创建数据库nova_cell0并授权
CREATE DATABASE nova_cell0;
GRANT ALL PRIVILEGES ON nova_cell0.* TO ‘nova‘@‘localhost‘ IDENTIFIED BY ‘nova‘;
GRANT ALL PRIVILEGES ON nova_cell0.* TO ‘nova‘@‘%‘ IDENTIFIED BY ‘nova‘;

创建novay用户
source /admin-openstack.sh

[root@localhost ~]# openstack user create --domain default --password-prompt nova
User Password:
Repeat User Password:
+---------------------+----------------------------------+
| Field | Value |
+---------------------+----------------------------------+
| domain_id | default |
| enabled | True |
| id | 5bbf1e37ef5e472e9c4cd495262b5f72 |
| name | nova |
| options | {} |
| password_expires_at | None |
+---------------------+----------------------------------+

把nova用户加入service的项目并授予admin的角色
openstack role add --project service --user nova admin

创建nova服务（不能创建多个）
openstack service create --name nova \
--description "OpenStack Compute" compute

创建三个url
openstack endpoint create --region RegionOne \
compute public http://192.168.2.11:8774/v2.1

openstack endpoint create --region RegionOne \
compute internal http://192.168.2.11:8774/v2.1

openstack endpoint create --region RegionOne \
compute admin http://192.168.2.11:8774/v2.1

创建placement用户
[root@localhost ~]# openstack user create --domain default --password-prompt placement
User Password:
Repeat User Password:
+---------------------+----------------------------------+
| Field | Value |
+---------------------+----------------------------------+
| domain_id | default |
| enabled | True |
| id | 97b2e35868f24c20af240937c74071b7 |
| name | placement |
| options | {} |
| password_expires_at | None |
+---------------------+----------------------------------+

把placement用户加入service的项目并授予admin的角色
openstack role add --project service --user placement admin

openstack endpoint create --region RegionOne \
placement internal http://192.168.2.11:8778

openstack endpoint create --region RegionOne \
placement admin http://192.168.2.11:8778

[root@localhost ~]# openstack endpoint create --region RegionOne \
> placement admin http://192.168.2.11:8778

openstack endpoint list

安装服务
yum install openstack-nova-api openstack-nova-conductor \
openstack-nova-console openstack-nova-novncproxy \
openstack-nova-scheduler openstack-nova-placement-api

修改配置文件
vim /etc/nova/nova.conf

vim /etc/httpd/conf.d/00-nova-placement-api.conf
#添加
<Directory /usr/bin>
<IfVersion >= 2.4>
Require all granted
</IfVersion>
<IfVersion < 2.4>

</Directory>

重启httpd
systemctl restart httpd

同步api数据库
su -s /bin/sh -c "nova-manage api_db sync" nova

同步cell0数据库
u -s /bin/sh -c "nova-manage cell_v2 map_cell0" nova

创建cell1
su -s /bin/sh -c "nova-manage cell_v2 create_cell --name=cell1 --verbose" nova

同步nova数据库
su -s /bin/sh -c "nova-manage db sync" nova

验证nova cell0和cell1是否正确注册：
su -s /bin/sh -c "nova-manage cell_v2 list_cells" nova

[root@localhost ~]# su -s /bin/sh -c "nova-manage cell_v2 list_cells" nova
+-------+--------------------------------------+--------------------------------------+---------------------------------------------------+
| Name | UUID | Transport URL | Database Connection |
+-------+--------------------------------------+--------------------------------------+---------------------------------------------------+

+-------+--------------------------------------+--------------------------------------+---------------------------------------------------+

启动Compute服务并将其配置为在系统引导时启动：
systemctl enable openstack-nova-api.service \
openstack-nova-scheduler.service openstack-nova-conductor.service \
openstack-nova-novncproxy.service

systemctl start openstack-nova-api.service \
openstack-nova-scheduler.service openstack-nova-conductor.service \
openstack-nova-novncproxy.service
