Openstack Newton Install Guide - Nova

Install and configure controller node

第一步：配置数据库

$ mysql -u root -p
mysql> CREATE DATABASE nova_api;
mysql> CREATE DATABASE nova;
mysql> GRANT ALL PRIVILEGES ON nova_api.* TO 'nova'@'localhost' \
  IDENTIFIED BY 'NOVA_DBPASS';
mysql> GRANT ALL PRIVILEGES ON nova_api.* TO 'nova'@'%' \
  IDENTIFIED BY 'NOVA_DBPASS';
mysql> GRANT ALL PRIVILEGES ON nova.* TO 'nova'@'localhost' \
  IDENTIFIED BY 'NOVA_DBPASS';
mysql> GRANT ALL PRIVILEGES ON nova.* TO 'nova'@'%' \
  IDENTIFIED BY 'NOVA_DBPASS';

第二步：配置nova账号

$ . admin-openrc
$ openstack user create --domain default \
  --password-prompt nova

User Password:
Repeat User Password:
