PHP implements open source MinIO distributed object storage

With the development of cloud computing and big data technology, more and more enterprises and organizations are beginning to pay attention to the issues of data storage and processing. Traditional storage solutions are obviously unable to meet the needs of modern technology, so distributed object storage has become a topic of great concern.

The core idea of ​​distributed object storage is to store data dispersedly on multiple nodes, and achieve more efficient and safer data management through intelligent load balancing and data backup. In the open source field, MinIO is one of the highly respected distributed object storage implementation solutions. This article will introduce how to use PHP technology to implement distributed object storage based on MinIO.

1. Introduction to MinIO

MinIO is an open source distributed object storage system based on the Amazon S3 protocol. MinIO is designed with high performance, ease of use and scalability in mind. Its core component is the MinIO server, which is a binary executable file written in Go language and can run on a variety of operating systems such as Linux, Windows and MacOS.

MinIO is a lightweight object storage system, very suitable for storing unstructured data, such as pictures, audio, video, etc. MinIO also supports data encryption to ensure user data security.

2. Use of MinIO

To use MinIO, you first need to download and install the MinIO server. MinIO server can be downloaded from the official website or installed through the package management tool.

After the installation is complete, we can start the MinIO server through the following command:

$ ./minio server /data

Among them, /data is the default data storage directory of the MinIO server. After startup, we can access the MinIO server through the following methods:

$ mc ls myminio/

where, myminio is the access link to the MinIO server.

3. Using MinIO in PHP

We can use PHP language to access the MinIO server. PHP provides S3 SDK, which can easily implement distributed object storage based on the Amazon S3 protocol.

To use S3 SDK, you first need to install Composer. Composer is a package management tool for PHP that can help us install and manage dependencies. Next, we use Composer to install the AWS PHP SDK:

$ composer require aws/aws-sdk-php

After the installation is complete, we can use the following code to access the MinIO server:

require 'vendor/autoload.php';

use AwsS3S3Client;
use AwsExceptionAwsException;

$s3 = new S3Client([
    'version' => 'latest',
    'region'  => 'us-east-1',
    'endpoint' => 'http://localhost:9000',
    'credentials' => [
        'key'    => 'minioaccesskey',
        'secret' => 'miniosecretkey',
    ],
]);

$bucket = 'mybucket';

try {
    $s3->createBucket(['Bucket' => $bucket]);
} catch (AwsException $e) {
    echo "Error:
";
    echo $e->getMessage();
}

$key = 'myobject';
$body = 'Hello, MinIO!';

try {
    $result = $s3->putObject([
        'Bucket' => $bucket,
        'Key'    => $key,
        'Body'   => $body,
    ]);

    echo "Object created: ";
    echo $result['ObjectURL'];
} catch (AwsException $e) {
    echo "Error:
";
    echo $e->getMessage();
}

The above code implements object creation based on the S3 protocol , we can see the storage file of this object in MinIO's data storage directory.

4. High availability of MinIO

One of the characteristics of MinIO is its scalability. We can form multiple MinIO servers into a cluster to achieve higher availability and performance.

In the MinIO cluster, different MinIO servers play different roles. Among them, some MinIO servers are selected as leaders and are responsible for coordinating data reading and writing, while other MinIO servers are added to the cluster as followers.

We can use the following command to form multiple MinIO servers into a cluster:

$ ./minio server http://server1:9000 http://server2:9000 http://server3:9000

The above command will form server1, server2 and server3 into a MinIO cluster to achieve distributed storage and load balancing of data. .

5. Conclusion

MinIO is a distributed object storage implementation solution based on the Amazon S3 protocol, which has the characteristics of high performance, ease of use and scalability. By accessing MinIO server through PHP language, we can easily implement distributed object storage functions.

In actual application scenarios, we can form a cluster with multiple MinIO servers to improve system availability and performance. Through the combination of MinIO and PHP technology, we can build an efficient and secure distributed storage system to meet the data management needs of modern applications.
