1 00:00:00,510 --> 00:00:07,950 First of all, we will be launching one EC2 istance on AWS cloud that mean we will be launching our 2 00:00:07,950 --> 00:00:16,260 Web server on AWS cloud and then we will be installing the Apache Web server on that. 3 00:00:16,500 --> 00:00:19,080 And then we will see whether we are able to access. 4 00:00:19,090 --> 00:00:25,260 We are not going to cover just we will make one simple Web page and we will see whether we are able 5 00:00:25,260 --> 00:00:29,530 to access that Web site or not for practical purposes. 6 00:00:29,550 --> 00:00:30,920 We will be using AWS. 7 00:00:31,440 --> 00:00:32,280 EC2 8 00:00:32,640 --> 00:00:38,660 And you can get the AWS cloud free tier for one year. 9 00:00:39,000 --> 00:00:46,080 So we are assuming that you can create your free account on AWS type of thing. 10 00:00:46,890 --> 00:00:48,750 So here we will be looking at that. 11 00:00:49,320 --> 00:00:56,120 So first of all, what we will do, we will go into the AWS console, On AWS console. 12 00:00:56,140 --> 00:00:57,750 Lot of services are there. 13 00:00:58,050 --> 00:01:05,640 But what we are interested we are interested in this EC2, EC2 is used for creating virtual 14 00:01:05,640 --> 00:01:06,780 servers in the cloud. 15 00:01:07,000 --> 00:01:16,530 Or you can say that we can create virtual machines in the cloud, like for all the other labs. 16 00:01:16,530 --> 00:01:24,560 We created three VMS for the experimental purpose same way we can create the servers in the cloud. 17 00:01:24,930 --> 00:01:27,480 So for that we need EC2 service. 18 00:01:27,660 --> 00:01:30,870 So we will click on EC2 service. 19 00:01:31,710 --> 00:01:36,680 Then we will try to launch one instance how we are going to launch one instance. 20 00:01:37,020 --> 00:01:45,370 And please remember whenever you have to use AWS cloud, first of all, we need to create one key pair 21 00:01:45,750 --> 00:01:54,480 that public private key pair because whenever we are creating the VMS, we have to lock these VMS with our 22 00:01:55,590 --> 00:01:56,370 public key. 23 00:01:57,090 --> 00:02:02,010 Once we have locked our VMS with the public key, we can only open it with a private key. 24 00:02:02,280 --> 00:02:08,880 So we have to create the private key how we are going to create in our case, we have already created. 25 00:02:09,510 --> 00:02:15,660 If in your case it is not already created, then what you can do is create key pair. 26 00:02:16,110 --> 00:02:26,370 You can specify the name of the key and then you can download the key in PPK format or in PEM format. 27 00:02:26,880 --> 00:02:36,330 If you are downloaded in PEM format, then you need to convert that into PPK format by 28 00:02:36,330 --> 00:02:38,860 using some software like putty. 29 00:02:39,120 --> 00:02:41,760 But we have already done this thing. 30 00:02:42,300 --> 00:02:48,270 So Straightway, what we will do, we will go into our again EC2 dashboard. 31 00:02:48,870 --> 00:02:55,320 We will go to the instances, although in our case we have already launched that instance. 32 00:02:55,380 --> 00:02:59,490 I'm just going to tell you how we launched that instance. 33 00:03:00,060 --> 00:03:07,260 So whenever we are talking about the EC2 service, how to launch the instances, you have to say 34 00:03:07,440 --> 00:03:11,370 launch instance there, you will get this option. 35 00:03:11,580 --> 00:03:12,750 Launch instances. 36 00:03:14,620 --> 00:03:23,870 Now, a lot of choices are available, like Amazon linux2 AMI, MAC OS is there Redhat enterprise. 37 00:03:25,100 --> 00:03:28,050 So suse linux, Ubuntu, windows are there. 38 00:03:29,180 --> 00:03:30,420 Here we are going to choose. 39 00:03:30,430 --> 00:03:31,390 Amazon Linux. 40 00:03:31,390 --> 00:03:31,740 Why? 41 00:03:31,760 --> 00:03:38,280 Because it just behaves like the Centos7 that we have used in our other labs. 42 00:03:38,280 --> 00:03:44,800 So all the commands that we are comfortable there, they all will run in this Amazon Linux. 43 00:03:45,070 --> 00:03:50,170 And also other advantage is that it comes under free tier eligible. 44 00:03:50,590 --> 00:03:55,830 That mean when you're going to use it, there will be no charges for this operating system. 