Présentation d'installation d'un serveur NextCloud sur debian 10.
Dans cette présentation, nous allons configurer un site https://cloud.sleto.net.
Nous utiliserons les variables DBNAME, DBUSER et DBPASSWD respectivement pour le nom, l'utilisateur et le mot de passe de base de données.
NextCloud sera installé dans /var/www/nextcloud et les fichiers partagés seront stockés dans /var/nc_data/
Utilise PHP 7.3 via fpm ainsi qu'un Serveur web sécurisé (Nginx / Let's Encrypt).
Nécessite également les outils :
sudo apt-get install -y mariadb-server redis-server php-redis
Vous devrez également ajouter le domaine cloud.sleto.net dans le Serveur DNS (bind9)
Nous allons créé une base de donnée MariaDB:
mariadb -h localhost -u root -e " CREATE DATABASE $DBNAME CHARACTER SET utf8mb4 COLLATE utf8mb4_general_ci; CREATE USER $DBUSER@localhost identified by '$DBPASSWD'; GRANT ALL PRIVILEGES on $DBNAME.* to $DBUSER@localhost; FLUSH privileges; "
sed -i "s/port 6379/port 0/" /etc/redis/redis.conf sed -i s/\#\ unixsocket/\unixsocket/g /etc/redis/redis.conf sed -i "s/unixsocketperm 700/unixsocketperm 770/" /etc/redis/redis.conf sed -i "s/# maxclients 10000/maxclients 512/" /etc/redis/redis.conf usermod -aG redis www-data sed -i '$avm.overcommit_memory = 1' /etc/sysctl.conf
Installation des outils:
cd /tmp curl https://download.nextcloud.com/server/releases/latest-22.tar.bz2 -o latest.tar.bz2 tar -xjf latest.tar.bz2 -C /var/www && chown -R www-data:www-data /var/www/ && rm -f latest.tar.bz2 mkdir -p /var/nc_data/ && chown -R www-data:www-data /var/nc_data/
Lancer ces instructions pour installer NextCloud dans la base de donnée.
sudo -u www-data php /var/www/nextcloud/occ maintenance:install --database "mysql" --database-name $DBNAME --database-user $DBUSER --database-pass "$DBPASSWD" --admin-user "admin" --admin-pass "admin" --data-dir "/var/nc_data" sudo -u www-data php /var/www/nextcloud/occ config:system:set trusted_domains 0 --value=cloud.sleto.net sudo -u www-data php /var/www/nextcloud/occ config:system:set overwrite.cli.url --value=https://cloud.sleto.net
Ajouter également ces configuration à la fin du fichier /var/www/nextcloud/config/config.php (avant le ');' final):

Et finaliser la configuration par:
sudo chown www-data:www-data /var/www/nextcloud/config/config.php sudo -u www-data sed -i "s/.*dbhost.*/\'dbhost\' \=\>\ \'localhost\:\/var\/run\/mysqld\/mysqld\.sock\'\,/g" /var/www/nextcloud/config/config.php sudo -u www-data sed -i "s/output_buffering=.*/output_buffering='Off'/" /var/www/nextcloud/.user.ini

Activer la configuration web par:
ln -sf /var/www/nextcloud/nginx-cloud /etc/nginx/sites-enabled
Pour rafraîchir les services fpm, mariadb et nginx
service nginx stop service php7.4-fpm stop service mariadb restart service php7.4-fpm restart service redis-server restart service nginx restart
