openstack中phpsdkphp-opencloud怎么用

這篇文章主要介紹了openstack中php sdk php-opencloud怎么用，具有一定借鑒價(jià)值，感興趣的朋友可以參考下，希望大家閱讀完這篇文章之后大有收獲，下面讓小編帶著大家一起了解一下。

創(chuàng)新互聯(lián)-專(zhuān)業(yè)網(wǎng)站定制、快速模板網(wǎng)站建設(shè)、高性價(jià)比新興網(wǎng)站開(kāi)發(fā)、企業(yè)建站全套包干低至880元,成熟完善的模板庫(kù),直接使用。一站式新興網(wǎng)站制作公司更省心,省錢(qián),快速模板網(wǎng)站建設(shè)找我們，業(yè)務(wù)覆蓋新興地區(qū)。費(fèi)用合理售后完善，10年實(shí)體公司更值得信賴。

openstack提供的是rest風(fēng)格的api接口，其說(shuō)明文檔見(jiàn)：

http://developer.openstack.org/api-ref-guides/bk-api-ref.pdf，為便于理解和簡(jiǎn)化調(diào)用，這里使用開(kāi)源的php sdk——php-opencoud。

composer：提供自動(dòng)加載的功能

guzzle：處理http請(qǐng)求

psr：提供日志功能

rackspace/php-opencloud/lib/OpenCloud：php封裝庫(kù)

OpenCloud不僅支持openstack的api，還支持Rackspace的api。

openstack中php sdk php-opencloud怎么用

由圖中看到，可以從OpenStack客戶端中根據(jù)需要獲取不同的服務(wù)對(duì)象。計(jì)算服務(wù)用來(lái)管理云主機(jī)，通過(guò)主機(jī)類(lèi)型、鏡像、密鑰對(duì)和網(wǎng)絡(luò)等數(shù)據(jù)就可以創(chuàng)建一臺(tái)云主機(jī)，而且能夠?qū)υ浦鳈C(jī)做出暫停、恢復(fù)、停止、開(kāi)始和重啟等多種操作，還可以得到基于web vnc的控制臺(tái)鏈接。對(duì)象存儲(chǔ)服務(wù)是以容器的形式來(lái)存放數(shù)據(jù)對(duì)象，可以給對(duì)象名稱設(shè)置路徑前綴來(lái)對(duì)對(duì)象進(jìn)行分類(lèi)，組織成類(lèi)似windows文件夾的結(jié)構(gòu)。
