Introduction

Welcome to the ultimate guide on how to run OpenClaw on a server. As AI adoption scales rapidly, developers and automation builders are constantly seeking robust, uninterrupted environments to run complex, intelligent workflows. Enter OpenClaw, a powerful AI automation workflow tool that is frequently compared to industry giants like n8n and Zapier (for a deeper dive, check out our OpenClaw vs n8n AI Automation Comparison).

While running OpenClaw locally on your desktop is fine for initial testing or small scripts (perhaps alongside your Local AI Agent with Python, Ollama, Langchain & RAG), transitioning to a Virtual Private Server (VPS) unlocks massive advantages. An OpenClaw VPS setup offers unparalleled benefits, including:

24/7 Automation Workflows: Your AI agents never sleep. A VPS guarantees that time-sensitive triggers and WebHooks run reliably around the clock.
Stable Uptime: Avoid the disruptions associated with local machine reboots, sleep modes, or sudden internet outages.
Remote Access: Access your OpenClaw execution environment globally from any device, streamlining remote collaboration.
Scalable AI Agents: As your computing needs grow, especially when processing heavy language models or large datasets, you can scale your VPS hardware in just a few clicks.

In this comprehensive OpenClaw installation guide, we will walk you through a complete, step-by-step process to seamlessly install OpenClaw on Ubuntu.

Requirements to Run OpenClaw on VPS

Before diving into the OpenClaw VPS setup, you must ensure that your server meets the necessary technical specifications. AI automation tools often require a reasonable amount of memory and processing power to juggle Node.js instances, database interactions, and API communications concurrently.

Here are the recommended minimum and ideal system specs for a dedicated server environment:

Component	Minimum Requirement	Recommended specs (For Production)
RAM	2 GB	4 GB+ (Essential for heavy concurrent workflows)
CPU	1 Core	2 Cores+ (Handles multiple API integrations smoother)
Storage	20 GB SSD	40 GB SSD+ (Logs and agent data can accumulate quickly)
OS	Ubuntu 22.04 LTS	Ubuntu 22.04 LTS (Highest compatibility)
Node.js	v18+	Latest LTS Version (v20+)

Choosing the right Cloud hosting provider is completely up to your preference, but some developer-friendly favorites that offer robust Linux servers include:

DigitalOcean (Great documentation and simple droplets)
Linode (Akamai) (Excellent performance and pricing)
Vultr (High-frequency compute instances)
AWS / Google Cloud (For enterprise-grade scalability)

Step 1 – Create a VPS Server

The first critical step in our OpenClaw installation guide is provisioning the Cloud server itself. For this tutorial, we will operate under the assumption that you are using a standard Ubuntu installation. Ubuntu 22.04 LTS is currently the gold standard for most modern Node.js applications and open-source automation platforms.

Provisioning Steps:

Sign up with a trusted VPS provider like DigitalOcean or Linode.
Create a new server instance (often called a 'Droplet' or 'Compute Instance').
Select Ubuntu 22.04 as your operating system image.
Choose a plan with at least 2GB RAM (4GB recommended if you plan to connect multiple AI APIs, like in our OpenRouter API tutorial).
Deploy the server. Once fully booted, the provider will allocate a public IP address. Copy this IP address.

Note: You will generally be provided with a root password or prompted to add an SSH key during creation. SSH keys are vastly superior for security.

Connecting via SSH:

Open your local terminal (Command Prompt, PowerShell, or macOS/Linux Terminal) and use the Secure Shell (SSH) protocol to log in:

ssh root@your-server-ip

You may be prompted to accept the server's fingerprint. Type "yes" and hit Enter. If you used a password, type it in (it won't show on screen for security purposes). Once authenticated, you will have complete command-line access to your server.

Step 2 – Install System Dependencies

Before you install OpenClaw on Ubuntu, your fresh server needs to be updated, and the foundational software must be installed. OpenClaw relies heavily on Node.js to execute its event loops and manage API requests efficiently.

Updating the System

Always start by ensuring your server's package manager has the latest software lists and upgrades existing packages to patch any security vulnerabilities:

sudo apt update && sudo apt upgrade -y

Installing Node.js and NPM

The default Ubuntu repositories sometimes carry older versions of Node.js. OpenClaw strictly requires Node version 18 or higher. We will utilize the NodeSource repository script to fetch a modern, compatible version.

curl -fsSL https://deb.nodesource.com/setup_18.x | sudo -E bash -
sudo apt install nodejs -y

If you prefer using newer features associated with recent releases, you can switch setup_18.x to setup_20.x in the command above.

Verifying the Installation

Confirm that both Node.js and the Node Package Manager (NPM) were successfully installed by checking their output versions:

node -v
npm -v

The output should return version numbers matching or exceeding v18.x and v9.x respectively.

Step 3 – Install OpenClaw

Now comes the pivotal moment to run OpenClaw on your server. We will clone the official repository directly from GitHub and install all required underlying packages.

Cloning the Repository

Make sure you are in a reasonable directory (like your home folder or /opt/) and use Git to clone the source code:

git clone https://github.com/openclaw/openclaw.git
cd openclaw

Installing Application Dependencies

Once inside the OpenClaw directory, use NPM to install all the dependencies defined in the project's package.json file. This process may take a minute or two as it fetches thousands of tiny libraries.

npm install

Testing the Server Temporarily

To ensure everything is working correctly, you should attempt to start the server normally before setting up a continuous background process:

npm start

When you execute this command, you should observe terminal logs indicating that the OpenClaw server has successfully started, the automation engine has loaded into memory, and the dashboard port is mapped. Once confirmed, press CTRL + C to stop the temporary server.

