===== Configuration =====
En parallèle, il faut que le serveur accepte les connections venant du réseau local.
<code bash file=/etc/mysql/mariadb.conf.d/99-local.cnf>
[mysqld]
# Instead of skip-networking the default is now to listen only on
# localhost which is more compatible and is not less secure.
bind-address            = 10.1.40.1
