* 2. Use an ad-hoc ansible command, find the free space of your servers.
* 3. Use an ad-hoc ansible command, find out the memory usage of your servers.
* 4. Do an ls -l on the targets /var/log/messages file.
* 5. Tail the contents of the targets /var/log/messages file.

Using the Simulation Program, perform the following tasks:
Static Inventories Task:
* 1. Add a new group to your default ansible host file. call the group [ec2]
* 2. Add a new host 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-hoc command.
* 5. Create a local host file and put a target group and then a host into it. Then ping it with an ad-hoc command.
Solution:
* 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
