SLB load balancing and CDN acceleration configuration example in PHP Huawei Cloud API interface docking

When docking PHP Huawei Cloud API interface, it is often necessary to consider the configuration of load balancing and CDN acceleration. This article will give an example of how to configure SLB load balancing and CDN acceleration using PHP code.

1. SLB load balancing configuration example

SLB (Server Load Balancer) is a high-availability load balancing service provided by Huawei Cloud. It forwards requests from users to multiple back-end servers to balance server load and improve website availability and performance.

The following is an example of configuring SLB load balancing using PHP code:

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

use OpenStackOpenStack;

$credentials = [
    'authUrl' => 'https://iam.cn-north-1.myhuaweicloud.com/v3',
    'region'  => 'cn-north-1',
    'user'    => [
        'password' => [
            'user'     => [
                'id'       => 'your_user_id',
                'password' => 'your_user_password',
            ],
            'domain' => [
                'id' => 'your_domain_id',
            ],
        ],
    ],
    'scope'   => [
        'project' => [
            'id' => 'your_project_id',
        ],
    ],
];

$openstack = new OpenStack($credentials);

// 创建负载均衡器
$loadBalancer = $openstack->loadBalancerV2()
    ->create([
        'name'         => 'my_load_balancer',
        'description'  => 'My Load Balancer',
        'vip_subnet_id' => 'your_vip_subnet_id',
    ]);

echo 'Load Balancer created: ' . $loadBalancer->id . PHP_EOL;
?>

In the code, we first use the OpenStack SDK to load the required dependencies and configuration. We then authenticate using the provided authentication information. Next, we create a load balancer using the loadBalancerV2() method and pass in the necessary parameters such as name, description, and VIP subnet ID. Finally, we output the ID of the load balancer.

2. CDN acceleration configuration example

CDN (Content Delivery Network) is a service used to accelerate static resources. It caches the static resources of the website to globally distributed nodes so that users can obtain the fastest resource response from the nodes closest to them.

The following is an example of configuring CDN acceleration using PHP code:

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

use OpenStackOpenStack;

$credentials = [
    'authUrl' => 'https://iam.cn-north-1.myhuaweicloud.com/v3',
    'region'  => 'cn-north-1',
    'user'    => [
        'password' => [
            'user'     => [
                'id'       => 'your_user_id',
                'password' => 'your_user_password',
            ],
            'domain' => [
                'id' => 'your_domain_id',
            ],
        ],
    ],
    'scope'   => [
        'project' => [
            'id' => 'your_project_id',
        ],
    ],
];

$openstack = new OpenStack($credentials);

// 创建CDN加速域名
$domain = $openstack->cdn()
    ->createDomain([
        'domain_name'          => 'your_domain_name',
        'business_type'        => 'web',
        'source_type'          => 'ipaddr',
        'sources'              => [
            [
                'ip_or_domain' => 'your_source_ip_or_domain',
                'origin_port'  => 80,
            ],
        ],
        'domain_origin_host'   => 'your_origin_host',
        'https_status'         => 'on',
        'force_redirect_https' => 'off',
        'service_area'         => 'mainland_china',
        'detail_rule'          => [
            [
                'rule_type'         => 'suffix',
                'content'           => 'js',
                'follow_status_code' => 'follow_302',
                'origin_type'       => 'consensus',
                'origin_content'    => 'http',
                'ccd_enabled'       => 'off',
            ],
        ],
    ]);

echo 'CDN domain created: ' . $domain->domain_name . PHP_EOL;
?>

In the code, we also load the required dependencies and configuration first, and then authenticate. Next, we use the cdn() method to create a CDN accelerated domain name and pass in the necessary parameters, such as domain name, business type, origin site type, and origin site information. Finally, we output the created CDN accelerated domain name.

The above is an example of using PHP code to configure SLB load balancing and CDN acceleration. By connecting to the Huawei Cloud API interface, we can easily achieve load balancing and accelerate the response speed of the website's static resources. I hope this example can help developers who are connecting to the PHP Huawei Cloud API interface.