45 00:03:56,320 --> 00:04:00,000 So it is available for x86 architecture. 46 00:04:00,190 --> 00:04:07,380 And arm architecture also, but we are going to select 64 bit x86. 47 00:04:08,020 --> 00:04:09,790 So we are going to say select. 48 00:04:11,770 --> 00:04:19,860 Then you need to specify which processor you want to use, a lot of options are there in our case, 49 00:04:19,870 --> 00:04:28,010 we will keep it to t2.Micro, in which it is going to give us one virtual CPU, 1GB RAM although other 50 00:04:28,040 --> 00:04:28,420 you can also choose. 51 00:04:28,430 --> 00:04:35,790 like this is going to give you a 8 virtual cpu and 32GB RAM. 52 00:04:36,160 --> 00:04:41,200 But again, we want to keep our resources running under Free tier. 53 00:04:41,770 --> 00:04:44,950 So this comes under your free tier t2.micro. 54 00:04:45,310 --> 00:04:46,390 So we are going to choose. 55 00:04:46,900 --> 00:04:56,100 So we are going to say next configure detail, how many instances we just want one network subnet settings. 56 00:04:56,280 --> 00:05:02,050 OK, then what are you going to say add storage. 57 00:05:04,340 --> 00:05:10,250 Here, you can specify because by default, when you're going to launch a Linux machine cloud, 58 00:05:10,250 --> 00:05:15,950 it is going to give you 8GB, you can increase the size, but for this experiment, 8GB is more 59 00:05:15,950 --> 00:05:16,650 than sufficient. 60 00:05:16,940 --> 00:05:20,780 So we're going to keep as it and then add tag. 61 00:05:21,830 --> 00:05:22,550 What do you mean 62 00:05:22,550 --> 00:05:27,080 by tag like when we implement the physical servers, we name our servers. 63 00:05:27,260 --> 00:05:33,300 So some time in AWS, thousands of machine might be running. 64 00:05:33,320 --> 00:05:38,150 So we want to identify those machine so we can add the tag. 65 00:05:38,570 --> 00:05:44,510 How we can add the tag like name then we can specify. 66 00:05:47,330 --> 00:05:48,080 Apache. 67 00:05:50,050 --> 00:05:53,120 Server, anything you can specify. 68 00:05:55,980 --> 00:05:58,400 Then configure security group. 69 00:05:58,650 --> 00:06:05,610 Now, that is the most important thing in configures group mean by default when you are installing the 70 00:06:05,630 --> 00:06:09,960 Linux, it is automatically going to openssh port. 71 00:06:10,450 --> 00:06:16,750 But what other ports we need, we need because we have to implement HTTP servers. 72 00:06:16,950 --> 00:06:18,300 We need a http. 73 00:06:19,140 --> 00:06:24,660 So we are going to do http also then we will be doing https also. 74 00:06:27,460 --> 00:06:36,850 So it is opening 22, 80, and 43 ports, then review and lunch, and it is going to give you the 75 00:06:36,850 --> 00:06:38,830 information that everything is OK. 76 00:06:40,120 --> 00:06:49,360 You can double check all the things, then what you can say lunch, and then you have to select the 77 00:06:49,360 --> 00:06:51,790 key pair that you have already created. 78 00:06:52,030 --> 00:06:55,870 If you are not already created, what you can do, you can create it here. 79 00:06:56,440 --> 00:07:02,740 And then you have to acknowledge then you have to say launch instance, in every case we have already done 80 00:07:02,740 --> 00:07:04,980 this, then what we have to do. 81 00:07:05,290 --> 00:07:07,470 So in my case, I'm going to cancel it. 82 00:07:08,350 --> 00:07:14,200 So when we are going to lunch after two or three minutes, what it will show, it will show you the 83 00:07:14,200 --> 00:07:15,660 status that it is running. 84 00:07:16,330 --> 00:07:18,510 So then you are going to click it. 85 00:07:19,480 --> 00:07:22,800 Now you have to find out the details about this machine. 86 00:07:23,500 --> 00:07:30,820 The most important thing is because these all machines are given one private address, also public address 87 00:07:30,820 --> 00:07:31,180 also. 88 00:07:31,330 --> 00:07:37,120 So you have to note down this public address, once you have noted down this public address. 89 00:07:37,600 --> 00:07:43,300 Now, you need to connect with this instance which is running in this region ohio region. 90 00:07:43,900 --> 00:07:51,180 So you have to access it from the local machine because my local operating system is window. 