To create the components that control the Block Storage Service, complete the following steps on the controller node. You can configure OpenStack to use various storage systems. The examples in this guide show you how to configure LVM. Install the appropriate packages for the Block Storage Service: # apt-get install cinder-api cinder-scheduler # yum install openstack-cinder openstack-utils openstack-selinux # zypper install openstack-cinder-api openstack-cinder-scheduler Respond to the prompts for database management, [keystone_authtoken] settings, RabbitMQ credentials and API endpoint registration. The Block Storage Service stores volume information in a database. The examples in this section use the MySQL database that is used by other OpenStack services. Configure the Block Storage Service to use the database. Replace CINDER_DBPASS with a password of your choosing. # openstack-config --set /etc/cinder/cinder.conf \ database connection mysql://cinder:CINDER_DBPASS@controller/cinder Edit /etc/cinder/cinder.conf and change the [database] section. [database] ... # The SQLAlchemy connection string used to connect to the # database (string value) connection = mysql://cinder:CINDER_DBPASS@localhost/cinder ... To create the Block Storage Service database and tables and a cinder database user, run the openstack-db command. # openstack-db --init --service cinder --password CINDER_DBPASS Use the password that you set to log in as root to create a cinder database. # mysql -u root -p mysql> CREATE DATABASE cinder; mysql> GRANT ALL PRIVILEGES ON cinder.* TO 'cinder'@'localhost' \ IDENTIFIED BY 'CINDER_DBPASS'; mysql> GRANT ALL PRIVILEGES ON cinder.* TO 'cinder'@'%' \ IDENTIFIED BY 'CINDER_DBPASS'; Create the database tables for the Block Storage Service. # cinder-manage db sync Create a cinder user. The Block Storage Service uses this user to authenticate with the Identity Service. Use the service tenant and give the user the admin role. # keystone user-create --name=cinder --pass=CINDER_PASS --email=cinder@example.com # keystone user-role-add --user=cinder --tenant=service --role=admin Add the credentials to the file /etc/cinder/api-paste.ini. Open the file in a text editor and locate the section [filter:authtoken]. Set the following options: [filter:authtoken] paste.filter_factory=keystoneclient.middleware.auth_token:filter_factory auth_host=controller auth_port = 35357 auth_protocol = http admin_tenant_name=service admin_user=cinder admin_password=CINDER_PASS Register the Block Storage Service with the Identity Service so that other OpenStack services can locate it. Register the service and specify the endpoint using the keystone command. # keystone service-create --name=cinder --type=volume \ --description="Cinder Volume Service" Note the id property returned and use it to create the endpoint. # keystone endpoint-create \ --service-id=the_service_id_above \ --publicurl=http://controller:8776/v1/%\(tenant_id\)s \ --internalurl=http://controller:8776/v1/%\(tenant_id\)s \ --adminurl=http://controller:8776/v1/%\(tenant_id\)s Also register a service and endpoint for version 2 of the Block Storage Service API. # keystone service-create --name=cinder --type=volumev2 \ --description="Cinder Volume Service V2" Note the id property returned and use it to create the endpoint. # keystone endpoint-create \ --service-id=the_service_id_above \ --publicurl=http://controller:8776/v2/%\(tenant_id\)s \ --internalurl=http://controller:8776/v2/%\(tenant_id\)s \ --adminurl=http://controller:8776/v2/%\(tenant_id\)s Restart the cinder service with its new settings: # service cinder-scheduler restart # service cinder-api restart Start the cinder services and configure them to start when the system boots. # service openstack-cinder-api start # service openstack-cinder-scheduler start # chkconfig openstack-cinder-api on # chkconfig openstack-cinder-scheduler on
