Install mutillidae and DVWA on the same machine?

Well I solved it, at first I had mutillidae installed which used myslq, then I installed dvwa which uses mariadb, so I don't know if I'm fine but when installing mariadb(versions 10.6 or higher) it dumps the mysql database, so it got misconfigured or something like that, so I did the following:

If you have a password in mysql, put this (in my case it was 'mutillidae'):

mysql -u root -p{ your root password here}

Otherwise just with it:

sudo mysql;

and the following is this:

USE mysql;
ALTER USER 'root'@'localhost' IDENTIFIED VIA mysql_native_password;
FLUSH PRIVILEGES;
exit

At least that's what I did, but before I didn't have a database called 'mutillidae', only the one of 'dvwa', so I created a database with the name of mutillidae.

In my 'database-config.inc' file located in the path /var/www/html/mutillidae/includes, I have the following:

<?php
define('DB_HOST', '127.0.0.1');
define('DB_USERNAME', 'root');
define('DB_PASSWORD', '');
define('DB_NAME', 'mutillidae');
define('DB_PORT', 3306);
?>

In my DVWA 'config.inc.php' file located at the path /var/www/html/DVWA/config, I have the following:

$_DVWA = array();
$_DVWA[ 'db_server' ]   = '127.0.0.1';
$_DVWA[ 'db_database' ] = 'dvwa';
$_DVWA[ 'db_user' ]     = 'dvwa';
$_DVWA[ 'db_password' ] = 'p@ssw0rd';
$_DVWA[ 'db_port'] = '3306';
