WEBVTT 00:04.530 --> 00:07.910 No usual tale thrills to Jawa up and running on your computer. 00:08.220 --> 00:14.510 And the second, you should have downloaded the Kafka archive and unzip it into a specific folder. 00:14.850 --> 00:17.840 In my case, I have created the folder called Kafka. 00:17.850 --> 00:24.420 And if I lose the contents of this folder, I see a file folder called Being Leaside Dogs Config and 00:24.420 --> 00:28.050 Logs and two text files, license and naughties. 00:28.530 --> 00:32.370 Let's have a look at the contents of Benfold up a glass bin. 00:33.120 --> 00:40.170 And in this folder you'll find a bunch of the files with Extension's Dot S.H. Also you will find here 00:40.170 --> 00:41.490 Subfolder Windows. 00:41.640 --> 00:50.580 And if I list contents of Windows folder, I see a bunch of bad files and basically every file here 00:50.580 --> 00:58.680 in Windows folder or directly in front of a beautiful door is executable script, executable file and 00:58.680 --> 01:06.960 files with extension dot as executable files for Unix like systems like Micheal's and so on, and the 01:06.960 --> 01:11.100 files in Windows folder files executable on the windows. 01:11.610 --> 01:18.780 And basically in order to run specific service of Kafka, you should launch specific script, nothing 01:18.780 --> 01:19.110 else. 01:19.590 --> 01:20.430 Pretty simple. 01:20.910 --> 01:26.060 And also you are able to run every script multiple times as well. 01:26.370 --> 01:33.190 And that means that you are able to start, for example, multiple Kafka brockers on a single computer. 01:33.390 --> 01:35.070 We will try that, of course, later on. 01:35.700 --> 01:41.520 But for now, please understand that the installation of Kafka is simply a set of executable files, 01:41.540 --> 01:42.270 nothing else. 01:42.970 --> 01:47.590 OK, let's clear Tamino and let's again have a look at the contents of this folder. 01:47.910 --> 01:50.060 There is also a folder called Gongfu. 01:50.400 --> 01:52.020 Let's examine the files there. 01:52.710 --> 01:57.090 And here you'll find the files with extension DOT properties. 01:57.450 --> 02:04.800 And those files contain actually default configurations for specific services that can be started using 02:04.800 --> 02:05.930 executable files. 02:06.300 --> 02:12.220 For example, this file zookeeper's, the properties is used in order to launch zookeeper's service. 02:12.810 --> 02:17.100 This file produced a lot of properties, is used in order to start producer. 02:17.520 --> 02:25.320 This one is used in order to start Kafka, Sarah or Kafka program and so on inside of the Sidewalks 02:25.320 --> 02:25.820 folder. 02:25.830 --> 02:26.730 Let's have a look at it. 02:27.510 --> 02:35.610 You'll find archive extension Zebb Gold Side Docs and you are able to extract this archive and it will 02:35.610 --> 02:41.190 basically contain documentation of a specific version of Kafka that is installed in your computer. 02:41.700 --> 02:43.680 Also, there is a folder called Logs. 02:43.950 --> 02:44.840 Let's have a look at it. 02:45.330 --> 02:46.380 Sorry, logs. 02:46.680 --> 02:53.970 And this folder contains log files that are related to services that are started using a different executable 02:53.970 --> 02:54.480 files. 02:54.810 --> 03:01.040 For example, here you'll see log file that relates to start of the Cafcass Sarah Kafka Brolga. 03:01.470 --> 03:06.860 You can also read any file in any of those folders, a terminal and here in time. 03:06.870 --> 03:10.470 No, you are able to use, for example, curcumin and lists. 03:10.470 --> 03:14.880 For example, read file config, Sarah Dot properties. 03:15.090 --> 03:17.670 It is configuration file for Kafka Breuker. 03:18.090 --> 03:24.540 And if I press enter, you'll see a file that basically contains a set of default configuration parameters 03:24.690 --> 03:31.530 like log segment by its local advance and check intervale, dot, mouse and so on, simply set of default 03:31.530 --> 03:33.390 parameters for several start. 03:33.780 --> 03:36.570 Let's also have a look at one of the files and Benfold. 03:36.930 --> 03:42.600 And at any moment of time you're able to press step in order to see all options available here at this 03:42.600 --> 03:42.940 line. 03:43.080 --> 03:43.890 Let's step. 03:44.190 --> 03:48.740 And for example, let's have a look at the contents of zookeeper's shell. 03:49.070 --> 03:56.220 S.H., you can start typing in next Aldabra step in order to autocomplete and the Helix type shall not. 03:56.220 --> 04:04.650 S.H. And here you'll find executable file for Unix like systems and every file with extension dot as 04:04.650 --> 04:05.070 age. 04:05.070 --> 04:06.510 Start with this line. 04:06.540 --> 04:09.900 It is actually common, that old line of the Shell script. 04:10.290 --> 04:17.340 And this line indicates which program on Unix like computer should be used in order to execute this 04:17.340 --> 04:17.790 file. 04:18.000 --> 04:24.780 And I have told you that this script is actually a shell script and this white S.H. program located 04:24.780 --> 04:29.910 in Benfold should be used in order to execute this file below. 04:29.910 --> 04:36.060 You'll see a bunch of comments and after comments you'll see basically body of this shell script and 04:36.060 --> 04:37.590 hear those lines do some job. 04:37.800 --> 04:43.650 But let me clear time and show you the location of each application itself in order to find it. 04:43.650 --> 04:45.390 Let me see to use our folder. 04:45.540 --> 04:48.860 And here said to be in the folder. 04:48.990 --> 04:52.680 It will be system folder and the left list files here. 04:52.860 --> 04:56.610 And you'll find here, for example, file Golden Age. 04:56.820 --> 05:00.300 And that's exactly the application that is used for execution of. 05:00.470 --> 05:08.780 Executable files also you'll find here a bunch of other files like and we are and so on, for example, 05:08.780 --> 05:11.630 this one is used to create new folder on the computer. 05:11.900 --> 05:19.580 This one else was just used, OK, this where the application is actually located on Unix like systems. 05:19.940 --> 05:23.990 OK, let's go back to Kafka, Sedin COFCO Clear. 05:24.230 --> 05:30.950 And also let me show you how to read files in a more convenient way, because basically reading text 05:30.950 --> 05:33.590 files in the terminal is not the best way to do that. 05:33.890 --> 05:39.000 But if we will talk about editing using terminal, it is also a nightmare. 05:39.270 --> 05:45.410 So the next Lúcio, I'll quickly show you how to install open source text editor called Visual Studio 05:45.410 --> 05:45.740 Code. 05:45.890 --> 05:51.410 And I will show you how to open the contents of this folder there and read different files there and 05:51.410 --> 05:52.390 also added them. 05:52.760 --> 05:54.350 I'll see you in the next one by.
