\common\config\main.php或者\backend\config\main.php中加

‘authManager‘ => [
            ‘class‘ => ‘yii\rbac\DbManager‘,
            ‘itemTable‘ => ‘auth_item‘,
            ‘assignmentTable‘ => ‘auth_assignment‘,
            ‘itemChildTable‘ => ‘auth_item_child‘,
        ],

yii中自帶的四張表：

vendor/yiisoft/yii2/rbac/migrations/schma-mysql.sql 復制裏面的內容在mysql中運行

還要自己加一個user表：

DROP TABLE IF EXISTS `user`;
CREATE TABLE `user` (
  `id` int(11) NOT NULL AUTO_INCREMENT,
  `username` varchar(255) NOT NULL,
  `auth_key` varchar(32) NOT NULL,
  `password_hash` varchar(255) NOT NULL,
  `password_reset_token` varchar(255) DEFAULT NULL,
  `email` varchar(255) NOT NULL
 
,
  `role` smallint(6) NOT NULL DEFAULT ‘10‘,
  `status` smallint(6) NOT NULL DEFAULT ‘10‘,
  `created_at` int(11) NOT NULL,
  `updated_at` int(11) NOT NULL,
  PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=3 DEFAULT CHARSET=utf8;