91 00:07:51,400 --> 00:07:55,180 So what I have to do, I have to click on this. 92 00:07:55,180 --> 00:07:56,310 Putty tool is there. 93 00:07:57,040 --> 00:08:06,820 So here we are going to type the address, whatever addresses which has been allocated, then connection. 94 00:08:07,150 --> 00:08:14,050 Sometimes when there is inactivity for sometime, your connection with that machine will get lost. 95 00:08:14,350 --> 00:08:19,300 So you can specify this keepalive value what will happen. 96 00:08:19,960 --> 00:08:26,440 It will automatically keep on sending keepalive message that connection will not get terminated. 97 00:08:27,340 --> 00:08:34,660 Then you have to specify the data also, here by default, when you create that machine, one user 98 00:08:34,660 --> 00:08:38,740 get created the name of that user is EC2 user. 99 00:08:40,040 --> 00:08:52,700 then you have to specify your private key, in our case, the private key browse it is in some folder 100 00:08:52,700 --> 00:08:54,400 on desktop, vipin folder is there. 101 00:08:54,490 --> 00:09:01,840 So I am going to specify that now please remember when you are doing this, when we are going to say 102 00:09:01,840 --> 00:09:09,550 open the font size will be a little bit very small so you can go into the appearance and you can change 103 00:09:09,550 --> 00:09:10,270 the font. 104 00:09:11,830 --> 00:09:14,020 We are keeping a little bit larger font. 105 00:09:14,020 --> 00:09:18,880 So I'm saying, okay, then we are going to say open. 106 00:09:20,140 --> 00:09:23,050 Now what it will do, it will try to open. 107 00:09:23,680 --> 00:09:28,300 And if you are first time you are going to access this. 108 00:09:28,900 --> 00:09:34,720 So it will show you one message that whether it is safe to connect that machine. 109 00:09:34,720 --> 00:09:36,580 So there you are going to say yes. 110 00:09:37,300 --> 00:09:40,320 So by default, we are into which directory. 111 00:09:41,860 --> 00:09:44,200 Let us little bit change the color of this. 112 00:09:45,040 --> 00:09:55,060 So I will go into, we will see whether there are certain settings that change settings appearance. 113 00:09:56,470 --> 00:09:59,920 So color i just want to change. 114 00:10:02,130 --> 00:10:02,790 Colours. 115 00:10:05,440 --> 00:10:08,260 So we will see what colors. 116 00:10:11,970 --> 00:10:13,170 Default. 117 00:10:13,700 --> 00:10:22,580 OK, I'm keeping it default, but it need not changing, so we will see a later here how to change this. 118 00:10:23,070 --> 00:10:28,810 So here what we are doing where we are just running this pwd command. 119 00:10:29,110 --> 00:10:31,830 Now, we are log in as a EC2 user. 120 00:10:32,310 --> 00:10:40,110 So now what we would like we would like to log in as root user because Certain Command, you can do only 121 00:10:40,110 --> 00:10:44,500 with this as a root user so you can specify sudo -s. 122 00:10:45,210 --> 00:10:47,520 Now, we have logged in as a root user. 123 00:10:48,270 --> 00:10:56,870 So now the first thing is you have to install the software and for that you can use the yum install httpd 124 00:10:58,980 --> 00:11:04,590 like we did in our local machines same way, same command. 125 00:11:04,590 --> 00:11:04,970 will run. 126 00:11:06,180 --> 00:11:12,780 And then what you can do after that, we can verify with which command? 127 00:11:13,210 --> 00:11:14,940 rpm -q. 128 00:11:17,250 --> 00:11:24,210 And we can check the package, whether httpd packages there or not, in our case, it is 129 00:11:24,300 --> 00:11:25,300 already installed. 130 00:11:26,070 --> 00:11:36,030 So what we will do, we will go into /var/www/html directory, here. 131 00:11:36,030 --> 00:11:42,500 We are going to create one page, how we are going to create one page in this way. 132 00:11:44,690 --> 00:11:47,300 index.html. 133 00:11:49,290 --> 00:12:00,630 Then what we are going to say, we are going to type likethis thing Apache Web. 134 00:12:02,360 --> 00:12:06,140 Server, what you can specify. 135 00:12:08,460 --> 00:12:11,790 Running on. 136 00:12:14,620 --> 00:12:23,820 cloud you can specify, please remember, in our case, we are showing all these things, we have 137 00:12:23,820 --> 00:12:25,250 already created this thing. 