I in this lecture show you how to install no grid on your Raspberry Pi to do that, I'll be following
the instructions from the documentation and the documentation getting started, Raspberry Pi.
And I'm just going to follow this script here so you can see it's very easy.
So the first thing to do is to follow this structure, to issue this command here in order to ensure
that, as you can see here, the OPM is able to build any binary modules that it needs.
So I'm going to do this first and then I'm going to run this back command.
All right.
So let's go ahead.
I'm going to log in to my Raspberry Pi.
OK, and then I'm going to copy.
His command.
And pasted into my respray point.
Yes, sir, as you can see, there was a update to several get related packages, so as a good thing
that we are doing this now.
OK, and let's now install.
No dread itself or actually upgraded from the existing version that that comes with a Raspberry Pi is
this copy the command, the best command and pasted into my Raspberry Pi.
Yes, please.
All right, so it's going to take a while.
I'm going to fast forward at this point and continue once we're back.
And we're back, so Noad version twelve point eighteen point two with NPN six point fourteen point six
is installed as well as a note read call vision one point one point one.
We can actually start to read now and check it out.
So we're going to do this by running notarised locally.
And this is a command node rate PI and because I'm running node red on an old Raspberry Pi two with
limited memory and what I'm going to use this switch here all to space in order for it, in order full
node rate, I should say, to release any unused memory quickly rather than holding it.
So I'm just going to copy this command and paste it into my Raspberry Pi.
Get a few seconds for us to begin, for no to begin and.
OK, here we are.
It's up and running at this location and this port, so I'm going to open up a new tab and instead of
going for the IP address of the local host, I will say, hey, Tupi node red.
Local, which is a host name of my Raspberry Pi two and the Port one eight eight zero eight.
And there's my node red.
It's a fresh installation, OK?
That's one way to do it.
I prefer, however, to run, not replace our service.
So I'm going to take control, see to exit a. red and back in the documentation can see that there is
the option to run as a service and are the various commands to do so, such as to start, Strawbridge
started, etc..
No red already exists.
So for example.
I can say no right to start.
Which is what I did earlier, actually, and it will start like this, it's running as a service, going
to hit control, see to get out of it.
I want to be able to get no DRE to start automatically on boots.
I don't have to log on to my Raspberry Pi with SFH and manually started.
So I'm going to install a system D service for Node Red.
And to do that, I need to copy this command in to copy that in here.
So now I've got a link so that on bood this instruction is called, and if I want to disable that,
I would do this, I would say disable no direct service.
So if I restart my Raspberry Pi, actually, I'm going to do that now to test that.
No trick will be starting.
So let's try this out.
I'm going to say pseudo reboot.
OK, and then to refresh, we can see connection most this the Raspberry Pi is rebooting, going to
wait for the Raspberry Pi to continue booting up and then do refresh on this page.
Now.
Not yet.
And one more time.
Maker.
So my service now is operating perfect.
So now we have a working updated copy of Note Read on my Raspberry Pi to the next thing that I want
to show you in the next lecture are some configuration options.
No dread does have a configuration file and you can use it to tweak the set up of your note rate installation.
So let's check that out next.
