Static Inventories Task:
1. Add a new group to your default ansible host file. call the group [ec2]
2. Add a newhost to the new group you created.
3. Add a variable to a new host entry in the /etc/ansible/hosts file. Add the following. localhost http_port=80 maxRequestsPerChild=808
4. Check to see if maxRequestsPerChild is pulled out with an ad-hoccommand.

1. Edit the /etc/ansible/hosts file. Add a group.
2. Edit the /etc/ansible/hosts file. Add a user under the group you created.
3. Edit the /etc/ansible/hosts file. Find a host. if we add a variable called maxRequestsPerChild to the host it would look like this. host1 maxRequestsPerChild=808
4. ansible ec2 -m shell -a "echo {{ maxRequestsPerChild }}"
5. Edit a local file. It could be called anything. Lets call it myhosts. Inside the file it would have a host like the following. [mygroup] myusername1.mylabserver.com
