Openstack Queens 环境搭建（五）Nova服务

Controller节点：1、创建 nova_api, nova,和 nova_cell0 的数据库，授予权限：$ mysql -u root -pMariaDB [(none)]>CREATE DATABASE nova_api;MariaDB [(none)]> CREATE DATABASE nova;MariaDB [(none)]> CREATE DATABASE nova_cell0;MariaDB [(none)]> GRANT ALL PRIVILEGES ON nova_api.* TO ’nova’@’localhost’ IDENTIFIED BY ‘123456’;MariaDB [(none)]> GRANT ALL PRIVILEGES ON nova_api.* TO ’nova’@’%’ IDENTIFIED BY
