此方法参考官方网站的cookbook,详细请看http://www.yiiframework.com/doc/cookbook/33/,
我在此基础上做了一些改动,人个感觉非常棒了,大家可以试一下!

首先我把目录结构写下来:

wwwroot/

    index.php

    admin.php

    assets/

    images/

    protected/

        config/

            main.php

        components/

        controllers/

        models/

        views/

        runtime/

        admin/

            config/

                main.php

            components/

            controllers/

            views/

            runtime/

前后台引导文件分别如下:

// index.php:

require(‘path/to/yii.php‘);

Yii::app()->createWebApplication(‘protected/config/main.php‘)->run();

// admin.php:

require(‘path/to/yii.php‘);

Yii::app()->createWebApplication(‘protected/admin/config/main.php‘)->run();

cookbook上的方法是前后台各有一个配置文件,这样配置比较麻烦一些,我们可以采用覆盖的方法,这是参考一个回复者的方法,我又做了一些修改.

protected/admin/config/main.php的代码如下:

$backend=dirname(dirname(__FILE__));

$frontend=dirname($backend);

Yii::setPathOfAlias(‘backend‘, $backend);

$frontendArray=require($frontend.‘/config/main.php‘);

$backendArray=array(

    ‘name‘=>‘网站后台管理系统‘,

    ‘basePath‘ => $frontend,

    ‘controllerPath‘ => $backend.‘/controllers‘,

    ‘viewPath‘ => $backend.‘/views‘,

    ‘runtimePath‘ => $backend.‘/runtime‘,

    // autoloading model and component classes

    ‘import‘=>array(

        ‘application.models.*‘,

        ‘application.components.*‘,

        ‘application.extensions.*‘,

        ‘application.extensions.nestedset.*‘,

        ‘backend.models.*‘,

        ‘backend.components.*‘, //这里的先后顺序一定要搞清

    ),

    ‘components‘=>array(

                ‘user‘=>array(

                        // enable cookie-based authentication

                        ‘allowAutoLogin‘=>true,

                ),

    ),

    // main is the default layout

    //‘layout‘=>‘main‘,

    // alternate layoutPath

    ‘layoutPath‘=>dirname(dirname(__FILE__)).DIRECTORY_SEPARATOR.‘views‘.DIRECTORY_SEPARATOR.‘layouts‘.DIRECTORY_SEPARATOR,

);

if(!function_exists(‘w3_array_union_recursive‘))

{

    /**

     * This function does similar work to $array1+$array2,

     * except that this union is applied recursively.

     * @param array $array1 - more important array

     * @param array $array2 - values of this array get overwritten

     * @return array

     */

    function w3_array_union_recursive($array1,$array2)

    {

        $retval=$array1+$array2;

        foreach($array1 as $key=>$value)

        {

            if(is_array($array1[$key]) && is_array($array2[$key]))

                $retval[$key]=w3_array_union_recursive($array1[$key],$array2[$key]);

        }

        return $retval;

    }

}

return w3_array_union_recursive($backendArray,$frontendArray);

这里我们的model是公用的,controller和view是分开的,我们还可以通过命令行对后台进行model和crud,方法如下:

>yiic shell path/to/site/admin.php
> model Article
> crud Article

这样后台对应的controller和view就生成了!
如果只对后台的变量进行配置的话,只需要修改protected/admin下的配置文件就可以了!
