Open Stack

Hello,

I am trying to install Openstack *liberty* version on *Centos7*.
I am stucked while installing Identity service creation. I have searched
google for the solution but could not find one!

My admin-openrc.sh contains:
export OS_PROJECT_DOMAIN_ID=default
export OS_USER_DOMAIN_ID=default
export OS_PROJECT_NAME=os_demo
export OS_TENANT_NAME=admin
export OS_USERNAME=admin
export OS_PASSWORD=password
export OS_AUTH_URL=http://controller:35357/v3 <http://10.0.0.11:35357/v3>
export OS_IDENTITY_API_VERSION=3
export OS_IMAGE_API_VERSION=2

Command tried is:
# openstack service create --name keystone --description "OpenStack
Identity" identity --os-username admin --os-auth-url
http://controller:35357/v3 <http://10.0.0.11:35357/v3> --os-project-name
os_demo
Output-->
*Discovering versions from the identity service failed when creating the
password plugin. Attempting to determine version from URL.*
*Internal Server Error (HTTP 500)*

When I check the file /var/log/httpd/keystone-error.log, I noticed these
lines:
mod_wsgi (pid=56573): Target WSGI script '/usr/bin/keystone-wsgi-admin'

Please help me get out of this issue.

I have other queries mentioned below:
1. I see an example of 2-node architecture in the installation guide for
liberty version. Which guide do I have to refer to have 3-node architecture
(Node1 being Controller, Node2 as Nuetron and Node3 as a compute)?

Thanks,
Basavaraj
