = 300
```
### OPCache Configuration
```ini
# /etc/php/8.1/fpm/conf.d/opcache.ini
zend_extension=opcache.so
opcache.enable=1
opcache.memory_consumption=128
opcache.max_accelerated_files=7963
opcache.revalidate_freq=0
opcache.fast_shutdown=1
opcache.enable_cli=1
```

## 📊 Monitoring
### Health Check Endpoint
Add to monitoring system:
```
Health Check: http://your-domain.com/?api=health
Response: {"status":"ok","timestamp":"2025-01-01T12:00:00Z"}
```
### Metrics Collection
```bash
# Log analysis
#!/bin/bash
LOG_FILE="logs/app.log"
echo "=== Dodgers IPTV Daily Report ==="
echo "Requests today: $(grep "$(date +%Y-%m-%d)" "$LOG_FILE" | wc -l)"
echo "Errors today: $(grep "$(date +%Y-%m-%d)" "$LOG_FILE" | grep -i error | wc -l)"
echo "Chat messages today: $(grep "$(date +%Y-%m-%d)" "$LOG_FILE" | grep "message_sent" | wc -l)"
echo "Database size: $(ls -lh data/app.db | awk '{print $5}')"
echo "Log size: $(ls -lh logs/app.log | awk '{print $5}')"
