Before you install and configure the Compute service, you must create databases, service credentials, and API endpoints.
在安裝和被指Compute service之前，你必須先創建Compute service的數據庫、服務證書和API Endpoints。
Use the database access client to connect to the database server as the root user:
使用root用戶登錄到MySQL
mysql -u root -pfanguijuCreate the nova_api and nova databases:
創建nova_api和nova兩個數據庫
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:
創建nova和nova_api數據庫的用戶nova，并授與nova用戶對nova和nova_api數據庫的完全控制權限。
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環境變量腳本
. admin-openrcCreate the nova user:
創建nova用戶
[root@controller ~]# openstack user create --domain default --password-prompt nova
User Password:
Repeat User Password:

將Role admin添加到Project service中的User nova中
openstack role add --project service --user nova adminCreate the nova service entity:
創建nova服務實體

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：默許的，Compute會使用1個internal firewall driver。由于Networking service包括了1個firewall driver，所以你必須通過nova.virt.firewall.NoopFirewallDriver firewall driver來關閉這個Compute firewall driver
