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"
     }
   }

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';

// 创建一个Worker实例
$worker = new Worker('text://0.0.0.0:2346');

// 设置进程数
$worker->count = 4;

// 处理接收到的消息
$worker->onMessage = function($connection, $data)
{
    // 将消息存储到Redis队列
    $redis = new Redis();
    $redis->connect('127.0.0.1', 6379);
    $redis->lpush('message_queue', $data);
};

// 启动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
// 从Redis队列中获取消息
$redis = new Redis();
$redis->connect('127.0.0.1', 6379);
$message = $redis->rpop('message_queue');

// 执行相关操作
// ...
?>

7. Run the program:

Start the message queue service: execute the command
1. php myqueue/Applications/MessageServer/Index.php start；
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.
