Révision 25 (Florent Torregrosa, 04/08/2013 17:16) → Révision 26/118 (Florent Torregrosa, 04/08/2013 17:19)

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.

 h1. Les tâches planifiées 

 h2. Crontab 

 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 : <code>ssh assos@sas1.centrale-marseille</code> 
 # taper la commande pour voir le crontab <code>crontab -l</code> 
 # taper la commande pour modifier le crontab <code>crontab -e</code>. /!\ 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)}} 

 <pre> 
 <code class="php"> 
 Ici bientôt le crontab 
 </code> 
 </pre> 

 h3.  

 Voici la liste des tâches effectuées régulièrement. 

 

 h2. La réinitialisation des variables 

 Cette tâche consiste à réinitialiser certaines variables qui donnent des droits considérés comme trop permissifs donc dangereux aux administrateurs des sites ou nécessaire pour d'autres scripts tels que piwik ou security_review. 

 En voici quelques exemples : 

 <pre> 
 <code class="bash"> 
 drush -y vset error_level 0 
 </code> 
 </pre> 

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

 <pre> 
 <code class="php"> 
 drush -y vset --always-set reverse_proxy TRUE 
 drush -y vset --always-set --format=json reverse_proxy_addresses '["147.94.19.16","147.94.19.17"]' 
 </code> 
 </pre> 

 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 serveurs sus-cités. **Pas fini : voir http://assos.centrale-marseille.fr/content/t%C3%A2che/d%C3%A9clarer-les-proxy-du-cri-%C3%A0-drupal** 

 

 h2. La sauvegarde des bases de données 

 Sur les installations d6 et d7 : une fois par semaine 

 On utilise les [[Scripts_et_taches_planifiees#Tout-sauvegarder|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 [[Scripts_et_taches_planifiees#purge_des_sauvegardes.sh|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.
