OpenStack计费服务

cloudkitty服务介绍
当前版本cloudkitty可以完成虚拟机实例（compute），云硬盘（volume），镜像（image），网络进出流量（network.bw.in,network.bw.out），浮动IP（network.floating）的计费。得益于Cloudkitty的巧妙而优秀的设计，软件插件化思想更是体现的淋漓尽致，使得添加新的计费源异常容易，版本升级十分方便。同样也能方便将cloudkitty用于cloudstack，VMWare等环境中。

Cloudkitty主要依赖于遥测相关的项目，包括ceilometer和gnocchi，甚至是将要使用panko；计费策略和hashmap计费模型是其核心；模块插件化是其设计灵魂；

使用命令编辑/etc/openstack/openrc.sh配置文件，添加Cloudkitty环境变量参数

##--------------------Cloudkitty Config----------------##
##Password for Mysql Cloudkitty user. exmaple:000000
CLOUDKITTY_DBPASS=000000

##Password for Keystore Cloudkitty user. exmaple:000000
CLOUDKITTY_PASS=000000

使用CRT等远程连接工具，连接至172.30.17.14控制节点，执行iaas-install- cloudkitty.sh安装脚本

[root@controller ~]# iaas-install-cloudkitty.sh

创建云主机服务instance_test，通过命令创建service服务

[root@controller ~]# openstack rating hashmap service create instance_test
+---------------+--------------------------------------+
| Name          | Service ID                           |
+---------------+--------------------------------------+
| instance_test | cf8029bf-dc35-4e40-b8fd-5af4a4d25a30 |
+---------------+--------------------------------------+

并对其创建名为flavor_name的fields

[root@controller ~]# openstack rating hashmap field create cf8029bf-dc35-4e40-b8fd-5af4a4d25a30 flavor_name
+-------------+--------------------------------------+--------------------------------------+
| Name        | Field ID                             | Service ID                           |

+-------------+--------------------------------------+--------------------------------------+

并设置规格为m1.small的云主机单价为1元

[root@controller ~]# openstack rating hashmap mapping create  --field-id b2f0d485-df20-4f2e-bd44-d3696971cb8f  -t flat --value  m1.small 1

  -ac46-1a8eb70d76e4                            -bd44-d3696971cb8f
+--------------------+--------+----------+----+--------------------+----------+--------+----------+

创建镜像收费服务image_size_test

[root@controller ~]# openstack rating hashmap service create image_size_test
+-----------------+--------------------------------------+
| Name            | Service ID                           |
+-----------------+--------------------------------------+
| image_size_test | 80a098cf-d793-47cf-b63e-df6cbd56e88d |
+-----------------+--------------------------------------+

并为该服务单价设置为0.8元

[root@controller ~]# openstack rating hashmap mapping create -s  80a098cf-d793-47cf-b63e-df6cbd56e88d   -t flat 0.8 
+--------------------+-------+------------+------+----------+--------------------+--------+----------+

+--------------------+-------+------------+------+----------+--------------------+--------+----------

创建名为dis_tests的服务

[root@controller ~]# openstack rating hashmap service create dis_tests

| dis_tests | b6190077-80ff-4e1f-9938-ddaff11c3506 |
+-----------+--------------------------------------+

为dis_tests服务设置单价为0.8元

[root@controller ~]# openstack rating hashmap mapping create -s  b6190077-80ff-4e1f-9938-ddaff11c3506  -t flat 0.8
