Serveur SQL MariarDB

Installation :

# apt install mariadb-server

On lance le script pour attribuer un mot de passe root, virer l'utilisateur anonyme etc.

# mysql_secure_installation

Set root password? [Y/n] y

Remove anonymous users? [Y/n] y

Disallow root login remotely? [Y/n] y

Remove test database and access to it? [Y/n] y

Reload privilege tables now? [Y/n] y
... Success!

On créé la base de donnée pour NextCloud :

Utiliser un mot de passe différent de root mysql.

# mysql -U

MariaDB [(none)]> create database nextcloud;
MariaDB [(none)]> create user nextcloud@localhost identified by 'motdepasse';
MariaDB [(none)]> grant all privileges on nextcloud.* to nextcloud@localhost IDENTIFIED BY 'motdepasse';
MariaDB [(none)]> flush privileges;
MariaDB [(none)]> quit;

Configuration de Nextcloud

On modifie le fichier de configuration de NextCloud pour qu'il accepte le nom de domaine et le reverse proxy :

NextCloud ~# vi /var/www/nextcloud/config/config.php

'trusted_domains' =>
 array (
         0 => '12.34.56.789',
         1 => 'nextcloud.exemple.com',
 ),
 'trusted_proxies' =>
 array (
         0 => 'IP_PROXY',
 ),
 'overwritewebroot' => '/',

NextCloud sera maintenant accessible via nextcloud.exemple.com
