Introduction to Ansible

Ansible is an open-source automation tool that simplifies IT orchestration, configuration management, and application deployment. It allows you to automate repetitive tasks, manage infrastructure as code, and streamline complex workflows.

Why Ansible?

Ansible is known for its simplicity and agentless architecture. It uses SSH to connect to servers, making it easy to set up and use. Whether you're managing a small infrastructure or a large-scale deployment, Ansible provides a powerful and flexible solution.


Let's dive into the installation process. Ansible can be installed on various operating systems, including Linux, macOS, and Windows. Here, we'll focus on installing Ansible on a Linux-based system.

Step 1: Update Your System

Before installing Ansible, ensure your system is up to date:

sudo apt update
sudo apt upgrade -y

Step 2: Install Ansible

Install Ansible using your package manager. For Ubuntu/Debian-based systems:

sudo apt install ansible -y

For Red Hat/CentOS-based systems:

sudo yum install ansible -y

Step 3: Verify Installation

Confirm the installation by checking the Ansible version:

ansible --version

You should see output displaying the installed Ansible version.

Basic Configuration and Setup

Now that Ansible is installed, let's perform some basic configuration to get started.

Step 1: Create an Ansible Configuration File

Ansible uses a configuration file (ansible.cfg) to manage settings. Create one in your home directory:

touch ~/.ansible.cfg

Step 2: Configure Ansible

Open ~/.ansible.cfg in a text editor and add the following basic configuration:

inventory = ~/ansible_inventory
remote_user = your_username

Replace your_username with your actual username. This configuration specifies the inventory file location and the default remote user.

Step 3: Create an Inventory File

The inventory file defines the hosts Ansible will manage. Create a simple inventory file (ansible_inventory) in your home directory:

server1 ansible_host=your_server_ip
server2 ansible_host=your_server_ip

Replace your_server_ip with the actual IP addresses of your servers.

Step 4: Test Ansible Connectivity

Ensure Ansible can connect to your servers:

ansible -m ping -i ~/ansible_inventory all

If everything is set up correctly, you should see a successful ping response from your servers.


Congratulations! You've successfully installed Ansible and performed basic configuration. This lays the foundation for automating tasks and managing infrastructure efficiently.

In the next blog post, we'll delve into writing Ansible playbooks and executing ad-hoc commands for more advanced automation.

Stay tuned for more Ansible adventures! ๐Ÿค–โœจ
