MySQL via SSH Tunnel Access Denied - mysql

Question

I want to use SSH tunnel to connect to MySQL DB on remote host.
I've set up the tunnel with command:
ssh user#host -L 3307:remote_mysql_hostname:3306
I can successfull connect with HeidiSQL using this settings:
hostname: localhost
user: remote_mysql_user_login
password: remote_mysql_user_password
port: 3307
But when i use PDO in PHP to connect, i get:
Access denied for user 'remote_mysql_user_login'#'localhost' (using password: YES)
My PDO Dns is sth like this:
mysql:type=Core_Db_Adapter_Pdo_Mysql;host=localhost;port=3307;dbname=db_name;
Where is the trick?
Solution:
#symcbean thanks!
The problem was (as suggested by #symcbean) in hostname.
Changing to '127.0.0.1' fix the problem.**

I borrowed from your example and was able to connect to a remote host using your same SSH tunnel setup. Can you share the PHP script you are using to get some more info about your setup?
You may try a hostname other than 'localhost' for your remote database you are connecting to.
setup ssh tunnel - I setup an entry in /etc/hosts for my_db_host_name instead of using localhost
ssh my_user#my_remote_host -L 3307:my_db_host_name:3306
<?php
$dsn = 'mysql:host=my_db_host_name;dbname=my_db;port=3307';
$username = 'my_user';
$password = 'my_pass';
$options = array(
PDO::MYSQL_ATTR_INIT_COMMAND => 'SET NAMES utf8',
);
$dbh = new PDO($dsn, $username, $password, $options);
$result = $dbh->query("select * from my_table");
try {
foreach($result as $row) {
echo "column1: " . $row['column1'];
}
} catch (PDOException $pde) {
echo "PDO exception: $pde";
}
echo "done \n";
?>
