# Install on Linux

> Install the Collector as a systemd service with one command.

The Collector installs directly onto a Linux host (`amd64` or `arm64`) and runs as a systemd service. This is the default install path.

## Before you start

* A Linux host with systemd that meets the sizing in [Size the host](/deploy/sizing) and the network requirements in [Network requirements](/deploy/network-requirements).
* Root access (`sudo`) and `curl`.
* An enrolment token: in the portal, go to **Collectors → Add Collector** and name the Collector. The portal issues a **single-use token** and a ready-to-paste install command.

## Run the installer

Paste the command from the portal onto your host:

```bash theme={null}
curl -fsSL https://[portal-host]/public/collectors/install.sh \
  | sudo AV_ENROLL_TOKEN=[one-time-token] bash
```

The installer:

1. Checks the host for root access, `curl` and systemd.
2. Redeems the token with M.A.R.C.U.S. Cloud and receives the Collector's identity and HMAC key.
3. Creates a dedicated non-root `av-bridge` system user.
4. Installs the Collector binary and writes its configuration.
5. Registers and starts `av-bridge.service`, then waits for the local health check to pass.

The Collector then downloads its device list from the cloud automatically. The whole process typically takes **under 15 minutes**.
