前言

什么是CloudKitty？
CloudKitty是OpenStack等的评级即服务项目。该项目旨在成为云的退款和评级的通用解决方案。从历史上看，它只能在OpenStack上下文中运行它，但现在可以在独立模式下运行CloudKitty。

CloudKitty允许进行基于指标的评级：它轮询终端节点以检索有关特定指标的度量值和元数据，将评级规则应用于收集的数据，并将评级数据推送到其存储后端。

CloudKitty是高度模块化的，这使得添加新功能变得容易。

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：和 。数据检索部分由进程处理，其他部分由 处理。cloudkitty-apicloudkitty-processorcloudkitty-apicloudkitty-processor

以下是 CloudKitty 架构的概述：
在这里插入图片描述

安装 
yum install openstack-cloudkitty-api openstack-cloudkitty-processor openstack-cloudkitty-ui
配置

编辑/etc/cloudkitty/cloudkitty.conf以配置 CloudKitty

[DEFAULT]
verbose = True
log_dir = /var/log/cloudkitty

[oslo_messaging_rabbit]
rabbit_userid = openstack
rabbit_password = RABBIT_PASSWORD
rabbit_hosts = RABBIT_HOST

[auth]
username = cloudkitty
password = CK_PASSWORD
tenant = service
region = RegionOne
url = http://localhost:5000/v2.0

[keystone_authtoken]
username = cloudkitty
password = CK_PASSWORD
project_name = service
region = RegionOne
auth_url = http://localhost:5000/v2.0
auth_plugin = password

[database]
connection = mysql://cloudkitty:CK_DBPASS@localhost/cloudkitty

[keystone_fetcher]
username = admin
password = ADMIN_PASSWORD
tenant = admin
region = RegionOne
url = http://localhost:5000/v2.0

[ceilometer_collector]
username = cloudkitty
password = CK_PASSWORD
tenant = service
region = RegionOne
url = http://localhost:5000

设置数据库和存储后端

[root@controller ~]# mysql -uroot -p000000

CloudKitty 使用 Keystone 进行身份验证，并提供rating服务。

[root@controller ~]# openstack user create --domain demo --password 000000 cloudkitty

[root@controller ~]# openstack role add --project service --user cloudkitty admin

对于应由 CloudKitty处理的每个租户，将rating角色赋予 cloudkitty ：

[root@controller ~]# openstack role create rating
+-----------+----------------------------------+
| Field     | Value                            |

| name      | rating                           |
+-----------+----------------------------------+

创建rating服务及其端点：

[root@controller ~]# openstack service create --name cloudkitty --description "OpenStack rating" rating
