Chris Dent f21b07153d Remove placement from nova install docs

In a fairly hack and slash fashion, remove the installation of placement
from the nova install docs. Placement will have its own installation
docs.

Configuring access to placement from the controller and compute nodes is
still described.

The depends-on is to the patch that provides placement install docs.

The output of 'nova-status upgrade check' is updated to reflect the
current state of the output of that command; this means it now
includes a fair bit more than checking cells v2 and the existence
of the placement API.

Depends-On: https://review.openstack.org/#/c/628220/

Install and configure controller node for openSUSE and SUSE Linux Enterprise

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 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.

Source the admin credentials to gain access to admin-only CLI commands:
```
$ . admin-openrc
```

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                          |

| 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                            |

| name        | nova                             |
| type        | compute                          |
+-------------+----------------------------------+

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

Install and configure components

Note

As of the Newton release, SUSE OpenStack packages are shipped with the upstream default configuration files. For example, /etc/nova/nova.conf has customizations in /etc/nova/nova.conf.d/010-nova.conf. While the following instructions modify the default configuration file, adding a new file in /etc/nova/nova.conf.d achieves the same result.

Install the packages:

Note

nova-consoleauth is deprecated since 18.0.0 (Rocky) and will be removed in an upcoming release. Console proxies should be deployed per cell. If performing a fresh install (not an upgrade), then you likely do not need to install the nova-consoleauth service. See :oslo.configworkarounds.enable_consoleauth for details.
```
# zypper install openstack-nova-api openstack-nova-scheduler \
  openstack-nova-conductor openstack-nova-consoleauth \
  openstack-nova-novncproxy iptables
```
Edit the /etc/nova/nova.conf file and complete the following actions:
- In the [DEFAULT] section, enable only the compute and metadata APIs:
```
[DEFAULT]
# ...
enabled_apis = osapi_compute,metadata
```
- 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_url = http://controller:5000/v3
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 [DEFAULT] section, enable support for the Networking service:
```
[DEFAULT]
# ...
use_neutron = true
firewall_driver = nova.virt.firewall.NoopFirewallDriver
```
  Note
  
  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.NoopFirewallDriver firewall driver.
- Configure the [neutron] section of /etc/nova/nova.conf. Refer to the Networking service install guide <install/controller-install-obs.html#configure-the-compute-service-to-use-the-networking-service> for more details.
- 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_ip
```
- In the [glance] section, configure the location of the Image service API:
```
[glance]
# ...
api_servers = http://controller:9292
```
- In the [oslo_concurrency] section, configure the lock path:
```
[oslo_concurrency]
# ...
lock_path = /var/run/nova
```
- In the [placement] section, configure access to the Placement service:
```
[placement]
# ...
region_name = RegionOne
project_domain_name = Default
project_name = service
auth_type = password
user_domain_name = Default
auth_url = http://controller:5000/v3
username = placement
password = PLACEMENT_PASS
```
  Replace PLACEMENT_PASS with the password you choose for the placement service user created when installing Placement <install/>. Comment out or remove any other options in the [placement] section.
Populate the nova-api database:
```
# su -s /bin/sh -c "nova-manage api_db sync" nova
```
Note

Ignore any deprecation messages in this output.

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

Create the cell1 cell:

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

Populate the nova database:

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

Verify nova cell0 and cell1 are registered correctly:

# su -s /bin/sh -c "nova-manage cell_v2 list_cells" nova
+-------+--------------------------------------+
| Name  | UUID                                 |
+-------+--------------------------------------+
| cell1 | 109e1d4b-536a-40d0-83c6-5f121b82b650 |
| cell0 | 00000000-0000-0000-0000-000000000000 |
+-------+--------------------------------------+

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 openstack-nova-scheduler.service \
  openstack-nova-conductor.service openstack-nova-novncproxy.service

Note again that the nova-consoleauth service may not be necessary here.
