Running the role
Now that the role for installing and configuring Apache is complete, we can add it to our playbook:
---
- hosts: boxes
gather_facts: true
become: yes
become_method: sudo
vars_files:
- group_vars/common.yml
roles:
- roles/common
- roles/apache
Following on from the playbook in the previous section, we can simply rerun the following command:
$ ansible-playbook -i production site.yml
This will work through the common role before executing the apache role. I have truncated the output for the common role in the playbook run here:

Opening http://192.168.50.4.nip.io/ in our browser should give us a page that looks like the following screenshot:
As you can see, the template has picked up all of the variables we defined; the source for the page looks like this:
<!--Ansible managed-->
<!doctype html>
<title>Success !!!</title>
<style>
body { text-align: center; padding: 150px; }
h1 { font-size: 50px; }
body { font: 20px Helvetica, sans-serif; color: #333; }
article { display: block; text-align: left; width: 650px;
margin: 0 auto; }
</style>
<article>
<h1>Success !!!</h1>
<p>
<p>This HTML page has been deployed using Ansible to
<b>192.168.50.4.nip.io</b>.<br>
The user is <b>lamp</b> who is in the <b>apache</b> group.<br>
The weboot is <b>/home/lamp/web</b>, the default index file is
<b>index.html</b>.<br></p>
</p>
</article>
If we were to rerun the playbook, we should see the following results:
PLAY RECAP *****************************************************************************************
box : ok=14 changed=0 unreachable=0 failed=0
As you can see, there are 14 tasks that are ok, and nothing has changed.
