README

这个扩展基于这个和这个构建。项目的目标是能够在单台机器上启动多个工作进程。

安装

建议您通过composer安装Gearman库（通过composer）。为此，请将以下行添加到您的composer.json文件中。

{
    "require": {
       "shakura/yii2-gearman": "dev-master"
    }
}

配置

'components' => [
  'gearman' => [
      'class' => 'shakura\yii2\gearman\GearmanComponent',
      'servers' => [
          ['host' => '127.0.0.1', 'port' => 4730],
      ],
      'user' => 'www-data',
      'jobs' => [
          'syncCalendar' => [
              'class' => 'common\jobs\SyncCalendar'
          ],
          ...
      ]
  ]
],
...
'controllerMap' => [
    'gearman' => [
        'class' => 'shakura\yii2\gearman\GearmanController',
        'gearmanComponent' => 'gearman'
    ],
    ...
],

作业示例

namespace common\jobs;

use shakura\yii2\gearman\JobBase;

class SyncCalendar extends JobBase
{
    public function execute(\GearmanJob $job = null)
    {
        // Do something
    }
}

管理工作进程

yii gearman/start 1 // start the worker with unique id
yii gearman/restart 1 // restart worker
yii gearman/stop 1 // stop worker

使用Dispatcher的示例

Yii::$app->gearman->getDispatcher()->background('syncCalendar', new JobWorkload([
    'params' => [
        'data' => 'value'
    ]
])); // run in background
Yii::$app->gearman->getDispatcher()->execute('syncCalendar', new JobWorkload([
    'params' => [
        'data' => 'value'
    ]
])); // run synchronize

用于管理多个工作进程的Supervisor配置示例

[program:yii-gearman-worker]
command=php [path_to_your_app]/yii gearman/start %(process_num)s
process_name=gearman-worker-%(process_num)s
priority=1
numprocs=5
numprocs_start=1
autorestart=true
