# Siapkan Sertifikat

## Buat URL Route 53

Buat URL Route 53 dari domain Anda, mis. caesar.internal.romeprotocol.xyz, agar mengarah ke IP server EC2.

## Buka Port

Pastikan port HTTP (80) dan HTTPS (443) terbuka di server jarak jauh Anda.

Gunakan firewall atau security group penyedia cloud Anda untuk membuka port-port ini.

## Dapatkan Sertifikat

CLI Certbot di bawah ini memungkinkan Anda mendapatkan sertifikat Lets Encrypt.

**Catatan: Gunakan alamat email dan nama domain Anda sendiri saat meminta sertifikat.**

<pre class="language-bash"><code class="lang-bash">sudo apt install -y nginx
sudo snap install --classic certbot
sudo ln -s /snap/bin/certbot /usr/bin/certbot
<strong>sudo certbot certonly --nginx -n -m rome@romeprotocol.com --agree-tos --domains caesar.internal.romeprotocol.xyz # Ganti dengan email dan domain Anda
</strong>sudo nginx -s stop
</code></pre>

## Verifikasi pembuatan sertifikat

Sekarang, pastikan file fullchain.pem dan privkey.pem berada di direktori di bawah ini.

```bash
sudo ls /etc/letsencrypt/live/caesar.internal.romeprotocol.xyz
```
