# Export OS _SERVICE_TIOEN = 02456f17dc198d827a90

# Export OS _SERVICE_ENDPOINT = http: // controller: 35357/v2.0

Create the admin tenant:

# Keystone tenant-create -- name admin -- description "Admin Tenant"

Create the admin user:

# Keystone user-create -- name admin -- pass test01 -- email admin@test.com

Create the admin role:

# Keystone role-create -- name admin

Add the admin role to the admin tenant and user:

# Keystone user-role-add -- user admin -- tenant admin -- role admin

Create a demo tenant and user for typical operations in your environment:

Create the demo tenant:

# Keystone tenant-create -- name demo -- description "Demo Tenant"

Create the demo user under the demo tenant:

# Keystone user-create -- name demo -- tenant demo -- pass test01 -- email admin@test.com

Create the service tenant:

# Keystone tenant-create -- name service -- description "Service Tenant"

Create the service entity for the Identity service:

# Keystone service-create -- name keystone -- type identity -- description "Openstack Identity"

Create the Identity service API endpoints:

# Keystone endpoint-create -- service-id $ (keystone service-list | awk '/identity/{print $2}') -- publicurl http: // controller: 5000/v2.0 -- internalurl http: // controller: 5000/v2.0 -- adminurl http: // controller: 35357/v2.0 -- region regionOne
