原文链接

2:根目录下入口文件
a)前台
复制yii2\frontend\web\index.php到根目录
修改内容

<?php  
defined('YII_DEBUG') or define('YII_DEBUG', true);  
defined('YII_ENV') or define('YII_ENV', 'dev');  

require(__DIR__ . '/vendor/autoload.php');  
require(__DIR__ . '/vendor/yiisoft/yii2/Yii.php');  
require(__DIR__ . '/common/config/bootstrap.php');  
require(__DIR__ . '/frontend/config/bootstrap.php');  

$config = yii\helpers\ArrayHelper::merge(  
    require(__DIR__ . '/common/config/main.php'),  
    require(__DIR__ . '/common/config/main-local.php'),  
    require(__DIR__ . '/frontend/config/main.php'),  
    require(__DIR__ . '/frontend/config/main-local.php')  
);  

(new yii\web\Application($config))->run();  

b)修改yii2\frontend\config\mian.php

'assetManager'=>[  
            'basePath'=>'@webroot/frontend/web',  
            'baseUrl'=>'@web/frontend/web/assets',  
        ], 

c)如果引入其他公共css/jswenjian
修改yii2\frontend\assets\AppAsset.php或自定义文件

public $basePath = '@webroot/frontend/web/';
public $baseUrl = '@web/frontend/web/';
