9 Ways to Launch an AWS EC2 Instance (2022)

And also how to configure a web server on it

9 Ways to Launch an AWS EC2 Instance (1)

What is AWS?

Amazon Web Services (AWS) is the world’s most comprehensive and broadly adopted cloud platform, offering over 200 fully-featured services from data centers globally. Millions of customers — including the fastest-growing startups, largest enterprises, and leading government agencies — are using AWS to lower costs, become more agile, and innovate faster.

What is an EC2 instance?

An Amazon EC2 instance is a virtual server in Amazon’s Elastic Compute Cloud (EC2) for running applications on the Amazon Web Services (AWS) infrastructure.

what is Apache Web Server?

Apache is the most commonly used Web server on Linux systems. Web servers are used to serve Web pages requested by client computers. Clients typically request and view Web pages using Web browser applications such as Firefox, Opera, Chromium, or Internet Explorer.

Here are the different types of launching AWS EC2 instance & configuring Web Server:

We can launch EC2 instance and configure web server on it manually.

Go to EC2 and click on launch instance

9 Ways to Launch an AWS EC2 Instance (2)

Select AMI for your instance

9 Ways to Launch an AWS EC2 Instance (3)

Choose an Instance type

9 Ways to Launch an AWS EC2 Instance (4)

For configure the instance, Add Storage and Add Tags we can leave by default setting.

Next, we need to Edit the Security group so that we can connect to our webserver.

9 Ways to Launch an AWS EC2 Instance (5)

Next click on Review and launch and when you click on launch you will have to create a key pair which we can use later to login into our EC2 instance.

Finally, Launch Instance.

After launching go onto that instance and click on Connect.

9 Ways to Launch an AWS EC2 Instance (7)

Click on Connect a new tab will open with your EC2 instance.

9 Ways to Launch an AWS EC2 Instance (8)

For Configuring webserver, Type the following commands

sudo su -rootyum install httpd -ycd /var/www/htmlvi index.html (press i to enter content, esc to exit from insert and Enter :wq to save the file )systemctl start httpd

After running this command your webserver will be configured and you can access it by using your public IP.

We can launch the EC2 instance using our command prompt.

First, we need to install aws cli in our Operating System
https://docs.aws.amazon.com/cli/latest/userguide/install-cliv2-windows.html

After installation and configuration, we need to run the following command to launch the EC2 instance.

(Video) Launch an EC2 Instance in AWS free tier account | How to launch and terminate ec2 |concepts of cloud

$ aws ec2 run-instances --image-id ami-xxxxxxxx --count 1 --instance-type t2.micro --key-name MyKeyPair --security-group-ids sg-903004f8 --subnet-id subnet-6e7f829e

It will successfully launch the instance. After that, we have to do SSH for configuring EC2, for that we will use the following command

ssh -i file.pem username@ip-address

Now you can configure the webserver

For configuring the webserver, type the following commands:

sudo su -rootyum install httpd -ycd /var/www/htmlvi index.html (press i to enter content, esc to exit from insert and Enter :wq to save the file )systemctl start httpd

After running this command your webserver will be configured and you can access it by using your public IP.

Terraform is an infrastructure as code (IaC) tool that allows you to build, change, and version infrastructure safely and efficiently. This includes low-level components such as compute instances, storage, and networking, as well as high-level components such as DNS entries, SaaS features, etc. Terraform can manage both existing service providers and custom in-house solutions.

How can we launch Instance and configure the webserver?

Install terraform- https://www.terraform.io/downloads.html.

Create a folder and inside it create a file with the extension (.tf).

