Laravel+pm2+rabbitmq创建高性能队列，并用pm2进行队列监控
简介
之前一直有研究rabbitmq，而且也用过supervisor，lz感觉实在是太难用了，真的是，老断，所以果断弃用，而改用pm2，一方面便于监控，另一方面，看起来也很友好，好了，废话不多说，直接上代码；
操作步骤：
一．你肯定要有laravel框架，这里如何安装就不赘述了；
二．安装pm2，在此以centos为例：使用npm全局安装npm i pm2 -g
[if !supportLists]三．[endif]安装rabbitmq，具体安装教程请参考文档：https://www.linuxprobe.com/install-rabbitmq-on-centos-7.html
[if !supportLists]四．[endif]
好了一切准备就绪，然后laravel里面配置：
1、Composer安装laravel-queue-rabbitmqcomposer require vladimir-yuldashev/laravel-queue-rabbitmq2、在config/app.php文件中，providers中添加：VladimirYuldashev\LaravelQueueRabbitMQ\LaravelQueueRabbitMQServiceProvider::class,3、在app/config/queue.php配置文件中的connections数组中加入以下配置
'rabbitmq' => [
'driver' => 'rabbitmq',
'dsn' => env('RABBITMQ_DSN', null),
/*
* Could be one a class that implements \Interop\Amqp\AmqpConnectionFactory for example:
* - \EnqueueAmqpExt\AmqpConnectionFactory if you install enqueue/amqp-ext
* - \EnqueueAmqpLib\AmqpConnectionFactory if you install enqueue/amqp-lib
* - \EnqueueAmqpBunny\AmqpConnectionFactory if you install enqueue/amqp-bunny
*/
'factory_class' => Enqueue\AmqpLib\AmqpConnectionFactory::class,
'host' => env('RABBITMQ_HOST', '127.0.0.1'),
'port' => env('RABBITMQ_PORT', 5672),
'vhost' => env('RABBITMQ_VHOST', '/'),
'login' => env('RABBITMQ_LOGIN', 'guest'),
'password' => env('RABBITMQ_PASSWORD', 'guest'),
'queue' => env('RABBITMQ_QUEUE', 'default'),
'options' => [
'exchange' => [
'name' => env('RABBITMQ_EXCHANGE_NAME'),
/*
* Determine if exchange should be created if it does not exist.
*/
'declare' => env('RABBITMQ_EXCHANGE_DECLARE', true),
/*
* Read more about possible values at https://www.rabbitmq.com/tutorials/amqp-concepts.html
*/
'type' => env('RABBITMQ_EXCHANGE_TYPE', \Interop\Amqp\AmqpTopic::TYPE_DIRECT),
'passive' => env('RABBITMQ_EXCHANGE_PASSIVE', false),
'durable' => env('RABBITMQ_EXCHANGE_DURABLE', true),
'auto_delete' => env('RABBITMQ_EXCHANGE_AUTODELETE', false),
'arguments' => env('RABBITMQ_EXCHANGE_ARGUMENTS'),
],
'queue' => [
/*
* Determine if queue should be created if it does not exist.
*/
'declare' => env('RABBITMQ_QUEUE_DECLARE', true),
/*
* Determine if queue should be binded to the exchange created.
*/
'bind' => env('RABBITMQ_QUEUE_DECLARE_BIND', true),
/*
* Read more about possible values at https://www.rabbitmq.com/tutorials/amqp-concepts.html
*/
'passive' => env('RABBITMQ_QUEUE_PASSIVE', false),
'durable' => env('RABBITMQ_QUEUE_DURABLE', true),
'exclusive' => env('RABBITMQ_QUEUE_EXCLUSIVE', false),
'auto_delete' => env('RABBITMQ_QUEUE_AUTODELETE', false),
'arguments' => env('RABBITMQ_QUEUE_ARGUMENTS'),
],
],
/*
* Determine the number of seconds to sleep if there's an error communicating with rabbitmq
* If set to false, it'll throw an exception rather than doing the sleep for X seconds.
