PHP多进程开发与Redis结合实践

原文:https://blog.51cto.com/laok8/2107892?source=drh

业务逻辑介绍:

  1. 用户在 APP 上发帖子,然后存储到 Redis 的 List 列表中
  2. 利用 Linux 的 crontab 定时任务功能,按秒请求执行PHP脚本文件(processNewsRedisList.php)
  3. 调用 redis_process 处理API,进行存储到 Mysql 中

1.发帖子API

public function post_json() { $image = $_FILES['image']; $data = I(); $images = $this->post_upload($image); $data['image'] = $images ? $images : ''; if( count($data) ){ $redis = new Redis(); $data['creation_time'] = time(); //把发过来的帖子存储redis $result = $redis->lpush('news_list', json_encode($data)); // $redis->lpush('news_list', json_encode($data)); // while (TRUE){ // if ($redis->lsize('news_list') > 0){ // $info = $redis->rpop('news_list'); // $info = json_decode($info, true); // $result = $this->_model->news_publish( $info ); // }else { // sleep(1);break; // } // } // $redis->close(); $data['creation_time'] = time(); // $result = $this->_model->news_publish( $data ); if( $result < 1 ){//redis方式 // if( !$result ){//model方式 $this->_data['data'] = ''; $this->_data['error'] = true; $this->_data['message'] = L('_DATABASE_ERROR_'); }else{//success $this->_data['data'] = $result; $this->_data['error'] = false; } } else{ $this->_data['data'] = ''; $this->_data['error'] = true; $this->_data['message'] = L('_Invalid_Parameters_'); } $this->response($this->_data); }

 
 

2.processNewsRedisList.php

<?php
/**
*检查队列中帖子,并把帖子插入数据库表中
*/

function worker() { //再次克隆出子进程 $pid = pcntl_fork(); if ( $pid == -1 ) { exit('fork error'); } if ( $pid == 0 ) { $redis = new Redis(); $redis->connect('127.0.0.1', 7200); //业务逻辑代码 while(true) {//sleep(5); if( $redis->lsize('news_list') > 0 ){ $info = $redis->rpop('news_list'); $info = json_decode($info, TRUE); //使用curl调用API接口 $uri = "http://*.*.*.*:*/api.zmartec/News/redis_process"; $data = $info; $ch = curl_init(); curl_setopt($ch, CURLOPT_URL, $uri); curl_setopt($ch, CURLOPT_POST, 1); curl_setopt($ch, CURLOPT_HEADER, 0); curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); curl_setopt($ch, CURLOPT_POSTFIELDS, $data); $result = curl_exec($ch); curl_close($ch); } else { sleep(1);//队列中没有任务的时候,睡眠1s,让出cpu给其它进程 } } $redis->close(); } } /** *子进程,负责设置子进程为领导小组 * *并调用处理函数,处理任务 */ function children() { $sid = posix_setsid(); echo $sid; for( $i = 0; $i < 2; $i++ ) { worker(); } } //克隆子进程,返回子进程的进程id $pid = pcntl_fork(); if ( $pid == -1 ) { exit('fork error'); } if ( $pid == 0 ) { children(); }else{ exit('parent exit'); } ?>

 
 

3.存储帖子到 Mysql

thinkphp 3.2框架:
public function redis_process() { $data = $_POST; if ($this->_model->news_publish($data)) { return true; } esle { return false; } } public function news_publish( $data ) { try{ return M('news')->add($data); }catch(Exception $ex){ return FALSE; } }
