Project: Deploy Multiple EC2 Instances on AWS Using Terraform

Prerequisites

• AWS Account: Ensure you have an active AWS account.
• SSH Key Pair: Create an SSH key pair in your AWS account and download the .pem file.
• Amazon Linux Instance: Ensure you have an Amazon Linux instance running with access to install and run Terraform.

Step 1: Install Terraform on Amazon Linux

1. Update Package Repository:

   sudo yum update -y

2. Download and Unzip Terraform:

   wget https://releases.hashicorp.com/terraform/1.0.11/terraform_1.0.11_linux_amd64.zip
   unzip terraform_1.0.11_linux_amd64.zip -d /usr/local/bin

3. Verify Terraform Installation:

   terraform -version

Step 2: Configure AWS CLI

1. Install AWS CLI (if not already installed):

   sudo yum install aws-cli -y

2. Configure AWS CLI:

   aws configure

   • Enter your AWS Access Key ID, Secret Access Key, Default region name (us-east-2), and Default output format (e.g., json).

Step 3: Create a Terraform Configuration File

1. Create a Project Directory:

   mkdir aws-multi-server
   cd aws-multi-server

2. Create and Edit main.tf:

   nano main.tf

3. Add the Following Configuration to main.tf:

   provider "aws" {
     region = "us-east-2"
   }
   
   resource "aws_security_group" "allow_ssh" {
     vpc_id = "vpc-07c013bc2e179830d"  # Your VPC ID
   
     ingress {
       from_port   = 22
       to_port     = 22
       protocol    = "tcp"
       cidr_blocks = ["0.0.0.0/0"]
     }
   }
   
   resource "aws_instance" "web" {
     count         = 3
     ami           = "ami-0942ecd5d85baa812"  # Your AMI ID
     instance_type = "t2.micro"
     subnet_id     = "subnet-0b313bf9dfbc70934"  # Your Subnet ID
     vpc_security_group_ids = [aws_security_group.allow_ssh.id]
   
     tags = {
       Name = "WebServer-${count.index + 1}"
     }
   }

4. Save and Exit:

   • In Nano, press Ctrl + O, Enter, then Ctrl + X to save and exit the editor.

Step 4: Initialize and Apply the Terraform Configuration

1. Initialize Terraform:

   terraform init

2. Plan the Deployment:

   terraform plan

3. Apply the Configuration:

   terraform apply

   • When prompted to confirm, type yes and press Enter.

Step 5: Verify the Deployment

1. Check AWS Management Console:

   • Go to the EC2 Dashboard in the AWS Management Console.
   • Verify that three EC2 instances have been created, each tagged as WebServer-1, WebServer-2, and WebServer-3.

   

2. SSH into Instances:

   • Use the public IP addresses of the instances to SSH into them from your PuTTY session. For example:

     ssh -i "C:\Users\nomii\Downloads\Syed1.pem" ec2-user@<public-ip-of-instance>

   • Replace <public-ip-of-instance> with the actual public IP address of each instance.
