Task 1

Create 3 EC2 instances. make sure all three are created with the same key pair

Install Ansible on a host server

Connect the master server by using SSH.
To add the Ansible PPA (Personal Package Archive) repository, you can execute the command below:
```
  sudo apt-add-repository ppa:ansible/ansible
```
Update the package.
Install Ansible using the following command:
```
  sudo apt install ansible
```
Verify the installation.

Copy the private key from local to the Host server (Ansible_host) at (/home/ubuntu/.ssh)

Go to the .ssh folder and copy the path.

Run the below command to copy the ansible key file on the server followed by the copied path

  sudo scp -i "ansible-key.pem" ansible-key.pem ubuntu@ec2-18-232-124-214.compute-1.amazonaws.com:/home/ubuntu/.ssh

Check the folder again and see if the key file is there. Now change the permission of the key file

Access the inventory file using sudo vim /etc/ansible/hosts

Edit the hosts file by using sudo vim /etc/ansible/hosts command.
Once you have added the host information to the file, you can check the list of hosts that Ansible can work with by using the "ansible-inventory --list -y" command.
Ping the nodes by using ansible servers -m ping command.

Create a playbook to install Nginx

Create a playbooks folder and inside that folder create a file.

Paste the below code in the file.

  ---
  - name: This playbook will install nginx
    hosts: all
    become: true
    tasks:
      - name: Update apt
        apt:
          update_cache: yes
      - name: Install nginx
        apt:
          name: nginx
          state: latest
      - name: start and enable nginx
        service:
          name: nginx
          state: started
          enabled: yes

Run the playbook by using the ansible-playbook command
Check on the server to verify if the Nginx is installed or not.

Deploy a sample webpage using the ansible-playbook

Create an index.html file on the master server.
Modify the ansible-playbook to transfer the index.html file to the Nginx location.
Run the playbook again.
Enter the public IP address of one of the EC2 instances, it is working fine.
Check another server, it is working on all the servers.
