Install Apache Server in Ubuntu EC2 instance using Terraform

2 min readDec 16, 2022

Hi everyone,

This article will show you how you can create an Ubuntu EC2 instance and install Apache Server in a single go without any manual intervention.

Prerequisite:

Generate a key pair of .pem extension since we need to have SSH access to an Ubuntu Instance.

Terraform file important actions:

Creates an Security group and adds the necessary Inbound(Ingress)/Outbound(Egress) rules
The Security Group is attached to an EC2 instance.
The Key pair name is specified which is attached to the instance.
The Key is used for SSH connection to the Instance.

The “remote-exec” provisioner block spcifies the commands that needs to be run in the remote instance after the instance is created.

The Public IP of the instance is the Output which serves the Apache server.

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

resource "aws_security_group" "remote_exec_sg" {
 name = "SG-1"
 
 ingress {
  from_port = 80
  to_port = 80
  protocol = "tcp"
  cidr_blocks = ["0.0.0.0/0"]
 }

 ingress {
  from_port = 443
  to_port = 443
  protocol = "tcp"
  cidr_blocks = ["0.0.0.0/0"]
 }

 ingress {
  from_port = 22
  to_port = 22
  protocol = "tcp"
  cidr_blocks = ["0.0.0.0/0"]
 }

 egress {
  from_port = 0
  to_port = 0
  protocol = "-1"
  cidr_blocks = ["0.0.0.0/0"]
 }

}

    host     = self.public_ip
  }

  provisioner "remote-exec" {
    inline = [
     "sudo apt-get install apache2 -y",
     "sudo systemctl start apache2",
     ]
   }
}
