我在 EC2 大型实例上有一个 magento 网站，数据库在 RDS 上，这又是一个大型实例。现在，1. 我在网站上最多有 25 人的流量。2.我及时遇到以下sql错误，有时会在6-7小时后出现，有时会在一天后出现，有人可以帮我解决这个问题吗？3.为了摆脱这个错误，我重新启动服务并恢复正常，但过了一段时间又再次弹出这个错误！

处理您的请求时出错 SQLSTATE[HY000] [2002] 连接超时

这是一些数据库连接错误。检查本地、xml 文件以获取数据库连接设置。您的数据库是否在同一台服务器上，否则使用套接字

我在 RDS 实例上遇到了同样的问题。通过同一服务器上的单独文件检查连接性。

$link = mysqli_connect("host", "username", "password", "database");

if (!$link) {
    echo "Error: Unable to connect to MySQL." . PHP_EOL;
    echo "Debugging errno: " . mysqli_connect_errno() . PHP_EOL;
    echo "Debugging error: " . mysqli_connect_error() . PHP_EOL;
    exit;
}

echo "Success: A proper connection to MySQL was made! The my_db database is great." . PHP_EOL;
echo "Host information: " . mysqli_get_host_info($link) . PHP_EOL;

mysqli_close($link);
