Laravel uses swoole to monitor redis

Before you start, please make sure that redis is installed correctly and running normally.

Laravel code

Create a new RedisTest event in the App\Events directory

<?php
namespace App\Events;
use Illuminate\Broadcasting\Channel;
use Illuminate\Queue\SerializesModels;
use Illuminate\Broadcasting\PrivateChannel;
use Illuminate\Broadcasting\PresenceChannel;
use Illuminate\Foundation\Events\Dispatchable;
use Illuminate\Broadcasting\InteractsWithSockets;
use Illuminate\Contracts\Broadcasting\ShouldBroadcast;
class RedisTest
{
    use Dispatchable, InteractsWithSockets, SerializesModels;
    public $message;
    /**
    * Create a new event instance.
    *
    * @return void
    */
    public function __construct($message)
    {
        $this->message = $message;
    }
    /**
    * Get the channels the event should broadcast on.
    *
    * @return \Illuminate\Broadcasting\Channel|array
    */
    public function broadcastOn()
    {
        return new PrivateChannel(&#39;channel-name&#39;);
    }
}

App\Listeners\RedisTestListener listening event code

<?php
namespace App\Listeners;
use App\Events\RedisTest;
use Illuminate\Queue\InteractsWithQueue;
use Illuminate\Contracts\Queue\ShouldQueue;
use Illuminate\Support\Facades\Log;
class RedisTestListener
{
    /**
    * Create the event listener.
    *
    * @return void
    */
    public function __construct()
    {
        //
    }
    /**
    * Handle the event.
    *
    * @param  RedisTest  $event
    * @return void
    */
    public function handle(RedisTest $event)
    {
        $message = $event->message;
        Log::info(&#39;the message received from subscribed redis channel msg_0: &#39;.$message);
    }
}

Copy after login

App\Providers\EventServiceProvider Register event/listening relationship

protected $listen = [
        &#39;App\Events\RedisTest&#39; => [
            &#39;App\Listeners\RedisTestListener&#39;,
        ],
    ];

Copy after login

Listening command

App\Console\Commands\RedisSubscribe The code is as follows

<?php
namespace App\Console\Commands;
use Illuminate\Console\Command;
use swoole_redis;
use Illuminate\Support\Facades\Event;
use App\Events\RedisTest;
class RedisSubscribe extends Command
{
    /**
    * The name and signature of the console command.
    *
    * @var string
    */
    protected $signature = &#39;redis:subscribe&#39;;
    /**
    * The console command description.
    *
    * @var string
    */
    protected $description = &#39;deamon process to subscribe redis broadcast&#39;;
    /**
    * Create a new command instance.
    *
    * @return void
    */
    public function __construct()
    {
        parent::__construct();
    }
    /**
    * Execute the console command.
    *
    * @return mixed
    */
    public function handle()
    {
        $client = new swoole_redis;
        $client->on(&#39;message&#39;, function (swoole_redis $client, $result) {
            var_dump($result);
            static $more = false;
            if (!$more and $result[0] == &#39;message&#39;)
            {
                echo "trigger Event RedisTest\n";
                Event::fire(new RedisTest($result[2]));
            }
        });
        $client->connect(&#39;127.0.0.1&#39;, 6379, function (swoole_redis $client, $result) {
            echo "connect\n";
            $client->subscribe(&#39;msg_0&#39;);
        });
    }
}

directory=/home/bella/Downloads/lnmp/echo1.0/echo
user=bella
