How to Configure Ansible Managed Nodes and Run ad-hoc Commands – Part 3
Ravi SaiveOctober 25, 2019 CategoriesAnsible Leave a comment

In the previous two articles of this Ansible Series, we’ve explained Core Components of Ansible and Setting Up Ansible Control Node. In this part 3, we will demonstrate how you can configure Ansible managed nodes to run ad-hoc commands on remote hosts.

Setup Passwordless SSH Authentication to Ansible Managed Nodes
As a recap on our last topic, managing remote hosts with Ansible requires setting up of Passwordless SSH authentication between the Ansible control node and the managed hosts. This involves the generation of a key pair (Public and Private SSH key pair) on the Ansible Control node and copying the Public key to all of the remote hosts. This will be a crucial step going forward and will make your work much easier.
