Installation d'une solution de collaboration Ethercalc: Feuille de calcul collaborative

ethercalc
Je cherchais depuis un moment, un outil collaboratif.
Je cherche toujours des alternatives aux Géants du Web tels que Google ou Microsoft.
Mais force est de constater qu'il n'existe aujourd'hui pas de réèls concurents à ses solutions...

Le traitement de texte collaboratif que j'utilise est Etherpad, mais en ce qui concerne les feuille de calcul collaborative, c'est une autre paire de manche...

Ethercalc est un système de feuille collaborative open source, ce type d'outil  est tellement rare, qu'il mérite un petit billet.

Ethercalc Logo

EtherCalc est un tableur collaboratif en temps réel. Il permet par défaut à un maximum de seize personnes de partager un texte en cours d'élaboration. Les contributions de chacun apparaissent immédiatement sur l'écran de tous les participants et sont signalées par des couleurs différentes. Une fenêtre de messagerie instantanée est également disponible.

Le système ne requiert aucune installation, ni aucune inscription, il suffit d'avoir une connexion internet et un navigateur web. EtherCalc est écrit en JavaScript.

L'application a été lancée le 19 novembre 2008 par David Greenspan, Aaron Iba et J.D. Zamfirescu (ces deux derniers travaillaient auparavant pour Google).

Le 4 décembre 2009, Google rachète AppJet, la société qui possède le logiciel et il est annoncé que cette application collaborative sera proposée sous licence Open Source1.

Le 17 décembre 2009, Google libère les sources d'EtherCalc sous licence Apache v2.

EtherCalc



Plateforme Materielle :



Comme d'habitude, j'ai monté mon prototype sur ma plateforme de virtualisation:

Dedibox Pro HP
Plateforme logicielle hyperviseur:
  • Dom0 Ubuntu 12.04 X86_64 Xen 4.1
Plateforme Virtuelle:

  • DomU Xen Ubuntu 12.04 X86_64 Paravirtualisé
  • 2 vcpus 
  • 512 Mo de Ram
  • HDD 16GB


Installation:

Pour commencer j'ai mis à jour totalement mon DomU ubuntu 12.04; mon template avait quelques maj de retard :)

  • Mise à niveau du DomU
root@ubuntults:/# apt-get update; apt-get upgrade
root@ubuntults:/# apt-get install linux-headers-server linux-image-server linux-server
root@ubuntults:/# reboot

  • Installation des prérequis
root@antony-linux:/home/antony# apt-get install gzip git-core curl python perl build-essential

  • Installation de node.js
    On télécharge la dernière version de node.js et on la compile
    Attention, ethercalc n'est pour l'instant pas compatible avec node.js v9
    On utilise la version packagée dans ubuntu 12.04 : nodejs_0.6.12
      root@antony-linux:/home/antony# apt-get install nodejs npm

    • Installation de Ethercalc 
    On utilse git pour récupérer la dernière version.
    root@ubuntu:~# cd /opt/
    root@ubuntu:/opt# git clone https://github.com/audreyt/ethercalc.git

    On installe ethercalc:

    C'est bien joli, mais déjà on le lance en root ce qui n'est pas jojo et on est obligé de lancer le script à la main...
    C'est pas très optimisé...

    On crée un user Ethercalc et on donne les droits adéquats.
    root@ubuntults:~# useradd ethercalc

    root@ubuntults:~# chown -R ethercalc /opt/ethercalc


    On crée maintenant un script d'init afin de pouvoir lancer Ethercalc en tant que daemon
    Ce script nous permet de lancer ethercalc en tant que ethercalc et aussi de pouvoir la lancer au demmarage.

    Ethercalc est un outil simple installer, léger,  et agréable à utiliser.
    Bien sur il est bien loin des fonctionnalités de Google Docs ou autres, mais il a le mérite d'exister.
    Pour un usage ponctuel il est très souvent suffisant.
    Surtout le plus important c'est qu'il est installé sur vos serveurs.

    Ethercalc est un moteur, après il faut faire toute l'intégration CMS autour.

    Quelques projets existent déjà:
