* Removing public ip doesn't work. Have to modify subnet and recreate the vm:
** Terminate www, rename it to www-deleted.
** Modify subnet to not auto-assign public IPs.
** Recreate the www instance with the same steps, except specify a primary ip.
** Install httpd, php
** To get yum install to work, allocate a new elastic ip "temporary" and associate with www
** Note that www-data was not deleted when the original www was terminated. Attach it to www now.
** All the data on the logical volume is still there, but fstab is gone, add lv-www back into there.
** Start httpd, everything should be back to as it was.
** Dissasociate the public ip. Everything should keep working.