138 00:12:25,560 --> 00:12:34,470 So these all slides are there whatever steps we are performing that mean this is the thing that how we 139 00:12:34,470 --> 00:12:34,830 did. 140 00:12:35,160 --> 00:12:36,600 launched instance. 141 00:12:36,960 --> 00:12:42,390 Then we selected the AMI then t2 tier, one instance. 142 00:12:43,230 --> 00:12:50,670 Then we selected that, you can say hard disk, then name Apache Web server, then we open 143 00:12:50,680 --> 00:12:50,910 those port. 144 00:12:50,910 --> 00:12:55,940 here we name our security group as Web server description Apache Web server. 145 00:12:57,030 --> 00:13:01,440 Then that was the review screen, then launch. 146 00:13:01,440 --> 00:13:03,390 We choose that,. 147 00:13:03,840 --> 00:13:08,760 We specify the key then this was when it was launching. 148 00:13:09,810 --> 00:13:14,040 Then it was showing one menu view instance, when we clicked on The View instances. 149 00:13:14,430 --> 00:13:17,370 What it was showing, it was showing this screen. 150 00:13:17,370 --> 00:13:29,310 So we noted down the address and that is we specify EC2 user, then that ip address 151 00:13:29,310 --> 00:13:30,570 port is 22. 152 00:13:31,650 --> 00:13:37,500 Then we change the font size to 18, then we specify the key. 153 00:13:38,020 --> 00:13:39,210 And this was the screen. 154 00:13:40,500 --> 00:13:50,040 And with sudo -s, we logged in as a root user then rpm query httpd, initially it was not installed, so 155 00:13:50,040 --> 00:13:55,160 we installed by yum -q install httpd in quite mode. 156 00:13:55,950 --> 00:13:57,210 So this was the screen. 157 00:13:57,540 --> 00:14:02,580 It installed certain dependent package also, and it was asking for the conformation. 158 00:14:02,580 --> 00:14:03,630 So we specified. 159 00:14:03,630 --> 00:14:11,960 Yes, like in the local lab we implemented, then we have going to into the /var/www/html directory and then we created 160 00:14:11,960 --> 00:14:14,730 the file Apache web server is running in cloud. 161 00:14:15,810 --> 00:14:20,730 So here also what we are trying to do again, we are saying. 162 00:14:22,900 --> 00:14:25,300 in. 163 00:14:26,560 --> 00:14:26,950 cloud. 164 00:14:28,650 --> 00:14:29,880 So we can save. 165 00:14:32,820 --> 00:14:38,430 Clear the screen, then which command you're going to run systemctl. 166 00:14:41,530 --> 00:14:48,270 restart httpd because here already . 167 00:14:49,030 --> 00:14:55,630 First it is running, so you have to restart in real what command you have to run. 168 00:14:57,100 --> 00:14:58,270 These are the command. 169 00:14:58,270 --> 00:15:06,150 We are going to run for temporary running httpd server, you have to run systemctl start httpd systemctl 170 00:15:06,150 --> 00:15:14,620 enable httpd, then we can verify it with the IP address, whether it is working properly 171 00:15:14,620 --> 00:15:15,010 or not. 172 00:15:15,640 --> 00:15:19,040 So we will go to the browser and specify this address. 173 00:15:19,480 --> 00:15:21,250 So let us go into the browser. 174 00:15:23,260 --> 00:15:26,980 So we are going to specify the address http:// 175 00:15:30,130 --> 00:15:38,890 the address of the virtual machine 52.15.85.. 176 00:15:41,030 --> 00:15:42,130 32. 177 00:15:44,610 --> 00:15:52,130 So this is a apache web server running in cloud that mean our Apache Web server is properly running. 178 00:15:55,020 --> 00:16:01,530 That was the verification, and if you want to change the configuration settings, please remember all 179 00:16:01,530 --> 00:16:13,890 the files are same like you can open with vi editor vi /etc/httpd/conf/httpd.conf. 180 00:16:16,990 --> 00:16:26,350 Same file are there, same thing we can configure in cloud like we did in so we will not be again repeating 181 00:16:26,350 --> 00:16:26,860 those things. 182 00:16:26,950 --> 00:16:30,790 We just wanted to show you how to launch one instance in cloud. 183 00:16:31,630 --> 00:16:38,650 So this is our instance properly working and we are able to access the page as we have shown. 184 00:16:39,100 --> 00:16:44,590 So both we have covered a little bit practical also, and we have shown you the slide. 185 00:16:44,590 --> 00:16:48,580 So very easy to launch in the cloud, your Web server.
