5.5 Automating EC2 Bootstrap

00:00

In this video,

00:02

we will

00:03

right a bash scrip to automate our easy to security updates

00:07

and create a bash Script to launch are easy to Web server.

00:13

In our last video,

00:15

we downloaded and used putty toe log in tow. RTC to instance

00:20

we also use Putty Jin to convert our pen file into a PPK file.

00:25

In this video,

00:27

we will really step up our game and automate the EEC to bootstrap process.

00:32

We will also configure and launch our easy to Web server via bash script.

00:38

So, in essence, everything that we have been doing throughout the past few easy to videos

00:43

manually.

00:45

Such is

00:47

updating our Lennix Am mine. Installing our Apache servers,

00:51

we will combine into a script that will automate all of these tasks.

00:56

For those who may not be familiar, bash stands for

01:00

the born again shell.

01:02

It's a command line interpreter

01:03

that's included with most Lennox distributions.

01:07

It's used for scripting to do such things as read files or execute commands.

01:12

Now our course won't make you a bash expert.

01:17

However, I highly recommend that you continue learning more about bash and other scripting. Language is such as python

01:23

to really take your career to the next level.

01:27

The first thing that we will need to do is create a landing page for a Web server.

01:32

I've created a basic HTML foul

01:34

that says today I am honored to teach you how to automate the EEC to bootstrap process.

01:42

We will need to upload this file

01:45

to an S three bucket,

01:49

So let's log into the console

01:52

and select s3

01:57

click Create bucket.

02:01

Let's give the bucket a unique name.

02:04

I will name mine Cyber Very Dash E C to Dash Automation Dash Demo,

02:10

then click Create bucket.

02:16

Next, we want to attach a role.

02:21

So let's go back out to the console and select I am.

02:29

Then click rolls from the menu on the left

02:35

click create role

02:38

we will slay easy to

02:44

then

02:45

next. Permissions

02:47

in the filter type s3 To select the S tree policies,

02:55

select

02:57

Amazon ist three Full access,

03:00

then click review.

03:06

Let's give our role of name.

03:08

I will call mine

03:09

E C. To underscore

03:13

can underscore Call underscore history

03:16

and

03:17

I will update the description.

03:28

Finally click create role

03:34

and our new role has been created.

03:40

Now let's go back to our newly created as three bucket,

03:45

we will need to upload our static Web page that we created.

03:53

Next. Let's go back to the console

03:57

and click on Easy to.

04:01

Then click Launch instance.

04:08

You select the Amazon Lennox to am I

04:13

t to Micro is our instance type.

04:16

Then click

04:17

configure instance. Details.

04:20

Navigate down to where it says

04:24

I am role.

04:28

Then from the dropdown,

04:30

select our easy to can call as three roll

04:34

scroll down to advanced details,

04:40

then click inside the user data box.

04:43

This is where we create our bash scrip.

04:46

Usually one would create the script in the text editor, but since this is a learning demo, we could place are short script directly into the window, line by line.

04:56

This will give us a chance to learn what each command is doing within the script.

05:01

The first line that we type is called the Shebang.

05:05

This is the pound sign, followed by an exclamation point

05:10

and then the path to the bash Interpreter.

05:15

Next

05:15

we run Yemen stall H T T P D

05:19

Dash. Why?

05:20

To install our Apache server.

05:25

Next we run yum

05:27

update dash y

05:29

to install any security updates.

05:35

Next,

05:36

we will have our E. C. Two Instance, copy our static Web page that we uploaded into Rs Tree Bucket

05:44

to the HTML directory of our new Apache server.

05:59

Next

06:00

we run service H T T p d start

06:03

to start our Apache server,

06:06

and finally,

06:09

we will run the check config. H t t p d on command.

06:14

This command will check to see if the Apaches service is running on our instance,

06:18

just in case our session gets terminated.

06:23

Next, click, add storage,

06:28

click add volume,

06:31

accepted the faults and then click add tags.

06:38

Then select Configure Security Group.

06:41

We will use our existing security group that we created. In a previous lesson,

06:46

Cy Berry underscored Demo underscored DMC

06:49

Now Click Review and Launch

06:53

perform a final review.

06:56

Then Click Launch.

07:00

We will use the existing key pair that we created in previous lesson,

07:04

Then click launch Instances,

07:09

then select view instances

07:13

in the filter. I like to type pending and running to clear out in the stop determinate instances.

07:20

And now that we see are instances

07:23

are being created.

07:27

Once running, our instance will execute the script that we added in the user data box.

07:39

So

07:40

now are instances up in running.

07:43

I will copy the public I p address to the clipboard.

07:55

Next, we will open a browser

07:57

and see if our script worked.

08:01

We expect to see a fully patched and functioning Web server

08:05

hosting our HTML page that we uploaded to RST bucket

08:13

and there's our Web page.

08:16

So just to summarize,

08:18

before we even created this instance,

08:20

we created an HTML page.

08:24

Then we created a new S three bucket

08:28

that we uploaded our HTML file into.

08:31

We then created a new E C to roll, and I am

08:35

that has full access to as three buckets.

08:39

Next, we launched a new easy to instance.

08:43

We instructed it to install the Apache server,

08:46

install any security updates,

08:50

copy the HTML page from Rs three bucket

08:54

to the HTML directory of our Apache server,

08:58

turn on the Apache server

09:01

and check to ensure that the servers running

09:05

all of this was done from a few lines of a bash grip.

09:09

That, my friends, is just a taste of the power of automation.

09:15

Congratulations, everyone, Fantastic job.

09:20

In this video,

09:22

we wrote a bash grip toe automate R E C two security updates,

09:26

and
