Installing and Configuring Node-RED for IoT Projects on ServerStadium

This tutorial will guide you through setting up Node-RED on a ServerStadium VM or dedicated server, which is ideal for developing and managing IoT applications.


Step 1: Set Up Your ServerStadium VM or Dedicated Server

  1. Server Selection and Setup: Choose a VM or dedicated server from ServerStadium. For most IoT projects, a small to medium-sized VM will suffice.
  2. Initial Server Configuration: Connect to your server via SSH. Update and upgrade your system:

    sudo apt update
    sudo apt upgrade

Step 2: Install Node.js

Node-RED is built on Node.js. Install Node.js on your server:

  1. Add Node.js Repository:

    curl -sL | sudo -E bash –

  2. Install Node.js:

    sudo apt install -y nodejs

  3. Verify Installation:

    node –version
    npm –version

Step 3: Install Node-RED

Install Node-RED using npm:

sudo npm install -g –unsafe-perm node-red

Step 4: Start Node-RED

Start Node-RED:


Node-RED will now be running on your server on port 1880.

Step 5: Access Node-RED

Access Node-RED by navigating to http://your_server_ip:1880 in your web browser.

Step 6: Secure Node-RED

It’s essential to secure your Node-RED editor, especially if it’s accessible over the Internet:

  1. Stop Node-RED:If Node-RED is running, stop it with Ctrl+C in your terminal.
  2. Secure with a Password:Run the following command to generate a password hash:

    node-red-admin hash-pw

    Enter your desired password and copy the generated hash.
  3. Edit Node-RED Settings:Edit the Node-RED settings file:

    nano ~/.node-red/settings.js

    Under the adminAuth section, set up a user with your hashed password:

    adminAuth: {
    type: "credentials",
    users: [{
    username: "admin",
    password: "your_hashed_password",
    permissions: "*"

  4. Restart Node-RED:


Step 7: Configure for IoT Projects

  1. Install Additional Nodes: Depending on your IoT project, you may need additional nodes (like MQTT, HTTP, or WebSocket). These can be installed via the Node-RED palette manager in the web interface.
  2. Flow Configuration: Create and configure flows to process data from your IoT devices, integrate with various services, or execute automation tasks.


Your Node-RED instance is now set up and secured on a ServerStadium server, ready for IoT projects. You can build and manage complex IoT workflows using its intuitive interface.
