keystone configuring problem [closed]
I'm installing openstack havana on Ubuntu 12.04 LTS
and I got an err message from openstack
root@controller:~# export OS_SERVICE_ENDPOINT=http://x.x.x.x
root@controller:~# keystone tenant-create --name=admin --description="Admin Tenant"
Unable to communicate with identity service: <title>404 Not Found</title>
Not Found
The requested URL /tenants was not found on this server.
Apache/2.2.22 (Ubuntu) Server at x.x.x.x Port 80 . (HTTP 404)
What's the matter? I only install it only one machine and no virtual machine, and x.x.x.x is controller machine's static ip.
