假设Yii项目路径为 /home/apps/

1. 创建文件 /home/apps/protected/commands/crons.php

复制代码 代码如下:
<?php

$yii = "/home/apps/framework/yii.php";

require_once($yii); 

$configFile = dirname(__FILE__)."/../config/console.php";

Yii::createConsoleApplication($configFile)->run();

2. 创建需要的配置文件 /home/apps/protected/config/console.php，配置需要的组件、数据库连接，日志等信息，格式类似主配置文件main.php

复制代码 代码如下:
<?php 
return array(
    "basePath"=>dirname(__FILE__).DIRECTORY_SEPARATOR."..",

    "name"=>"Emergency",

    "import"=>array( 
            "application.models.*",
            "application.components.*",
            "application.extensions.*",
    ),

    "components"=>array(
        "log"=>array(
            "class"=>"CLogRouter",
            "routes"=>array(
                array(
                    "class"=>"CFileLogRoute",
                    "levels"=>"info, warning, error",
                ),
            ),
        ),
        "db"=>array(
            "class"=>"application.extensions.PHPPDO.CPdoDbConnection",
            "pdoClass" => "PHPPDO",
            "connectionString" => "mysql:host=xxxx;dbname=xxx",
            "emulatePrepare" => true,
            "username" => "xxx",
            "password" => "xxx",
            "charset" => "utf8",
            "tablePrefix" => "tbl_",
        ),
    ), 

    "params" => require("params.php"),
);

3. 在 /home/apps/protected/commands/ 下新建 TestCommand 类，继承 CConsoleCommand，在TestCommand中，可以使用项目的配置信息和Yii的各种方法

复制代码 代码如下:
<?php 
class TestCommand  extends CConsoleCommand 
{ 
    public function run()
    { 
        ...
    } 
}

4. 创建定时任务

复制代码 代码如下:
$ crontab -e

插入

复制代码 代码如下:
1 * * * * /home/php/bin/php -f /home/apps/protected/commands/crons.php Test &

即为每小时的第一分钟执行TestCommand类中的内容，类似的可以在/home/apps/protected/commands/下新建其他类，使用命令行执行。
