Nextcloud dans un conteneur LXC
Article détaillé sur l'installation de nextcloud 17 dans un conteneur lxc.
Je pars d'une Debian Buster.
# lxc-create -t download -n nextcloud -- --dist debian --release buster --arch amd64
Configuration (on rajoute le démarrage automatique) :
# vim /var/lib/lxc/nextcloud/config # cat /var/lib/lxc/nextcloud/config lxc.start.auto = 1 # Distribution configuration lxc.include = /usr/share/lxc/config/common.conf lxc.arch = linux64 # Container specific configuration lxc.rootfs.path = dir:/var/lib/lxc/nextcloud/rootfs lxc.uts.name = nextcloud # Network configuration lxc.net.0.type = veth lxc.net.0.link = lxcbr0 lxc.net.0.flags = up lxc.net.0.hwaddr = 00:16:3e:c8:1b:05
Pour l'IP fixe :
# vim /etc/lxc/dnsmasq.conf (...) dhcp-host=nextcloud,10.0.3.4
On redémarrer le service :
# systemctl restart lxc-net
Et on démarre le conteneur :
# lxc-start nextcloud # lxc-ls -f NAME STATE AUTOSTART GROUPS IPV4 IPV6 UNPRIVILEGED (...) nextcloud RUNNING 1 - 10.0.3.4 - false
Installation des prérequis
# lxc-attach nextcloud root@nextcloud:/# apt install nginx php-fpm mariadb-server wget curl unzip
Script "setup-nextcloud.php"
root@nextcloud:/# mkdir /var/www/nextcloud root@nextcloud:/# cd /var/www/nextcloud root@nextcloud:/var/www/nextcloud# wget https://download.nextcloud.com/server/installer/setup-nextcloud.php
Il faut changer la version de nextcloud dans le script parce que par défaut elle est encore en 16.0.3 à l'heure où j'écris ces lignes.
root@nextcloud:/var/www/nextcloud# vim setup-nextcloud.php (...) // Nextcloud version define('NC_VERSION', '17.0.0'); (...) root@nextcloud:/var/www/nextcloud# cd .. root@nextcloud:/var/www# chown -R www-data:www-data nextcloud/
Il faut configurer nginx pour qu'il pointe sur ce dossier :
root@nextcloud:/var/www# cat /etc/nginx/sites-enabled/default server { listen 80 default_server; root /var/www/nextcloud; # Add index.php to the list if you are using PHP index index.html index.htm index.php; server_name _; location / { try_files $uri $uri/ =404; } # pass PHP scripts to FastCGI server location ~ \.php$ { include snippets/fastcgi-php.conf; fastcgi_pass unix:/run/php/php7.3-fpm.sock; } }
On relance nginx :
root@nextcloud:/var/www# systemctl reload nginx
J'ai voulu utiliser le script “setup-nextcloud.php” mais j'ai eu d'abord pas mal de timeout (j'ai augmenté les temps sur le proxy et sur le nginx du container) et puis à la fin j'arrive sur une 404 donc quelque chose se passe mal. Je laisse la procédure pour mémoire :
À installer :
root@nextcloud:/var/www# apt install php-zip php-xml php-curl php-mbstring php-mysql
Création de la DB
root@nextcloud:/var/www# mysql -u root -p Enter password: Welcome to the MariaDB monitor. Commands end with ; or \g.

Problèmes rencontrés
Problèmes de droits pour MariaDB
J'ai eu un problème avec MariaDD qui ne pouvait pas démarrer parce que le service ne pouvait pas écrire dans “ibdata1” :

"Infinite loop" on login
Il y a un problème de droits sur le dossier /var/lib/php/ alors php ne sait pas créer de session :
root@nextcloud:/var/www/nextcloud# chown -R www-data:www-data /var/lib/php/ root@nextcloud:/var/www/nextcloud# ls -al /var/lib/php/sessions/ total 8 drwx--x--t 2 www-data www-data 4096 Oct 19 18:32 . drwxr-xr-x 4 www-data www-data 4096 Oct 19 18:32 ..
Quand on se connecte :
root@nextcloud:/var/www/nextcloud# ls -al /var/lib/php/sessions/ total 8 drwx--x--t 2 www-data www-data 4096 Oct 22 10:00 . drwxr-xr-x 4 www-data www-data 4096 Oct 19 18:32 .. -rw------- 1 www-data www-data 0 Oct 22 10:00 sess_27fb89n013eghaa8k8g0b01lir
