Running the playbook

There are no changes to our site.yml file, meaning that we just need to run the following command to start the playbook run:

$ ansible-playbook -i production site.yml

This will run through the playbook, giving the following output; please note that I have trimmed a few parts of the playbook output:

PLAY RECAP 
centos : ok=47 changed=37 unreachable=0 failed=0
ubuntu : ok=45 changed=33 unreachable=0 failed=0

Once the playbook has finished, you should be able to access http://192.168.50.6.nip.io/ in your browser, and you should see WordPress showing that it is installed on a Red Hat-based operating system:

Going to http://192.168.50.7.nip.io/ will show the same theme, but it should state that it is running in a Debian-based operating system, as in this screenshot:

You can try rerunning your playbook to see what results are returned, and also you can remove the Vagrant boxes by running:

$ vagrant destroy

You will be asked if you want to remove each machine one at a time; just answer yes to each of the two prompts.
