php - AWS PHP PDO MySQL 连接问题 SQLSTATE[HY000] [2002]

Question

我正在尝试按照本教程连接到我的 AWS MYSQL 数据库:https://docs.aws.amazon.com/zh_cn/elasticbeanstalk/latest/dg/create_deploy_PHP.rds.html#php-rds-connect .

我的代码

<?php
$dbhost = $_SERVER['RDS_HOSTNAME'];
$dbport = $_SERVER['RDS_PORT'];
$dbname = $_SERVER['RDS_DB_NAME'];
$charset = 'utf8' ;

$dsn = "mysql:host={$dbhost};port={$dbport};dbname={$dbname};charset={$charset}";
$username = $_SERVER['RDS_USERNAME'];
$password = $_SERVER['RDS_PASSWORD'];

$pdo = new PDO($dsn, $username, $password);
?>

输出

SQLSTATE[HY000] [2002] No connection could be made because the target machine actively refused it.

我能够使用 MySQL Workbench 连接到我的数据库。

任何帮助将不胜感激!

请验证您的数据库设置。可能是端口设置错误。如果您使用localhost，可以尝试将主机更改为127.0.0.1。 MySQL 进程可能会卡住。
