2、 安装nova准备
2.1 创建数据库
mysql
CREATE DATABASE nova_api;
CREATE DATABASE nova;
CREATE DATABASE nova_cell0;
show databases;
exit
[root@openstack-controller ~]# mysql

2.3 加载服务凭据
source openrc
[root@openstack-controller ~]# cat openrc
export OS_USERNAME=admin
export OS_PASSWORD=ADMIN_PASS
export OS_PROJECT_NAME=admin
export OS_USER_DOMAIN_NAME=Default
export OS_PROJECT_DOMAIN_NAME=Default
export OS_AUTH_URL=http://controller:5000/v3
export OS_IDENTITY_API_VERSION=3
[root@openstack-controller ~]# source openrc
2.4 创建openstack的nova用户
openstack user create --domain default --password nova nova
[root@openstack-controller ~]# openstack user create --domain default --password nova nova
+---------------------+----------------------------------+
| Field | Value |
+---------------------+----------------------------------+
