I changed the phpmyadmin mysql port number, and now I can't log in

Question

I have a mysql server running locally on port 3307, which I can connect to just fine through command line

mysql -P 3307 -h 127.0.0.1 -u root -p

In order to access this database through phpmyadmin, I changed these settings in /etc/phpMyAdmin/config.inc.php

$cfg['Servers'][$i]['host'] = '127.0.0.1';
$cfg['Servers'][$i]['port'] = '3307'; 

However when I try to log in, i get an error saying "cannot log in to the mysql server". Is this maybe an issue with apache blocking the login?

I have tried to connect using both localhost/phpMyAdmin and 127.0.0.1/phpMyAdmin.

Below is my config.inc.php file

Answer 1

Goto xampp>phpMyAdmin Directory.

Find the config.inc.php file.

Now change this line:

$cfg['Servers'][$i]['host'] = '127.0.0.1';

To

$cfg['Servers'][$i]['host'] = '127.0.0.1:3307';

OR

open my.ini file located in the XAMPP/mysql/bin/ directory, find words that contain number 3306, eq: port = 3306, then replace it with your own, such as 3307.

Answer 2

The username/password that lets you login through command prompt will let you login through phpmyadmin.

They need to be written in config.inc.php file:

<?php
/**
 * phpMyAdmin configuration file, you can use it as base for the manual
 * configuration. For easier setup you can use "setup/".
 *
 * All directives are explained in Documentation.html and on phpMyAdmin
 * wiki <http://wiki.phpmyadmin.net>.

After this modification, you need to restart your web and mysql servers.

If this still doesn't work, you can create one more user and ensure you have in config.inc.php file the following two lines:

$cfg['Servers'][$i]['user'] = 'testUser'; //mysql username here
$cfg['Servers'][$i]['password'] = 'testPassword'; //mysql password here
