1 1 00:00:00,250 --> 00:00:01,860 Hi guys, and welcome back. 2 2 00:00:01,860 --> 00:00:03,330 In this section, we're going to be dealing with 3 3 00:00:03,330 --> 00:00:05,320 deployment in DigitalOcean. 4 4 00:00:05,320 --> 00:00:06,900 So we're gonna go through this video 5 5 00:00:06,900 --> 00:00:09,340 and create out first server. 6 6 00:00:09,340 --> 00:00:12,060 In DigitalOcean, you can click here at the top right 7 7 00:00:12,940 --> 00:00:15,300 and create a new Droplet. 8 8 00:00:15,300 --> 00:00:17,963 A Droplet in DigitalOcean is a server. 9 9 00:00:19,130 --> 00:00:21,300 Now that we're about to create our Droplet, 10 10 00:00:21,300 --> 00:00:23,350 there are a bunch of configuration options 11 11 00:00:23,350 --> 00:00:25,090 that we have to choose from, 12 12 00:00:25,090 --> 00:00:27,010 what operating system we want, 13 13 00:00:27,010 --> 00:00:31,290 and we're gonna go for Ubuntu 18.04. 14 14 00:00:31,290 --> 00:00:33,670 That's because version 18.04 of Ubuntu 15 15 00:00:33,670 --> 00:00:35,550 is a Long Term Support version, 16 16 00:00:35,550 --> 00:00:38,580 which means it's gonna be maintained for many years, 17 17 00:00:38,580 --> 00:00:40,950 so if there's any security updates or anything like that, 18 18 00:00:40,950 --> 00:00:45,430 18.04 will receive them up until 2022, I think. 19 19 00:00:45,430 --> 00:00:49,910 Okay, so 19.04, 19.10 are not Long Term Support versions, 20 20 00:00:49,910 --> 00:00:52,380 so I will use 18.04. 21 21 00:00:52,380 --> 00:00:53,980 If you want to use any other version 22 22 00:00:53,980 --> 00:00:56,090 of these operating systems like FreeBSD, 23 23 00:00:56,090 --> 00:00:58,070 Fedora, Debian, or CentOS, 24 24 00:00:58,070 --> 00:01:01,230 which we used in a past version of this course, 25 25 00:01:01,230 --> 00:01:02,580 then feel free to do that, 26 26 00:01:02,580 --> 00:01:04,980 but the instructions that we talk about in this section 27 27 00:01:04,980 --> 00:01:06,270 will not apply. 28 28 00:01:06,270 --> 00:01:08,620 So the instructions in these sections 29 29 00:01:08,620 --> 00:01:11,590 will only be for Ubuntu 18.04, 30 30 00:01:11,590 --> 00:01:13,950 not any of the other versions of Ubuntu 31 31 00:01:13,950 --> 00:01:16,010 and not any of the other operating systems, 32 32 00:01:16,010 --> 00:01:19,470 so you must use 18.04 to follow these videos. 33 33 00:01:19,470 --> 00:01:21,550 Then we have to choose what kind of computer we want 34 34 00:01:21,550 --> 00:01:23,700 running our code. 35 35 00:01:23,700 --> 00:01:27,020 I would go for a Standard Droplet, a standard server, 36 36 00:01:27,020 --> 00:01:28,870 and you can left here. 37 37 00:01:28,870 --> 00:01:33,870 You can click left there and go to the $5 a month server. 38 38 00:01:33,900 --> 00:01:35,657 You don't need anything more expensive. 39 39 00:01:35,657 --> 00:01:37,800 $5 a month is plenty for what we're doing here, 40 40 00:01:37,800 --> 00:01:40,150 and it's plenty to learn how to deploy 41 41 00:01:40,150 --> 00:01:41,750 your application to it. 42 42 00:01:41,750 --> 00:01:43,700 Later on, if you feel like you need more power, 43 43 00:01:43,700 --> 00:01:45,573 you can always go more expensive. 44 44 00:01:46,760 --> 00:01:48,360 You have the option to add backups, 45 45 00:01:48,360 --> 00:01:51,790 which I'm gonna say No because this is a learning server, 46 46 00:01:51,790 --> 00:01:55,430 but if you are having a database storage 47 47 00:01:55,430 --> 00:01:56,390 in your application 48 48 00:01:56,390 --> 00:01:58,090 and you wanna make sure you don't lose it, 49 49 00:01:58,090 --> 00:02:00,090 then I would enable backups. 