====== Installer NextCloud ======
 
[[https://nextcloud.com/fr/|NextCloud]] est une plateforme de stockage et partage de données .
</jumbotron>

===== Jail =====

Préparez une [[jails:zfs|jail]], nommée ''next''.
C'est une application //php//,  suivez la documentation [[ports:web:php|à ce sujet]].
Elle repose sur une base de données [[ports:db:mariadb|mysql/mariadb]].

===== Installation =====

Installez votre environnement //php//:

<code bash>
# pkg -j nextcloud install www/nextcloud databases/pecl-memcache 
</code>

vous pouvez aussi ajouter ''graphics/pecl-imagick'' pour éviter un avertissement sur la génération du favicon, mais il embarque beaucoup de dépendances.\\
Construisez avec vos [[jails:zfs#ports|poudrieres]] la version ''nox11'':
<file make nextcloud-list>
DEFAULT_VERSIONS+= imagemagick=6-nox11
</file>

===== Base de donnée =====

Créer un utilisateur dédié à //nextcloud//, dédié à la base que l'on va créer:
<code sql>
CREATE USER 'nextcloud'@'192.168.0.x' IDENTIFIED BY 'motdepasse';
GRANT ALL PRIVILEGES ON nextcloud.* TO 'nextcloud'@'192.168.0.x';
FLUSH PRIVILEGES;
exit;
</code>

<callout type="warning" icon="true">
Notez que vous devez associer votre utilisateur à l'adresse de la //jail nextcloud//.
</callout>

===== Nextcloud =====

Autoriser l'utilisateur //www// à configurer le programme:
<code bash>
chown  www /usr/local/www/nextcloud/config
chown  www /usr/local/www/nextcloud/config/config.php
</code>

===== Nginx =====

Après avoir configuré votre nom de domaine et installé des clefs //https//, configurez le serveur web comme suit:

<file nginx [highlight_lines_extra="2,15,27,30,31,32,157"]>
upstream php-handler {

    # that file is correctly served; if it doesn't, then the request is passed to
    # the front-end controller. This consistent behaviour means that we don't need
    # to specify custom rules for certain paths (e.g. images and other assets,
    # `/updater`, `/ocm-provider`, `/ocs-provider`), and thus
    # `try_files $uri $uri/ /index.php$request_uri`

La variable ''MAILTO'' va vous permettre de recevoir des messages en cas de problème. Par contre, dans ce cas, vous allez recevoir toutes les cinq minutes. ;-)
Si vous voulez éviter ça, choisissez ''MAILTO=""''.
===== Configurer =====

C'est la dernière étape, il suffit de se connecter à l'adresse réglée sur //nginx// et de configurer la base de donnée en [[https://docs.nextcloud.com/server/26/admin_manual/installation/installation_wizard.html|suivant le guide]].
Ajoutez dans la configuration 
<file php /usr/local/www/nextcloud/config/config.php>
'default_phone_region' => 'FR',
</file>

Préparez //newsyslog// pour qu'il gère les fichiers journaux:

<file whitespace /etc/newsyslog.conf.d/nextcloud.conf>
