Doug Hellmann c7bfdbb44f split install guide into separate files by OS 
Provide a script for interpreting the "only" directives and splitting
the existing content up into standalone files for each OS to make it
easier for project teams to copy the parts they need into their own
project documentation trees without requiring separate platform builds.

The files have been hand-edited to pass the niceness check and to allow
the install guide to build.

The script for building the guide has been changed to not build separate
copies per OS.

Install and configure controller node

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.

  1. To create the databases, 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_api, nova, and nova_cell0 databases:

      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_DBPASS with a suitable password.

    • Exit the database access client.

  1. Source the admin credentials to gain access to admin-only CLI commands:

    $ . admin-openrc

  2. Create the Compute service credentials:

    • Create the nova user:

      $ openstack user create --domain default --password-prompt nova

User Password:
Repeat User Password:
+---------------------+----------------------------------+
| Field               | Value                            |
+---------------------+----------------------------------+
| domain_id           | default                          |
| enabled             | True                             |
| id                  | 8a7dbf5279404537b1c7b86c033620fe |
| name                | nova                             |
| options             | {}                               |
| password_expires_at | None                             |
+---------------------+----------------------------------+

    • Add the admin role to the nova user:

      $ openstack role add --project service --user nova admin

      Note

      This command provides no output.

    • 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                          |
+-------------+----------------------------------+

  3. Create the Compute API service endpoints:

    $ openstack endpoint create --region RegionOne \
  compute public http://controller:8774/v2.1

+--------------+-------------------------------------------+
| Field        | Value                                     |

| url          | http://controller:8774/v2.1               |
+--------------+-------------------------------------------+

  4. Create a Placement service user using your chosen PLACEMENT_PASS:

    $ openstack user create --domain default --password-prompt placement

User Password:
Repeat User Password:
+---------------------+----------------------------------+
| Field               | Value                            |
+---------------------+----------------------------------+
| domain_id           | default                          |

| password_expires_at | None                             |
+---------------------+----------------------------------+

  5. Add the Placement user to the service project with the admin role:

    $ openstack role add --project service --user placement admin

    Note

    This command provides no output.

  6. Create the Placement API entry in the service catalog:

Install and configure components

  1. Install the packages:

    # apt install nova-api nova-conductor nova-consoleauth \
  nova-consoleproxy nova-scheduler

    Note

    nova-api-metadata is included in the nova-api package, and can be selected through debconf.

    Note

    A unique nova-consoleproxy package provides the nova-novncproxy, nova-spicehtml5proxy, and nova-xvpvncproxy packages. To select packages, edit the /etc/default/nova-consoleproxy file or use the debconf interface. You can also manually edit the /etc/default/nova-consoleproxy file, and stop and start the console daemons.

  2. Edit the /etc/nova/nova.conf file and complete the following actions:

    • In 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/nova

      Replace NOVA_DBPASS with the password you chose for the Compute databases.

    • In the [DEFAULT] section, configure RabbitMQ message queue access:

      [DEFAULT]
# ...
transport_url = rabbit://openstack:RABBIT_PASS@controller

      Replace RABBIT_PASS with the password you chose for the openstack account in RabbitMQ.

    • 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_PASS

      Replace NOVA_PASS with the password you chose for the nova user in the Identity service.

      Note

      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 [vnc] section, configure the VNC proxy to use the management interface IP address of the controller node:

    [vnc]
enabled = true
# ...
vncserver_listen = $my_ip
vncserver_proxyclient_address = $my_ip

  • In the [spice] section, disable spice:

    [spice]
enabled = false

  • In the [glance] section, configure the location of the Image service API:

    [glance]
# ...
api_servers = http://controller:9292

  • In 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_PASS

    Replace PLACEMENT_PASS with the password you choose for the placement user in the Identity service. Comment out any other options in the [placement] section.

  1. Populate the nova-api database:

    # su -s /bin/sh -c "nova-manage api_db sync" nova

    Note

    Ignore any deprecation messages in this output.

  2. Register the cell0 database:

    # su -s /bin/sh -c "nova-manage cell_v2 map_cell0" nova

  3. Create the cell1 cell:

    # su -s /bin/sh -c "nova-manage cell_v2 create_cell --name=cell1 --verbose" nova
109e1d4b-536a-40d0-83c6-5f121b82b650

  4. Populate the nova database:

    # su -s /bin/sh -c "nova-manage db sync" nova

  5. Verify nova cell0 and cell1 are registered correctly:

    # nova-manage cell_v2 list_cells
+-------+--------------------------------------+
| Name  | UUID                                 |
+-------+--------------------------------------+
| cell1 | 109e1d4b-536a-40d0-83c6-5f121b82b650 |
| cell0 | 00000000-0000-0000-0000-000000000000 |
+-------+--------------------------------------+

Finalize installation

  • Shutdown nova-spicehtml5proxy:

    # service nova-spicehtml5proxy stop

  • Select novnc startup in /etc/default/nova-consoleproxy:

    NOVA_CONSOLE_PROXY_TYPE=novnc

  • Add a systemd service file for nova-novncproxy in /lib/systemd/system/nova-novncproxy.service:

    [Unit]
Description=OpenStack Compute NoVNC proxy
