How to Install Node-RED on Fedora CoreOS Latest

Node-RED is a programming tool designed for connecting hardware devices, APIs and online services. In this tutorial, we will guide you through the steps to install Node-RED on Fedora CoreOS.

Prerequisites

• A Fedora CoreOS installation
• Access to a terminal window or SSH client

Installation Steps

1. Begin by opening a terminal window or connecting your SSH client to your Fedora CoreOS instance.

2. It is recommended that you update your package repositories before installing any new software. Use the following command to achieve this:

sudo dnf update

3. Then, ensure that all the necessary prerequisites are installed. Use this command to install the necessary software:

sudo dnf install -y @development-tools openssl-devel zlib-devel

4. Next, install Node.js. Fedora CoreOS has several methods to install Node.js, such as using the Node.js package or using nvm to install Node.js locally. In this tutorial, we will use the Official Fedora package.

sudo dnf install nodejs

5. Verify the installation by checking the Node.js version with the following command:

node -v

6. Finally, install Node-RED with the following command:

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

7. After the installation, you can start Node-RED using the following command:

node-red

8. By default, Node-RED will listen on port 1880 on all available network interfaces. If the firewall is active, then you need to open the port 1880. Use the following command to achieve this:

sudo firewall-cmd --add-port=1880/tcp --permanent

sudo firewall-cmd --reload

9. Now, you can access the Node-RED user interface by opening a web browser and navigating to http://[your_server_IP]:1880.

Congratulations! You have successfully installed Node-RED on your Fedora CoreOS instance. You can now experiment with different flows, or create your own flow with hardware devices, APIs, and online services.
