(2) When the virtual machine is booted, run "vagrant ssh" in the command line to access the guest box;

(3) On the host, type "10.0.33.18" in a web browser to test if Apache is successfully installed and running with the Vagrantfile provisioner "Option 1: Shell";

(4) On the guest, run "ps -ef | grep mongod" and "ps -ef | grep redis" in the command line to test if MongoDB and Redis are successfully installed and running with the Vagrantfile provisioner "Option 2: Puppet";

(5) On the guest, run "exit" to logout the guest box, and on the host, run "vagrant halt" to shut down the guest box.
