如何修复“Illuminate\Database\QueryException: SQLSTATE[HY000] [1044] 用户拒绝访问”

Question

我试着跑： php artisan migrate

还可以在 Windows 上使用 Xampp 连接到 MySQL。

我收到这个错误：

Illuminate\Database\QueryException  : SQLSTATE[HY000] [1044] Access
denied for user ''@'localhost' to database 'homestead' (SQL: select *
from information_schema.tables where table_schema = homestead and
table_name = migrations)

  Please use the argument -v to see more details.

.env 文件：

DB_CONNECTION=mysql 
DB_HOST=127.0.0.1 
DB_PORT=3306 
DB_DATABASE=homestead 
DB_USERNAME=homestead 
DB_PASSWORD=

Answer 1

打开.env文件并进行编辑。只需设置正确的数据库凭据：

DB_CONNECTION=mysql 
DB_HOST=127.0.0.1 
DB_PORT=3306 
DB_DATABASE=            // Your Database Name
DB_USERNAME=           // Yout Database Username
DB_PASSWORD=          // Your Database Password 

该DB_USERNAME应设置为root，如果你没有一个默认的用户名在MySQL安装的XAMPP。

如果数据库没有设置密码，清除它DB_PASSWORD，空格也必须删除（以前我也遇到过这个问题，window把空格当作密码）

.env编辑完成后，请在终端中输入此命令以清除缓存：

php artisan config:cache
