Ansible-Orchestrated-Apache-Web-Hosting-on-AWS-EC2

This project demonstrates the setup and configuration of a multi-server environment using Ansible on AWS EC2. The goal of this project is to host an Apache server on multiple Ubuntu servers.

Prerequisites

• AWS account with appropriate permissions to launch EC2 instances.
• Ansible installed on the master server.

Setup

1. Launch Ubuntu EC2 instances on AWS:

   • Launch four instances with the following names: master, server-1, server-2, server-3.
   • Ensure that all instances are launched with the same configuration, key pair, and security group.

2. Access the master server:

   • Connect to the master server using SSH.
   • Install Ansible on the master server.

3. Configure SSH access:

   • In the path ./ssh, create a file named my-key.
   • Copy and paste the key pair that you used while launching the servers into this file.
   • Run the following command:

     $ cd ./ssh
     $ vi my-key
     # Copy and paste the key pair into the file, save, and exit.
     

4. Configure inventory file:

   • By default, the inventory file is stored in /etc/ansible/hosts. If it doesn't exist, create a new folder named ansible and inside that folder, create the inventory file named hosts.
   • Run the following commands:

     $ sudo mkdir /etc/ansible
     $ sudo vi /etc/ansible/hosts
     

   • Add the details of the nodes in the following format:

     [nodes]
     server-1 ansible_host=<server-1 IP address>
     server-2 ansible_host=<server-2 IP address>
     server-3 ansible_host=<server-3 IP address>
     

5. Check inventory information:

   • Run the following command to display the inventory information:

     $ ansible-inventory --list -y -i /etc/ansible/hosts
     

6. Ping all nodes:

   • Run the following command to ping all nodes:

     $ ansible all -m ping -i /etc/ansible/hosts --private-key=~/.ssh/my-key
     

7. Configure playbook:

   • Create a file named test.yaml in the Ansible project directory.
   • Write the necessary Ansible playbook code to install and configure Apache on the target nodes.
   • Run the following command:

     $ vi test.yaml
     # Add the playbook code, save, and exit.
     

8. Execute the playbook:

   • Run the following command from the Ansible project directory:

     $ ansible-playbook test.yml -i /etc/ansible/hosts --private-key=~/.ssh/my-key
     

9. Verify the setup:

   • Access the IP addresses of server-1, server-2, and server-3 in a web browser.
   • You should see the default Apache page indicating a successful deployment.
