Before you install and configure the Compute service, you must create databases, service credentials, and API endpoints.
在安装和被指Compute service之前，你必须先创建Compute service的数据库、服务证书和API Endpoints。
Use the database access client to connect to the database server as the root user:
使用root用户登录到MySQL
mysql -u root -pfanguijuCreate the nova_api and nova databases:
创建nova_api和nova两个数据库
MariaDB [(none)]> CREATE DATABASE nova_api;
Query OK, 1 row affected (0.00 sec)
MariaDB [(none)]> CREATE DATABASE nova;
Query OK, 1 row affected (0.00 sec)Grant proper access to the databases:
创建nova和nova_api数据库的用户nova，并授与nova用户对nova和nova_api数据库的完全控制权限。
GRANT ALL PRIVILEGES ON nova_api.* TO 'nova'@'localhost' IDENTIFIED BY 'fanguiju';
GRANT ALL PRIVILEGES ON nova_api.* TO 'nova'@'%' IDENTIFIED BY 'fanguiju';
GRANT ALL PRIVILEGES ON nova.* TO 'nova'@'localhost' IDENTIFIED BY 'fanguiju';
GRANT ALL PRIVILEGES ON nova.* TO 'nova'@'%' IDENTIFIED BY 'fanguiju';Example:
MariaDB [(none)]> GRANT ALL PRIVILEGES ON nova_api.* TO 'nova'@'localhost' IDENTIFIED BY 'fanguiju';
Query OK, 0 rows affected (0.00 sec)
MariaDB [(none)]> GRANT ALL PRIVILEGES ON nova_api.* TO 'nova'@'%' IDENTIFIED BY 'fanguiju';
Query OK, 0 rows affected (0.00 sec)
MariaDB [(none)]> GRANT ALL PRIVILEGES ON nova.* TO 'nova'@'localhost' IDENTIFIED BY 'fanguiju';
Query OK, 0 rows affected (0.00 sec)
MariaDB [(none)]> GRANT ALL PRIVILEGES ON nova.* TO 'nova'@'%' IDENTIFIED BY 'fanguiju';
Query OK, 0 rows affected (0.00 sec)Exit the database access client
Source the admin credentials to gain access to admin-only CLI commands:
履行admin环境变量脚本
. admin-openrcCreate the nova user:
创建nova用户
[root@controller ~]# openstack user create --domain default --password-prompt nova
User Password:
Repeat User Password:

+-----------+----------------------------------+Add the admin role to the nova user:
将Role admin添加到Project service中的User nova中
openstack role add --project service --user nova adminCreate the nova service entity:
创建nova服务实体

firewall_driver = nova.virt.firewall.NoopFirewallDriverNote: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.
注意：默许的，Compute会使用1个internal firewall driver。由于Networking service包括了1个firewall driver，所以你必须通过nova.virt.firewall.NoopFirewallDriver firewall driver来关闭这个Compute firewall driver
