无法使用phpMyAdmin访问mysql服务器

我最近安装了最新版本的WAMP，但在访问MySQL（MariaDB）服务器时遇到问题。我可以通过MariaDB控制台访问服务器。因此，我确信密码和用户名是正确的，并且服务器正在运行

WAMP: 3.2.2
Apache: 2.4.41
PHP: 7.4.0
MariaDB: 10.4.10
phpMyAdmin: 5.0.2

当我使用phpMyAdmin网页访问时：

我还尝试使用一个简单的测试脚本访问：

<?php
$servername = "localhost";
$username = "root";
$password = "";

try {
  $conn = new PDO("mysql:host=$servername;dbname=myDB", $username, $password);
  // set the PDO error mode to exception
  $conn->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
  echo "Connected successfully";
} catch(PDOException $e) {
  echo "Connection failed: " . $e->getMessage();
}
?>

密码已更改，我已更新测试脚本

$password=“MyNewPass”，仍然是相同的结果

WAMP，右键单击，工具->测试端口3306。也给出了预期的结果：

***** Test which uses port 3306 *****

===== Tested by command netstat filtered on port 3306 =====


Test for TCP
Your port 3306 is used by a processus with PID = 8660
The processus of PID 8660 is 'mysqld.exe' Session: Services
The service of PID 8660 for 'mysqld.exe' is 'wampmariadb64'
This service is from Wampserver - It is correct

Test for TCPv6
Your port 3306 is used by a processus with PID = 8660
The processus of PID 8660 is 'mysqld.exe' Session: Services
The service of PID 8660 for 'mysqld.exe' is 'wampmariadb64'
This service is from Wampserver - It is correct

任何帮助都将不胜感激。
似乎您应该从wamp工具配置phpMyAdmin，并且您应该从本地ip地址使用
ipconfig
控制台输入php脚本，而不是使用php脚本。
这可能是某种保护，比如SELinux阻止您的Apache访问数据库吗？编辑：似乎您在Windows上尝试将地址更改为
127.0.0.1/testConnection.php
？有时我会遇到
localhost
被解析为ipv6格式
：：1
，然后pma无法解释它并导致错误。我尝试过，得到了相同的错误我尝试更改为本地ip地址，得到了相同的结果。由于某些原因，apache无法连接到mysql服务器
