Lab steps

  1. Launch EC2 Instance. Use the following User data:
    #!/bin/bash
    
    sudo su
    
    yum update -y
    
    yum install httpd -y
    
    echo "<html><h1> Welcome to Whizlabs Server 1 </h1><html>" >> /var/www/html/index.html
    
    systemctl start httpd
    
    systemctl enable httpd

    Attach a Security Group allowing inbound traffic for SSH and HTTP from anywhere.

  2. Test the Apache server by navigating to the instances Public IP.
  3. Create a Snapshot of EC2 Instance. Under Elastic block Store navigate to Snapshots and create volume snapshot of your instance volume.
  4. Create AMI with Snapshot. Select the created snapshot, clock on Actions and select Create Image.
  5. Next create an EC2 Instance using newly create AMI. Navigate to AMIs and launch new instance of type t2.micro and add User data
    #!/bin/bash -ex 
    
    sudo service httpd restart

    Attach the previously created security group.

  6. When the new instances status is running navigate to its Public IP and you should get the same response as from server 1 (notice different IP address):
