Cinder – Block storage service – Controller node

Compute nodes will also be used as storage nodes. However we need to install the services in controller node.

Create the database, grant privileges

CREATE DATABASE cinder;

GRANT ALL PRIVILEGES ON cinder.* TO 'cinder'@'localhost' IDENTIFIED BY 'commonpass';

GRANT ALL PRIVILEGES ON cinder.* TO 'cinder'@'%' IDENTIFIED BY 'commonpass';

FLUSH PRIVILEGES;

exit

Create service credentials

. admin-openrc
openstack user create --domain default --password-prompt cinder

openstack role add --project service --user cinder admin

Create the cinderv2 and cinderv3 service entities

openstack service create --name cinderv2 --description "OpenStack Block Storage" volumev2

openstack service create --name cinderv3 --description "OpenStack Block Storage" volumev3

Create service endpoints

openstack endpoint create --region RegionOne volumev2 public http://controller:8776/v2/%\(project_id\)s

openstack endpoint create --region RegionOne volumev2 internal http://controller:8776/v2/%\(project_id\)s

openstack endpoint create --region RegionOne volumev2 admin http://controller:8776/v2/%\(project_id\)s

openstack endpoint create --region RegionOne volumev3 public http://controller:8776/v3/%\(project_id\)s

openstack endpoint create --region RegionOne volumev3 internal http://controller:8776/v3/%\(project_id\)s

openstack endpoint create --region RegionOne volumev3 admin http://controller:8776/v3/%\(project_id\)s

Install the packages

apt install -y cinder-api cinder-scheduler

Update configurations – Edit /etc/cinder/cinder.conf

[database]
connection = mysql+pymysql://cinder:commonpass@controller/cinder

#[DEFAULT] - Added to existing configuration
[DEFAULT]
transport_url = rabbit://openstack:commonpass@controller
auth_strategy = keystone
# Management IP address
my_ip = 10.1.1.60

# Added this section
[keystone_authtoken]
www_authenticate_uri = http://controller:5000
auth_url = http://controller:5000
memcached_servers = controller:11211
auth_type = password
project_domain_name = default
user_domain_name = default
project_name = service
username = cinder
password = commonpass

# Added this section
[oslo_concurrency]
lock_path = /var/lib/cinder/tmp

Populate the database

su -s /bin/sh -c "cinder-manage db sync" cinder

Configure Compute to use Block Storage – Edit /etc/nova/nova.conf

[cinder]
os_region_name = RegionOne

Restart the Compute API and block storage service

service nova-api restart
service cinder-scheduler restart
service apache2 restart
