Configuring keystone for authentication

Keystone is the openstack identity service, providing a central place to set up openstack users, groups, and accounts that can be shared across all other services. This deprecates the old style user accounts manually set up with nova-manage.

Setting up keystone is required for using the Openstack dashboard.

Initial setup

  • install Keystone
$> sudo yum install --enablerepo=updates-testing openstack-keystone python-keystoneclient

Should get installed:

python-keystoneclient >= 2012.1-0.5.e4
openstack-keystone >= 2012.1-0.9.e4
  • configure Keystone database
$> sudo openstack-keystone-db-setup
Please enter the password for the 'root' MySQL user: 
Verified connectivity to MySQL.
Creating 'keystone' database.
Asking openstack-keystone to sync the databse.
Complete!
  • change default administrative token in keystone.conf
$> ADMIN_TOKEN=$(openssl rand -hex 10)
$> sudo openstack-config-set /etc/keystone/keystone.conf DEFAULT admin_token $ADMIN_TOKEN
  • start and enable Keystone service
$> sudo systemctl start openstack-keystone.service
$> sudo systemctl enable openstack-keystone.service
  • create sample Tenants, Users and Roles
$> sudo ADMIN_PASSWORD=verybadpass openstack-keystone-sample-data
  • test Keystone CLI is working
export OS_USERNAME=admin
export OS_PASSWORD=verybadpass
export OS_TENANT_NAME=admin
export OS_AUTH_URL=http://127.0.0.1:5000/v2.0/
keystone user-list

$> sudo openstack-config-set /etc/nova/api-paste.ini filter:authtoken admin_token $ADMIN_TOKEN
$> sudo systemctl restart openstack-nova-api.service
  • Verify that nova can talk with keystone (required variable exports from keystone section)
$> nova --version 1.1 flavor-list
+----+-----------+-----------+------+----------+-------+-------------+
| ID |    Name   | Memory_MB | Swap | Local_GB | VCPUs | RXTX_Factor |