*/
'sleep_on_error' => env('RABBITMQ_ERROR_SLEEP', 5),
/*
* Optional SSL params if an SSL connection is used
* Using an SSL connection will also require to configure your RabbitMQ to enable SSL. More details can be founds here: https://www.rabbitmq.com/ssl.html
*/
'ssl_params' => [
'ssl_on' => env('RABBITMQ_SSL', false),
'cafile' => env('RABBITMQ_SSL_CAFILE', null),
'local_cert' => env('RABBITMQ_SSL_LOCALCERT', null),
'local_key' => env('RABBITMQ_SSL_LOCALKEY', null),
'verify_peer' => env('RABBITMQ_SSL_VERIFY_PEER', true),
'passphrase' => env('RABBITMQ_SSL_PASSPHRASE', null),
],
],
4、修改 .env 文件
QUEUE_CONNECTION=rabbitmq #这个配置env一般会有先找到修改为这个
#以下是新增配置
RABBITMQ_HOST=rabbitmq #mq的服务器地址，我这里用的是laradock，具体的就具体修改咯RABBITMQ_PORT=5672 #mq的端口RABBITMQ_VHOST=/RABBITMQ_LOGIN=guest #mq的登录名RABBITMQ_PASSWORD=guest #mq的密码RABBITMQ_QUEUE=queue_name #mq的队列名称
5、创建任务类php artisan make:job Queue执行之后会生成一个文件app/Jobs/Queue.php
例子：
namespace App\Jobs;
use App\Entities\Posts;use Illuminate\Bus\Queueable;use Illuminate\Foundation\Bus\Dispatchable;use Illuminate\Queue\SerializesModels;use Illuminate\Queue\InteractsWithQueue;use Illuminate\Contracts\Queue\ShouldQueue;
class Queue implements ShouldQueue{
use Dispatchable, InteractsWithQueue, Queueable, SerializesModels;
private $data;
/**
* Queue constructor.
* @param $data
*/
public function __construct($data)
{
$this->data = $data;
}
/**
* Execute the job.
*
* @return void
*/
public function handle()
{
try{
$insert = [
'title'=>$this->data->title,
'author_id'=>$this->data->author_id,
'content'=>$this->data->content,
'description'=>$this->data->description,
];
$result = Posts::create($insert);
echo json_encode(['code' => 200, 'msg' => $result]);
}catch (\Exception $exception) {
echo json_encode(['code'=>0,'msg'=>$exception->getMessage()]);
}
}}
6、生产，把数据放进mq队列
namespace App\Http\Controllers;
use App\Entities\CostaNews;use App\Jobs\Queue;
class IndexController extends Controller{
public function index()
{
$data = CostaNews::get();
foreach ($data as $item) {
$this->dispatch(new Queue($item));
}
return response()->json(['code'=>0, 'msg'=>"success"]);
}
}
7、消费队列执行命令进行消费：php artisan queue:work rabbitmq效果如下：
root@9e99cf9fba73:/var/www/blog# php artisan queue:work rabbitmq[2018-12-24 07:34:32][5c208bf66e63b3.56379160] Processing: App\Jobs\Queue{"code":200,"msg":{"title":1,"author_id":2,"content":"\u5185\u5bb9","description":"\u63cf\u8ff0","updated_at":"2018-12-24 07:34:32","created_at":"2018-12-24 07:34:32","id":1}}[2018-12-24 07:34:32][5c208bf66e63b3.56379160] Processed: App\Jobs\Queue[2018-12-24 07:34:32][5c208bf66ff7c3.20969590] Processing: App\Jobs\Queue{"code":200,"msg":{"title":2,"author_id":2,"content":"\u5185\u5bb92","description":"\u63cf\u8ff02","updated_at":"2018-12-24 07:34:32","created_at":"2018-12-24 07:34:32","id":2}}[2018-12-24 07:34:32][5c208bf66ff7c3.20969590] Processed: App\Jobs\Queue[2018-12-24 07:34:32][5c208bf6702695.93123122] Processing: App\Jobs\Queue{"code":200,"msg":{"title":3,"author_id":2,"content":"\u5185\u5bb93","description":"\u63cf\u8ff03","updated_at":"2018-12-24 07:34:32","created_at":"2018-12-24 07:34:32","id":3}}[2018-12-24 07:34:32][5c208bf6702695.93123122] Processed: App\Jobs\Queue[2018-12-24 07:34:32][5c208bf6706e24.78015170] Processing: App\Jobs\Queue{"code":200,"msg":{"title":4,"author_id":2,"content":"\u5185\u5bb94","description":"\u63cf\u8ff04","updated_at":"2018-12-24 07:34:32","created_at":"2018-12-24 07:34:32","id":4}}[2018-12-24 07:34:32][5c208bf6706e24.78015170] Processed: App\Jobs\Queue[2018-12-24 07:34:32][5c208bf6709be0.07998731] Processing: App\Jobs\Queue{"code":200,"msg":{"title":5,"author_id":2,"content":"\u5185\u5bb95","description":"\u63cf\u8ff05","updated_at":"2018-12-24 07:34:32","created_at":"2018-12-24 07:34:32","id":5}}[2018-12-24 07:34:32][5c208bf6709be0.07998731] Processed: App\Jobs\Queue
五．以上这些测试好后，才可进行下一步配置，就是pm2的配置，使用以下命令：
pm2 start 你的项目路径/artisan --name laravel-worker --interpreter php -- queue:work --daemon
结尾：
以上这些配置好后，你就大功告成了，就可以用pm2监控队列了，当然，配置过程中也有可能遇到困难，欢迎留言，我也会找个时间来解答！