You can use the below code for launching and configuring the webserver:

provider “aws” {region = “ap-south-1”access_key = “Enter_your_access_key”secret_key = “Enter_your_secret_key “}resource aws_instance “web”{ami = “ami-010aff33ed5991201”instance_type = “t2.micro”security_groups = [ “launch-wizard-1” ]key_name = “Enter_your_key_name”tags = {Name = “webserver”}}resource “aws_ebs_volume” “et1”{availability_zone = aws_instance.web.availability_zonesize = 5tags = {Name = “myvoll”}}resource “aws_volume_attachment” “vol_att” {device_name = “/dev/sdh”volume_id = aws_ebs_volume.et1.idinstance_id = aws_instance.web.id}resource “null_resource” “nullres1”{connection{type = “ssh”user = “ec2-user”private_key = file(“Enter_your_key_path”)host = aws_instance.web.public_ip}provisioner “remote-exec” {inline = [“sudo yum install httpd -y”,“sudo yum install php -y”,“sudo systemctl start httpd”,“sudo systemctl start httpd”]}}resource “null_resource” “nullres2”{connection{type = “ssh”user = “ec2-user”private_key = file(“Enter_your_key_path “)host = aws_instance.web.public_ip}provisioner “remote-exec” {inline = [“sudo mkfs.ext4 /dev/xvdh”,“sudo mount /dev/xvdh /var/www/html”,“sudo yum install git -y”,“sudo git clone https://github.com/tejas0207/php-test /var/www/html/web”]}}resource “null_resource” “nullres3”{provisioner “local-exec”{command = “chrome http://{aws_instance.web.public_ip}/web/index.php"}}

Now in the command prompt, switch to the folder which contains code.

After that run these commands:

terraform init

terraform plan

terraform apply (Enter yes when prompted)

Here launching EC2 is similar to console but there is a change in configuring the webserver.

When you go for launching EC2 via console, go to step3 Configure Instance Details

Scroll down to Advanced settings, where you can see User data. In that, you can add commands which you want your instance to run during boot time. It can be a file or raw commands. The file should be in a language that is supported by your instance.

For eg. Here I have used a shell script:

(Video) How to launch ec2 instance in aws | ec2 instance | aws ec2 | aws

#!/bin/bashyum install httpd -yx=$(curl http://169.254.169.254/latest/meta-data/placement/availability-zone)echo $x > /var/www/html/index.htmlip=$(curl http://169.254.169.254/latest/meta-data/public-ipv4)echo $ip >> /var/www/html/index.htmlsystemctl start httpdsystemctl enable httpd

After this do the rest launching steps and your instance will be launched and configured.

5. CloudShell

9 Ways to Launch an AWS EC2 Instance (9)

Click on that symbol, It will open a new tab and configure your AWS CloudShell environment.

After this step is the same as AWS CLI:

$ aws ec2 run-instances --image-id ami-xxxxxxxx --count 1 --instance-type t2.micro --key-name MyKeyPair --security-group-ids sg-903004f8 --subnet-id subnet-6e7f829e

It will successfully launch the instance

After this Put your SSH key into some private bucket, then use AWS S3 cp to copy it to your CloudShell instance.

Follow the instructions you get when you click on the “Connect” button in your EC2 instance dashboard. For instance, you need to run (only once) a chmod 400 on your SSH key, and you also need to know the IP of your EC2 instance.

After that, we have to do SSH for configuring EC2, for that we will use the following command

ssh -i file.pem username@ip-address

Now you can configure the webserver

For Configuring webserver, Type the following commands

sudo su -rootyum install httpd -ycd /var/www/htmlvi index.html (press i to enter content, esc to exit from insert and Enter :wq to save the file )systemctl start httpd

After running this command your webserver will be configured and you can access it by using your public IP.

6. Custom AMI

It is almost the same as launching an ec2 instance via console or any other type, there is just a slight change in the image of the instance. Here we will use a pre-configured template or AMI and the rest steps will be exactly the same as launching.

