【Placement】服务 是从【nova】服务中拆分出来的组件作用是收集各个【node】节点的可用资源把【node】节点的资源统计写入到【MySQL】【Placement】服务会被【nova scheduler】服务进行调用【Placement】服务的监听端口是【8778】
1、登录数据库授权
1.Use the database access client to connect to the database server as the root user登录数据库
[rootcontroller ~]# mysql -p
Enter password:
Welcome to the MariaDB monitor. Commands end with ; or \g.
Your MariaDB connection id is 31
Server version: 10.3.20-MariaDB MariaDB ServerCopyright (c) 2000, 2018, Oracle, MariaDB Corporation Ab and others.Type help; or \h for help. Type \c to clear the current input statement.MariaDB [(none)] 2.Create the placement database数据库里创建placement
MariaDB [(none)] CREATE DATABASE placement;
3.Grant proper access to the placement database:
MariaDB [(none)] GRANT ALL PRIVILEGES ON placement.* TO placement% \IDENTIFIED BY 123;
4.退出数据库
MariaDB [(none)] quit
5.Create the glance user(创建glance用户密码为glance)
[rootcontroller opt]# openstack user create --domain default --password placement placement

| options | {} |
| password_expires_at | None |
-------------------------------------------------------6.Add the Placement user to the service project with the admin role:
[rootcontroller opt]# openstack role add --project service --user placement admin7.Create the Placement API entry in the service catalog:
[rootcontroller opt]# openstack service create --name placement \--description Placement API placement
-----------------------------------------------
| Field | Value |
-----------------------------------------------
| description | Placement API |
| enabled | True |
| id | 323767a9dc614360b805b17bad697337 |
| name | placement |
| type | placement |
-----------------------------------------------8.Create the Placement API service endpoints:
[rootcontroller opt]# openstack endpoint create --region RegionOne \placement public http://controller:8778
------------------------------------------------

------------------------------------------------2、安装palcement-api
1.安装palcement-api包
[rootcontroller opt]# yum install openstack-placement-api -y2.备份配置文件并且修改
[rootcontroller opt]# cp /etc/placement/placement.conf{,.bak}
[rootcontroller opt]# grep -Ev ^$|# /etc/placement/placement.conf.bak /etc/placement/placement.conf
[rootcontroller opt]# vi /etc/placement/placement.conf[DEFAULT]

----------------------------------安装部署Placement完成 Placement组件应该在Nova之前安装Placement服务跟踪资源比如计算节点存储资源池网络资源池等的使用情况提供自定义资源的能力为分配资源提供服务。Placement 肩负着这样的历史使命最早在 Newton 版本被引入到 openstack/nova repo以 API 的形式进行孵化所以也经常被称呼为 Placement API。它参与到 nova-scheduler 选择目标主机的调度流程中负责跟踪记录 Resource Provider 的 Inventory 和 Usage并使用不同的 Resource Classes 来划分资源类型使用不同的 Resource Traits 来标记资源特征。对于使用共享存储解决方案的用户希望 Nova 和 Horizon 能够正确报告共享存储磁盘资源的总量和使用量信息。对于 Neutron 会使用外部的第三方路由网络功能希望 Nova 能够掌握和使用特定的网络端口与特定的子网池相关联确保虚拟机能够在该子网池上启动。作为高级的 Cinder 希望当 nova boot 命令中指定了 cinder volume-id 后 Nova 能够知道哪一些计算节点与 Request Volume 所在的 Cinder 存储池相关联所以当资源类型和提供者变得多样时自然就需求一种高度抽象且简单统一的管理方法让用户和代码能够便捷的使用、管理、监控整个 OpenStack 的系统资源这就是 Placement布局
概括一个资源提供者可以是一个计算节点共享存储池或一个IP分配池。placement服务跟踪每个供应商的库存和使用情况。或者在一个计算节点创建一个实例的可消费资源如计算节点的资源提供者的CPU和内存磁盘从外部共享存储池资源提供商和IP地址从外部IP资源提供者。 OpenStack简介 | 常见的基础组件
