Php 致命錯誤：未捕獲的 PDOException：SQLSTATE[HY000] [1045] 用戶 'fobos'@'localhost' 訪問被拒絕（使用密碼：YES）

Question

我在連接到 Mysql 數據庫（v5 和 v8）時遇到問題。 如果用戶是 root 則可以，但是如果我創建用戶 'fobos' 我有連接錯誤 1045（錯誤消息PDOException: SQLSTATE[HY000] [1045] Access denied for user 'fobos'@'localhost' (using password: YES) in vms\\public\\staff\\visitors\\vms.php on line 14 ）。 我不知道為什么會這樣。

Mysql -> 創建用戶 fobos

SELECT user, host FROM mysql.user

+------------------+-----------+
| user             | host      |
+------------------+-----------+
| debian-sys-maint | localhost |
| fobos            | localhost |
| mysql.infoschema | localhost |
| mysql.session    | localhost |
| mysql.sys        | localhost |
| root             | localhost |
+------------------+-----------+

 CREATE USER 'fobos'@'localhost' IDENTIFIED BY '$zP_jaGA5xAE@"8~7TpdM';
    
 GRANT ALL PRIVILEGES ON visitor_managment_system.*
        TO 'fobos'@'localhost'
        IDENTIFIED BY '$zP_jaGA5xAE@"8~7TpdM';

php

   public function __construct() {
    
        $this->connect = new PDO("mysql:host = localhost; dbname = visitor_managment_system","fobos", '$zP_jaGA5xAE@\"8~7TpdM');
    }

Answer 1

在 mysql cli 中嘗試 FLUSH PRIVILEGES 命令
