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
+———————+———————————-+

| 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 |
+————-+———————————-+
| description | OpenStack Compute |

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 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]

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

/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.
Getting computes from cell ‘cell1’: c795b2eb-4814-4fe7-b9ff-090a1b1b2be5
Checking host mapping for compute host ‘localhost.localdomain’: 58be78ad-5220-4869-ab31-33c9674ecfd1
Creating host mapping for compute host ‘localhost.localdomain’: 58be78ad-5220-4869-ab31-33c9674ecfd1
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
