openstack组件部署 3-阿里云开发者社区

安装 Placement(只需要在控制节点执行)

OpenStack Placement 组件是 OpenStack 中的一个核心组件，它提供了资源调度和分配的功能。具体来说， Placement 组件允许 OpenStack 云管理员将物理主机的资源(如 CPU、内存、存储等)划分为虚拟机实例可以使用的资源池。这样，当用户请求创建虚拟机实例时， Placement 组件可以根据用户的需求和物理主机的资源情况，选择最合适的物理主机来创建虚拟机实例。这样可以充分利用物理主机的资源，提高云计算资源的利用率，同时也可以为用户提供高效、可靠的云计算服务。

安装Compute

OpenStack Compute 组件，也称为 Nova，是 OpenStack 平台中的核心组件之一，用于管理和创建虚拟机实例。它提供了一组 API，使用户可以通过网络访问和控制虚拟机的创建、销毁、启动、停止和暂停等操作。 Nova 还提供了一些高级功能，如自动扩展、负载均衡和弹性计算等，可以为用户提供更加灵活和高效的虚拟化环境。除此之外， Nova 还支持多种虚拟化技术，如 KVM、Xen、VMware 和 Hyper-V 等，可以为用户提供广泛的虚拟化选择。
