Install and configure controller node for Red Hat Enterprise Linux and CentOS
This section describes how to install and configure the Compute service, code-named nova, on the controller node.
Prerequisites
Before you install and configure the Compute service, you must create databases, service credentials, and API endpoints.
To create the databases, complete these steps:
Use the database access client to connect to the database server as the
rootuser:$ mysql -u root -pCreate the
nova_api,nova, andnova_cell0databases:MariaDB [(none)]> CREATE DATABASE nova_api; MariaDB [(none)]> CREATE DATABASE nova; MariaDB [(none)]> CREATE DATABASE nova_cell0;Grant proper access to the databases:
MariaDB [(none)]> GRANT ALL PRIVILEGES ON nova_api.* TO 'nova'@'localhost' \ IDENTIFIED BY 'NOVA_DBPASS'; MariaDB [(none)]> GRANT ALL PRIVILEGES ON nova_api.* TO 'nova'@'%' \ IDENTIFIED BY 'NOVA_DBPASS'; MariaDB [(none)]> GRANT ALL PRIVILEGES ON nova.* TO 'nova'@'localhost' \ IDENTIFIED BY 'NOVA_DBPASS'; MariaDB [(none)]> GRANT ALL PRIVILEGES ON nova.* TO 'nova'@'%' \ IDENTIFIED BY 'NOVA_DBPASS'; MariaDB [(none)]> GRANT ALL PRIVILEGES ON nova_cell0.* TO 'nova'@'localhost' \ IDENTIFIED BY 'NOVA_DBPASS'; MariaDB [(none)]> GRANT ALL PRIVILEGES ON nova_cell0.* TO 'nova'@'%' \ IDENTIFIED BY 'NOVA_DBPASS';Replace
NOVA_DBPASSwith a suitable password.Exit the database access client.
Source the

Install and configure components
Install the packages:
# yum install openstack-nova-api openstack-nova-conductor \ openstack-nova-console openstack-nova-novncproxy \ openstack-nova-scheduler openstack-nova-placement-apiEdit the
/etc/nova/nova.conffile and complete the following actions:In the
[DEFAULT]section, enable only the compute and metadata APIs:[DEFAULT] # ... enabled_apis = osapi_compute,metadataIn the
[api_database]and[database]sections, configure database access:[api_database] # ... connection = mysql+pymysql://nova:NOVA_DBPASS@controller/nova_api [database] # ... connection = mysql+pymysql://nova:NOVA_DBPASS@controller/novaReplace
NOVA_DBPASSwith the password you chose for the Compute databases.In the
[DEFAULT]section, configureRabbitMQmessage queue access:[DEFAULT] # ... transport_url = rabbit://openstack:RABBIT_PASS@controllerReplace
RABBIT_PASSwith the password you chose for theopenstackaccount inRabbitMQ.In the
[api]and[keystone_authtoken]sections, configure Identity service access:[api] # ... auth_strategy = keystone [keystone_authtoken] # ... auth_uri = http://controller:5000 auth_url = http://controller:35357 memcached_servers = controller:11211 auth_type = password project_domain_name = default user_domain_name = default project_name = service username = nova password = NOVA_PASSReplace
NOVA_PASSwith the password you chose for thenovauser in the Identity service.Note
Comment out or remove any other options in the
[keystone_authtoken]section.In the
[DEFAULT]section, configure themy_ipoption to use the management interface IP address of the controller node:[DEFAULT] # ... my_ip = 10.0.0.11In the
[DEFAULT]section, enable support for the Networking service:[DEFAULT] # ... use_neutron = True firewall_driver = nova.virt.firewall.NoopFirewallDriverNote
By default, Compute uses an internal firewall driver. Since the Networking service includes a firewall driver, you must disable the Compute firewall driver by using the
nova.virt.firewall.NoopFirewallDriverfirewall driver.In the
[vnc]section, configure the VNC proxy to use the management interface IP address of the controller node:[vnc] enabled = true # ... server_listen = $my_ip server_proxyclient_address = $my_ipIn the
[glance]section, configure the location of the Image service API:[glance] # ... api_servers = http://controller:9292In the
[oslo_concurrency]section, configure the lock path:[oslo_concurrency] # ... lock_path = /var/lib/nova/tmpIn the
[placement]section, configure the Placement API:[placement] # ... os_region_name = RegionOne project_domain_name = Default project_name = service auth_type = password user_domain_name = Default auth_url = http://controller:35357/v3 username = placement password = PLACEMENT_PASSReplace
PLACEMENT_PASSwith the password you choose for theplacementuser in the Identity service. Comment out any other options in the[placement]section.Due to a packaging bug, you must enable access to the Placement API by adding the following configuration to
/etc/httpd/conf.d/00-nova-placement-api.conf:<Directory /usr/bin> <IfVersion >= 2.4> Require all granted </IfVersion> <IfVersion < 2.4> Order allow,deny Allow from all </IfVersion> </Directory>Restart the httpd service:
# systemctl restart httpd

Finalize installation
Start the Compute services and configure them to start when the system boots:
# systemctl enable openstack-nova-api.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-consoleauth.service openstack-nova-scheduler.service \ openstack-nova-conductor.service openstack-nova-novncproxy.service
