# ⚙️ Guide de Configuration - 4NK Node

Guide complet pour configurer l'infrastructure 4NK Node selon vos besoins.

## 📋 Configuration Générale

### 1. Variables d'Environnement

Créer un fichier `.env` à la racine du projet :


### 2. Configuration Réseau

#### Réseau Docker Personnalisé


#### Configuration de Pare-feu

## 🔧 Configuration Bitcoin Core

### 1. Configuration de Base


### 2. Configuration Avancée

#### Sécurité


## 🔧 Configuration SSL/TLS

### 1. Certificat Auto-Signé

```bash
# Générer un certificat auto-signé
openssl req -x509 -newkey rsa:4096 -keyout key.pem -out cert.pem -days 365 -nodes

# Configurer nginx comme proxy SSL
cat > nginx.conf << EOF
server {
    listen 443 ssl;
    server_name your-domain.com;

    ssl_certificate cert.pem;
    ssl_certificate_key key.pem;

    ssl_protocols TLSv1.2 TLSv1.3;
    ssl_ciphers ECDHE-RSA-AES256-GCM-SHA512:DHE-RSA-AES256-GCM-SHA512:ECDHE-RSA-AES256-GCM-SHA384:DHE-RSA-AES256-GCM-SHA384;
    ssl_prefer_server_ciphers off;

    location / {
        proxy_pass http://localhost:8090;
        proxy_http_version 1.1;
        proxy_set_header Upgrade \$http_upgrade;
        proxy_set_header Connection "upgrade";
        proxy_set_header Host \$host;
        proxy_set_header X-Real-IP \$remote_addr;
        proxy_set_header X-Forwarded-For \$proxy_add_x_forwarded_for;
        proxy_set_header X-Forwarded-Proto \$scheme;
    }
}
EOF
```

### 2. Certificat Let's Encrypt

```bash
# Installer certbot
sudo apt install certbot python3-certbot-nginx

# Obtenir un certificat
sudo certbot --nginx -d your-domain.com

# Configuration automatique
sudo certbot renew --dry-run
```

## 🔧 Configuration de Monitoring

### 1. Prometheus

```yaml
# docker-compose.yml addition
services:
  prometheus:
    image: prom/prometheus:latest
    container_name: prometheus
    ports:
      - "9090:9090"
    volumes:
      - ./prometheus.yml:/etc/prometheus/prometheus.yml
      - prometheus_data:/prometheus
    command:
      - '--config.file=/etc/prometheus/prometheus.yml'
      - '--storage.tsdb.path=/prometheus'
      - '--web.console.libraries=/etc/prometheus/console_libraries'
      - '--web.console.templates=/etc/prometheus/consoles'
      - '--storage.tsdb.retention.time=200h'
      - '--web.enable-lifecycle'

  grafana:
    image: grafana/grafana:latest
    container_name: grafana
    ports:
      - "3000:3000"
    volumes:
      - grafana_data:/var/lib/grafana
    environment:
      - GF_SECURITY_ADMIN_PASSWORD=admin

volumes:
  prometheus_data:
  grafana_data:
```

### 2. Configuration Prometheus

Fichier : `prometheus.yml`

```yaml
global:
  scrape_interval: 15s
  evaluation_interval: 15s

rule_files:
  # - "first_rules.yml"
  # - "second_rules.yml"

scrape_configs:
  - job_name: 'bitcoin'
    static_configs:
      - targets: ['bitcoin:18443']

  - job_name: 'blindbit'
    static_configs:
      - targets: ['blindbit:8000']

  - job_name: 'sdk_relay'
    static_configs:
      - targets: ['sdk_relay_1:8091']
```

## 🔧 Configuration de Sauvegarde

### 1. Script de Sauvegarde

```bash
#!/bin/bash
# backup_4nk.sh

DATE=$(date +%Y%m%d_%H%M%S)
BACKUP_DIR="/backup/4nk_node_$DATE"

mkdir -p $BACKUP_DIR
```

### 2. Configuration Cron

```bash
# Ajouter au cron pour sauvegarde automatique
```

## 🔧 Configuration de Logs

### 1. Rotation des Logs

```bash
# Configuration logrotate
```

### 2. Centralisation des Logs

```yaml
# docker-compose.yml addition
services:
  elasticsearch:
    image: docker.elastic.co/elasticsearch/elasticsearch:7.17.0
    container_name: elasticsearch
    environment:
      - discovery.type=single-node
    ports:
      - "9200:9200"
    volumes:
      - elasticsearch_data:/usr/share/elasticsearch/data

  kibana:
    image: docker.elastic.co/kibana/kibana:7.17.0
    container_name: kibana
    ports:
      - "5601:5601"
    depends_on:
      - elasticsearch

  filebeat:
    image: docker.elastic.co/beats/filebeat:7.17.0
    container_name: filebeat
    volumes:
      - /var/lib/docker/containers:/var/lib/docker/containers:ro
      - ./filebeat.yml:/usr/share/filebeat/filebeat.yml:ro
    depends_on:
      - elasticsearch

volumes:
  elasticsearch_data:
```
