laradock 里 执行 php artisan migrate 报错

 Illuminate\Database\QueryException

我的 .env 配置如下：

DB_CONNECTION=mysql
DB_HOST=mysql
DB_PORT=3306
DB_DATABASE=abcabc
DB_USERNAME=root
DB_PASSWORD=root

后续备注：我根据这个帖子：laracasts.com/discuss/channels/lar...
修改成了 0.0.0.0 , 可以正常 php artisan migrate 了，但是对项目的正常操作就会提示：
Illuminate\Database\QueryException SQLSTATE[HY000] [2002] Connection refused (SQL: select * fromadmin_userswhereid= 2 limit 1)
