【openstack】cloudkitty组件，入门级安装（快速）

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：

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

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 +---------------------+----------------------------------+ | Field               | Value                            | +---------------------+----------------------------------+ | domain_id           | d5db5c4ee4a14492b69408f63107d11f | | enabled             | True                             | | id                  | f1dea9309b834edba3aa4c1b8607dc16 | | name                | cloudkitty                       | | options             | {}                               | | password_expires_at | None                             | +---------------------+----------------------------------+ 

[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                            | +-----------+----------------------------------+ | domain_id | None                             | | id        | ee01d36a397b4b0ebcb579044c32a73c | | name      | rating                           | +-----------+----------------------------------+ 

创建rating服务及其端点：

[root@controller ~]# openstack service create --name cloudkitty --description "OpenStack rating" rating +-------------+----------------------------------+ | Field       | Value                            | +-------------+----------------------------------+ | description | OpenStack rating                 | | enabled     | True                             | | id          | 78f3d51cf74843cd8d325b790e0c2b1c | | name        | cloudkitty                       | | type        | rating                           | +-------------+----------------------------------+
