Running Node-RED install for user kitazaki at /home/kitazaki on ubuntu
This can take 20-30 minutes on the slower Pi versions - please wait.
Stop Node-RED ✔
Remove old version of Node-RED ✔
Remove old version of Node.js ✔
Install Node.js 16 LTS ✔ v16.20.0 Npm 8.19.4
Clean npm cache ✔
Install Node-RED core ✔ 3.0.2
Move global nodes to local -
Npm rebuild existing nodes ✔
Install extra Pi nodes ✔
Add shortcut commands ✔
Update systemd script ✔
Any errors will be logged to /var/log/nodered-install.log
All done.
You can now start Node-RED with the command node-red-start
or using the icon under Menu / Programming / Node-RED
Then point your browser to localhost:1880 or http://{your_pi_ip-address}:1880

**********************************************************************************
### WARNING ###
DO NOT EXPOSE NODE-RED TO THE OPEN INTERNET WITHOUT SECURING IT FIRST
Even if your Node-RED doesn't have anything valuable, (automated) attacks will
happen and could provide a foothold in your local network
Follow the guide at https://nodered.org/docs/user-guide/runtime/securing-node-red
to setup security.
### ADDITIONAL RECOMMENDATIONS ###
- You can customise the initial settings by running:
node-red admin init
- After running Node-RED for the first time, change the ownership of the settings
file to 'root' to prevent unauthorised changes:
sudo chown root:root ~/.node-red/settings.js

---------------------------------------------------------------------
Your flow credentials file is encrypted using a system-generated key.
If the system-generated key is lost for any reason, your credentials
file will not be recoverable, you will have to delete it and re-enter
your credentials.
You should set your own key using the 'credentialSecret' option in
your settings file. Node-RED will then re-encrypt your credentials
file using your chosen key the next time you deploy a change.
