玩转企业云计算平台系列(十五):Openstack 计费服务 Cloudkitty

Cloudkitty 服务介绍

OpenStack 计费服务(CloudKitty)是一个用于云计算资源计费和成本管理的工具。

假设你去一家自助餐厅吃饭,餐厅提供了各种不同的食物和饮料选择。你可以根据自己的需求选择不同的食物和饮料,然后在结账时按照你所选择的食物和饮料的种类和数量付费。

OpenStack 就是这家自助餐厅,它提供了各种云计算资源,比如虚拟机、存储和网络等。你可以根据自己的需求选择使用这些资源。

而计费服务(CloudKitty)就像是这家自助餐厅的收银台。它会记录你使用的资源种类和数量,并根据预定的计费规则计算出相应的费用。这些计费规则可以根据不同的资源类型和使用方式进行定制,以确保计费的准确性。当你使用完资源后,计费服务会生成一份详细的费用报告,告诉你每个资源的使用情况和相应的费用。这样,你就可以清楚地知道自己使用了哪些资源以及需要支付多少费用。

CloudKitty 架构

CloudKitty 可以分为四大部分:

  • Data retrieval (API) 数据检索
  • Data collection (cloudkitty-processor) 数据收集
  • Data rating 数据评级
  • Data storage 数据存储

这些部分由两个进程处理:数据检索部分由进程cloudkitty-api处理,其他部分由 cloudkitty-processor 处理。

安装准备

在安装计费服务之前,你必须创建数据库、服务凭证和 API 端点

创建数据库

①连接数据库

代码语言:javascript
复制
[root@controller ~]# mysql -uroot -p000000

②创建cloudkitty数据库

代码语言:javascript
复制
MariaDB [(none)]> CREATE DATABASE cloudkitty;

③授权

代码语言:javascript
复制
MariaDB [(none)]> GRANT ALL PRIVILEGES ON cloudkitty.* TO 'cloudkitty'@'localhost' IDENTIFIED BY '000000';
MariaDB [(none)]> GRANT ALL PRIVILEGES ON cloudkitty.* TO 'cloudkitty'@'%' IDENTIFIED BY '000000';
加载admin user 环境变量
代码语言:javascript
复制
[root@controller ~]# source admin-openrc.sh 
创建服务凭证

①创建cloudkitty用户

代码语言:javascript
复制
[root@controller ~]# openstack user create  --domain default  --password 000000 cloudkitty
