# Running the Node

### Running the peer

Once you have downloaded all the required binaries, you'll have to run the node. We'll start by generating the bioauth key.

#### Bioauth key generation

Generate your bioauth key, the one that is to be used for enrolment and authentication.

```shell-session
$ humanode-peer key generate
Secret phrase:       drop find ginger chief worry trial electric sense long deer lock north
  Network ID:        substrate
  Secret seed:       0xd35f23dd8c1672467c57a55dcf8d6761dd2238fec489e1c8cf90c437b18aefce
  Public key (hex):  0xf8eb7c948e3889c3149296e5a25b25f98f4814e781968cf5876f8cab474d480f
  Account ID:        0xf8eb7c948e3889c3149296e5a25b25f98f4814e781968cf5876f8cab474d480f
  Public key (SS58): 5Hh5gnML29ZkoSgkrYCeMw8BC4tu5R6q7NgRWfXZnp1NZei3
  SS58 Address:      5Hh5gnML29ZkoSgkrYCeMw8BC4tu5R6q7NgRWfXZnp1NZei3
```

#### Bioauth key import

Copy the secret phrase and import it into Keystore.

```shell-session
$ humanode-peer key insert --key-type kbai --suri "$SECRET_PHRASE" \ 
      --chain chainspec.json --scheme sr25519
```

Where:

* `--key-type kbai` - bioauth key type used in the Humanode networks.
* `--suri "$SECRET_PHRASE"` - your secret phrase (i.e., mnemonic) from the previous command.
* `--chain chainspec.json` - path to the Humanode chain specification file.

### Run the tunnel

The humanode peer uses `9944` RPC endpoint by default. You are free to use any of your choices. But don't forget to explicitly specify the same port during the peer-run in case using a different one  from `9944`.

Run the tunnel using `ngrok-wrapper`

```shell-session
$ ngrok-wrapper 9944
```

### Run the peer

There are 2 options to run it:

* Using `--rpc-url-ngrok-detect` subcommand to automatically detect RPC URLs from `ngrok-wrapper` that you have already launched before.

  ```shell-session
  $ humanode-peer --name "$NAME" --validator --chain chainspec.json \ 
        --rpc-url-ngrok-detect --rpc-cors all
  ```
* You can manually specify RPC URL from `ngrok-wrapper` output console.

  <pre class="language-shell-session"><code class="lang-shell-session"><strong>$ humanode-peer --name "$NAME" --validator --chain chainspec.json \
  </strong>      --rpc-url "$RPC_URL" --rpc-cors all
  </code></pre>

Where:

* `--name "$NAME"` - where `$NAME` is your Humanode peer name.
* `--validator` - means that you join the network as a block producer.
* `--chain chainspec.json` - a path to the file that contains the Humanode chain specification.
* `--rpc-url "$RPC_URL"` - the peer's RPC URL, where `$RPC_URL` is the URL that you noted at the `ngrok-wrapper` configuration step, or your own URL if you're not using `ngrok-wrapper`.
* `--rpc-url-ngrok-detect` - to detect peer's RPC URL automatically from `ngrok-wrapper` (mutually exclusive with `--rpc-url`).

{% hint style="info" %}
We strongly recommend using `--rpc-url-ngrok-detect` subcommand to avoid facing unexpected issues.

Your node has been installed and configured successfully. Now move to the [validator](https://gitbook.humanode.io/mainnet-guide/validator "mention").
