How to use Supervisor to manage ThinkPHP6 queue?

With the continuous development of web applications, we need to handle a large number of tasks to maintain the stability and availability of the application. Using a queuing system is one solution. ThinkPHP6 provides a built-in queue system to manage tasks. However, handling a large number of tasks requires better queue management, which can be achieved using Supervisor.

This article will introduce how to use Supervisor to manage ThinkPHP6 queues. Before that, we need to understand some basic concepts:

1. Queue system
   The queue system is a way of processing tasks asynchronously, adding tasks to the queue instead of processing them directly. Once a task is added to the queue, it can be assigned to different workers to avoid long-term blocking of the web application. The queue system can also complete some complex operations of tasks.
2. Task
   In a queue system, a task is the work that needs to be performed. You can package the code that needs to be executed asynchronously into a task, and then add the task to the queue to wait for subsequent processing. We can use the queue component in the PHP framework or a third-party library to manage tasks, such as Laravel's queue component or Beanstalkd, etc.
3. Supervisor
   Supervisor is a process control system that can monitor and control one or more processes, including queue workers. Supervisor can make the queue system more stable and durable. Using Supervisor can automatically restart workers when tasks fail, and can also ensure that queue tasks can continue to be processed after the web application is restarted.

After understanding these basic concepts, we will introduce how to use Supervisor to manage ThinkPHP6 queues.

Step 1: Install Supervisor

To use Supervisor for queue management, we first need to install Supervisor. On the Ubuntu system, you can use the following command to install:

sudo apt-get install supervisor

On the CentOS system, you can use the following command to install:

sudo yum install supervisor

After the installation is complete, you can use the following command to start Supervisor:

sudo systemctl start supervisor

At the same time, we also need to create a new configuration file in the configuration file/etc/supervisor/conf.d/to manage queue workers. We can create a file with any name in this directory, such aslaravel-worker.conf. Next, we'll cover how to edit this file.

Step 2: Edit the Supervisor configuration file

Edit the Supervisor configuration file and add workers to the Supervisor monitoring list. We can use the following command to edit the configuration file we just created:

sudo nano /etc/supervisor/conf.d/laravel-worker.conf

Add the following configuration to the file:

[program:laravel-worker] process_name=%(program_name)s_%(process_num)02d directory=/var/www/laravel #修改为你的项目目录 command=php /var/www/laravel/artisan queue:work autostart=true autorestart=true user=www-data #修改为你的Web服务器运行用户 numprocs=8 #工作者数量，此处建议设置为CPU核心数2-4倍 redirect_stderr=true stdout_logfile=/var/www/laravel/storage/logs/worker.log #修改为你的日志文件位置

After adding the above configuration to the file, we can use the following command to Reload the Supervisor configuration file:

sudo supervisorctl reread sudo supervisorctl update

So that the Supervisor can start our queue workers and manage them. We can use the following command to view all processes started by Supervisor:

sudo supervisorctl status

Step 3: Test the queue task

Now, we have successfully started the queue worker using Supervisor. Next, we need to test the queue task. First, make sure your queue is configured in your application.

Add a test task somewhere and let the queue start working. For example, create an E-mails sending task:

user = $user; } public function fire(Job $job, $data) { //发送Email的代码 if (Math.random() < 0.5) { // 处理失败 $job->release(5);// 5秒后重试 } else { // 成功处理 $job->delete(); } } }

Add a method in the controller and add the task:

 'test@test.com', 'name' => 'test']; $job = new ppqueueSendEmail($user); app('queue')->push($job); } }

In this way, we can successfully use Supervisor to manage the ThinkPHP6 queue. If you want to know more about the queue system, you can read the official documentation. I hope this article can help you successfully run your web application!
