Installing Node-RED on OpenBSD

In this tutorial, we will go through the steps to install Node-RED on OpenBSD. Node-RED is a visual tool for wiring together hardware devices, APIs, and online services to create IoT solutions.

Prerequisites

Before proceeding, make sure you have the following:

• A running instance of OpenBSD
• Access to the root user account or sudo privileges
• A working internet connection

Install Node.js

Node-RED requires Node.js to be installed on your system. If you don't have Node.js already installed, use the following command to install it:

sudo pkg_add node

This will install Node.js along with its dependencies.

Install Node-RED

Once Node.js is installed, we can move on to installing Node-RED.

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

This command will install Node-RED globally on your system.

Run Node-RED

To start Node-RED, use the following command:

node-red

You should see output similar to the following:

22 Jul 12:54:12 - [info] Starting flows
22 Jul 12:54:12 - [info] Started flows
22 Jul 12:54:12 - [info] Server now running at http://127.0.0.1:1880/

Note that Node-RED is now accessible at http://localhost:1880/.

Conclusion

Congratulations! You have successfully installed Node-RED on OpenBSD. You can now build IoT solutions using Node-RED.

If you want to self-host in an easy, hands free way, need an external IP address, or simply want your data in your own hands, give IPv6.rs a try!

Alternatively, for the best virtual desktop, try Shells!
