[HowTo] Install this plugin with standalone node-red and without iobroker

[Catfriend1]

Hi,

I've managed to install the current release standalone to save a bit of RAM resources on my HA server. As I've google'd this for a longer time and found no advice/tutorial on how to do it WITHOUT iobroker, I now feel it might help other people to share the solution. Please feel free @datech to add this to the wiki if it's good for you.

• HOWTO : Install node-red-contrib-amazon-echo as a standalone nodered systemd service on Debian 10.10 "buster" amd64.

First, you maybe would like to uninstall iobroker. If not, skip this section.

systemctl stop iobroker
systemctl disable iobroker
#
rm -rf /etc/systemd/system/iobroker.service.d/
rm /lib/systemd/system/iobroker.service
systemctl daemon-reload
#
rm -rf /opt/iobroker/
#
userdel iobroker

Second, we do a fresh standalone installation of node-red.

#!/bin/sh
#
# Install nodejs
apt-get -y install curl
curl -sl "https://deb.nodesource.com/setup_14.x" | sudo -E bash -
apt-get install -y nodejs
node -v
#
# Install node-red
## Source
### https://nodered.org/docs/getting-started/local
npm install -g --unsafe-perm node-red
#
# Install alexa local device emulator
( mkdir -p /root/.node-red/; cd /root/.node-red; npm install node-red-contrib-amazon-echo )
#
# Start node-red
node-red
# Browser: http://192.168.x.y:1880/
# lsof -i -P
## tcp 80, udp 1900 LISTEN
#
# You may want to customize settings in "/root/.node-red/settings.js" to set up admin web UI authentication by username and password or bind the admin web UI of node-red to a specific network interface.
## Generate the admin password hash like this
### node-red admin hash-pw
#
exit 0

Third part: You may want to run node-red (with this plugin) automatically by systemd on system startup.

I've therefore created a systemd unit for Debian, based on this source: https://raw.githubusercontent.com/node-red/linux-installers/master/resources/nodered.service

Create the file: nano "/etc/systemd/system/nodered.service"

[Unit]
Description=Node-RED graphical event wiring tool
Wants=network.target
Documentation=https://raw.githubusercontent.com/node-red/linux-installers/master/resources/nodered.service

[Service]
Type=simple
User=root
Group=root
WorkingDirectory=/root
Environment="NODE_OPTIONS=--max_old_space_size=128"
ExecStartPre=/bin/bash -c '/bin/journalctl -b -u systemd-timesyncd | /bin/grep -q "systemd-timesyncd.* Synchronized to time server"'
# ExecStartPre=+/sbin/setcap 'cap_net_bind_service=+ep' /usr/bin/node
ExecStart=/usr/bin/env node-red $NODE_OPTIONS $NODE_RED_OPTIONS
KillSignal=SIGINT
Restart=on-failure
RestartSec=20
SyslogIdentifier=Node-RED

[Install]
WantedBy=multi-user.target

Then do: systemctl reload; systemctl enable nodered.service; systemctl start nodered.service

Kind regards,
