遺留的MySQL設定警告：mysql_connect()：檔案或目錄不存在
親愛的開發者們， 我已經解決了最初的問題，但如果有人有一個可以運行這個的docker映像，我會非常感激。 我需要幫助一個非常舊的應用程式。
我正在為一個舊應用程式設定一個虛擬機器環境。如果你打算幫助，請仔細閱讀。
我有一個即將被丟棄的舊應用程序，因為我們正在進行重寫，但是舊應用程式仍然需要支持，並且它運行著非常舊版本的PHP和MYSQL。下面的程式碼應該可以測試資料庫連線是否正常。
require_once("/var/www/html/class/autoload.php");
$database = $_ENV['DB_HOST'];
$DBuser = $_ENV["MYSQL_USER"];
$DBpass = $_ENV["MYSQL_USER"];
$link = mysql_connect($database, $DBuser, $DBpass, null);
if (!$link) {
echo "Error: Unable to connect to MySQL." . PHP_EOL;
echo "Debugging errno: " . mysql_error() . PHP_EOL;
exit;
}
程式碼出錯，給我以下錯誤訊息：
Warning: mysql_connect(): No such file or directory in /var/www/html/docker_build/test_db.php on line 10 Error: Unable to connect to MySQL. Debugging errno: No such file or directory
如果在同一個程式碼區塊中使用mysqli_connect，一切都正常，但是該專案使用的是mysql_functions。該應用程式在暫存和生產伺服器上運行正常，我嘗試將設定複製到我的虛擬機器上，這是以前工作的dockerfile，但最近一些安全性更新導致它無法運作。

我只需要讓它運行起來。如果可以使用docker完成，那就太完美了，但我認為該映像已經過時了。非常感謝任何幫助。我可以為你提供env和.ini的設定。我不想在問題中貼上太多內容。
我嘗試了一切，查看了.ini和.env以及所有的Linux設定。看起來mysql套接字沒有正確設置，然而命令列連接mysql -uroot -p是正常的。
