Nextcloud est une application de stockage de fichiers en ligne.

Nous installons Nginx

sudo aptitude install nginx

Le dernier paquet Nexcloud se trouve à cette adresse : https://nextcloud.com/install/#instructions-server
Nous récupérons l'archive Nextcloud

wget https://download.nextcloud.com/server/releases/latest.zip

Nous le décompressons

unzip nextcloud-16.0.4.zip

Nous le renommons, lui donnons les bons droits et le plaçons dans /var/www

mv nextcloud cloud.grohub.org
sudo chown -R www-data: cloud.grohub.org
sudo mv cloud.grohub.org /var/www

Nous créons le fichier vHost

sudo vi /etc/nginx/sites-available/cloud.grohub.org

Nous y ajoutons ce contenu

Nous créons le lien symbolique dans /etc/nginx/sites-enabled

cd /etc/nginx/sites-enabled
sudo ln -s /etc/nginx/sites-available/cloud.grohub.org

Nous installon PHP-fpm et les différents modules dont nous aurons besoin

sudo aptitude install php7.3-fpm php-apcu php-apcu-bc php7.3-mysql php7.3-zip php7.3-dom php7.3-xml php7.3-ldap php7.3-curl php7.3-mbstring php7.3-gd php7.3-intl php7.3-imagick

Nous réglons le temps maximal d'exécution pour éviter les timeout dans le fichier /etc/php/7.3/fpm/php.ini

max_execution_time = 300

Dans le fichier /etc/php/7.3/fpm/pool.d/nextcloud.conf nous saisissons ces éléments

[nextcloud]
listen = /run/php/nextcloud.sock

listen.owner = www-data
listen.group = www-data

user = www-data
group = www-data

pm = dynamic
pm.max_children = 120
pm.start_servers = 12
pm.min_spare_servers = 6
pm.max_spare_servers = 18

env[HOSTNAME] = $HOSTNAME
env[PATH] = /usr/local/bin:/usr/bin:/bin
env[TMP] = /tmp
env[TMPDIR] = /tmp
env[TEMP] = /tmp

Nous activons opcode. Toujours dans le fichier /etc/php/7.3/fpm/php.ini, nous recherchons ces clés et enlevons les commentaires our les activer

opcache.interned_strings_buffer=8
opcache.max_accelerated_files=10000
