Yii: 创建cronjob定时任务

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 ...
