5.3 Create Your First EC2 Instance Part 2

00:00

welcome back to part two of our easy to lab.

00:03

As you can see, we're on my *** unto Lennox VM.

00:09

I am using the linens, Veum,

00:11

because it is much easier interact with are easy to instance natively

00:15

from the terminal.

00:17

If you are using a windows machine for this video,

00:20

then you will need to download putty.

00:23

For those of you who may not be familiar with putty,

00:26

it's a free terminal emulator

00:29

that will lie you to interact with your PC. To instance,

00:34

some things are slightly different.

00:36

So I will make a second video to show you how to set up putty from a Windows box.

00:42

So if you recall from the last lesson

00:45

I downloaded the private key that AWS generated for us

00:49

to my documents directory.

00:52

So what I will do now is create a new directory

00:56

called

00:57

sshh, underscore keys.

01:03

I will run the L s command

01:06

to ensure that the new directory has been created.

01:11

Is there good?

01:12

So

01:14

now I will move our private key to the SS H Keys directory.

01:23

Next,

01:23

let's change into that directory.

01:27

We will run a L s command again to verify that the move was successful.

01:33

Awesome.

01:34

Now we need to change the permissions on our private key to make it read only

01:41

this is very important for the security of our private key.

01:44

So

01:46

let's make ourselves route,

01:49

then run ch mod

01:52

400

01:53

to make the file permissions read. Only

02:01

we can verify the commission by running

02:05

l s

02:07

space dash A L.

02:09

This shows us that the file is now read only.

02:14

So

02:15

now we are ready to log into our e c two instance

02:21

we need to type

02:22

sssh space e c to dash

02:25

user

02:28

at

02:32

Then we paste in that public i p address that we copied from the last lesson.

02:38

Next

02:40

we provide the dash I flag, which is telling our easy to instance to read the identity file,

02:47

which is our private key for authentication.

02:53

So

02:53

let's copy and paste our file name.

02:57

Remember that without this private key, we will not be able to authenticate toh ar e c two instance

03:04

hit enter

03:08

And now we see the EEC, to instance, has responded to us

03:13

and it's telling us that has never seen our key before.

03:17

This is normal for the first time that we log in.

03:21

So we type Yes.

03:23

And now the EEC, to instance, will add a copy of our key toe a host file.

03:30

The next time that we log in, it will compare the key that we present

03:34

to the one in its host file and basically will say, Oh, yeah, I know you already

03:45

Now we have successfully authenticated toe are easy to instance,

03:51

if you recall from previous lessons

03:53

A W S provides the basic operating system that are easy to system will run on

04:00

We are responsible for the security updates software etcetera

04:04

A. W s calls this the shared responsibility model

04:11

right away

04:13

R e c two instances informing us

04:15

that we need to apply at least six of the 14 security updates

04:19

that are available, for instance.

04:24

So

04:25

let's update those now

04:29

we need to change to root.

04:31

Now

04:32

this part is a matter of preference.

04:35

We use yum toe update this flavor of lyrics.

04:40

Since this will be our Web server,

04:42

I like to install the Web server first

04:45

and then apply all the updates.

04:47

So let's type yum space install

04:51

space. H t t p D

04:56

to load Apache server.

04:59

We had a dash why,

05:00

so that it was installed without prompting us.

05:05

Next we perform a young update dash. Why?

05:10

To install the necessary system updates.

05:24

Next,

05:25

Let's create a landing page for our Web server.

05:29

We change directories to force Last bar forward slash dubbed dubbed up

05:34

forward slash html.

05:44

From here, we use a text editor.

05:46

I use Nano

05:47

to make a static home page for our Web server.

05:53

We will name the file index dot html,

06:02

and I will paste in simple HTML coat,

06:06

then click control Dash X to close out the file.

06:12

When asked to save

06:14

perform a shift. Why, then enter?

06:19

Awesome.

06:21

Next,

06:23

we need to enable the Apache server on our instance.

06:28

So we type

06:29

service space.

06:30

H t t p d Space start, then enter.

06:39

Finally, we are ready to test our Web server.

06:43

Let's open up a browser

06:46

and type in the I. P address of our easy to instance

06:56

Hit Enter

06:58

and there is our web page.

07:00

Great job, everyone.

07:09

In this video,

07:11

we created our first easy to instance,

07:15

we created our first security group.

07:19

We created a P K I I ke pair for our easy to instance,

07:25

and

07:26

we created a Web server
