PHP Load balancing and automatic expansion configuration example in Tencent Cloud Server API interface docking

Introduction: When using PHP to develop Tencent Cloud Server API interface, load balancing and automatic expansion are very important configurations . This article will give some sample code to help developers better understand and configure these functions.

1. Load balancing configuration

Load balancing is to improve the performance and availability of the system by reasonably allocating requests to different servers. To configure load balancing on Tencent Cloud, you can use the API interface provided by Tencent Cloud. The following is a sample code for creating a load balancing instance:

<?php
require_once 'TencentCloudSdkPhp/autoload.php';

use TencentCloudCommonCredential;
use TencentCloudCommonProfileClientProfile;
use TencentCloudCommonProfileHttpProfile;
use TencentCloudCvmV20170312CvmClient;
use TencentCloudCvmV20170312ModelsLoadBalancer;

$cred = new Credential("your-secret-id", "your-secret-key");
$httpProfile = new HttpProfile();
$httpProfile->setEndpoint("cvm.tencentcloudapi.com");

$clientProfile = new ClientProfile();
$clientProfile->setHttpProfile($httpProfile);
$client = new CvmClient($cred, "ap-guangzhou", $clientProfile);

$req = new LoadBalancer();
$req->LoadBalancerName = "test-balance";
$req->LoadBalancerType = "NORMAL";
$req->ProjectId = "0";
$req->Exclusive = "no";
$req->Forward = "LB";
$req->LoadBalancerVips = [
    "192.168.0.1"
];

$response = $client->CreateLoadBalancer($req);
print_r($response);

?>

In this sample code, you need to replace "your-secret-id" and "your-secret-key" with your Tencent Cloud API key. "ap-guangzhou" is a regional parameter and can be modified according to actual needs.

It should be noted that the result returned by Tencent Cloud's API interface is a string in JSON format, which can be printed out through the "print_r($response)" statement to view the returned detailed information.

2. Automatic expansion configuration

Automatic expansion means that the system automatically adds more server resources according to demand to cope with the number of requests under high load. Tencent Cloud provides an API interface to facilitate automatic expansion configuration. The following is a sample code for creating an automatic expansion configuration:

<?php
require_once 'TencentCloudSdkPhp/autoload.php';

use TencentCloudCommonCredential;
use TencentCloudCommonProfileClientProfile;
use TencentCloudCommonProfileHttpProfile;
use TencentCloudCvmV20170312CvmClient;
use TencentCloudCvmV20170312ModelsAutoScalingGroup;

$cred = new Credential("your-secret-id", "your-secret-key");
$httpProfile = new HttpProfile();
$httpProfile->setEndpoint("cvm.tencentcloudapi.com");

$clientProfile = new ClientProfile();
$clientProfile->setHttpProfile($httpProfile);
$client = new CvmClient($cred, "ap-guangzhou", $clientProfile);

$req = new AutoScalingGroup();
$req->AutoScalingGroupName = "test-group";
$req->DefaultCooldown = 300;
$req->DesiredCapacity = 2;
$req->MaxSize = 5;
$req->MinSize = 1;
$req->ProjectId = 0;
$req->VpcId = "vpc-xxxxxxxx";
$req->LaunchConfigurationId = "as-launch-config-xxxxxxxx";

$response = $client->CreateAutoScalingGroup($req);
print_r($response);

?>

In this sample code, you also need to replace "your-secret-id" and "your-secret-key" with your Tencent Cloud API key. Among them, "vpc-xxxxxxxx" and "as-launch-config-xxxxxxxx" also need to be replaced according to the actual situation.

It should be reminded that the configuration of automatic expansion needs to be coordinated with other services of Tencent Cloud, such as cloud database, cloud monitoring, etc., in order to play a greater role. For specific configuration steps, please refer to Tencent Cloud’s official documentation.

Conclusion:

This article gives a configuration example of load balancing and automatic expansion in Tencent Cloud Server API interface docking. It is hoped that these sample codes can help developers better understand and configure these functions, and make good use of the various API interfaces provided by Tencent Cloud to facilitate developers' work.
