OpenStack 是一个开源的云计算管理平台，由几个主要的组件组合起来完成具体工作。OpenStack 支持几乎所有类型的云环境，项目目标是提供实施简单、可大规模扩展、丰富、标准统一的云计算管理平台。OpenStack通过各种互补的服务提供了基础设施即服务（IaaS）的解决方案，每个服务提供API以进行集成。
环境
消息队列
OpenStack 使用消息队列来协调服务之间的操作和状态信息，消息队列服务通常运行在控制节点上，也可以单独部署于其他服务器或消息队列集群。 OpenStack 支持多种消息队列服务，包括 RabbitMQ 、Qpid 、ZeroMQ 。大多数支持 OpenStack 的发行版都有指定的消息队列产品，本文与官方文档一致使用 RabbitMQ 若使用其他消息队列产品请查询相关使用文档。
Message queue for SUSE

OpenStack 的服务身份验证机制需要 Memcached 缓存 Token （令牌），此服务通常部署在控制节点上。对于生产环境来说，建议部署防火墙、身份验证等策略对其进行保护。

验证服务 KeyStone
Keystone(OpenStack Identity Service)是 OpenStack 框架中负责管理身份验证、服务规则和服务令牌功能的模块。用户访问资源需要验证用户的身份与权限，服务执行操作也需要进行权限检测，这些都需要通过 Keystone 来处理。Keystone 类似一个服务总线， 或者说是整个 OpenStack 框架的注册表， 其他服务通过 keystone 来注册其服务的 Endpoint（服务访问的URL），任何服务之间相互的调用， 需要经过 Keystone 的身份验证， 来获得目标服务的 Endpoint 来找到目标服务。
数据库操作
连接数据库
mysql -u root -p建立验证服务数据库
MariaDB [(none)]> CREATE DATABASE keystone;建立用户并授权
MariaDB [(none)]> GRANT ALL PRIVILEGES ON keystone.* TO 'keystone'@'localhost' \
IDENTIFIED BY 'KEYSTONE_DBPASS';
MariaDB [(none)]> GRANT ALL PRIVILEGES ON keystone.* TO 'keystone'@'%' \
IDENTIFIED BY 'KEYSTONE_DBPASS';小贴士：注意替换 KEYSTONE_DBPASS 为合适的密码。安装与配置
sudo yum install openstack-keystone httpd mod_wsgi修改配置文件
sudo vim /etc/keystone/keystone.conf修改 [database] 标签下的数据库密码 KEYSTONE_DBPASS
[database]
# ...
connection = mysql+pymysql://keystone:KEYSTONE_DBPASS@controller/keystone注意：此处使用主机名进行通讯，必须进行 host 解析后才能使用。
修改 [token] 标签下的内容
[token]
# ...
provider = fernet写入数据库数据
sudo su -s /bin/sh -c "keystone-manage db_sync" keystone初始化 Fernet 密钥仓库
sudo keystone-manage fernet_setup --keystone-user keystone --keystone-group keystone
sudo keystone-manage credential_setup --keystone-user keystone --keystone-group keystone重新引导服务
小贴士：在 OpenStack Queens 版本后，keystone 必须需要多个端口运行 v2 API 通过移除 v2 API keystone 服务可以运行在一个端口中。
sudo keystone-manage bootstrap --bootstrap-password ADMIN_PASS \
--bootstrap-admin-url http://controller:5000/v3/ \
--bootstrap-internal-url http://controller:5000/v3/ \
--bootstrap-public-url http://controller:5000/v3/ \
--bootstrap-region-id RegionOne小贴士：替换 ADMIN_PASS 为合适的密码。
配置 Apache HTTP 服务
sudo vim /etc/httpd/conf/httpd.conf添加以下一行
ServerName controller创建软链接
sudo ln -s /usr/share/keystone/wsgi-keystone.conf /etc/httpd/conf.d/小贴士：可以为了提高安全级别而添加 SSL 证书。
启动 Apache HTTP 服务
sudo systemctl enable httpd.service
sudo systemctl start httpd.service配置管理员账户
$ 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小贴士：替换 ADMIN_PASS 为正确的密码。创建域、项目、用户和角色

+------------+-----------------------------------------------------------------+创建客户端环境脚本
为了提高操作效率，可以创建包含用户身份信息的脚本进行验证，也称 OpenRC 文件。
小贴士：此类脚本无固定存放地点，但为了防止其他用户滥用，推荐放置于 /root 目录下。
创建 admin-openrc 文件并添加以下内容
export OS_PROJECT_DOMAIN_NAME=Default
export OS_USER_DOMAIN_NAME=Default
export OS_PROJECT_NAME=admin
export OS_USERNAME=admin
export OS_PASSWORD=ADMIN_PASS
