同一域名下前后台用户分离登录 [ 2.0 版本 ]

后台配置:
将backen/web/index.php复制到根目录重命名admin.php(可以根据需要命名)
然后将里面配置路径修改如下:

defined('YII_DEBUG') or define('YII_DEBUG', false);
defined('YII_ENV') or define('YII_ENV', 'prod');

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


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

$application = new yii\web\Application($config);
$application->language='zh-CN';
$application->run();

找到config文件夹在main-local.php
在$config里面修改成如下:

$config = [
    'components' => [
        'request' => [
            // !!! insert a secret key in the following (if it is empty) - this is required by cookie validation
            'cookieValidationKey' => 'XXXXXXXXXX',
        ],
        'session' => [
            'name' => 'PHPBACKSESSID',//可以自定义
            'savePath' => __DIR__ . '/../tmp',//手工在backend目录下新建文件夹TMP
        ],
    ],
];

前台和后台配置方法一样
