Ansible installation and configuration on AWS EC2 instance

This document will help you to install and configuration on AWS EC2 instance. I will install Ansible on the Ansible Control Node and configure SSH access to Ansible Host.

Here, I have used one AWS instance for Ansible control node and one AWS instance for Ansible host. Both servers are using Ubuntu 18.04.

Install Ansible on Ansible control Node

• To update the Ansible control Node, run

sudo apt-get update

• To install software-properties-common. It manages your distribution and independent software vendor software sources.

sudo apt install software-properties-common 

• Add the following ppa(Personal Package Archives) to your System.

sudo apt-add-repository ppa:ansible/ansible

• To update the server, run

sudo apt update 

• To Install ansible, run

sudo apt install ansible

• To check Ansible Version, run

ansible --version

From the Ansible Host,

• To update Ansible Host, run

sudo apt-get update

• To install python, run

sudo apt-get install python

Configure SSH access to Ansible Host (For Keyless SSH)

• From the Ansible control Node, run the below command to generate a private key (id_rsa) and public key (id_rsa.pub)

ssh-keygen

• Copy public-key (id_rsa.pub) and add it to the file .ssh/authorized_keys in the Ansible Host.
• Permission of private key (id_rsa) should be 400.

sudo vi .ssh/authorized_keys

For setting up Ansible Host and testing connection:-

• Add following lines to the file /etc/ansible/hosts

[servers]
host1 ansible_ssh_host=public_ip_of_host 

• Check connectivity to all hosts using the following command.

ansible -m ping all

Output like this :

That’s it 🙂
