- 创建服务凭证
# openstack user create --domain default --password-prompt nova
输入密码：NOVA_PASS
确认密码：NOVA_PASS
# openstack role add --project service --user nova admin
# openstack service create --name nova --description "OpenStack Compute" compute
- 创建服务API接入点
# 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
- 安装和配置
# yum install openstack-nova-api openstack-nova-conductor openstack-nova-novncproxy openstack-nova-scheduler -y
配置，修改配置文件/etc/nova/nova.conf，在对应分组【[组名]】下添加配置：

# su -s /bin/sh -c "nova-manage cell_v2 map_cell0" nova
# su -s /bin/sh -c "nova-manage cell_v2 create_cell --name=cell1 --verbose" nova
# su -s /bin/sh -c "nova-manage db sync" nova
验证：
# su -s /bin/sh -c "nova-manage cell_v2 list_cells" nova
设置开机启动并启动服务：
# systemctl enable openstack-nova-api.service openstack-nova-scheduler.service openstack-nova-conductor.service openstack-nova-novncproxy.service
# systemctl start openstack-nova-api.service openstack-nova-scheduler.service openstack-nova-conductor.service openstack-nova-novncproxy.service
- 验证
状态是否正常：
# openstack compute service list
验证接入点:
# curl controller:8774/v2.1
- 说明
- 详细说明参考官网：
https://docs.openstack.org/nova/train/install/controller-install-rdo.html - 安装mysql时做了安装初始化，将密码设置为无，如有设置密码，连接时请加账号密码。
- 安装spice console参考《2.6.安装Spice控制台》。
安装Neutron（组网服务）
需要2张网卡（网卡配置相关参考《OpenStack-train版安装之环境准备中WMware添加网卡》），采用vxlan方式组网。
- 数据库创建、创建用户并授权
# mysql
MariaDB [(none)]> CREATE DATABASE neutron;
MariaDB [(none)]> GRANT ALL PRIVILEGES ON neutron.* TO 'neutron'@'localhost' \
IDENTIFIED BY 'NEUTRON_DBPASS';
MariaDB [(none)]> GRANT ALL PRIVILEGES ON neutron.* TO 'neutron'@'%' \
IDENTIFIED BY 'NEUTRON_DBPASS';

# openstack user create --domain default --password-prompt neutron
输入密码：NEUTRON_PASS
确认密码：NEUTRON_PASS
# openstack role add --project service --user neutron admin
# openstack service create --name neutron --description "OpenStack Networking" network
- 创建服务API接入点
# openstack endpoint create --region RegionOne network public http://controller:9696
# openstack endpoint create --region RegionOne network internal http://controller:9696
# openstack endpoint create --region RegionOne network admin http://controller:9696
