GRANT ALL PRIVILEGES ON nova.* TO 'nova'@'%' \
IDENTIFIED BY 'NOVA_DBPASS';
d.退出
exit
2.加载环境变量
source admin-openrc.sh
3.创建认证服务，完成下面内容

| name | nova |
| type | compute |
+-------------+----------------------------------+
4.创建novaAPI endpoint
openstack endpoint create \
--publicurl http://controller:8774/v2/%\(tenant_id\)s \
--internalurl http://controller:8774/v2/%\(tenant_id\)s \
--adminurl http://controller:8774/v2/%\(tenant_id\)s \
--region RegionOne \
compute
+--------------+-----------------------------------------+
| Field | Value |
+--------------+-----------------------------------------+
| adminurl | http://controller:8774/v2/%(tenant_id)s |
| id | 4e885d4ad43f4c4fbf2287734bc58d6b |
| internalurl| http://controller:8774/v2/%(tenant_id)s |
| publicurl | http://controller:8774/v2/%(tenant_id)s |
| region | RegionOne |
| service_id | 060d59eac51b4594815603d75a00aba2 |

...
rabbit_host = controller
rabbit_userid = openstack
rabbit_password = RABBIT_PASS
替换RABBIT_PASS 为自己设置密码，
c. 在 和 部分，配置keystone服务
...
auth_strategy = keystone
...
auth_uri = http://controller:5000
auth_url = http://controller:35357
auth_plugin = password
project_domain_id = default
user_domain_id = default
project_name = service
username = nova
password = NOVA_PASS
d.在部分，配置my_ip （控制节点管理网络ip地址）
...
my_ip = 10.0.0.11
e.在 部分，控制节点管理网络配置VNC proxy
...

vncserver_proxyclient_address = 10.0.0.11
f.在 部分，配置glancehost
...
host = controller
g.在 部分，配置 lock 路径
...
lock_path = /var/lib/nova/tmp
h.启用详细信息日志记录
...
verbose = True
同步数据库
su -s /bin/sh -c "nova-manage db sync" nova
验证安装
systemctl enable openstack-nova-api.service openstack-nova-cert.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-cert.service \
