How to use Workerman to implement a distributed log analysis system

Overview:
With the rapid development of Internet technology and the rise of big data, log analysis has become an important issue for enterprises An important part of operations and system debugging. The distributed log analysis system can help system administrators better understand and monitor the operating status of the system, discover abnormalities and bottlenecks in a timely manner, and make corresponding adjustments. Workerman is a high-performance framework for PHP. It has the characteristics of asynchronous non-blocking and multi-process high concurrency. It is very suitable for developing distributed log analysis systems. This article will introduce how to use Workerman to build a simple distributed log analysis system, and provide specific code examples.

1. Environment preparation
1. Install PHP: Workerman is a PHP framework, so you need to install the PHP running environment first. We can use apt-get to install PHP (the installation method may be different depending on the specific system):

sudo apt-get install php-fpm

2. Install Workerman: Workerman can be installed through Composer. We first need to install Composer. Use the following command to install Composer:

curl -sS https://getcomposer.org/installer | php
sudo mv composer.phar /usr/local/bin/composer

Then, execute the following command in the project directory to install Workerman:

composer require workerman/workerman

3. Install Redis: We use Redis as the data storage of the distributed log analysis system . You can install Redis through the following command:

sudo apt-get install redis-server

2. Build a distributed log analysis system
First, we need to determine the architecture and process of the distributed log analysis system. In our system, there are the following roles:

1. LogProducer: Log producer, responsible for generating system logs and sending them to log consumers.
2. LogConsumer: Log consumer, receives logs sent by log producers and stores them in Redis.
3. LogAnalyzer: Log analyzer, regularly reads logs from Redis and analyzes them.

The following is a specific code example:

1. LogProducer.php

   <?php
   
   use WorkermanWorker;
   use WorkermanConnectionAsyncTcpConnection;
   
   require_once __DIR__.'/vendor/autoload.php';
   
   // 连接日志消费者
   $producer = new AsyncTcpConnection('text://127.0.0.1:1234');
   $producer->onConnect = function($producer) {
    $producer->send("Hello, LogConsumer!");
   };
   $producer->onMessage = function($producer, $data) {
    // 产生日志
    $log = generateLogData();
    // 发送日志给日志消费者
    $producer->send($log);
   };
   // 运行日志生产者
   Worker::runAll();
   
   function generateLogData()
   {
    // 生成日志数据的代码
    // ...
    return $log;
   }

2. LogConsumer.php

   <?php
   
   use WorkermanWorker;
   use WorkermanConnectionAsyncTcpConnection;
   
   require_once __DIR__.'/vendor/autoload.php';
   
   // 连接Redis
   $redis = new AsyncTcpConnection('tcp://127.0.0.1:6379');
   $redis->onConnect = function($redis) {
    $redis->send("AUTH yourpassword"); // 如果Redis服务器设置了密码，请替换成实际的密码
   };
   $redis->onMessage = function($redis, $data) {
    // 存储日志到Redis
    $redis->send("LPUSH log_queue $data");
   };
   $redis->connect();
   
   // 运行日志消费者
   Worker::runAll();

3. LogAnalyzer.php

   <?php
   
   use WorkermanWorker;
   use WorkermanConnectionAsyncTcpConnection;
   
   require_once __DIR__.'/vendor/autoload.php';
   
   // 连接Redis
   $redis = new AsyncTcpConnection('tcp://127.0.0.1:6379');
   $redis->onConnect = function($redis) {
    $redis->send("AUTH yourpassword"); // 如果Redis服务器设置了密码，请替换成实际的密码
   };
   $redis->onMessage = function($redis, $data) {
    // 从Redis中读取日志并进行分析
    $redis->send("RPOP log_queue 10");
    // 进行日志分析的代码
   };
   $redis->connect();
   
   // 运行日志分析器
   Worker::runAll();

So far, we have completed the construction of a simple distributed log analysis system.

Summary:
This article introduces how to use Workerman to build a distributed log analysis system. Through the distributed log analysis system, we can better monitor the operating status of the system and discover and solve problems in a timely manner. At the same time, Workerman's high-performance features also enable the system to cope with high concurrency and large data volumes. I hope this article will be helpful for developing a distributed log analysis system using Workerman.