7. Python+ Pulumi

Install some necessary Python packages:

sudo apt install python-dev -ysudo apt install python3-pip -ysudo apt install python3-venv -y

Create a new Stack:

pulumi new aws-python — name webserver-pulumi — stack webserver

(Video) How to Automatically Stop/Start EC2 instances using AWS Lambda| Cloudwatch Events Scheduler

Once the stack files are created, use the following to create a virtual env and install requirements:

python3 -m venv venvsource venv/bin/activatepip3 install -r requirements.txt

requirement.txt

pulumi>=1.0.0pulumi-aws>=1.0.0

Main file(__main__.py)

import pulumiimport pulumi_aws as aws# Define some variables to use in the stacksize = “t2.micro”vpc_id = “vpc-xxxxxx”subnet_id = “subnet-xxxxxx”public_key = “ssh-rsa xxxxxxxxxxxxxxxxxxxxxxx”user_data = “””#!/bin/bashsudo apt updatesudo apt install apache2 -yecho ‘Hello World!’ > /var/www/html/index.html”””# Get the AMI ID of the latest Ubuntu 18.04 version from Canonicalami = aws.get_ami(most_recent=”true”,owners=[“099720109477”],filters=[{“name”: “name”,“values”: [“ubuntu/images/hvm-ssd/ubuntu-bionic-18.04-amd64-server-*”],}],)# Create an AWS Key Pairkeypair = aws.ec2.KeyPair(“keypair-pulumi”,key_name=”keypair-pulumi”,public_key=public_key,tags={“Name”: “keypair-pulumi”},)# Create an AWS Security group with ingress and egress rulesgroup = aws.ec2.SecurityGroup(“securitygroup-pulumi”,description=”Enable access”,vpc_id=vpc_id,ingress=[{“protocol”: “tcp”,“from_port”: 22,“to_port”: 22,“cidr_blocks”: [“0.0.0.0/0”],},{“protocol”: “tcp”,“from_port”: 80,“to_port”: 80,“cidr_blocks”: [“0.0.0.0/0”],},],egress=[{“protocol”: “-1”, “from_port”: 0, “to_port”: 0, “cidr_blocks”: [“0.0.0.0/0”],}],tags={“Name”: “securitygroup-pulumi”},)# Create the webserver EC2 instanceserver = aws.ec2.Instance(“webserver-pulumi”,instance_type=size,vpc_security_group_ids=[group.id],user_data=user_data,ami=ami.id,key_name=keypair.key_name,subnet_id=subnet_id,tags={“Name”: “webserver-pulumi”},)# Show the Public IP address of the webserver EC2 instancepulumi.export(“publicIp”, server.public_ip)

To create or update the infrastructure, use: pulumi up

If you’re done with the stack and want to remove it use: pulumi destroy

8. CloudFormation

Go to AWS console and search for cloudformation:

9 Ways to Launch an AWS EC2 Instance (11)

Click on create a stack.

You can use JSON or YAML code for launching instances and configuring the webserver.

9 Ways to Launch an AWS EC2 Instance (12)

Create a template.yaml in local storage and use the below code:

Resources:Ec2Instance:Type: AWS::EC2::InstanceProperties:InstanceType: t2.microImageId: ami-0947d2ba12ee1ff75KeyName: aws_keyTags:- Key: NameValue: My EC2 InstanceUserData:Fn::Base64: !Sub |#!/bin/bashyum update -yyum install -y httpdecho “Hello World” > /var/www/html/index.htmlsystemctl start httpdsystemctl enable httpd

After uploading the file create the stack, after few seconds it will automatically launch the EC2 instance and configure web server on it.

9. Ansible

Configure your system with Ansible: https://docs.ansible.com/ansible/latest/installation_guide/intro_installation.html

Create a file with (.yml) extension. Use the following code:

- hosts: localhostvars_files:- credential.ymltasks:- ec2_instance:region: ‘ap-south-1’name: ‘Test1’tags:Environment: Testingimage_id: ‘ami-04b1ddd35fd71475a’instance_type: ‘t2.micro’vpc_subnet_id: ‘subnet-18212870’security_groups: ‘sg-0edd29029017df107’key_name: ‘mymainkey1122’state: present- name: start an instance with a public IP addressec2_instance:name: “public-compute-instance”key_name: “prod-ssh-key”vpc_subnet_id: subnet-5ca1ab1einstance_type: ‘t2’security_group: default- debug:msg: ‘{{ansible_facts}}’- hosts: tag_Environment_Testingtasks:- package:name: httpd- copy:content: “webserver configured”dest: “/var/www/html/index.html”- service:name: httpdstate: started