50 50 00:02:00,090 --> 00:02:02,950 Block storage is not necessary until you have more servers 51 51 00:02:02,950 --> 00:02:04,700 and you wanna store files and things like that 52 52 00:02:04,700 --> 00:02:06,380 so I'm not gonna add block storage. 53 53 00:02:06,380 --> 00:02:07,990 Then you've got your datacenter region 54 54 00:02:07,990 --> 00:02:11,210 or where in the world you want your server to be, 55 55 00:02:11,210 --> 00:02:13,230 and you should select here 56 56 00:02:13,230 --> 00:02:16,650 the server that is closest to your users. 57 57 00:02:16,650 --> 00:02:18,900 So whoever is gonna be using the application, 58 58 00:02:18,900 --> 00:02:20,800 you want the server to be close to them 59 59 00:02:20,800 --> 00:02:22,200 so that they will be able 60 60 00:02:22,200 --> 00:02:23,970 to use your application very quickly 61 61 00:02:23,970 --> 00:02:26,300 and it won't take very long to load. 62 62 00:02:26,300 --> 00:02:28,410 In my case, most of my students are in the United States, 63 63 00:02:28,410 --> 00:02:30,880 so we're gonna go for here, San Francisco, 64 64 00:02:30,880 --> 00:02:32,710 or you can go New York if they are mostly 65 65 00:02:32,710 --> 00:02:34,880 in the New York coast. 66 66 00:02:34,880 --> 00:02:36,350 Next, we've got some additional options 67 67 00:02:36,350 --> 00:02:38,870 that we're not gonna select any of, 68 68 00:02:38,870 --> 00:02:40,370 and you've got your SSH keys 69 69 00:02:40,370 --> 00:02:43,040 if you want to add those for login. 70 70 00:02:43,040 --> 00:02:46,490 Now, we're gonna use a password to log into our server, 71 71 00:02:46,490 --> 00:02:48,960 so I'm not gonna add any of these SSH keys, 72 72 00:02:48,960 --> 00:02:51,520 but if you know what SSH keys are and you wanna use them, 73 73 00:02:51,520 --> 00:02:53,340 feel free to add it there. 74 74 00:02:53,340 --> 00:02:56,140 Then, if you do that, you will not get a password. 75 75 00:02:56,140 --> 00:02:57,830 Instead, you'll be able to log in 76 76 00:02:57,830 --> 00:03:00,670 with a computer that has that SSH key. 77 77 00:03:00,670 --> 00:03:03,770 At the end, you can see How many Droplets? 78 78 00:03:03,770 --> 00:03:05,440 That means you can create multiple Droplets 79 79 00:03:05,440 --> 00:03:07,410 with the same configuration if that's what you wanna do, 80 80 00:03:07,410 --> 00:03:09,560 if you want multiple of them that are the same, 81 81 00:03:09,560 --> 00:03:11,380 and you can also give it a name, 82 82 00:03:11,380 --> 00:03:15,480 and here, we're gonna type deployment-learning-droplet. 83 83 00:03:15,480 --> 00:03:18,090 If you're using projects, which I am, 84 84 00:03:18,090 --> 00:03:20,650 just to organise your Droplets into different ones, 85 85 00:03:20,650 --> 00:03:22,910 you can also select your project down here, 86 86 00:03:22,910 --> 00:03:24,900 and you can also add tags to your Droplets 87 87 00:03:24,900 --> 00:03:25,860 in case you have a lot of them, 88 88 00:03:25,860 --> 00:03:27,570 and you wanna be able to search through them 89 89 00:03:27,570 --> 00:03:28,780 a bit more effectively, 90 90 00:03:28,780 --> 00:03:31,350 but for now, we don't really need them. 91 91 00:03:31,350 --> 00:03:32,183 That's it. 92 92 00:03:32,183 --> 00:03:34,050 Once you do that, you can press Create, 93 93 00:03:34,050 --> 00:03:36,040 and as soon as a Droplet is created, 94 94 00:03:36,040 --> 00:03:39,940 DigitalOcean will start charging you for every minute 95 95 00:03:39,940 --> 00:03:42,230 that the Droplet is live. 96 96 00:03:42,230 --> 00:03:45,630 So do remember that if you do delete this Droplet, 97 97 00:03:45,630 --> 00:03:48,550 you will only get charged for the amount of hours or minutes 98 98 00:03:48,550 --> 00:03:50,530 that this Droplet has been alive. 