Solution
Prerequisites
This assumes you have installed Ansible and configured a managed node to work with it. If you need assistance with this, see this posting.

Procedures
1. On the Ansible control server, create this .yaml file (e.g., called good.yaml):

- hosts: all
  tasks:
  - name: Install Apache web server and nmap
    yum:
      name: "{{ packages }}"
    vars:
      packages:
        - httpd
        - nmap
    become: yes
