cloudkitty服務介紹
當前版本cloudkitty可以完成虛擬機器例項（compute），雲硬碟（volume），映象（image），網路進出流量（network.bw.in,network.bw.out），浮動IP（network.floating）的計費。得益於Cloudkitty的巧妙而優秀的設計，軟體外掛化思想更是體現的淋漓盡致，使得新增新的計費源異常容易，版本升級十分方便。同樣也能方便將cloudkitty用於cloudstack，VMWare等環境中。
Cloudkitty主要依賴於遙測相關的專案，包括ceilometer和gnocchi，甚至是將要使用panko；計費策略和hashmap計費模型是其核心；模組外掛化是其設計靈魂；
使用命令編輯/etc/openstack/openrc.sh配置檔案，新增Cloudkitty環境變數引數
##--------------------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等遠端連線工具，連線至172.30.17.14控制節點，執行iaas-install- cloudkitty.sh安裝指令碼
[root@controller ~]# iaas-install-cloudkitty.sh
