Ansible is an open source automation platform used for configuration management, application deployment and task automation. It allows users to easily manage complex infrastructure and applications in an efficient and secure manner.

Requirements

Before setting up Ansible, make sure the following components are installed:

• Python 2.7 or later
• SSH
• Python libraries

Setting Up Ansible

Installing Ansible

1. Start by using the package manager of your operating system to install Ansible. For example, if you are using an Ubuntu-based distribution, you can use the following command:

$ sudo apt install ansible

2. Verify the version of Ansible installed:

$ ansible --version

Configuring Ansible

1. Create a configuration file for Ansible, usually called ansible.cfg in the /etc/ansible directory. This file will contain the settings for Ansible.
2. Set up the inventory file, which is a list of hosts that Ansible will manage. This file is usually called hosts and is located in the /etc/ansible directory.
3. Create an SSH key pair for authentication. This can be done with the following command:

$ ssh-keygen

4. Copy the public key to the hosts you want to manage with Ansible. This can be done with the following command:

$ ssh-copy-id user@host

Conclusion

By following the steps outlined above, you should now be able to set up Ansible and use it to manage your infrastructure and applications.
