Jobsworth

https://github.com/ari/jobsworth/tree/v3.1

Je vais essayer d’écrire un tuto pour installer cette application web écrit en ruby dont je ne connais absolument rien.

La doc officiel commence a dater et les commandes sont souvent dépréciées voir obsolètes et je n’ai pas l’impression que ça soit adapté à Debian.

Installation de rvm (c’est assez long…)

curl -L https://get.rvm.io | bash -s stable --autolibs=enabled --ruby --rails --trace
source /usr/local/rvm/scripts/rvm
rvm all do gem install bundler
rvm reload

Installation de Passenger

rvm all do gem install passenger
rvm all do passenger-install-apache2-module

Noté bien les messages suivant afin de configurer Apache.

The Apache 2 module was successfully installed.

Please edit your Apache configuration file, and add these lines:

   LoadModule passenger_module /usr/local/rvm/gems/ruby-1.9.3-p429/gems/passenger-4.0.5/libout/apache2/mod_passenger.so
   PassengerRoot /usr/local/rvm/gems/ruby-1.9.3-p429/gems/passenger-4.0.5
   PassengerDefaultRuby /usr/local/rvm/wrappers/ruby-1.9.3-p429/ruby

After you restart Apache, you are ready to deploy any number of Ruby on Rails
applications on Apache, without any further Ruby on Rails-specific
configuration!

Ici nous allons modifier le fichier adéquate

vi /etc/apache2/httpd.conf

et ajouter

LoadModule passenger_module /usr/local/rvm/gems/ruby-1.9.3-p429/gems/passenger-4.0.5/libout/apache2/mod_passenger.so
PassengerRoot /usr/local/rvm/gems/ruby-1.9.3-p429/gems/passenger-4.0.5
PassengerDefaultRuby /usr/local/rvm/wrappers/ruby-1.9.3-p429/ruby

Si nécessaire, désactivez le mod passenger par défaut de apache2

a2dismod passenger

Deploying a Ruby on Rails application: an example

Suppose you have a Rails application in /somewhere. Add a virtual host to your
Apache configuration file and set its DocumentRoot to /somewhere/public:

   <VirtualHost *:80>
      ServerName www.yourhost.com
      # !!! Be sure to point DocumentRoot to 'public'!
      DocumentRoot /somewhere/public
      <Directory /somewhere/public>
         # This relaxes Apache security settings.
         AllowOverride all
         # MultiViews must be turned off.
         Options -MultiViews
      </Directory>
   </VirtualHost>

And that's it! You may also want to check the Users Guide for security and
optimization tips, troubleshooting and other useful information:

  /usr/local/rvm/gems/ruby-1.9.3-p429/gems/passenger-4.0.5/doc/Users guide Apache.html

On télécharge via git

cd /var/www
git clone git://github.com/ari/jobsworth.git
cd jobsworth
git checkout v3.1

On configure l’accès à la base de données dans le fichier

cp config/database.example.yml config/database.yml
vi config/database.yml

On se place dans le répertoire racine de ce que l’on vient de télécharger puis on tape la commande suivante :

rvm all do bundle install --without=test development sqlite postgres

Ensuite on crée sa base de données mysql

CREATE DATABASE jobsworth DEFAULT CHARACTER SET utf8 COLLATE utf8_general_ci;
GRANT ALL ON jobsworth.* TO 'user'@'hostname' IDENTIFIED BY 'password'

On s’assure d’être à la racine du projet et on tape

bundle exec lib/setup.rb

On répond aux questions et la 1ere fois on répond y pour Initialize database schema [n]:

On lance ensuite la mise a jour.

./update.sh

Et au cas ou

chown -R www-data.www-data /var/www/jobsworth
service apache2 restart

[root]# which rvm

[root]# which passenger

Au final, rien ne fonctionne, ruby est pour moi une usine à gaz un peu comme nodeJS, ça installe des fichiers de partout sur le système et on a l’impression de ne plus maîtriser ce qu’il se passe.

Je vais donc faire marche arrière et tenter de faire le ménage car ruby prend déjà plus d’1 Go de place…
