Laravel Redis键过期，supervisor 进程管理实现15分钟取消订单

1、自动取消订单考虑到Redis键过期进行处理，修改Redis配置文件，并重启Redis

notify-keyspace-events "Ex"

2、Laravel安装Redis扩展

composer require predis/predis

3、Laravel配置Redis连接

这里不详细介绍，.env  config\database.php 配置即可

4、建立任务文件

php artisan make:command OrderCloseExpireListen

app\Console\Commands\OrderCloseExpireListen

<?php

namespace App\Console\Commands;

use Illuminate\Console\Command;
use Illuminate\Support\Facades\Redis;
use Illuminate\Support\Facades\Log;
class OrderCloseExpireListen extends Command
{
/**
 * The name and signature of the console command.
 *
 * @var string
 */
protected $signature = 'orderClose:expire';

/**
 * The console command description.
 *
 * @var string
 */
protected $description = '15分钟自动取消订单';

/**
 * Create a new command instance.
 *
 * @return void
 */
public function __construct()
{
    parent::__construct();
}

/**
 * @param $number
 * @return false|string
 */
public function str_after($number){
    $str = substr($number,strripos($number,":")+1);
    return $str;
}

/**
 * @param $number
 * @return false|string
 */
public function str_before($number){
    $str = substr($number,0,strrpos($number,":"));
    return $str;
}


/**
 * Execute the console command.
 *
 * @return int
 */
public function handle()
{
    $db = config('database.redis.default.database', 0); // 监听的数据库
    $pattern = '__keyevent@'. $db . '__:expired'; // 监听事件:键过期事件
    Redis::subscribe([$pattern], function ($channel) { // 订阅键过期事件，$channel为返回的键名
        $key_type = $this->str_before($channel);
		if($key_type == 'ORDER_CLOSE_ID'){
		    $order_id = $this->str_after($channel);    // 获取订单ID
            $order = (new Order())->getOne(['id'=>(int)$order_id]);
			//取消订单业务逻辑
		}           
    });
}

}

4、执行

php artisan orderClose:expire
使用supervisor进程管理
centos 安装： yum install supervisor 
启动服务：supervisord -c /etc/supervisord.conf
修改配置：vim /etc/supervisord.conf
files = supervisord.d/\*.conf // 注意：编译器问题用的时候去掉\
cd /etc/supervisord.d/
vim orderClose.conf

[program:laravel-worker]
process_name=%(program_name)s_%(process_num)02d
command=php /项目目录/artisan orderClose:expire
autostart=true
autorestart=true
user=root
numprocs=8
redirect_stderr=true
stderr_logfile=/etc/supervisord.d/log/ossoffical.err.log #错误日志文件
stdout_logfile=/etc/supervisord.d/log/ossoffical.out.log #输出日志文件

supervisorctl reload  //重新加载配置文件

5、存Redis

Redis::set('ORDER_CLOSE_ID:1', 1, 'EX', 900); // 设置ORDER_CLOSE_ID:1这个键15分钟后过期
