Install Apache package in EC2 instance using Terraform

Description: In the previous topic, I have explained, How to create a blank EC2 instance using Terraform. In this topic, I am creating an EC2 instance with a Pre-installed Apache package with the instance.

• First I am creating an apache install shell script for Linux with the name install-apache.sh as follow and save it on the project folder

# installl-apache.sh
#!/bin/bash -xe
cd /tmp
yum update -y
yum install -y httpd
echo "Hello from the EC2 instance $(hostname -f)." > /var/www/html/index.html
systemctl start httpd

• After creating the script file, Now I am creating terraform project file to create EC2 Instance  as follow

provider "aws" {
    access_key = "AKIAU4DZPCIQVSO67EPG"
    secret_key = "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"
    region = "us-east-1"
}

resource "aws_instance" "Webserver" {
  ami           = "ami-0d5eff06f840b45e9"
  instance_type = "t2.micro"
  tags = {
    Name = "Web server"
  }
  vpc_security_group_ids = [ "sg-01df6b2fc0470ce65" ]
  user_data = "${file("install_apache.sh")}"
  key_name = "Ansible"
}

• Now, I am going to run terraform project using terraform terminal as follow

# terraform init

• To review terraform project run terraform plan to list action 

# terraform plan

• After review, Apply project using terraform apply command

# terraform apply

• Now verify the instance, by browsing the IP address in the browser. Also, make sure to allow port 80 [HTTP] service in the security group which you have used in terraform project
