WEBVTT 00:00.200 --> 00:00.730 Heroine. 00:00.740 --> 00:01.610 And welcome back. 00:01.610 --> 00:07.370 So now that we have our server up and running, the next important and the exciting practical that we'll 00:07.370 --> 00:10.340 be doing is the installation part of Nginx. 00:10.340 --> 00:11.900 So let's get started. 00:11.900 --> 00:14.720 So installing Nginx is very straightforward. 00:14.720 --> 00:20.000 So there are multiple public repositories that are available and you can directly go ahead and install 00:20.000 --> 00:20.810 nginx from them. 00:20.810 --> 00:27.470 So let's assume that you have a specific repository and this repository has the nginx RPM that is available. 00:27.470 --> 00:33.380 So all you need to do is you have to do a Yum install nginx and the Nginx will be installed within your 00:33.380 --> 00:34.310 Linux server. 00:34.310 --> 00:36.530 So this is the high level overview. 00:36.530 --> 00:38.270 So let's quickly try it out. 00:38.270 --> 00:40.370 So I'm connected to a demo server. 00:40.370 --> 00:42.980 So the installation of Nginx is very simple. 00:42.980 --> 00:49.310 All you need to do is you'll have to specify yum, install nginx and it is asking for confirmation. 00:49.310 --> 00:56.090 So let's do a Y to confirm the installation process and that's about it. 00:56.090 --> 01:02.850 So if you quickly want to verify if Nginx is up and running, you can specify systemctl status nginx. 01:03.240 --> 01:11.220 So currently it is showing Nginx is inactive so you can manually start it so you can run systemctl start 01:11.220 --> 01:14.730 nginx and let's quickly verify yet again. 01:14.730 --> 01:18.990 And now you see our nginx is up and running now from the web browser. 01:18.990 --> 01:24.690 Let's also verify if our default nginx page is loading, so I'll copy the public IP of the server and 01:24.690 --> 01:25.800 let's press enter. 01:25.800 --> 01:31.650 Now, if everything is working fine you should see the default nginx page to be up and running over 01:31.650 --> 01:32.070 here. 01:32.070 --> 01:38.010 Now, one important part to note here is that the rock Linux that we are using, it already has one 01:38.010 --> 01:42.930 of the repositories available from which this nginx rpm is being fetched. 01:42.960 --> 01:44.640 Now let me quickly show you. 01:44.640 --> 01:48.270 So if you would have gone a bit up over here. 01:48.300 --> 01:54.690 Here you see the Nginx package is coming from a repository called as Appstream over here. 01:54.690 --> 01:58.740 Now as we are discussing, there are other repositories available as well. 01:58.740 --> 02:04.320 So if you would quickly look into the official website, they have their own set of repositories. 02:04.320 --> 02:06.870 So basically let me quickly show you. 02:06.870 --> 02:12.420 So you have a CentOS repository and if you go a bit down, you also have a Debian Ubuntu repository 02:12.420 --> 02:13.020 over here. 02:13.020 --> 02:16.470 So let's explore the Nginx repository. 02:16.470 --> 02:19.500 So you have version five, version six, version seven and version eight. 02:19.500 --> 02:21.990 So these are basically the CentOS version. 02:22.110 --> 02:29.700 And within here under the RPMs you see you have the RPMs related to the Nginx version. 02:29.700 --> 02:35.760 So you can also if you would want a specific version of Nginx for your environment, you can also use 02:35.760 --> 02:37.050 this specific approach. 02:37.050 --> 02:40.950 Now, the easiest way to do that now let me also show you this. 02:40.950 --> 02:46.020 So currently if I do a nginx hyphen v it shows me a specific version of Nginx. 02:46.020 --> 02:49.620 In this case it is version one point 14.1. 02:49.650 --> 02:55.680 However, if you would like the latest version that was released by Nginx, you can also explore the 02:55.680 --> 03:01.560 Nginx repository which have been officially provided because this is where the latest version usually 03:01.560 --> 03:02.550 comes first. 03:02.550 --> 03:08.130 And from here you can also go ahead and fetch the link of the latest RPM. 03:08.130 --> 03:09.450 Let's copy this up. 03:09.480 --> 03:12.480 You can download that RPM within the server. 03:12.480 --> 03:14.040 So let's do a wget. 03:14.070 --> 03:15.900 Let me paste the RPM here. 03:15.900 --> 03:21.510 So currently the wget command is not found, so let's also go ahead and install wget. 03:22.140 --> 03:24.960 All right, let's download this RPM. 03:26.430 --> 03:27.500 So if I do. 03:27.510 --> 03:34.050 LS so this is the nginx RPM and you can also directly install from this specific nginx rpm. 03:34.050 --> 03:37.920 Let me also show you this so that we have a better clarity here. 03:37.920 --> 03:42.900 So first let's go ahead and remove the nginx that we have installed. 03:47.070 --> 03:47.680 All right. 03:47.680 --> 03:53.310 So we have removed the links and we'll be installing through this specific RPM file. 03:53.320 --> 03:56.740 So I'll specify yum install this time. 03:56.740 --> 04:03.670 You can specify the name of the RPM file here and this time the repository you see it is showing command 04:03.670 --> 04:03.940 line. 04:03.940 --> 04:09.700 I'll specify why and great our nginx is installed. 04:10.630 --> 04:17.200 So if you specify systemctl status nginx it currently is showing inactive or dead. 04:17.200 --> 04:25.960 So let's quickly start our nginx here and let's also do a systemctl enable nginx to ensure that the 04:25.960 --> 04:29.350 nginx automatically starts if we restart the server. 04:29.470 --> 04:36.010 And here if you do a nginx hyphen v you should see that this is a newer version of Nginx which is one 04:36.010 --> 04:37.930 point 20.1. 04:37.930 --> 04:44.680 So now let's also try and refresh this page here and you should see now we have a different default 04:44.680 --> 04:46.700 Nginx page that is available. 04:46.700 --> 04:50.240 So depending upon your choice you can use any one of the methods. 04:50.240 --> 04:55.580 The simplest one, as we were discussing, is you directly run the Yum install nginx command to install 04:55.580 --> 04:56.420 the nginx. 04:56.420 --> 05:01.370 However, for production environments in your organization there is a requirement and there should be 05:01.370 --> 05:06.890 a requirement that all of the servers should use the exact version of Nginx. 05:06.890 --> 05:14.180 So you can download this specific RPM file, you can store it in your organization repository and whenever 05:14.180 --> 05:19.040 you go ahead and do a Yum install, it will only use this specific version. 05:19.040 --> 05:23.810 So multiple approaches depending upon the use cases from your side. 05:23.810 --> 05:25.910 So that's the high level overview. 05:25.910 --> 05:28.130 And with this, we'll conclude today's video.
