# Deploiement Backend Directus

Guide de deploiement du backend Directus sur un serveur Ubuntu.

## Prerequis

- Ubuntu 20.04+ / Debian 11+
- Acces root ou sudo
- Docker (ou Node.js 22+ pour une installation sans Docker)
- Nom de domaine configure (ex: `api.exemple.com`)

## 1. Installation des dependances

```bash
sudo apt update && sudo apt upgrade -y

# Docker
sudo apt install -y docker.io docker-compose-v2
sudo usermod -aG docker $USER
newgrp docker

# Nginx et Certbot
sudo apt install -y nginx certbot python3-certbot-nginx
```

## 2. Configuration du projet

```bash
# Cloner le projet
git clone <URL_DU_REPO> backend
cd backend

# Configurer l'environnement
cp .env.sample .env
nano .env
```

Variables a modifier dans `.env`:

```env
PUBLIC_URL="https://api.exemple.com"
KEY="<openssl rand -hex 32>"
SECRET="<openssl rand -hex 32>"
```

## 3. Preparation des volumes

```bash
mkdir -p database uploads extensions
chmod 755 database uploads extensions
```

## 4. Demarrage de Directus

```bash
docker compose up -d
docker compose ps
curl http://localhost:8055/server/health
```

## 5. Configuration Nginx

```bash
sudo nano /etc/nginx/sites-available/api.exemple.com
```

```nginx
server {
    listen 80;
    listen [::]:80;
    server_name api.exemple.com;

    client_max_body_size 100M;

    access_log /var/log/nginx/api.exemple.com.access.log;
    error_log /var/log/nginx/api.exemple.com.error.log;

    location / {
        proxy_pass http://127.0.0.1:8055;
        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;
        proxy_cache_bypass $http_upgrade;
        proxy_connect_timeout 600;
        proxy_send_timeout 600;
        proxy_read_timeout 600;
    }

    location /websocket {
        proxy_pass http://127.0.0.1:8055;
        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;
    }
}
```

Activer le site:

```bash
sudo ln -s /etc/nginx/sites-available/api.exemple.com /etc/nginx/sites-enabled/
sudo nginx -t && sudo systemctl reload nginx
```

## 6. Certificat SSL

Verifier le DNS:

```bash
dig +short api.exemple.com
curl -4 ifconfig.me
```

Obtenir le certificat:

```bash
sudo certbot --nginx -d api.exemple.com
```

## 7. Verification

```bash
curl https://api.exemple.com/server/health
```

Acces admin: `https://api.exemple.com/admin`

## Commandes utiles

```bash
# Logs
docker compose logs -f

# Redemarrer
docker compose restart

# Mise a jour
git pull origin main
docker compose down && docker compose up -d

# Backup base de donnees
cp database/data.db database/data.db.backup-$(date +%Y%m%d)

# Backup uploads
tar -czf uploads-backup-$(date +%Y%m%d).tar.gz uploads/
```

## Troubleshooting

### Erreur 502

```bash
docker compose ps
curl http://localhost:8055/server/health
sudo tail -20 /var/log/nginx/api.exemple.com.error.log
```

### Erreur SSL

```bash
dig +short api.exemple.com
sudo certbot certificates
sudo certbot renew --force-renewal
```
