Controller节点：
1、创建 nova_api, nova,和 nova_cell0 的数据库，授予权限：

$ mysql -u root -p

MariaDB [(none)]>CREATE DATABASE nova_api;
MariaDB [(none)]> CREATE DATABASE nova;
MariaDB [(none)]> CREATE DATABASE nova_cell0;

MariaDB [(none)]> GRANT ALL PRIVILEGES ON nova_api.* TO 'nova'@'localhost' IDENTIFIED BY '123456';
MariaDB [(none)]> GRANT ALL PRIVILEGES ON nova_api.* TO 'nova'@'%' IDENTIFIED BY '123456';
MariaDB [(none)]> GRANT ALL PRIVILEGES ON nova.* TO 'nova'@'localhost' IDENTIFIED BY '123456';
MariaDB [(none)]> GRANT ALL PRIVILEGES ON nova.* TO 'nova'@'%' IDENTIFIED BY '123456';
MariaDB [(none)]> GRANT ALL PRIVILEGES ON nova_cell0.* TO 'nova'@'localhost' IDENTIFIED BY '123456';
MariaDB [(none)]> GRANT ALL PRIVILEGES ON nova_cell0.* TO 'nova'@'%' IDENTIFIED BY '123456';

MariaDB [(none)]> exit;

2、创建nova用户：

$ . admin-openrc

$ openstack user create --domain default --password-prompt nova
User Password: 123456
Repeat User Password: 123456
+---------------------+----------------------------------+
| Field               | Value                            |
+---------------------+----------------------------------+
| domain_id           | default                          |
| enabled             | True                             |
| id                  | 81f1d5dfad5a42bb806d197ceb9881ce |
| name                | nova                             |
| options             | {}                               |
| password_expires_at | None                             |
+---------------------+----------------------------------+

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

3、创建nova服务实体：

$ openstack service create --name nova --description "OpenStack Compute" compute
+-------------+----------------------------------+
| Field       | Value                            |

6、安装和配置：

# yum install openstack-nova-api openstack-nova-conductor openstack-nova-console openstack-nova-novncproxy openstack-nova-scheduler openstack-nova-placement-api

# vi /etc/nova/nova.conf

      Require all granted
   </IfVersion>
   <IfVersion < 2.4>

      Allow from all
   </IfVersion>
</Directory>

7、完成安装：

# systemctl restart httpd

# su -s /bin/sh -c "nova-manage api_db sync" nova
# su -s /bin/sh -c "nova-manage cell_v2 map_cell0" nova
# su -s /bin/sh -c "nova-manage cell_v2 create_cell --name=cell1 --verbose" nova
# su -s /bin/sh -c "nova-manage db sync" nova

# nova-manage cell_v2 list_cells

# 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

Compute节点：
1、安装和配置：

# yum install openstack-nova-compute

# vi /etc/nova/nova.conf
[DEFAULT]
my_ip = 192.100.10.161
enabled_apis = osapi_compute,metadata
use_neutron = True
firewall_driver = nova.virt.firewall.NoopFirewallDriver
transport_url = rabbit://openstack:123456@controller
[api]
auth_strategy = keystone
[vnc]
enabled = True
server_listen = 0.0.0.0
server_proxyclient_address = $my_ip
novncproxy_base_url = http://controller:6080/vnc_auto.html
[glance]
api_servers = http://controller:9292
[oslo_concurrency]
lock_path = /var/lib/nova/tmp
[placement]
os_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 = 123456
[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 = 123456

2、完成安装：

# systemctl enable libvirtd.service openstack-nova-compute.service
# systemctl start libvirtd.service openstack-nova-compute.service

Controller节点：
1、将计算节点添加到cell数据库：

$ . admin-openrc

$ openstack compute service list --service nova-compute
+----+--------------+-----------------------+------+---------+-------+----------------------------+
| ID | Binary       | Host                  | Zone | Status  | State | Updated At                 |
+----+--------------+-----------------------+------+---------+-------+----------------------------+
|  9 | nova-compute | localhost.localdomain | nova | enabled | up    | 2018-09-13T02:59:06.000000 |
+----+--------------+-----------------------+------+---------+-------+----------------------------+

2、发现计算主机：

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

/usr/lib/python2.7/site-packages/oslo_db/sqlalchemy/enginefacade.py:332: NotSupportedWarning: Configuration option(s) ['use_tpool'] not supported
  exception.NotSupportedWarning
Found 2 cell mappings.
Skipping cell0 since it does not contain hosts.

Found 1 unmapped computes in cell: c795b2eb-4814-4fe7-b9ff-090a1b1b2be5

注意：添加新计算节点时，必须在控制器节点上运行nova-manage cell_v2 discover_hosts以注册这些新计算节点。
或者，您可以在 /etc/nova/nova.conf 中设置适当的间隔：
[scheduler]
discover_hosts_in_cells_interval = 300

3、验证：

$ . admin-openrc

$ openstack compute service list
+----+------------------+-----------------------+----------+---------+-------+----------------------------+
