1 00:00:00,690 --> 00:00:06,960 I in this lecture show you how to install no grid on your Raspberry Pi to do that, I'll be following 2 00:00:06,960 --> 00:00:12,330 the instructions from the documentation and the documentation getting started, Raspberry Pi. 3 00:00:12,370 --> 00:00:16,660 And I'm just going to follow this script here so you can see it's very easy. 4 00:00:17,220 --> 00:00:25,110 So the first thing to do is to follow this structure, to issue this command here in order to ensure 5 00:00:25,110 --> 00:00:30,270 that, as you can see here, the OPM is able to build any binary modules that it needs. 6 00:00:30,690 --> 00:00:36,360 So I'm going to do this first and then I'm going to run this back command. 7 00:00:37,440 --> 00:00:37,830 All right. 8 00:00:37,830 --> 00:00:38,950 So let's go ahead. 9 00:00:39,000 --> 00:00:43,230 I'm going to log in to my Raspberry Pi. 10 00:00:52,710 --> 00:00:55,470 OK, and then I'm going to copy. 11 00:00:56,500 --> 00:00:57,250 His command. 12 00:00:58,650 --> 00:01:01,380 And pasted into my respray point. 13 00:01:15,430 --> 00:01:21,610 Yes, sir, as you can see, there was a update to several get related packages, so as a good thing 14 00:01:21,610 --> 00:01:22,600 that we are doing this now. 15 00:01:28,830 --> 00:01:32,700 OK, and let's now install. 16 00:01:34,180 --> 00:01:41,520 No dread itself or actually upgraded from the existing version that that comes with a Raspberry Pi is 17 00:01:41,660 --> 00:01:44,980 this copy the command, the best command and pasted into my Raspberry Pi. 18 00:01:49,290 --> 00:01:50,160 Yes, please. 19 00:01:51,060 --> 00:01:53,150 All right, so it's going to take a while. 20 00:01:53,250 --> 00:01:59,250 I'm going to fast forward at this point and continue once we're back. 21 00:02:09,840 --> 00:02:18,930 And we're back, so Noad version twelve point eighteen point two with NPN six point fourteen point six 22 00:02:18,930 --> 00:02:24,630 is installed as well as a note read call vision one point one point one. 23 00:02:25,200 --> 00:02:29,250 We can actually start to read now and check it out. 24 00:02:29,550 --> 00:02:33,630 So we're going to do this by running notarised locally. 25 00:02:33,630 --> 00:02:42,240 And this is a command node rate PI and because I'm running node red on an old Raspberry Pi two with 26 00:02:42,240 --> 00:02:48,920 limited memory and what I'm going to use this switch here all to space in order for it, in order full 27 00:02:48,930 --> 00:02:54,320 node rate, I should say, to release any unused memory quickly rather than holding it. 28 00:02:54,690 --> 00:03:00,180 So I'm just going to copy this command and paste it into my Raspberry Pi. 29 00:03:03,170 --> 00:03:08,360 Get a few seconds for us to begin, for no to begin and. 30 00:03:10,880 --> 00:03:11,790 OK, here we are. 31 00:03:11,810 --> 00:03:19,640 It's up and running at this location and this port, so I'm going to open up a new tab and instead of 32 00:03:19,640 --> 00:03:29,240 going for the IP address of the local host, I will say, hey, Tupi node red. 33 00:03:31,060 --> 00:03:39,040 Local, which is a host name of my Raspberry Pi two and the Port one eight eight zero eight. 34 00:03:39,770 --> 00:03:42,170 And there's my node red. 35 00:03:43,790 --> 00:03:46,360 It's a fresh installation, OK? 36 00:03:46,730 --> 00:03:47,870 That's one way to do it. 37 00:03:48,410 --> 00:03:51,420 I prefer, however, to run, not replace our service. 38 00:03:51,420 --> 00:04:01,370 So I'm going to take control, see to exit a. red and back in the documentation can see that there is 39 00:04:01,370 --> 00:04:10,640 the option to run as a service and are the various commands to do so, such as to start, Strawbridge 40 00:04:10,640 --> 00:04:11,480 started, etc.. 41 00:04:11,960 --> 00:04:13,650 No red already exists. 42 00:04:13,650 --> 00:04:14,720 So for example. 43 00:04:16,970 --> 00:04:20,180 I can say no right to start. 44 00:04:22,850 --> 00:04:29,510 Which is what I did earlier, actually, and it will start like this, it's running as a service, going 45 00:04:29,510 --> 00:04:31,830 to hit control, see to get out of it. 46 00:04:32,480 --> 00:04:37,430 I want to be able to get no DRE to start automatically on boots. 47 00:04:37,480 --> 00:04:42,800 I don't have to log on to my Raspberry Pi with SFH and manually started. 48 00:04:43,190 --> 00:04:48,800 So I'm going to install a system D service for Node Red. 49 00:04:49,130 --> 00:04:56,140 And to do that, I need to copy this command in to copy that in here. 50 00:04:57,600 --> 00:05:07,680 So now I've got a link so that on bood this instruction is called, and if I want to disable that, 51 00:05:07,680 --> 00:05:11,600 I would do this, I would say disable no direct service. 52 00:05:11,940 --> 00:05:16,830 So if I restart my Raspberry Pi, actually, I'm going to do that now to test that. 53 00:05:17,610 --> 00:05:19,050 No trick will be starting. 54 00:05:19,060 --> 00:05:20,220 So let's try this out. 55 00:05:20,220 --> 00:05:23,310 I'm going to say pseudo reboot. 56 00:05:25,600 --> 00:05:34,450 OK, and then to refresh, we can see connection most this the Raspberry Pi is rebooting, going to 57 00:05:34,450 --> 00:05:40,030 wait for the Raspberry Pi to continue booting up and then do refresh on this page. 58 00:05:43,600 --> 00:05:43,930 Now. 59 00:05:45,060 --> 00:05:45,660 Not yet. 60 00:05:48,780 --> 00:05:49,920 And one more time. 61 00:05:50,980 --> 00:05:51,420 Maker. 62 00:05:52,180 --> 00:05:56,170 So my service now is operating perfect. 63 00:05:57,150 --> 00:06:04,810 So now we have a working updated copy of Note Read on my Raspberry Pi to the next thing that I want 64 00:06:04,810 --> 00:06:08,560 to show you in the next lecture are some configuration options. 65 00:06:08,830 --> 00:06:15,860 No dread does have a configuration file and you can use it to tweak the set up of your note rate installation. 66 00:06:15,880 --> 00:06:17,680 So let's check that out next.
