在Yii中创建cronjob定时任务的实例详解

本文实例讲述了Yii框架创建cronjob定时任务的方法。分享给大家供大家参考，具体如下：

1. 添加环境配置

protected/config/console.php

<?php
require_once('env.php');
// This is the configuration for yiic console application.
// Any writable CConsoleApplication properties can be configured here.
return array(
  'basePath'=>dirname(__FILE__).DIRECTORY_SEPARATOR.'..',
  'name'=>'CMS Console',
  // application components
  'components'=>array(
    //Main DB connection
    'db'=>array(
      'connectionString'=>DB_CONNECTION,
      'username'=>DB_USER,
      'password'=>DB_PWD,
      'enableParamLogging'=>true,
    ),
    'log'=>array(
      'class'=>'CLogRouter',
      'routes'=>array(
        array(
          'class'=>'CFileLogRoute',
          'levels'=>'error, warning',
        ),
      ),
    ),
  ),
);

2. 添加定时任务执行模块

protected/commands/crons.php

<?php
defined('YII_DEBUG') or define('YII_DEBUG',true);
// including Yii
require_once('/../framework/yii.php');
// we'll use a separate config file
$configFile='/config/console.php';
// creating and running console application
Yii::createConsoleApplication($configFile)->run();

3. 添加具体的定时任务

定时任务通常是一个命令行程序,从CConsoleCommand类派生,比如
protected/commands/TestCommand.php

class TestCommand extends CConsoleCommand
{
  public function run($args) {
    //todo
  }
}

4. 创建cronjob

30 0 * * * www php /path/to/crons.php Test >>/path/to/logs/test.log

5. 传入参数给定时任务中的run($params)

30 0 * * * www php /path/to/crons.php Test param1 param2 ...
