Bonjour,

Pouvez-vous me donner votre NIC OVH afin que je regarde plus en détails ?

Pour information, j'ai fait une installation complète de drupal 8.4 sans rencontrer de problème.

Ci-dessous les traces de mon installation :

    ~$ curl -o drupal-8.4.0.tar.gz https://ftp.drupal.org/files/projects/drupal-8.4.0.tar.gz
    ~$ tar xzf drupal-8.4.0.tar.gz --strip 1 -C www/
    ~$ php -r "copy('https://getcomposer.org/installer', 'composer-setup.php');"
    ~$ php -r "if (hash_file('SHA384', 'composer-setup.php') === '544e09ee996cdf60ece3804abc52599c22b1f40f4323403c44d44fdfdd586475ca9813a858088ffbc1f233e9b180f061') { echo 'Installer verified'; } else { echo 'Installer corrupt'; unlink('composer-setup.php'); } echo PHP_EOL;"
    Installer verified
    ~$ php composer-setup.php
    All settings correct for using Composer
    Downloading...

[DidierM]

Bonjour Arnaud.

Merci pour le test.
Je vais comparer avec mon installation D8.4.0.
Il y a peut-être des paramètres différents (Composer ? Json ? je ne maîtrise pas encore entièrement)

Je te passe notre ID en privée.
Didier

[DidierM]

ma commande Composer pour l'installation n'est pas la même :

composer create-project drupal-composer/drupal-project:8.x-dev public_html --stability dev --no-interaction

"public_html" est remplacé par le dossier dans le home de notre Cloud Web.

doc
https://commerceguys.fr/blog/drupal8-et-composer-un-mariage-reussi
La commande indiquée correspond bien à ce que nous avons utilisé :
composer create-project drupal-composer/drupal-project:8.x-dev some-dir --stability dev --no-interaction

ça correspond aussi à la doc d'installation, option A, du site drupal.org :

Using Composer to manage Drupal site dependencies

Merci. Didier

[ArnaudF2]

Ok merci, je test ta procédure. Je te fais un retour rapidement

Arnaud

[ArnaudF2]

Didier,

je viens d'ajouter 1G de swap ( pris dans ton homez, il te reste donc 14G au lieu de 15G) sur ton cloudweb.

Peux tu réessayer l'installation de Drupal via composer ?

Une fois l'installation terminée je pourrais supprimer le swap afin que tu récupères les 1G utilisés par le swap.

On étudie la possibilité d'une option dans le manager pour l'ajout / suppression de swap.

Pour finir, as tu réellement besoin de la version de dev de drupal, ne serait-il pas préférable d'utiliser la dernière version stable de drupal ?

Arnaud

[DidierM]

Bonjour Arnaud

Je vais tester.
Je n'utilise pas la version Dev de Drupal.
Le Drupal installé est D8.4.0, la dernière stable sortie il y a 1 semaine environ.

La commande Composer utilise le mot "dev", mais c'est une référence (je crois) au fait que le niveau minimum des modules doit être Dev (et pas Alpha, etc).

C'est en tout cas la commande Composer d'install donnée dans les doc Drupal, pour un Drupal STABLE de Prod.

Merci. Didier

[DidierM]

OK
ça passe !

Swap: 1048572 148832 899740

Donc, l'install des modules (j'en ai mis plusieurs) à pris au maximum 149 MB de swap.

Je ne comprend toujours pas pourquoi Composer, qui est supposé ne faire que gérer des fiches sources PHP, n'a pas assez avec 2 GB !

Si tu supprimes le swap, nous ne pourrons plus installer d'autres modules... ni donc d'autres sites Drupal 8...

---

Je vais faire un test avec ta commande d'installation sur mon Cloud Web perso (là c'était celui d'Eric)
et voir ce qui change...
Car si vraiment on y arrive avec 2GB, ce serait bien.

Merci. Didier

[janus57]

Bonjour,

question : pourquoi ne pas utiliser une des autres option d'install pour voir si elle consomme moins (preuve avec l'installation de @ArnaudF2 ) ?

Cordialement, janus57

[DidierM]

Bonjour Janus
C'est exactement ce que je suis en train de faire.
Je veux voir le résultat, et si la structure des dossiers Drupal 8 est différente ou pas.

Didier

[DidierM]

~/composer.phar --profile install

L'ajout de module Drupal 8 passe avec ta procédure, sur mon Cloud Web 2 GB (sans le swap file).
Mais je vais encore refaire un test.

Avec ta procédure, je n'ai pas la même structure de dossiers Drupal.
ça me dérange un peu (mais ce n'est pas "mortel"), car moins bien organisé
et aussi car je crois que lors d'un "composer update", ça ne mettra pas à jour les fichiers à la racine Drupal.
(il y a des expli sur cela sur le site Drupal)

MAIS... je me demande si mon problème ne vient pas du fait que j'ai fait ma commande "composer" pour installer Drupal 8.4.0
mais JAMAIS fait la commande

~/composer.phar --profile install

Je vais refaire ma procédure, mais en ajoutant ça !
Si c'est ça mon erreur, alors Composer consommerait nettement moins.

Je refais ce test et je vous tient au courant.

Merci. Didier

[janus57]

Bonjour,

sinon il reste les options B et C de la doc drupal (visiblement la C est équivalente à la A en terme de "fonctionnalités").

Cordialement, janus57

Je dois modifier dans le manager OVH pour avoir la racine du site dans

/cloudweb2/web

Le code Drupal est dans le sous-dossier /web

Ensuite je fais la config Drupal DB standard via le web.

Puis je fais l'installation d'un module :

et ça coince !

composer require drupal/pathauto

-bash: composer: command not found

... je ne comprend pas comment ce changement de config des dossiers, et l'ajout de certains composants telque Drush, fait que Composer BOUFFE la mémoire comme cela !

bon, je vais essayer de m'adapter à l'autre structure de dossiers (celle que tu as utilisée), qui consomme nettement moins de ram.

Merci. Didier

[DidierM]

l'option d'installation C pour Drupal 8 "hussainweb/drupal-composer-init" ?

Oui, je vais la tester.
Je ne comprend pas la quantité de RAM bouffée par l'installation A.

Marre de Composer !
Pourquoi ça bouffe autant de ram pour donwloader des fichiers source PHP ?

Merci. Didier

[SteveO]

Si ça peut aider, J'ai réussi à ajouter des modules via composer en stoppant les services apache et mysql:

sudo systemctl stop apache2.service
sudo systemctl stop mysql.service

un peu radicale, mais j'ai pu donwloader mes modules qui me manquaient...

composer require drupal/robotstxt
composer require drupal/backup_migrate

puis redémarrage des services:

sudo systemctl start apache2.service
sudo systemctl start mysql.service

[CM63]

Bonne astuce, merci. Mais effectivement on se demande pourquoi Composer a besoin d'autant de mémoire. Il cache les fichiers ou quoi? Si oui, pour un téléchargement one shot on voit pas bien à quoi ça sert.

[DidierM]

oui, intéressant pour un VPS par exemple.
Mais avec OVH Cloud Web, on n'a pas la possibilité de faire un "stop apache" ...
;-)

[DidierM]

Mais effectivement on se demande pourquoi Composer a besoin d'autant de mémoire. Il cache les fichiers ou quoi?

C'est une très bonne question !
Je me demande aussi pourquoi Composer à besoin de tant de mémoire.
Composer avec drupal "tout seul" ça semble aller...
mais si tu installes un projet plus complet, du genre :

composer create-project drupal-composer/drupal-project:8.x-dev my_site_name_dir --stability dev --no-interaction

alors, là, ça bouffe de la RAM ...
