RPi 3 installation

Robert126 · 13 March 2020 20:13

I followed

This installation
https://nodered.org/docs/getting-started/raspberrypi
I trying to make it secure following this link:
https://nodered.org/docs/user-guide/runtime/securing-node-red#user-permissions

I Cann't run the following command:'

node-red-admin hash-pw

or

node -e "console.log(require('bcryptjs').hashSync(process.argv[1], 8));" your-password-here

Hopefully some one can help me out?

I installed Node Red on a RPi3 (headless installation).
Working on a Mac and command line tool installing.

Thank you for your time!
Robert

Hi @Robert126 - welcome to the forum.

The Pi install script does not install node-red-admin (perhaps it should... @dceejay)

So you should first run:

sudo npm install -g node-red-admin

Then you should be able to run the node-red-admin hash-pw command.

Hi knolleary,

First of all thank you for your quick response!
If I do that I get the following:
pi@raspberrypi : ~ $ sudo npm install -g node-red-admin

[sudo] password for pi:

Despite all those warnings, it has actually installed.

You should now be able to run the node-red-admin command.

dceejay · 13 March 2020 22:05

Rather than add something we had to maintain just for that one command (it really bloated the dpkg install size) - I offered this PR a while back.. https://github.com/node-red/node-red/pull/1917

Robert126 · 13 March 2020 22:51

the node-red-admin hash-pw works now!
Thank you.

But when I they to create a password for an other user
node-red-john hash-pw
I get the following
pi@raspberrypi : / $ node-red-john hash-pw

-bash: node-red-john: command not found

I created the John user in the settings.js file

knolleary · 13 March 2020 22:54

The command is node-red-admin hash-pw regardless of the username.

Robert126 · 13 March 2020 23:02

Thank you. Sorry for my stupidity.

When I start node-red-start

I'm receiving the following error

The usually means you've missed off the comma , between functionGlobalContext and whatever setting is immediately before it.

Robert126 · 14 March 2020 09:53

Thank Knolleary for your help it is working!

Let's get started with Node Red
