<h3 id="d-abord-l-export">D'abord l'export:</h3>
|
|
<p>L'outil s'appelle mysqldump il est installé avec mariadb-server.</p>
|
|
<p>Donc on peut d'abord lister les base données pour être sûr de celle
|
|
que l'on veut exporter ? </p>

<p>Si par exemple on veut exporter la base nextcloud on tapera ceci
|

dans notre shell:</p>

<pre style="background-color:#272822;">
|

<span style="color:#f8f8f2;">$ mysqldump</span><span style="font-style:italic;color:#fd971f;"> -u</span><span style="color:#f8f8f2;"> root</span><span style="font-style:italic;color:#fd971f;"> -p</span><span style="color:#f8f8f2;"> nextcloud </span><span style="color:#f92672;">></span><span style="color:#f8f8f2;"> nextcloud_export.sql
|
|
</span></pre><h3 id="importer-sa-base-de-donnees">Importer sa base de données</h3>
|
|
<p>Pour importer notre fichier on va devoir créer la base et l'utilisateur qui aura
|

les droits sur la base. </p>

|
|
<p>Si tout se passe bien normalement à la fin de chaque commande mysql
|
|
vous verrez un message Query OK ... , c'est que c'est bon :).</p>
|
|
<p>Maintenant on va pouvoir importer notre fichiers comme ceci : </p>

<pre style="background-color:#272822;">

<span style="color:#f8f8f2;">$ mysql</span><span style="font-style:italic;color:#fd971f;"> -u</span><span style="color:#f8f8f2;"> nextbase</span><span style="font-style:italic;color:#fd971f;"> -p</span><span style="color:#f8f8f2;"> nextcloud </span><span style="color:#f92672;"><</span><span style="color:#f8f8f2;"> nextcloud_export.sql

<p>Si vous n'avez aucun message d'erreur, c'est fini ! </p>
