1
00:00:00,620 --> 00:00:01,450
Hey, folks.

2
00:00:01,460 --> 00:00:04,540
So this is the last step of our lab setup.

3
00:00:04,550 --> 00:00:07,310
We have downloaded and install Oracle Virtual Box.

4
00:00:07,310 --> 00:00:10,480
Then we have downloaded and installed Linux operating system.

5
00:00:10,490 --> 00:00:17,030
Now it's time to install Ansible software or Ansible engine on our Linux operating system.

6
00:00:17,390 --> 00:00:17,810
All right.

7
00:00:17,810 --> 00:00:24,170
So one important thing before you go ahead and install Ansible is that I want you to take a VM snapshot.

8
00:00:24,260 --> 00:00:31,530
This will allow you to come back or revert back to the VM original state when you took the snapshot.

9
00:00:31,550 --> 00:00:38,450
In case you do make a mistake or do some kind of misconfiguration on your Linux operating system.

10
00:00:38,720 --> 00:00:41,750
All right, so go to our Oracle VirtualBox.

11
00:00:44,230 --> 00:00:45,040
Right here.

12
00:00:45,040 --> 00:00:47,680
Your Ansible control node is powered off.

13
00:00:47,860 --> 00:00:49,330
You have this menu.

14
00:00:49,330 --> 00:00:54,790
If you don't have this menu, simply click on these three dots, click on Snapshot and then click Take.

15
00:00:55,090 --> 00:00:56,110
Give it a name.

16
00:00:56,380 --> 00:01:03,670
I'm going to give Linux install point which will remind me this is the time when I've completed the

17
00:01:03,670 --> 00:01:04,840
Linux installation click.

18
00:01:04,840 --> 00:01:05,410
Okay.

19
00:01:06,100 --> 00:01:08,410
All right, it's done and I'll go ahead and click Start.

20
00:01:17,260 --> 00:01:17,650
All right.

21
00:01:17,650 --> 00:01:24,310
While this virtual machine or this Linux operating system is starting it up, let's go to the next step,

22
00:01:24,310 --> 00:01:28,540
which is Ansible installation guide can be found on this link.

23
00:01:28,540 --> 00:01:34,600
So I want you to write down this link because this will give you a lot of good information of step by

24
00:01:34,600 --> 00:01:37,990
step instruction on installing Ansible.

25
00:01:37,990 --> 00:01:44,440
If you are installing a different version, then sent us eight, which I am going to be installing it

26
00:01:44,440 --> 00:01:45,010
on.

27
00:01:45,340 --> 00:01:54,190
So if I go to my Firefox, which I have already opened and I am already on that page, on this page

28
00:01:54,190 --> 00:02:01,270
you will notice here's a list of all the instructions of installing Ansible on different operating system.

29
00:02:01,470 --> 00:02:04,240
Right here is RHEL Center or Fedora.

30
00:02:04,240 --> 00:02:10,570
These are the instructions which we will follow to install it on CentOS.

31
00:02:10,570 --> 00:02:16,570
If you are doing it on a button to follow this instruction for Dave and follow this instruction and

32
00:02:16,570 --> 00:02:17,830
there are other.

33
00:02:18,950 --> 00:02:26,060
Unix or Linux type operating system, which you could follow the instruction and install Ansible.

34
00:02:26,780 --> 00:02:27,320
All right.

35
00:02:27,440 --> 00:02:32,120
Going back to our slide and going back to our virtual machine.

36
00:02:32,300 --> 00:02:34,760
Our virtual machine is up.

37
00:02:36,240 --> 00:02:38,640
And let's log in as our self.

38
00:02:44,840 --> 00:02:45,140
Okay.

39
00:02:45,140 --> 00:02:48,770
So if you notice, this is a smaller windows of a virtual box.

40
00:02:48,770 --> 00:02:53,690
If you want to make this window bigger, you could right click on your desktop, go to display setting.

41
00:02:56,260 --> 00:02:58,630
And right here where you see resolution.

42
00:02:59,490 --> 00:03:00,240
Click on it.

43
00:03:01,400 --> 00:03:07,060
Change the resolution to whichever resolution according to your requirement.

44
00:03:07,070 --> 00:03:09,500
I'm going to leave it as is for now.

