openstack提供的是rest风格的api接口，其说明文档见：

http://developer.openstack.org/api-ref-guides/bk-api-ref.pdf，为便于理解和简化调用，这里使用开源的php sdk——php-opencoud。

1 目录结构

vendor

---------composer
---------guzzle
---------psr
---------rackspace
           --------------php-opencloud
               ---------------------docs
               ---------------------lib
                                       ---OpenCloud
               ---------------------samples
               ---------------------tests

composer：提供自动加载的功能

guzzle：处理http请求

psr：提供日志功能

rackspace/php-opencloud/lib/OpenCloud：php封装库

OpenCloud不仅支持openstack的api，还支持Rackspace的api。

openstack中php sdk php-opencloud怎么用

由图中看到，可以从OpenStack客户端中根据需要获取不同的服务对象。计算服务用来管理云主机，通过主机类型、镜像、密钥对和网络等数据就可以创建一台云主机，而且能够对云主机做出暂停、恢复、停止、开始和重启等多种操作，还可以得到基于web vnc的控制台链接。对象存储服务是以容器的形式来存放数据对象，可以给对象名称设置路径前缀来对对象进行分类，组织成类似windows文件夹的结构。

3 示例代码

3.1 计算服务

'admin', 'password' => 'ADMIN_PASS', 'tenantName' => 'admin' )); $computeService = $client->computeService('nova','regionOne'); //1.枚举镜像 $p_w_picpaths = $computeService->p_w_picpathList(); printf("Images-------------------------------------------------------------------------\n"); foreach($p_w_picpaths as $p_w_picpath) { printf("ID:%s,Name:%s\n",$p_w_picpath->id,$p_w_picpath->name); } //2.枚举主机类型 $flavors = $computeService->flavorList(); printf("Flavors-------------------------------------------------------------------------\n"); foreach($flavors as $flavor) { printf("ID:%-36s,Name:%-36s,Vcpus:%d,Ram:%d\n",$flavor->id,$flavor->name,$flavor->vcpus,$flavor->ram); } //3.枚举密钥对(for windows:加密密码传输 for linux:ssh登录) $keypairs = $computeService->listKeypairs(); printf("Keypairs------------------------------------------------------------------------\n"); foreach($keypairs as $keypair) { printf("Name:%s\n",$keypair->getName()); } //4.创建云主机 $server = $computeService->server(); printf("Create Server-------------------------------------------------------------------\n"); $serverName = 'test123'; $p_w_picpathId = 'c36b0707-38ec-45e5-9d62-7e8798f1724f'; $flavorId = '53b1355a-c7c6-41a6-884f-7b1604002897'; $keypairName = 'testKey'; try { $response = $server->create(array( 'name' => $serverName, 'p_w_picpathId' => $p_w_picpathId, 'flavorId' => $flavorId, 'keypair' => $keypairName, 'metadata' => array( 'admin_pass' => '123456',//设置密码 'appid' => '123456789' //设置自定义元数据 ))); }catch(BadResponseException $e) { echo $e->getResponse(); } printf("ID:%s,Name:%s,Status:%s\n",$server->id,$server->name,$server->status); function GetServerState($server) { printf("Status:%s\n",$server->status); } //wait for $server->waitFor(ServerState::ACTIVE,null,GetServerState,1); if (is_object($server->addresses)) { foreach ($server->addresses as $netkey => $netvalue) { printf("\tNetwork name:%s\n",$netkey); if (is_array($netvalue)) { foreach ($netvalue as $infokey => $infovalue) { printf("\t\tIndex:%s\n",$infokey); printf("\t\t\tMac: %s\n",$infovalue->{'OS-EXT-IPS-MAC:mac_addr'}); printf("\t\t\tVersion:%s\n",$infovalue->version); printf("\t\t\tAddr: %s\n",$infovalue->addr); printf("\t\t\tType: %s\n",$infovalue->{'OS-EXT-IPS:type'}); } } } } //5.获取vnc访问地址 printf("VNC-----------------------------------------------------------------------------\n"); $console = $server->console(); printf("Type:%s,URL:%s\n",$console->type,$console->url); //6.停止云主机 printf("Stop Server---------------------------------------------------------------------\n"); $server->stop(); $server->waitFor('SHUTOFF',null,GetServerState,1); //7.启动云主机 printf("Start Server--------------------------------------------------------------------\n"); $server->start(); $server->waitFor(ServerState::ACTIVE,null,GetServerState,1); //8.重启云主机 printf("ReBoot Server-------------------------------------------------------------------\n"); //$server->reboot(ServerState::REBOOT_STATE_SOFT);//REBOOT_STATE_SOFT:软重启 REBOOT_STATE_HARD:硬重启 //$server->waitFor(ServerState::ACTIVE,null,GetServerState,1); //9.删除云主机 printf("Delete Server-------------------------------------------------------------------\n"); $server->delete(); //10.获取镜像信息 printf("Image Info----------------------------------------------------------------------\n"); $p_w_picpath = $computeService->p_w_picpath($server->p_w_picpath->id); printf("ID:%s,Name:%s\n",$p_w_picpath->id,$p_w_picpath->name); //11.获取主机类型信息 printf("Flavor Info---------------------------------------------------------------------\n"); $flavor = $computeService->flavor($server->flavor->id); printf("ID:%s,Name:%s,Vcpus:%d,Ram:%d\n",$flavor->id,$flavor->name,$flavor->vcpus,$flavor->ram);

