It's just a matter of permissions. Change the folder permission to 744.
chmod -R 744 /path/to/folder
You might need to find phpmyadmin.conf to change
<Directory "/path/to/phpmyadmin">
Options Indexes FollowSymLinks MultiViews
AllowOverride all
Order Deny,Allow
Allow from all
</Directory>
to this:
<Directory "/path/to/phpmyadmin">
Options Indexes FollowSymLinks MultiViews
AllowOverride all
Order Deny,Allow
Deny from all
Allow from 127.0.0.1
</Directory>
Restart apache to apply changes.
Side note: Never use root as an owner for web pages, specially dynamic ones.
You might as well set your password to welcome123
