[Openstack] Questions from a newbie

Hi Chen,
I've tried to put HOST_IP=127.0.0.1 and to re-execute ./stack.sh (I've
previously removed the folder /opt/stack and done ./clean.sh).
But this gave me an error:

WARNING: urllib3.connectionpool Connection pool is full, discarding
connection: 127.0.0.1
ERROR: openstack 410 Gone: Error in store configuration. Adding images to
store is disabled. (HTTP N/A)

and I can't complete the installation.
Have you got any idea to solve it?

This is the local.conf that I've used:

[[local|localrc]]
ADMIN_PASSWORD=stack
DATABASE_PASSWORD=$ADMIN_PASSWORD
RABBIT_PASSWORD=$ADMIN_PASSWORD
SERVICE_PASSWORD=$ADMIN_PASSWORD
SERVICE_TOKEN=a682f596-76f3-11e3-b3b2-e716f9080d50
HOST_IP=127.0.0.1

Thanks
