nova服务安装配置（controller）
###1.创建数据库
mysqlCREATE DATABASE nova_api;
CREATE DATABASE nova;
CREATE DATABASE nova_cell0;GRANT ALL PRIVILEGES ON nova_api.* TO 'nova'@'localhost' IDENTIFIED BY 'NOVA_DBPASS';
GRANT ALL PRIVILEGES ON nova_api.* TO 'nova'@'%' IDENTIFIED BY 'NOVA_DBPASS';
GRANT ALL PRIVILEGES ON nova.* TO 'nova'@'localhost' IDENTIFIED BY 'NOVA_DBPASS'；
GRANT ALL PRIVILEGES ON nova.* TO 'nova'@'%' IDENTIFIED BY 'NOVA_DBPASS';
GRANT ALL PRIVILEGES ON nova_cell0.* TO 'nova'@'localhost' IDENTIFIED BY 'NOVA_DBPASS';
GRANT ALL PRIVILEGES ON nova_cell0.* TO 'nova'@'%' IDENTIFIED BY 'NOVA_DBPASS';flush privileges;
exit###2.创建compute server
openstack user create --domain default --password-prompt novaUser Password: （nova）
Repeat User Password: （nova）+---------------------+----------------------------------+

| name | nova |
| options | {} |
| password_expires_at | None |
+---------------------+----------------------------------+###3. 增加权限
openstack role add --project service --user nova admin###4.创建nova service
openstack service create --name nova --description "OpenStack Compute" compute+-------------+----------------------------------+
