# Installation

This section documents every way to install and run a COTI full node from our tooling: the [**`/setup`** wizard](/coti-documentation/node-ecosystem/ui-guide.md) (`curl | sudo bash`), or **Git clone + Docker Compose** without the wizard. This hub page is the destination for **"Learn more about installation"** in the wizard. See [Networks](/coti-documentation/node-ecosystem.md#networks) for testnet and mainnet URLs.

{% hint style="info" %}
**OS and hardware** are the same on every path — see [**Server requirements**](/coti-documentation/node-ecosystem/server-requirements.md). **Without the web app**, use [**Manual full node setup**](/coti-documentation/node-ecosystem/installation/manual-full-node.md) (last page in this section).
{% endhint %}

## Certified operating system and hardware

The **same** certified OS and server sizing apply to every path in this section (wizard or manual). Full detail is on [**Server requirements**](/coti-documentation/node-ecosystem/server-requirements.md).

## Choose your installer flow

The wizard produces a one-liner that runs [`install_coti-full-node.sh`](https://github.com/coti-io/coti-full-node/blob/main/install_coti-full-node.sh). Pick the guide that matches the **flags** the wizard gives you. **Self-managed** install (no wizard) is the last row.

| Flow                    | When                                                                                                    | Guide                                                                                                               |
| ----------------------- | ------------------------------------------------------------------------------------------------------- | ------------------------------------------------------------------------------------------------------------------- |
| **COTI-managed tunnel** | COTI-assigned subdomain, **`--with-frp`**, no Nginx/Let’s Encrypt on your VM                            | [**Wizard tunnel (COTI subdomain)**](/coti-documentation/node-ecosystem/installation/installation-wizard-tunnel.md) |
| **Your own domain**     | Your DNS name, **`--nginx`**, Let’s Encrypt + Nginx on the host                                         | [**Own domain (Nginx + TLS)**](/coti-documentation/node-ecosystem/installation/installation-own-domain.md)          |
| **Manual (no wizard)**  | Clone [`coti-full-node`](https://github.com/coti-io/coti-full-node), scripts, Compose — not the web app | [**Manual full node setup**](/coti-documentation/node-ecosystem/installation/manual-full-node.md)                   |

{% hint style="danger" %}
Piping `curl` into `sudo bash` runs a remote script as **root**. Only use commands from the official wizard, served from `https://fullnode.testnet.coti.io` or `https://fullnode.mainnet.coti.io`. When in doubt, review the script in the [`coti-full-node`](https://github.com/coti-io/coti-full-node) repository.
{% endhint %}

## After any wizard install

* The node syncs from peers; the browser wizard polls peer discovery until your node appears.
* You enter the **warm-up** window before the node becomes **hot** and an NFT is minted — see the [Glossary](/coti-documentation/node-ecosystem/ui-guide/glossary.md).

For **restart / stop / logs** when you manage the repo yourself, see [**Manual full node setup → Restarting your node**](/coti-documentation/node-ecosystem/installation/manual-full-node.md#restarting-your-node).

## Optional flags (overview)

The [**Wizard tunnel**](/coti-documentation/node-ecosystem/installation/installation-wizard-tunnel.md) and [**Own domain**](/coti-documentation/node-ecosystem/installation/installation-own-domain.md) pages document flags in full. Quick reference:

| Flag                       | Typical use                                                                                                              |
| -------------------------- | ------------------------------------------------------------------------------------------------------------------------ |
| **`--with-frp`**           | Tunnel flow — see [Wizard tunnel](/coti-documentation/node-ecosystem/installation/installation-wizard-tunnel.md).        |
| **`--nginx`**              | Own domain + TLS on host — see [Own domain](/coti-documentation/node-ecosystem/installation/installation-own-domain.md). |
| `--without-nginx`          | Skip Nginx (advanced; often not reward-suitable with a BYO domain).                                                      |
| `--frpc` / `--without-frp` | FRPC without tunnel relaxations — see tunnel page.                                                                       |
| `--staging`                | Let’s Encrypt staging — only with `--nginx`.                                                                             |

For **manual** operation (restart, stop, logs, FAQ), see [**Manual full node setup**](/coti-documentation/node-ecosystem/installation/manual-full-node.md).