99 99 00:03:50,530 --> 00:03:52,047 So you're not gonna get charged 100 100 00:03:52,047 --> 00:03:53,780 $5 immediately at the beginning. 101 101 00:03:53,780 --> 00:03:55,350 If you delete this just now, 102 102 00:03:55,350 --> 00:03:57,450 you'll only get charged a couple of cents. 103 103 00:03:58,670 --> 00:04:00,280 So you can always recreate your Droplets 104 104 00:04:00,280 --> 00:04:02,093 up until you've run out of credit, 105 105 00:04:03,100 --> 00:04:03,933 and there you have it. 106 106 00:04:03,933 --> 00:04:05,150 That is our Droplet. 107 107 00:04:05,150 --> 00:04:08,530 You've got some IP address that you can use 108 108 00:04:08,530 --> 00:04:10,080 to access your Droplet, 109 109 00:04:10,080 --> 00:04:13,160 and you've got a bunch of information on the Droplet itself, 110 110 00:04:13,160 --> 00:04:16,560 and that will be populated as you use it. 111 111 00:04:16,560 --> 00:04:18,790 So when we wanna log into our Droplet, 112 112 00:04:18,790 --> 00:04:20,990 just copy this IP address 113 113 00:04:20,990 --> 00:04:23,650 and log into it via SSH. 114 114 00:04:23,650 --> 00:04:24,483 What's gonna happen is 115 115 00:04:24,483 --> 00:04:27,520 you're gonna get an email with your password, 116 116 00:04:27,520 --> 00:04:31,050 and so, you can SSH into the Droplet using the password 117 117 00:04:31,050 --> 00:04:32,650 that you got on your email, 118 118 00:04:32,650 --> 00:04:35,800 and you'll be able to log in and change your password there. 119 119 00:04:35,800 --> 00:04:38,790 Alternatively, you can also log in using the Console here 120 120 00:04:38,790 --> 00:04:41,860 up on DigitalOcean by clicking this Console button. 121 121 00:04:41,860 --> 00:04:45,360 However, I found this to be not great, 122 122 00:04:45,360 --> 00:04:47,910 so I will not use this thing here. 123 123 00:04:47,910 --> 00:04:51,220 Instead, I will go over to my Terminal. 124 124 00:04:51,220 --> 00:04:54,740 I've opened my Terminal app here on Mac, 125 125 00:04:54,740 --> 00:04:57,570 and all you have to do if you're using Mac or Linux 126 126 00:04:57,570 --> 00:05:02,500 is type ssh root@ your server's IP address, 127 127 00:05:02,500 --> 00:05:05,270 and then, enter the password. 128 128 00:05:05,270 --> 00:05:06,570 I have to type yes to this, 129 129 00:05:06,570 --> 00:05:08,280 but maybe you won't have to do that. 130 130 00:05:08,280 --> 00:05:10,910 Then enter your password to your root account 131 131 00:05:10,910 --> 00:05:12,360 that you've got on your email. 132 132 00:05:12,360 --> 00:05:14,400 If you're using Windows, 133 133 00:05:14,400 --> 00:05:17,780 then you may not be able to use SSH from your Terminal, 134 134 00:05:17,780 --> 00:05:20,350 which is called cmd.exe. 135 135 00:05:20,350 --> 00:05:22,130 On Windows, you may have to do download 136 136 00:05:22,130 --> 00:05:23,570 an alternative software, 137 137 00:05:23,570 --> 00:05:27,410 and I recommend one called PuTTY for Windows. 138 138 00:05:27,410 --> 00:05:28,350 Once you've logged in, 139 139 00:05:28,350 --> 00:05:31,020 the server will ask you to change the root password, 140 140 00:05:31,020 --> 00:05:32,930 so do that and change it to something 141 141 00:05:32,930 --> 00:05:34,220 that you can remember, 142 142 00:05:34,220 --> 00:05:36,030 and then, we can go into the server 143 143 00:05:36,030 --> 00:05:38,410 and start making some changes. 144 144 00:05:38,410 --> 00:05:39,960 I'll see you in the next video.
