Develop a highly available real-time log analysis system based on Workerman

Introduction:
In today's Internet era, real-time log analysis systems play an important role in enterprise operations and decision-making. Crucial role. With the continuous expansion of business scale, the amount of log data is becoming larger and larger, and traditional log analysis methods can no longer meet the demand. This article will introduce how to develop a highly available real-time log analysis system based on PHP and use Workerman as the underlying framework.

1. Introduction to Workerman
Workerman is a high-performance, event-driven network framework for PHP. It supports TCP/UDP long connections and can be used to build real-time communication applications, game servers, and high-performance background services. Workerman has the characteristics of low resource consumption, high concurrency and high stability, and is very suitable for building a real-time log analysis system.

2. Project structure and functional modules

1. Project structure
   Organize the project structure in the MVC (Model-View-Controller) mode to maintain the maintainability and accessibility of the code Scalability.

log_analysis
 |- app
 |  |- Controller
 |  |- Model
 |  |- View
 |- config
 |- logs
 |- public
    |- index.php
 |- vendor
 |- worker

2. Function module
   (1) Data receiving module: Use Workerman to create a TCP service, listen to the specified port, and receive log data in real time.

// worker/LogReceiver.php

use WorkermanWorker;

// 创建一个Worker监听指定端口
$receiver = new Worker('tcp://0.0.0.0:5678');

// 收到数据时处理
$receiver->onMessage = function($connection, $data) {
  // 对接收到的日志数据进行处理，存储到数据库或发送到消息队列等
  // ...
};

// 启动Worker
Worker::runAll();

(2) Data processing module: Use queues (such as Redis) to save received log data, and use multiple Worker consumption queues for data processing and analysis.

// worker/LogProcessor.php

use WorkermanWorker;
use WorkermanLibTimer;

// 创建一个Worker监听指定端口
$processor = new Worker();

// 进程启动时设置定时器，定时从队列中取出数据进行处理
$processor->onWorkerStart = function($worker) {
  Timer::add(0.1, function() {
    // 从队列中取出数据进行处理
    // ...
  });
};

// 启动Worker
Worker::runAll();

(3) Data display module: Use Websocket to push data to the front end and display analysis results in real time.

// worker/LogPusher.php

use WorkermanWorker;

// 创建一个Worker监听指定端口
$pusher = new Worker('websocket://0.0.0.0:8181');

// 接收到客户端连接时处理
$pusher->onConnect = function($connection) {
  // 将连接保存到集合中
  // ...
};

// 收到数据时处理
$pusher->onMessage = function($connection, $data) {
  // 处理前端发送过来的数据
  // ...
};

// 断开连接时处理
$pusher->onClose = function($connection) {
  // 从集合中移除断开连接的客户端
  // ...
};

// 启动Worker
Worker::runAll();

3. System deployment and operation

1. System deployment
   (1) Install the PHP environment and Workerman
   (2) Configure relevant parameters, such as database connection information, Queue connection information, etc.
   (3) Start the data receiving module, data processing module and data display module
2. System operation
   Start all workers to maintain the stable operation of the system. The data receiving module continuously receives log data, the data processing module takes out data from the queue for processing, and the data display module pushes data to the front end in real time through Websocket.

Conclusion:
A highly available real-time log analysis system developed based on Workerman can meet the needs of large-scale business, analyze log data in real time, and provide real-time operational decision-making reference. At the same time, Workerman's high performance and event-driven features also enable the system to have high concurrency and high stability.
