phpmyadmin multiple mysql servers in one machine (Ubuntu VPS)

as The title said, I wanna access the production server and the development databases servers with one phpmyadmin, I add the production server configuration data on config.inc.php, but it seems it's not working, I production server is actually working ( sudo mysql -h 127.0.0.1 -P 3315 -u root -p ......) Here is the production server configuration inside config.inc.php file : /*

• Second server */ $i++; $cfg['Servers'][$i]['verbose'] = 'Server Name';

  $cfg['Servers'][$i]['host'] = 'localhost:3315';

  $cfg['Servers'][$i]['port'] = '3315';

  $cfg['Servers'][$i]['socket'] = '';

  $cfg['Servers'][$i]['connect_type'] = 'tcp';

  $cfg['Servers'][$i]['extension'] = 'mysql';

  $cfg['Servers'][$i]['auth_type'] = 'config';

  $cfg['Servers'][$i]['user'] = 'root';

  $cfg['Servers'][$i]['password'] = 'password';

  $i++;
