 Ansible - How to setup Ansible Environment

In my example, I will should you how to setup your ansible environment and run the ping module.

1) I have created 3 Ubuntu servers with the names:-

Server1 - Installed Ansible

Server2 - Client Node1

Server3- Client Node2

Note:- I installed ansible on Server1 by running the below commands on ubuntu:-

sudo apt-add-repository ppa:ansible/ansible

sudo apt update

sudo apt install ansible

Once ansible is installed on the server1, we can check it by running the command:- ansible --version

2) Then I generated ssh-keys on the server1 by running the command:= ssh-keygen -t rsa

3) Then I copied the keygen to all servers by running the command:- ssh-copy-id <IP Address>
For Example:-





This is to make sure, we can run the ansible playbooks from the ansible server. I will be using root user to execute the playbooks.

4) Then I created a folder scripts which will be used for keeping all my playbooks, inventory files etc.

5) Then I created my inventory file in the same folder as inv

I defined hosts in my inv file with 2 groups:- all and app

The all group is having all the 3 hosts - server1, server2 and server3 and the app group is having 2 hosts:- server2 and server3 as shown below

6) I also created a file ansible.cfg in the same folder - scripts and defined the name of my inventory file.
In my example, it is inv

7) Now we can check the connectivity between the servers with the help of ping module.
Command:- ansible -m ping [Name of the group defined in inventory file - inv)
In my example, I am running it on app group 

Now I am running the ping module for the all group defined in the inv file.

The above screenshots refers successfully connectivity between all the servers from the ansible server -server1.
