6.1 创建nova数据库
mysql -u root -pabc-123
---
create database nova_api;
crate database nova;
create database nova_cell0;
create database placement;
grant all privileges on nova_api.* to 'nova'@'localhost' identified by 'nova';
grant all privileges on nova_api.* to 'nova'@'%' identified by 'nova';
grant all privileges on nova.* to 'nova'@'localhost' identified by 'nova';
grant all privileges on nova.* to 'nova'@'%' identified by 'nova';
grant all privileges on nova_cell0.* to 'nova'@'localhost' identified by 'nova';
grant all privileges on nova_cell0.* to 'nova'@'%' identified by 'nova';
grant all privileges on placement.* to 'nova'@'localhost' identified by 'nova';
grant all privileges on placement.* to 'nova'@'%' identified by 'nova';
flush privileges;
exit
6.2 Keystone注册nova
6.2.1 Keystone创建nova用户
openstack user create --domain default --password=nova nova
6.2.2 Keystone中将nova用户添加为admin权限并且添加进test项目
openstack role add --project test --user nova admin
6.2.3 创建nova计算服务
openstack service create --name nova --description "OpenStack Compute" compute
openstack service list
6.2.4 创建nova的API服务（endpoint）
openstack endpoint create --region RegionOne compute public http://controller:8774/v2.1
openstack endpoint create --region RegionOne compute internal http://controller:8774/v2.1
openstack endpoint create --region RegionOne compute admin http://controller:8774/v2.1
openstack endpoint list
6.2.5 增加了placement项目
openstack user create --domain default --password=placement placement
openstack role add --project test --user placement admin
openstack service create --name placement --description "Placement API" placement
6.2.6 增加placement的API服务（endpoint）
主要追踪每个提供者的库存和使用量情况，比如追踪计算节点的资源，存储池的使用情况以及IP的分配情况等等。
openstack endpoint create --region RegionOne placement public http://controller:8778
openstack endpoint create --region RegionOne placement internal http://controller:8778
openstack endpoint create --region RegionOne placement admin http://controller:8778
openstack endpoint list
