== 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/
+

=== Configure nova to use keystone ===
+
 
+
* Change nova configuration to use keystone:
+
$> sudo sed -i -e 's/# \(pipeline = .*\keystonecontext\)/\1/g' /etc/nova/api-paste.ini
+
$> 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

+
=== Configure glance to use keystone ===
+
 
+
* Tell keystone about the glance service
+
$> cat << EOF | sudo tee -a /etc/keystone/default_catalog.templates                                                     
+
catalog.RegionOne.image.publicURL = http://localhost:9292/v1
+
catalog.RegionOne.image.adminURL = http://localhost:9292/v1
+
catalog.RegionOne.image.internalURL = http://localhost:9292/v1
+
catalog.RegionOne.image.name = 'Image Service'
+
EOF
+
$> sudo systemctl restart openstack-keystone
+
 
+
* Change glance configuration to use keystone:
+
$> echo -e "\nw[paste_deploy]\nflavor = keystone" | sudo tee -a /etc/glance/glance-api.conf
+
$> echo -e "\nw[paste_deploy]\nflavor = keystone" | sudo tee -a /etc/glance/glance-registry.conf
+
$> sudo openstack-config-set /etc/glance/glance-api-paste.ini filter:authtoken admin_token $ADMIN_TOKEN
+
$> sudo openstack-config-set /etc/glance/glance-registry-paste.ini filter:authtoken admin_token $ADMIN_TOKEN
+
$> sudo systemctl restart openstack-glance-api.service
+
$> sudo systemctl restart openstack-registry-api.service
+
 
+
* Verify that glance can talk with keystone (required variable exports from keystone section)
+
 
+
$> glance index
+
 
+
 
+
== Configuring the OpenStack Dashboard ==
+
 
+
The OpenStack dashboard is the official web user interface for OpenStack. It should mostly work out of the box, as long as keystone has been configured properly.
+
 
+
* Install the dashboard
+
$> sudo yum install openstack-dashboard
+
 
+
* Make sure httpd is running
+
$> sudo systemctl restart httpd
+
$> sudo systemctl enable httpd
+
 
+
The dashboard should then be accessed with a web browser at http://localhost . Account and password should be
+
what you configured for the keystone setup.
+
