The following playbook has a single play and runs on all hosts from your inventory file, by default.

If you followed our guide on how to create inventory files, this should be a folder called ansible inside your home directory: This file will be copied from the Ansible control node to the remote nodes in your inventory file.Ĭreate a new file called playbook.yml in the same directory as your inventory file. We’ll set up a testing playbook that installs Nginx and sets up an index.html page on the remote server. To try out the examples described in this guide, you’ll need an Ansible playbook. In case you don’t have a playbook already available to you, you can create a testing playbook as described in the next section. Once you have met these prerequisites, run a connection test as outlined in our guide on How To Manage Multiple Servers with Ansible Ad Hoc Commands to make sure you’re able to connect and execute Ansible instructions on your remote nodes. To set this up, please refer to the guide on How To Set Up Ansible Inventories. Make sure you have a working inventory file containing all your Ansible hosts.

An inventory file set up on the Ansible control node.

To set this up, you can follow Step 2 of How to Set Up SSH Keys on Ubuntu 20.04. This user can be either root or a regular user with sudo privileges.

The Ansible control node’s SSH public key added to the authorized_keys of a system user.

This guide assumes your Ansible hosts are remote Ubuntu 20.04 servers. An Ansible host is any machine that your Ansible control node is configured to automate.

To set up Ansible, please follow our guide on How to Install and Configure Ansible on Ubuntu 20.04. Make sure the control node has a regular user with sudo permissions and a firewall enabled, as explained in our Initial Server Setup guide.

This guide assumes your control node is an Ubuntu 20.04 machine with Ansible installed and configured to connect to your Ansible hosts using SSH keys. In order to follow this guide, you’ll need: This short guide demonstrates how to execute Ansible playbooks to automate server setup, using an example playbook that sets up an Nginx server with a single static HTML page. Playbooks are written in YAML, and can contain one or more plays. While ad hoc commands allow you to run one-off tasks on servers registered within your inventory file, playbooks are typically used to automate a sequence of tasks for setting up services and deploying applications to remote servers. With a minimalist design intended to get users up and running quickly, it allows you to control one to hundreds of systems from a central location with either playbooks or ad hoc commands. Ansible is a modern configuration management tool that facilitates the task of setting up and maintaining remote servers.
