免费行情软件app网站红色,宣传片拍摄大纲,做网站维护的人叫啥,住房和城乡建设部服务门户一、概念
1、项目
一个账号有唯一的项目#xff0c;所有虚拟机都在project里面建。
2、计算引擎
虚拟机资源。 二、创建方式
1、页面控制台
2、gcloud命令行
3、REST API
4、SDK 三、Java SDK
1、创建API服务凭据#xff0c;并下载P12文件 2、Maven dependency所有虚拟机都在project里面建。

3、计算引擎会话 public static Compute getCompute() {String appName your app name;String serviceAccountId your service account id;String proxyHost my.proxy.com;String proxyPort 8090;//国内需要代理System.setProperty(com.google.api.client.should_use_proxy,true);System.setProperty(https.proxyHost,proxyHost);System.setProperty(https.proxyPort,proxyPort);try {HttpTransport transport new NetHttpTransport.Builder().trustCertificates(GoogleUtils.getCertificateTrustStore()).build();JacksonFactory jsonFactory JacksonFactory.getDefaultInstance();ListString scopes new ArrayList();// Set Google Cloud Storage scope to Full Control.scopes.add(ComputeScopes.DEVSTORAGE_FULL_CONTROL);// Set Google Compute Engine scope to Read-write.scopes.add(ComputeScopes.COMPUTE);// Authenticate using Google Application Default Credentials.GoogleCredential credential new GoogleCredential.Builder().setTransport(transport).setJsonFactory(jsonFactory).setServiceAccountId(serviceAccountId).setServiceAccountScopes(scopes).setServiceAccountPrivateKeyFromP12File(List.class.getResourceAsStream(/my-rojectId-384742064.p12)).build();// Create Compute Engine object for listing instances.Compute compute new Compute.Builder(transport, jsonFactory, credential).setApplicationName(appName).build();return compute;} catch (GeneralSecurityException | IOException e) {e.printStackTrace();}return null;}
4、创建虚拟机 public static void create() {Compute compute getCompute();String googleDomain https://www.googleapis.com;String region asia-south1;String zone asia-south1-a;String network first-network;String subNet first-subnet;String imageId projects/debian-cloud/global/images/debian-9-stretch-v20190326;String osDiskName first-os-disk;Integer osDiskSize 30;String osDiskType pd-standard;String vmName first-vm;String vmType n1-standard-1;String publicIpName first-public-ip;String dataDiskName first-data-disk;String dataDiskType pd-standard;Long dataDiskSize 200L;String projectId your projectId;try {Instance instance new Instance();instance.setName(vmName);instance.setZone(zone);instance.setMachineType(zones/ zone /machineTypes/ vmType);NetworkInterface networkInterface new NetworkInterface();networkInterface.setNetwork(global/networks/ network);networkInterface.setSubnetwork(regions/ region /subnetworks/ subNet);ListAccessConfig configs new ArrayList();AccessConfig config new AccessConfig();String NETWORK_INTERFACE_CONFIG ONE_TO_ONE_NAT;config.setType(NETWORK_INTERFACE_CONFIG);config.setName(publicIpName);config.setNetworkTier(PREMIUM);configs.add(config);networkInterface.setAccessConfigs(configs);instance.setNetworkInterfaces(Collections.singletonList(networkInterface));ListAttachedDisk attachedDisks new ArrayList();//系统盘AttachedDisk osDisk new AttachedDisk();osDisk.setBoot(true);osDisk.setAutoDelete(true);osDisk.setType(PERSISTENT);AttachedDiskInitializeParams osParams new AttachedDiskInitializeParams();osParams.setDiskName(osDiskName);osParams.setSourceImage(imageId);osParams.setDiskType(zones/ zone /diskTypes/ osDiskType);osParams.setDiskSizeGb(osDiskSize.longValue());osDisk.setInitializeParams(osParams);attachedDisks.add(osDisk);//数据盘AttachedDisk dataDisk new AttachedDisk();dataDisk.setBoot(false);dataDisk.setAutoDelete(true);dataDisk.setType(PERSISTENT);AttachedDiskInitializeParams dataParams new AttachedDiskInitializeParams();// Assign the Persistent Disk the same name as the VM Instance.osParams.setDiskName(dataDiskName);osParams.setDiskType(zones/ zone /diskTypes/ dataDiskType);osParams.setDiskSizeGb(dataDiskSize);dataDisk.setInitializeParams(dataParams);attachedDisks.add(dataDisk);instance.setDisks(attachedDisks);ServiceAccount account new ServiceAccount();account.setEmail(default);ListString scopes new ArrayList();scopes.add(googleDomain /auth/devstorage.full_control);scopes.add(googleDomain /auth/compute);account.setScopes(scopes);instance.setServiceAccounts(Collections.singletonList(account));//ssh串行接口/*Metadata.Items