Workerman Development Practice: Implementing a Distributed Message Queuing System

Introduction:
In modern applications, the message queue system is an important component used to implement asynchronous communication between applications . In a high-concurrency environment, the message queue system can play a role in peak-shaving and valley-filling, improving the stability and performance of the overall system. This article will introduce how to use the Workerman framework to develop a distributed message queue system and provide relevant code examples.

1. Environment preparation:
Before starting, we need to prepare the following environment:

  1. PHP7.0 and above;
  2. composer tool;
  3. Workerman framework;
  4. Redis database.

2. Project structure:
First create a project directory with the following directory structure:

  • myqueue

    • Applications

      • MessageServer

        • Index.php

        • config

          • config.php
    • ##Libraries

        Workerman
      • vendor
    • composer.json
3. Installation dependencies:

  1. Composer.json in the myqueue directory Add the following dependencies to the file: 

    {
  "require": {
 "workerman/workerman": ">=3.5"
  }
}

    2. Execute the command
  2. composer install to install the Workerman framework and its dependencies.
4. Write code:

Create the Index.php file in the
myqueue/Applications/MessageServer directory to start the message queue service: 

<?php
use WorkermanWorker;
require_once __DIR__ . '/../../Libraries/Workerman/Autoloader.php';

// 創(chuàng)建一個Worker實例
$worker = new Worker('text://0.0.0.0:2346');

// 設(shè)置進程數(shù)
$worker->count = 4;

// 處理接收到的消息
$worker->onMessage = function($connection, $data)
{
    // 將消息存儲到Redis隊列
    $redis = new Redis();
    $redis->connect('127.0.0.1', 6379);
    $redis->lpush('message_queue', $data);
};

// 啟動Worker
Worker::runAll();
?>

Create the config.php file in the

myqueue/Applications/MessageServer/config directory to configure Redis database information: 

<?php
return array(
    'redis_host' => '127.0.0.1',
    'redis_port' => 6379,
);
?>

5. Use the message queue:

In the application , we can use the following code to send messages to the message queue: 

<?php
$message = 'Hello, Workerman!';
$address = '127.0.0.1:2346';

$socket = stream_socket_client("tcp://$address");
fwrite($socket, $message);
fclose($socket);
?>

6. Consume messages:

Create a consumer script to obtain messages from the message queue and perform related operations. 

<?php
// 從Redis隊列中獲取消息
$redis = new Redis();
$redis->connect('127.0.0.1', 6379);
$message = $redis->rpop('message_queue');

// 執(zhí)行相關(guān)操作
// ...
?>

7. Run the program:

    Start the message queue service: execute the command
  1. php myqueue/Applications/MessageServer/Index.php start；
    2. Start the consumer script: execute the command
  2. php consumer.php.
8. Summary:

This article introduces how to use the Workerman framework to develop a distributed message queue system and achieve asynchronous communication by storing messages in the Redis queue. In this way, we can implement message processing in a high-concurrency environment and improve the performance and stability of the system. Developers can further improve and expand the message queue system based on specific needs.
