In this tutorial, we will go through the steps to install Node-RED on Alpine Linux Latest. Node-RED is a powerful tool used for building applications and services for the internet of things. It allows you to connect different hardware devices, APIs, and online services to create complex workflows and automations.
The first step is to update and upgrade your system's packages to the latest versions.
$ sudo apk update && sudo apk upgrade
Next, you need to install Node.js, as it is the prerequisite for installing Node-RED.
$ sudo apk add nodejs npm
Verify that Node.js and npm are installed correctly by checking their versions.
$ node -v && npm -v
Now, you can install Node-RED by running the following command:
$ sudo npm install -g --unsafe-perm node-red
The installation process may take a few minutes to complete. During the installation, several modules will be downloaded and installed as well.
Once the installation is complete, you can test Node-RED by running the following command:
$ node-red
This will start Node-RED on your Alpine Linux. If Node-RED starts successfully, you will see output similar to the following:
Started Node-RED
...
Once Node-RED is running, you can open up a web browser and enter the following URL to access the Node-RED editor:
http://127.0.0.1:1880
To start Node-RED automatically on system boot, you can create a systemd unit file.
$ sudo nano /etc/systemd/system/node-red.service
Copy and paste the below content with modification if required.
[Unit]
Description=Node-RED
Wants=network.target
[Service]
Type=simple
User=root
Group=root
WorkingDirectory=/usr/lib/node_modules/node-red/
ExecStart=/usr/bin/env node-red-pi --max-old-space-size=256 -v
Restart=on-failure
[Install]
WantedBy=multi-user.target
Save the file and close it. Now reload the systemd configuration by running:
$ sudo systemctl daemon-reload
Next, start the service and enable it to start at boot.
$ sudo systemctl start node-red.service
$ sudo systemctl enable node-red.service
Check the status of the service by running:
$ sudo systemctl status node-red.service
Once you've completed these steps, your system will be running Node-RED as a service. Try interacting with the editor at http://127.0.0.1:1880 to ensure everything is working properly.
In this tutorial, we have walked through the steps to install Node-RED on Alpine Linux Latest. You can now start building amazing applications and services using Node-RED on your Alpine Linux Latest machine.