items new Metadata.Items();items.setKey(serial-port-enable);items.setValue(true);Metadata metadata new Metadata();metadata.setItems(Arrays.asList(items));instance.setMetadata(metadata);*/Compute.Instances.Insert insert compute.instances().insert(projectId, zone, instance);Operation operation insert.execute();operation blockUntilComplete(compute, operation, projectId,5 * 60 * 1000);if (operation ! null operation.getError() ! null)throw new RuntimeException(创建失败);} catch (Exception ex) {ex.printStackTrace();}}private static Operation blockUntilComplete(Compute compute, Operation operation, String projectId, long timeoutMil) throws Exception {long start System.currentTimeMillis();final long pollInterval 3 * 1000;String zone operation.getZone(); // null for global/regional operationsif (zone ! null) {String[] bits zone.split(/);zone bits[bits.length - 1];}String region operation.getRegion();if (region!null){String[] bits region.split(/);region bits[bits.length - 1];}String status operation.getStatus();String opId operation.getName();while (operation ! null !status.equals(DONE)) {Thread.sleep(pollInterval);long elapsed System.currentTimeMillis() - start;if (elapsed timeoutMil) {throw new InterruptedException(Timed out waiting for operation to complete);}if (zone ! null) {Compute.ZoneOperations.Get get compute.zoneOperations().get(projectId, zone, opId);operation get.execute();} else if(region!null){Compute.RegionOperations.Get get compute.regionOperations().get(projectId, region, opId);operation get.execute();}else {Compute.GlobalOperations.Get get compute.globalOperations().get(projectId, opId);operation get.execute();}if (operation ! null) {status operation.getStatus();}}return operation;}5、删除虚拟机
public static void delete() {String zone asia-south1-a;String vmName first-vm;String projectId your projectId;Compute compute getCompute();try {Compute.Instances.Delete delete compute.instances().delete(projectId, zone, vmName);Operation operation delete.execute();operation blockUntilComplete(compute, operation, projectId,5 * 60 * 1000);if (operation ! null operation.getError() ! null)throw new RuntimeException(删除失败);}catch (Exception ex){throw new RuntimeException(ex);}}
6、查询虚拟机 public static void getVm(){String zone asia-south1-a;String vmName first-vm;String projectId your projectId;Compute compute getCompute();try {Compute.Instances.Get get compute.instances().get(projectId, zone,vmName);Instance instance get.execute();//STAGING, RUNNING, STOPPING, STOPPED, SUSPENDING, SUSPENDED, and TERMINATEDString status instance.getStatus();} catch (IOException e) {e.printStackTrace();}}
7、停止启动操作
public static void op() {String zone asia-south1-a;String vmName first-vm;String projectId your projectId;Compute compute getCompute();try {Compute.Instances.Stop stop compute.instances().stop(projectId, zone,vmName);Operation operation stop.execute();if (operation ! null operation.getError() ! null)throw new RuntimeException(停止失败);Compute.Instances.Start start compute.instances().start(projectId, zone,vmName);Operation startOp start.execute();if (startOp ! null startOp.getError() ! null)throw new RuntimeException(启动失败);}catch (Exception ex){throw new RuntimeException(ex);}}
8、设置静态公网IP public static void modify() {String region asia-south1;String zone asia-south1-a;String vmName first-vm;String projectId your projectId;Compute compute getCompute();try {Compute.Instances.Get get compute.instances().get(projectId, zone, vmName);Instance instance get.execute();for (NetworkInterface n : instance.getNetworkInterfaces()) {for (AccessConfig config : n.getAccessConfigs()) {if (!Strings.isNullOrEmpty(config.getNatIP())) {Address address new Address();address.setName(config.getName());address.setAddress(config.getNatIP());Compute.Addresses.Insert inset compute.addresses().insert(projectId, region, address);Operation op inset.execute();if (op ! null op.getError() ! null)throw new RuntimeException(绑定公网IP失败);}}}} catch (Exception ex) {ex.printStackTrace();}} 四、REST API
使用OAuth 2.0访问Google API
Compute Engine API
保留静态外部 IP 地址
保留静态内部 IP 地址
资源引用实例与实例组、实例组与负载均衡等引用关系· 创建实例
