First of all, let's launch the CentOS 7 Vagrant box by running one of the following commands:
$ vagrant up
$ vagrant up --provider=vmware_fusion
Now that we have our server, we need to update the host inventory; in the production file, enter the following:
box ansible_host=192.168.50.4.nip.io
[boxes]
box
[boxes:vars]
ansible_connection=ssh
ansible_user=vagrant
ansible_private_key_file=~/.ssh/id_rsa
host_key_checking=False
Finally, we need something that will execute our role. Add the following content to the site.yml file:
---
- hosts: boxes
gather_facts: true
become: yes
become_method: sudo
vars_files:
- group_vars/common.yml
roles:
- roles/common
Now that we have our playbook file ready, we can run it against our Vagrant box by running:
$ ansible-playbook -i production site.yml
After a few minutes, you should see something similar to the following output:

As you can see, we have skipped the task which restarts NTP and there are no additional packages or updates to install, nor are there any changes to the user or group we created. Now that we have our basic packages updated and installed, and our base operating system configured, we are ready to install Apache.
