DigitalOcean

Run a persistent OpenClaw Gateway on a DigitalOcean Droplet.

Prerequisites

  • DigitalOcean account (signup)
  • SSH key pair (or willingness to use password auth)
  • About 20 minutes

安装配置

Use a clean base image (Ubuntu 24.04 LTS). Avoid third-party Marketplace 1-click images unless you have reviewed their startup scripts and firewall defaults. 

1. Log into [DigitalOcean](https://cloud.digitalocean.com/).
2. Click **Create > Droplets**.
3. Choose:
   * **Region:** Closest to you
   * **Image:** Ubuntu 24.04 LTS
   * **Size:** Basic, Regular, 1 vCPU / 1 GB RAM / 25 GB SSD
   * **Authentication:** SSH key (recommended) or password
4. Click **Create Droplet** and note the IP address.

“`bash theme={“theme”:{“light”:”min-light”,”dark”:”min-dark”}}
ssh root@YOUR_DROPLET_IP

apt update && apt upgrade -y

# Install Node.js 24
curl -fsSL https://deb.nodesource.com/setup_24.x | bash -
apt install -y nodejs

# Install OpenClaw
curl -fsSL https://openclaw.ai/install.sh | bash
openclaw --version
```

bash theme={"theme":{"light":"min-light","dark":"min-dark"}}
openclaw onboard --install-daemon

The wizard walks you through model auth, channel setup, gateway token generation, and daemon installation (systemd).

bash theme={"theme":{"light":"min-light","dark":"min-dark"}}
fallocate -l 2G /swapfile
chmod 600 /swapfile
mkswap /swapfile
swapon /swapfile
echo '/swapfile none swap sw 0 0' >> /etc/fstab

bash theme={"theme":{"light":"min-light","dark":"min-dark"}}
openclaw status
systemctl --user status openclaw-gateway.service
journalctl --user -u openclaw-gateway.service -f

The gateway binds to loopback by default. Pick one of these options.

**Option A: SSH tunnel (simplest)**

```bash  theme={"theme":{"light":"min-light","dark":"min-dark"}}
# From your local machine
ssh -L 18789:localhost:18789 root@YOUR_DROPLET_IP
```

Then open `http://localhost:18789`.

**Option B: Tailscale Serve**

```bash  theme={"theme":{"light":"min-light","dark":"min-dark"}}
curl -fsSL https://tailscale.com/install.sh | sh
tailscale up
openclaw config set gateway.tailscale.mode serve
openclaw gateway restart
```

Then open `https://<magicdns>/` from any device on your tailnet.

**Option C: Tailnet bind (no Serve)**

```bash  theme={"theme":{"light":"min-light","dark":"min-dark"}}
openclaw config set gateway.bind tailnet
openclaw gateway restart
```

Then open `http://<tailscale-ip>:18789` (token required).

故障排查

Gateway will not start — Run openclaw doctor --non-interactive and check logs with journalctl --user -u openclaw-gateway.service -n 50.

Port already in use — Run lsof -i :18789 to find the process, then stop it.

Out of memory — Verify swap is active with free -h. If still hitting OOM, use API-based models (Claude, GPT) rather than local models, or upgrade to a 2 GB Droplet.
