這是一些數據庫連接錯誤。檢查本地xml文件的數據庫連接設置。您的數據庫是在同一臺服務器上，否則使用套接字

不，它在RDS上託管！自從我將數據庫從服務器移動到RDS後，我一直面臨着這個問題！ – user2304710 2013-04-24 05:28:03

我在RDS實例上遇到同樣的問題。通過同一臺服務器上的單獨文件檢查連接。

$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);
