Many people asked how to update Node Red in Beaglebone. Current version is 3.0 and Beaglebone ships version 1.0…
Remove obsolete NodeRed installation so it won’t make troubles.
sudo apt remove bb-node-red-installer nodejs c9-core-installer
Now download current LTS NodeJS
cd /tmp
wget https://nodejs.org/dist/v18.16.0/node-v18.16.0-linux-armv7l.tar.xz
tar -xf node-v18.16.0-linux-armv7l.tar.xz
rm node-v18.16.0-linux-armv7l.tar.xz node-v18.16.0-linux-armv7l/README.md node-v18.16.0-linux-armv7l/LICENSE node-v18.16.0-linux-armv7l/CHANGELOG.md
cd node-v18.16.0-linux-armv7l
sudo cp -R * /usr/local/
Now run
node --version
And make sure that you have NodeJS which you installed.
Be logged in as Debian user! To install Node Red simply run:
npm install node-red
Now create 2 files:
/lib/systemd/system/nodered.service
/lib/systemd/system/nodered.socket
First file content (use eg sudo nano /lib/systemd/system/nodered.service )
[Unit]
Description=Node-RED graphical event wiring tool
Wants=network.target
Documentation=https://nodered.org/docs/
After=multi-user.target
[Service]
Type=simple
User=debian
Group=debian
RestartSec=250
Environment="NODE_PATH=/home/debian/node_modules"
Environment="NODE_OPTIONS=--max_old_space_size=256"
Environment="HOME=/home/debian/.node-red"
ExecStart=/usr/bin/env /usr/local/bin/node $NODE_OPTIONS /home/debian/node_modules/node-red/red.js $NODE_RED_OPTIONS
KillSignal=SIGINT
Restart=on-failure
SyslogIdentifier=Node-RED
[Install]
WantedBy=multi-user.target
Socket file content
[Unit]
Description=Node-RED Socket
PartOf=nodered.service
[Socket]
ListenStream=1880
[Install]
WantedBy=sockets.target
If both files are present then run:
sudo systemctl daemon-reload
sudo systemctl enable --now nodered
It’s done!
