phpMyAdmin: Cannot log in to the MySQL Server

Logging phpMyAdmin, got "Cannot log in to the MySQL Server".

It was because of MySQL relocated.

So, needed:
Edit /etc/php.ini

pdo_mysql.default_socket= /var/data/mysql.sock

mysql.default_socket = /var/data/mysqld.sock

mysqli.default_socket= /var/data/mysql.sock

Edit /etc/phpMyAdmin/config.inc.php

$cfg['Servers'][$i]['socket'] = '/var/data/mysql.sock';

Update