By the way, if you are planning to extend OpenClaw to messaging apps, be sure to read our OpenClaw WhatsApp Automation Guide.

Step 4 – Run OpenClaw with Process Manager (PM2)

If you simply use npm start and close your SSH terminal session, your OpenClaw execution will immediately terminate. To achieve true OpenClaw automation on VPS, we need an advanced process manager that keeps the application alive in the background and restarts it automatically if it ever crashes.

Enter PM2 – an industry standard production process manager for Node.js.

Installing PM2

Install PM2 globally across your server using NPM:

sudo npm install -g pm2

Starting OpenClaw in the Background

Make sure you are still inside your /openclaw directory, and execute the following command to hand control over to PM2. We are naming the process "openclaw" for easy identification later:

pm2 start npm --name openclaw -- start

Enable Automatic Startup on Server Reboot

If your VPS provider performs routine maintenance or there is an unexpected crash resulting in a server reboot, you want OpenClaw to boot up alongside Ubuntu.

pm2 startup
pm2 save

Executing pm2 startup will generate a custom command for your exact Ubuntu environment. Copy and paste the resulting command into your terminal, then run pm2 save to freeze the current process list.

Step 5 – Access OpenClaw Dashboard

Congratulations! OpenClaw is officially humming quietly in the background of your VPS. It is time to dive into the user interface.

Open any modern web browser and navigate to your server's IP address on the default port, which is 3000:

http://your-server-ip:3000

Dashboard Features

Within the intuitive GUI, developers can begin executing tasks immediately:

Create automation workflows: Map out logical sequences using a drag-and-drop designer.
Connect APIs: Securely link third-party services via OAuth or API keys.
Manage AI agents: If you are interested in pushing AI boundaries, you can structure dedicated autonomous sub-agents. See our post on OpenClaw & Claude Code Setup to supercharge reasoning capabilities.
Trigger workflows: Test your automations in real-time or set them on cron schedules.

Step 6 – Secure Your OpenClaw VPS

A bare-bones OpenClaw VPS setup gets the job done for prototypes, but for production environments or enterprise applications like an AI Resume Analyzer platform or AI Resume Builders, leaving ports wide open is a severe security risk.

Configuring UFW (Uncomplicated Firewall)

We need to lock down the server so it only accepts traffic on the ports we explicitly trust. Ubuntu comes with UFW built-in.

sudo ufw allow 22
sudo ufw allow 3000
sudo ufw enable

Type "y" when warned about disrupting existing SSH connections (allowing port 22 prevents you from locking yourself out).

(Optional) Reverse Proxy and SSL Certificates

Accessing your app via an IP address on port 3000 is unprofessional and insecure since data isn't encrypted. For commercial setups (e.g. platforms optimizing Resumes for Remote Jobs or running AI Interview Platforms), you should proxy the traffic using Nginx and secure it with a free SSL certificate.

This involves installing Nginx, pointing a domain name to your VPS IP, configuring a reverse proxy block in /etc/nginx/sites-available/ to forward port 80/443 traffic to port 3000, and running Let's Encrypt Certbot.

Common OpenClaw Errors on VPS

Running server-side automation engines isn't without its occasional hiccups. Here are the most prominent issues developers face during an OpenClaw installation guide walkthrough, along with rapid troubleshooting tips.

Error: "OpenClaw disconnected (1008) pairing required"

Cause: This websocket-related error frequently surfaces when your VPS loses connection to an active worker node, or when authentication tokens expire unexpectedly. It can also trigger when sitting behind a strict reverse proxy without proper WebSocket header forwarding.

Fix: Verify your proxy headers (specifically Upgrade and Connection "upgrade" for Nginx). Also, try clearing your browser cookies and restarting the PM2 process: pm2 restart openclaw.

Error: "OpenClaw gateway connect failed"

Cause: Generally caused by aggressive firewall rules blocking outbound or inbound API requests, or incorrectly defined environment variables (such as a wrong localhost IP in the .env file).

Fix: Check your UFW status using sudo ufw status. Double-check your .env file settings inside the OpenClaw directory to ensure no external endpoints are malformed.

Error: "OpenClaw workflow execution failed"

Cause: Your server might be exhausting its RAM (exceeding that 2GB minimum), or an external REST API simply timed out.

Fix: Run the command htop on your VPS to analyze active CPU/RAM usage. Consider upgrading your VPS plan to 4GB of RAM if the engine consistently crashes during heavy payload executions.

Conclusion

Deploying powerful orchestration software doesn't have to be a painful ordeal. As demonstrated, you can comfortably run OpenClaw on a server in virtually 10 to 15 minutes. By shifting off your local desktop and onto an Ubuntu VPS environment powered by Node.js and PM2, you unlock an ecosystem capable of rendering 24/7 AI automation workflows flawlessly.

The OpenClaw VPS setup guarantees that your integrations, webhooks, and AI agents run uninhibited by daily machine restarts or local networking woes. Now that your environment is fully primed and secured, we highly encourage developers to aggressively experiment with AI workflow mapping. Build smarter, automate heavily, and push the limits of what a dedicated AI execution server can accomplish.