3.2 对象存储服务

'admin', 'password' => 'ADMIN_PASS', 'tenantName' => 'admin' )); //获取对象存储服务 $objectStoreService = $client->objectStoreService('swift', 'regionOne'); //1.创建容器(每个云盘使用者都有一个容器跟其对应) $containerName = 'testContainer'; printf("Create Container %s------------------------------------------------------\n",$containerName); //检查名字合法性 $objectStoreService->checkContainerName($containerName); $container = $objectStoreService->createContainer($containerName); if($container == false) { $container = $objectStoreService->getContainer($containerName); } else { //设置配额 $container->setBytesQuota(5 * Size::GB); // 5GB } //2.枚举容器 $containers = $objectStoreService->listContainers(); printf("Containers--------------------------------------------------------------------------\n"); foreach ($containers as $container) { $container = $objectStoreService->getContainer($container->name); printf("Name:%-60s,BytesUsed:%15.6fM,ObjectCount:%d",$container->name,$container->getBytesUsed() / 1024 / 1024,$container->getObjectCount()); $bytesQuota = $container->getBytesQuota(); if($bytesQuota) printf(",BytesQuota:%.6fM",$bytesQuota / 1024 / 1024); printf("\n"); } //3.容器添加对象 $container = $objectStoreService->getContainer($containerName); //添加文件 $customHeaders = array('Content-Type' => 'text/plain'); $fileData = fopen('D:/upload_small_object.txt', 'r'); $object = $container->uploadObject('upload_small_object.txt', $fileData,$customHeaders); //添加目录(注意后面的斜杠) $dirName = 'dir1/'; $object = $container->uploadObject($dirName,''); //目录添加文件(文件放到目录中，必须在文件名前加上目录，形成类似a/b/c/d/1.txt结构(目录a/,目录a/b/,目录a/b/c/,目录a/b/c/d/)) $fileData = fopen('D:/upload_small_object.txt', 'r'); $object = $container->uploadObject($dirName . 'upload_small_object.txt', $fileData,$customHeaders); //目录下再添加目录 $dirName = $dirName . 'dir1-1/'; $object = $container->uploadObject($dirName,''); //二级目录下再添加文件 $fileData = fopen('D:/upload_small_object.txt', 'r'); $object = $container->uploadObject($dirName . 'upload_small_object.txt', $fileData,$customHeaders); //4.枚举对象 printf("%s Objects-----------------------------------------------------------\n",$containerName); //是目录的最后一个字符是斜杠 $objects = $container->objectList(); foreach ($objects as $object) { printf("Name:%-60s,Size:%15.6fM,LastModified:%s\n",$object->getName(),$object->getContentLength(),$object->getLastModified()); } //5.枚举目录下的对象(设定前缀) printf("%s Objects---------------------------------------------------------------\n",$dirName); $objects = $container->objectList(array('prefix' => $dirName)); foreach ($objects as $object) { printf("Name:%-60s,Size:%15.6fM,LastModified:%s\n",$object->getName(),$object->getContentLength(),$object->getLastModified()); } //6.下载文件 $object = $container->getObject($dirName . 'upload_small_object.txt'); $objectContent = $object->getContent(); $objectContent->rewind(); $stream = $objectContent->getStream(); file_put_contents('D:/123.txt', $stream); //7.删除容器(删除云盘使用者时删除对应云盘) $objects = $container->objectList(); //循环删除每个对象(不支持批删) foreach ($objects as $object) { $object->delete(); } $container->delete();
