- 在director节点上，验证底层云的网络和服务。
- 在director节点上，查找overcloud节点的IP地址。列出网络并显示ctlplane子网的详细信息。打开undercloud.conf文件并查看DHCP配置。
- 在所有四个overcloud节点上，使用docker命令来显示OpenStack服务
- 使用docker命令停止nova_api容器。检查容器的状态，然后重新启动它。确保容器返回健康状态。5. 在controller0和compute0节点上，查看etho、vlan和br-ex接口。列出OVS网桥。列出br-ex和br-trunk上的OVS接口。
- 在workstation，加载源~/operator1-production-rc认证文件。使用下表中的属性在production项目中创建一个实例。确保服务器的状态为ACTIVE。在provider-datacentre网络上创建一个浮动IP地址，并将其附加到实例。

[student@workstation ~(operator1-production)]$ lab architecture-lab cleanup💡总结
- 当今的企业云是使用多个相互连接的云结构构建的。undercloud是用于构建和管理生产云的供应和管理云。Red Hat OpenStack平台Director是Red Hat OpenStack平台的底层。
- 企业生产云称为overcloud。Underclouds和overclouds使用相同的技术，但是管理不同的工作负载。底层管理云基础设施，上层管理生产和租户工作负载。
- 物理云和虚拟云中使用了常见的开放技术。智能平台管理接口(IPMI)是用于控制节点的电源管理技术。虚拟网络计算(VNC)是一种远程访问技术，用于访问已部署的实例控制台。
- 自省过程具有发现要部署节点的技术特征。通过使用这些特征，overcloud部署可以自动将部署角色分配给特定节点。
- 编排流程为每个节点的硬件和软件定义特定的配置。所提供的默认模板涵盖了大多数常见用例和设计。
- 红帽OpenStack平台的最新版本使用容器来运行服务。systemd命令已被弃用，并已被docker命令替换。日志文件现在位于/var/log/containers/service中，配置文件现在位于/var/lib/configdata/puppet-generated/service/etc/service中。只有在容器配置文件中所做的更改在重新启动服务时才会持久。
RHCA认证需要经历5门的学习与考试，还是需要花不少时间去学习与备考的，好好加油，可以噶🤪。
以上就是【金鱼哥】对 第一章 红帽OpenStack平台架构--章节实验 的简述和讲解。希望能对看到此文章的小伙伴有所帮助。
