sudo curl -fsSL https://download.docker.com/linux/ubuntu/gpg -o /etc/apt/keyrings/docker.asc
sudo chmod a+r /etc/apt/keyrings/docker.asc

# Add the repository to Apt sources:
echo \
  "deb [arch=$(dpkg --print-architecture) signed-by=/etc/apt/keyrings/docker.asc] https://download.docker.com/linux/ubuntu \
  $(. /etc/os-release && echo "$VERSION_CODENAME") stable" | \
  sudo tee /etc/apt/sources.list.d/docker.list > /dev/null
sudo apt-get update
```

```
sudo apt-get install docker-ce docker-ce-cli containerd.io docker-buildx-plugin docker-compose-plugin
```

**Step 3:** Install Node Version Manager

```php
nvm install 20.11.1 && nvm use 20.11.1
```

**Step 4: Clone ar.io repository**

```php

cd ar-io-node
```

**Step 5:** Modify your *.env*

```php
GRAPHQL_HOST=arweave.net
GRAPHQL_PORT=443
START_HEIGHT=0
RUN_OBSERVER=true
ARNS_ROOT_HOST=<your-domain>
AR_IO_WALLET=<your-gateway-wallet-address>
OBSERVER_WALLET=<hot-wallet-public-address(you can use same wallet)>
AO_CU_URL=https://cu.ardrive.io
ARNS_NAME_LIST_CACHE_MISS_REFRESH_INTERVAL_SECONDS=60

{% hint style="success" %}
Don’t forget to change *“Type”* and switch off “*Proxy”.*
{% endhint %}

**Step 7:** Get *acme\_challange* token for DNS Records.

```
sudo certbot certonly --manual --preferred-challenges dns --email <your-email-address> -d <your-domain> -d '*.<your-domain>'
```

{% hint style="success" %}
Note : Change email by your email and domain by your domain.
{% endhint %}

**Step 8:** Configure nginx on Server

```
sudo nano /etc/nginx/sites-available/default
```

```
# Force redirects from HTTP to HTTPS
server {
    listen 80;
    listen [::]:80;
    server_name <your-domain>.com *.<your-domain>;

    location / {
        return 301 https://$host$request_uri;
    }
}

# Forward traffic to your node and provide SSL certificates
server {
    listen 443 ssl;
    listen [::]:443 ssl;
    server_name <your-domain> *.<your-domain>;

    ssl_certificate /etc/letsencrypt/live/<your-domain>/fullchain.pem;
    ssl_certificate_key /etc/letsencrypt/live/<your-domain>/privkey.pem;

    location / {
        proxy_pass http://localhost:3000;
        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_http_version 1.1;
    }
