ajout tip pour editeur du crontab

Afin de gagner du temps et d'éviter les erreurs humaines, des scripts ont été écrits tout au long du projet. Certains sont même exécutés automatiquement toutes les semaines.

Contenu
taper la commande pour modifier le crontab crontab -e. /!\ Ne pas effectuer cette opération avant de s'être renseigné sur "vi":http://fr.wikipedia.org/wiki/Vi (l'éditeur de texte utilisé qui n'est pas vraiment intuitif :p) et sur "la syntaxe du crontab":http://fr.wikipedia.org/wiki/Crontab#Modification !

h1. Les tâches planifiées

Pour exécuter ces tâches régulièrement, on utilise le "crontab":http://fr.wikipedia.org/wiki/Crontab. Il s'agit d'un programme installé sur notre serveur.

Pour voir et modifier la liste des actions :

se connecter au serveur : `ssh assos@sas1.centrale-marseille`

taper la commande pour voir le crontab `crontab -l`

taper la commande pour modifier le crontab `crontab -e`. /!\ Ne pas effectuer cette opération avant de s'être renseigné sur "vi":http://fr.wikipedia.org/wiki/Vi (l'éditeur de texte utilisé qui n'est pas vraiment intuitif :p) et sur "la syntaxe du crontab":http://fr.wikipedia.org/wiki/Crontab#Modification !¶

{{tip(Pour utiliser un autre editeur que vi taper : export EDITOR=editor_name exemple : vim, nano)}}

Voici la liste des tâches effectuées régulièrement.

h2. La réinitialisation des variables dangeureuses

Sur l'installation d7 principalement : une fois par semaine

Cette tâche consiste à réinitialiser certaines variables qui donnent des droits considérés comme trop permissifs donc dangereux aux administrateurs des sites. En voici la liste :


drushall_atest vset error_level 0 --yes

Cette commande permet de ne pas afficher les messages d'erreurs aux utilisateurs autre que les administrateurs. En effet, ils contiennent parfois des informations sensibles sur l'installation et ne doivent donc pas être divulgués à n'importe qui.


drushall_atest php-eval variable_set\(\'allow_authorize_operations\',FALSE\)\;

Cette commande permet de ne pas autoriser les utilisateurs à installer et mettre à jour des modules via l'interface du site (fonctionnalité introduite dans drupal7). En effet, seul le club Drupal maintient les codes des projet, afin d'en garantir la pérennité.

drushall_atest vset --always-set reverse_proxy TRUE
drushall_atest vset --always-set --format=json reverse_proxy_addresses '["147.94.19.16","147.94.19.17"]'

Ces commandes permettent de déclarer à drupal les serveurs proxy du CRI afin d'éviter qu'il ne répertorie tous les visiteurs comme ayant l'adresse des sus-cités serveurs. Pas fini : voir http://assos.centrale-marseille.fr/content/t%C3%A2che/d%C3%A9clarer-les-proxy-du-cri-%C3%A0-drupal

h3. Comment le lancer ?

N'importe où, taper reinit_var.sh.

h2. La sauvegarde des bases de données

Sur les installations d6 et d7 : une fois par semaine

On utilise les scripts de sauvegarde créés par le club Drupal.

h2. La purge des sauvegardes de bdd

Sur les installations d6 et d7 : toutes les semaines

Cette tâche utilise le script de purge des sauvegardes afin de libérer de l'espace disque en supprimant les sauvegardes de bdd les plus vieilles.

h1. Liste des scripts à disposition

Les scripts utilisés sont hébergés dans le répertoire bin du compte assos.
