This section describes how to install and configure the Compute service, code-named nova, on the controller node. Before you install and configure the Compute service, you must create a database, service credentials, and API endpoint. To create the database, complete these steps: Use the database access client to connect to the database server as the root user: $ mysql -u root -p Create the nova database: CREATE DATABASE nova; Grant proper access to the nova database: GRANT ALL PRIVILEGES ON nova.* TO 'nova'@'localhost' \ IDENTIFIED BY 'NOVA_DBPASS'; GRANT ALL PRIVILEGES ON nova.* TO 'nova'@'%' \ IDENTIFIED BY 'NOVA_DBPASS'; Replace NOVA_DBPASS with a suitable password. Exit the database access client. Source the admin credentials to gain access to admin-only CLI commands: $ source admin-openrc.sh To create the service credentials, complete these steps: Create the nova user: $ openstack user create --password-prompt nova User Password: Repeat User Password: +----------+----------------------------------+ | Field | Value | +----------+----------------------------------+ | email | None | | enabled | True | | id | 8e0b71d732db4bfba04943a96230c8c0 | | name | nova | | username | nova | +----------+----------------------------------+ Add the admin role to the nova user: $ openstack role add --project service --user nova admin +-------+----------------------------------+ | Field | Value | +-------+----------------------------------+ | id | cd2cb9a39e874ea69e5d4b896eb16128 | | name | admin | +-------+----------------------------------+ Create the nova service entity: $ openstack service create --name nova \ --description "OpenStack Compute" compute +-------------+----------------------------------+ | Field | Value | +-------------+----------------------------------+ | description | OpenStack Compute | | enabled | True | | id | 060d59eac51b4594815603d75a00aba2 | | name | nova | | type | compute | +-------------+----------------------------------+ Create the Compute service API endpoint: $ openstack endpoint create \ --publicurl http://controller:8774/v2/%\(tenant_id\)s \ --internalurl http://controller:8774/v2/%\(tenant_id\)s \ --adminurl http://controller:8774/v2/%\(tenant_id\)s \ --region RegionOne \ compute +--------------+-----------------------------------------+ | Field | Value | +--------------+-----------------------------------------+ | adminurl | http://controller:8774/v2/%(tenant_id)s | | id | 4e885d4ad43f4c4fbf2287734bc58d6b | | internalurl | http://controller:8774/v2/%(tenant_id)s | | publicurl | http://controller:8774/v2/%(tenant_id)s | | region | RegionOne | | service_id | 060d59eac51b4594815603d75a00aba2 | | service_name | nova | | service_type | compute | +--------------+-----------------------------------------+ Default configuration files vary by distribution. You might need to add these sections and options rather than modifying existing sections and options. Also, an ellipsis (...) in the configuration snippets indicates potential default configuration options that you should retain. Install the packages: # apt-get install nova-api nova-cert nova-conductor nova-consoleauth \ nova-novncproxy nova-scheduler python-novaclient # yum install openstack-nova-api openstack-nova-cert openstack-nova-conductor \ openstack-nova-console openstack-nova-novncproxy openstack-nova-scheduler \ python-novaclient # zypper install openstack-nova-api openstack-nova-scheduler openstack-nova-cert \ openstack-nova-conductor openstack-nova-consoleauth openstack-nova-novncproxy \ python-novaclient iptables Edit the /etc/nova/nova.conf file and complete the following actions: Add a [database] section, and configure database access: [database] ... connection = mysql://nova:NOVA_DBPASS@controller/nova Replace NOVA_DBPASS with the password you chose for the Compute database. In the [DEFAULT] and [oslo_messaging_rabbit] sections, configure RabbitMQ message queue access: [DEFAULT] ... rpc_backend = rabbit [oslo_messaging_rabbit] ... rabbit_host = controller rabbit_userid = openstack rabbit_password = RABBIT_PASS Replace RABBIT_PASS with the password you chose for the openstack account in RabbitMQ. In the [DEFAULT] and [keystone_authtoken] sections, configure Identity service access: [DEFAULT] ... auth_strategy = keystone [keystone_authtoken] ... auth_uri = http://controller:5000 auth_url = http://controller:35357 auth_plugin = password project_domain_id = default user_domain_id = default project_name = service username = nova password = NOVA_PASS Replace NOVA_PASS with the password you chose for the nova user in the Identity service. Comment out or remove any other options in the [keystone_authtoken] section. In the [DEFAULT] section, configure the my_ip option to use the management interface IP address of the controller node: [DEFAULT] ... my_ip = 10.0.0.11 In the [DEFAULT] section, configure the VNC proxy to use the management interface IP address of the controller node: [DEFAULT] ... vncserver_listen = 10.0.0.11 vncserver_proxyclient_address = 10.0.0.11 In the [glance] section, configure the location of the Image service: [glance] ... host = controller In the [oslo_concurrency] section, configure the lock path: [oslo_concurrency] ... lock_path = /var/lib/nova/tmp [oslo_concurrency] ... lock_path = /var/run/nova (Optional) To assist with troubleshooting, enable verbose logging in the [DEFAULT] section: [DEFAULT] ... verbose = True Populate the Compute database: # su -s /bin/sh -c "nova-manage db sync" nova Install the packages: # apt-get install nova-api nova-cert nova-conductor nova-consoleauth \ nova-novncproxy nova-scheduler python-novaclient Respond to prompts for database management, Identity service credentials, service endpoint registration, and message queue credentials. Edit the /etc/nova/nova.conf file and complete the following actions: In the [DEFAULT] section, configure the VNC proxy to use the management interface IP address of the controller node: [DEFAULT] ... vncserver_listen = 10.0.0.11 vncserver_proxyclient_address = 10.0.0.11 Restart the Compute services: # service nova-api restart # service nova-cert restart # service nova-consoleauth restart # service nova-scheduler restart # service nova-conductor restart # service nova-novncproxy restart Start the Compute services and configure them to start when the system boots: # systemctl enable openstack-nova-api.service openstack-nova-cert.service \ openstack-nova-consoleauth.service openstack-nova-scheduler.service \ openstack-nova-conductor.service openstack-nova-novncproxy.service # systemctl start openstack-nova-api.service openstack-nova-cert.service \ openstack-nova-consoleauth.service openstack-nova-scheduler.service \ openstack-nova-conductor.service openstack-nova-novncproxy.service By default, the Ubuntu packages create an SQLite database. Because this configuration uses a SQL database server, you can remove the SQLite database file: # rm -f /var/lib/nova/nova.sqlite