45
00:03:10,890 --> 00:03:15,810
This is a welcome message that you're going to get every time you start it up.

46
00:03:15,810 --> 00:03:18,840
You could actually quit out of it by clicking here and quit.

47
00:03:19,620 --> 00:03:19,950
All right.

48
00:03:19,950 --> 00:03:22,590
So going back to display will change whatever you have.

49
00:03:22,590 --> 00:03:24,660
Apply the setting and it will make it bigger.

50
00:03:24,660 --> 00:03:25,920
All right, click on activities.

51
00:03:26,580 --> 00:03:28,080
Go to the terminal.

52
00:03:28,380 --> 00:03:30,100
So you have the terminal open.

53
00:03:30,120 --> 00:03:35,610
The next step is for Santos of Red Hat Fedora version seven.

54
00:03:35,610 --> 00:03:38,580
You will have to run the command command jam, DNF.

55
00:03:38,580 --> 00:03:43,230
DNF is going to be replacing Yum eventually.

56
00:03:43,500 --> 00:03:50,220
So for now you could use either or so install EPL Daschle's and then install Ansible.

57
00:03:50,430 --> 00:03:57,720
Now for Santas eight or any of the version eight, this is these are the instructions that we will follow

58
00:03:57,720 --> 00:04:03,630
going back to our Linux machine to follow these instructions and install any package we have to run

59
00:04:03,630 --> 00:04:07,350
the command as root, so become root.

60
00:04:08,840 --> 00:04:11,450
All right, now go ahead and run the command.

61
00:04:11,450 --> 00:04:12,050
Yum.

62
00:04:12,050 --> 00:04:16,580
Install epi l release.

63
00:04:24,090 --> 00:04:24,840
All right.

64
00:04:24,840 --> 00:04:29,340
It's asking you to confirm a type of lie and confirm again.

65
00:04:29,520 --> 00:04:32,250
And the package has been installed.

66
00:04:32,280 --> 00:04:32,580
All right.

67
00:04:32,580 --> 00:04:35,220
The next thing is jump install python.

68
00:04:35,700 --> 00:04:44,400
Now with Santos eight or newer version of Red Hat or Linux, the Python package should already be installed

69
00:04:44,610 --> 00:04:54,000
or installed out of the box to confirm that you can run the command rpm way and grep for python and

70
00:04:54,000 --> 00:04:58,290
you'll notice they these are all the list of python packages that's already been installed.

71
00:04:58,380 --> 00:04:59,010
Great.

72
00:04:59,040 --> 00:05:01,590
Now the next step is to install Ansible.

73
00:05:01,830 --> 00:05:06,240
So let's clear the screen and type it in Yum or DNF.

74
00:05:06,240 --> 00:05:08,790
So in this this time we'll run DNF.

75
00:05:10,160 --> 00:05:14,780
Install Ansible, this is the Ansible engine or software itself.

76
00:05:14,840 --> 00:05:22,370
And then the next package that we will install in addition to Ansible is the Ansible documentation and.

77
00:05:31,060 --> 00:05:36,490
All right, Ansible and Ansible, dock package is completed to verify it.

78
00:05:36,490 --> 00:05:39,940
You can run the command rpm queue and grep for ansible.

79
00:05:41,700 --> 00:05:42,000
All right.

80
00:05:42,000 --> 00:05:42,660
That's their answer.

81
00:05:42,660 --> 00:05:49,470
BAKER And well, Doc, the next thing is, if you are using CentOS eight, eight and the above steps

82
00:05:49,470 --> 00:05:52,200
don't work, then follow these steps.

83
00:05:52,200 --> 00:05:55,050
So usually version eight will come with Python three.

84
00:05:55,500 --> 00:05:57,810
If it's not, then you follow these steps.

85
00:05:57,900 --> 00:06:06,270
Yum, install python three and then use python package installer to install Ansible, which is pip three,

86
00:06:06,270 --> 00:06:08,580
install ansible dash dock.

87
00:06:08,880 --> 00:06:09,420
All right.

88
00:06:09,420 --> 00:06:15,630
Moving on, if you're using RedHat eight and above steps that you followed did not work, then you have

89
00:06:15,630 --> 00:06:21,780
to enable the Ansible engine repository to install Ansible and for that you will run the command subscription

90
00:06:21,780 --> 00:06:27,810
dash manager repos enabled ansible repositories and then install Ansible.

