### systemd override (`/etc/systemd/system/ollama.service.d/override.conf`)

```ini
Environment=OLLAMA_HOST=0.0.0.0:11434
Environment=OLLAMA_MODELS=/data/ollama/models
Environment=OLLAMA_NUM_PARALLEL=2
Environment=OLLAMA_MAX_LOADED_MODELS=2
```

### Model terpasang

| Model | Ukuran | Dipakai untuk |
|-------|--------|---------------|
| `qwen2.5:7b` | 4.7 GB | Chat / RAG generation |
| `nomic-embed-text:latest` | 274 MB | Embedding (768-dim) |

## Firewall (UFW)

| Port | Action | From |
|------|--------|------|
| 22/tcp | ALLOW | Anywhere |
| 11434/tcp | ALLOW | `10.100.1.0/24` |

**Tidak** expose `11434` ke internet.

ollama pull nomic-embed-text
ollama pull qwen2.5:7b
systemctl enable --now ollama
```

Verifikasi:

```bash
curl -s http://127.0.0.1:11434/api/version
