Here’s a simple playbook that sets up an Apache web server on a RHEL/CentOS 7 box:

Here’s a breakdown of what the above yaml syntax shows. At the top level is a single item list. This list item houses a hash with 3 key-value pairs. The first to key’s values are of the type string. However the third key’s (tasks) houses a list of 4 items. Each one of these list items contains a hash. Each of these hashes is made up of 2 key-value pairs.
Now let’s run this playbook:
[root@controller playbooks]# pwd /root/playbooks [root@controller playbooks]# ls httpd.yaml $ ansible-playbook httpd.yml
We can test if this has worked, by opening to http://ansibleclient01.local in your web browser.
