MariaDB [(none)] CREATE DATABASE neutron;
MariaDB [(none)]> GRANT ALL PRIVILEGES ON neutron.* TO 'neutron'@'localhost' IDENTIFIED BY '123456';
MariaDB [(none)]> GRANT ALL PRIVILEGES ON neutron.* TO 'neutron'@'%' IDENTIFIED BY '123456';
MariaDB [(none)]> exit;2、创建neutron用户：
$ . admin-openrc
$ openstack user create --domain default --password-prompt neutron
User Password: 123456
Repeat User Password: 123456
