☁️ Lets setup the environment in AWS

• We will spin up one EC2 as slave and one EC2 as the Master Node or the control center for ansible.
• Then we use this Master node to connect the other EC2 instance (Slave).

🪛 Prerequsite

• Access and privilages to launch EC2 with Ubuntu
• Putty or any other SSH tools
• Security group with ports ssh open (Port 22)

Setup environment

Lets launch 2 EC2 instances

• Use AWS EC2 console or CLI.

aws ec2 run-instances \
--image-id <ami-id> \
--instance-type <instance-type> \
--subnet-id <subnet-id> \
--security-group-ids <security-group-id>\
--key-name <ec2-key-pair-name> \
--count 2

Set up Ansible Control Center

• Rename one EC2 to Ansible Control Center on console
• Now lets SSH into Ansible Control Center EC2
  • Rename the server

   sudo hostnamectl set-hostname Ansible-Control-Center

• Now lets update and install ANSIBLE

Run these commands

sudo apt-get update
sudo apt install software-properties-common -y
sudo apt-add-repository ppa:ansible/ansible
sudo apt update
sudo apt install ansible -y 

Set up Ansible Slaves – Your ProdServer

• Rename one EC2 to Ansible Slaves – Your ProdServer on console
• Rename the server

   sudo hostnamectl set-hostname AnsibleSlaves-YourProdServer

• Install Python

  sudo apt-get update
  sudo apt-get install python3 -y

Configure SSH access

On Ansible Control Center

• Genarate a rsa key.

cd .ssh
ssh-keygen

• Press enter ,we donot require any changes.
  
• Now if we ls we will be able to see id_rsa & id_rsa.pub, lets cat id_rsa.pub.

cat id_rsa.pub

Note down this key

On Ansible Slaves

• ssh into your slave server then,

cd .ssh
sudo nano authorized_keys

• Now on next line paste the key we previously noted & save it.

Now its play time.

Goto your Ansible Control Center EC2.

• lets ssh into ansible slave
