新手尝试学习如何连接到phpmyadmin

Question

I have one file on one web serve and my phpmyadmin SQL databases on a seperate server and am currently trying to connect to my external serve but it doesnt seem to work.

I keep getting the error message:

'Access denied for user ''@'localhost' (using password: NO)'

and am not sure what this means.

Any help would be greatly appreciated or even an article to get started on figuring this out since I cant seem to find anything myself.

Thank you

EDIT --- PDO SCRIPT ---

My PDO Script is the generic one from w3, I have place holders for security reasons.

<?php
    $servername = "externalIP";
    $username = "username";
    $password = "password";

try {
    $conn = new PDO("mysql:host=$servername;dbname=Reservations", $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();
    }

Answer 1

您必须找到您的phpmyadmin页面，并使用密码登录。

Answer 2

Try this one :

if you have not assign password into database for specific user then you just have to apply 'root' as user and leave blank password field and also set your hostname as 'localhost' or 127.0.0.1

also remember that you have to start first apache and mysql services before access.

Answer 3

If you are using remote server as database then not required.in that case you have to apply your remote Ip address and also remember that in that remote server if you have not specific user then leave password as blank.

one another way to debug mysql connection into your remote server creating mysql connection file with its required paramter to check that your remote server ok or not.

Answer 4

This error will come most probably because of user permission issue. Make sure you have privilege to that user for that database.