91
00:06:28,260 --> 00:06:28,620
All right.

92
00:06:28,620 --> 00:06:34,980
So now after Ansible has been successfully installed on your Linux machine, let's confirm.

93
00:06:35,690 --> 00:06:37,760
So here is our Linux machine.

94
00:06:37,760 --> 00:06:41,360
Let's clear the screen and you will run the command and.

95
00:06:42,740 --> 00:06:43,190
Dash.

96
00:06:43,190 --> 00:06:44,220
Dash version.

97
00:06:45,350 --> 00:06:51,290
And it will give you the version of the astral engine or Ansible software that has been installed.

98
00:06:51,440 --> 00:06:51,950
All right.

99
00:06:51,950 --> 00:06:52,670
It is there.

100
00:06:52,670 --> 00:06:53,860
We confirm that.

101
00:06:53,870 --> 00:06:58,970
Now run ansible command module using Peng.

102
00:06:59,000 --> 00:07:00,560
So it will be Ansible.

103
00:07:00,830 --> 00:07:02,090
Local host.

104
00:07:02,930 --> 00:07:15,290
Dash M Peng This command is going to run as a module called Peng against the local host so simply as

105
00:07:15,290 --> 00:07:16,720
if you are doing ping.

106
00:07:16,790 --> 00:07:20,870
Local host and it is pinging and confirming it could ping.

107
00:07:20,870 --> 00:07:22,530
The local host just like that.

108
00:07:22,550 --> 00:07:25,810
We have a ping module within Ansible, by the way.

109
00:07:25,820 --> 00:07:29,960
There are many, many, many more modules that we will cover later on.

110
00:07:29,960 --> 00:07:35,510
But for now this is what I wanted to confirm, to see if Ansible has been installed.

111
00:07:35,780 --> 00:07:38,150
All right, let's check the Ansible config files.

112
00:07:38,570 --> 00:07:40,960
So let's clear the screen again.

113
00:07:40,970 --> 00:07:50,060
The Ansible files, all of them are located in at see Ansible and you do listing of the files and directories.

114
00:07:50,060 --> 00:07:53,420
You'll see there are roles directory which we will cover later on.

115
00:07:53,450 --> 00:07:55,280
Then there is a host file.

116
00:07:55,280 --> 00:08:00,020
That's where all the remote clients inventory resides.

117
00:08:00,020 --> 00:08:07,730
So we every time we run a Ansible command, it comes to this file to see where the list of all the hosts

118
00:08:07,730 --> 00:08:11,300
or remote clients that it has to execute the commands on.

119
00:08:11,420 --> 00:08:13,380
And the last one is Ansible CFG.

120
00:08:13,410 --> 00:08:18,950
If you need to make any configuration change on Ansible, you could do it on this configuration files.

121
00:08:19,490 --> 00:08:20,050
All right.

122
00:08:20,060 --> 00:08:26,840
The last thing, please note, if you have Linux enabled on remote nodes, you will also want to install

123
00:08:26,870 --> 00:08:32,450
lib linux dash python on them before using any copy file template related function ansible.

124
00:08:32,780 --> 00:08:36,560
Now you do not have to go log into each and every one of them.

125
00:08:36,800 --> 00:08:42,890
What you could do is you can use the Yum module or DNF module in Ansible to install this package under

126
00:08:42,890 --> 00:08:45,260
remote hosts that do not have it.

127
00:08:45,920 --> 00:08:53,480
All right, so we will disable the Linux on our remote client because we are using all that set up in

128
00:08:53,480 --> 00:08:54,410
our lab environment.

129
00:08:54,410 --> 00:09:01,280
But if you're doing in production, then please make sure you install this lib as Linux dash python

130
00:09:01,490 --> 00:09:02,360
package.

131
00:09:03,110 --> 00:09:03,410
All right.

132
00:09:03,410 --> 00:09:08,500
So now this completes our entire lab setup and configuration.

133
00:09:08,510 --> 00:09:16,310
Now it's time to really get our hands dirty and run our Ansible automation scripts against our local

134
00:09:16,310 --> 00:09:18,020
host and remote clients.
