Installation de Ruby 2.0 et Rails 4.0.0beta sur AWS EC2)

L'installation de Ruby 2.0.0 et Rails 4.0.0beta1 sur l'installation par défaut d'Amazon EC2 Linux (Amazon Linux AMI 2012.09.1) se passe bien. Mais openssl entre la façon (par exemple http://railsapps.github.com/openssl-certificate-verify-failed.html ) et bizarre soit d'empêcher openssl d'être installé ou de faire installer le gestionnaire de paquets RubyGem par Rails.

Comment contourner ces problèmes?

et usurper l'identité de la racine:

$ Sudo su -

Vous êtes connecté en tant que root à partir d'ici. Appliquez les mises à jour du serveur:

[root@ip-xx ~]# yum update

Maintenant, c'est là qu'elle diffère de la solution standard. Installez RVM mais sans distribution de Ruby:

[root@ip-xx ~]# \curl -L https://get.rvm.io | bash -s stable

Installing RVM to /usr/local/rvm/
    Creating group 'rvm'

# RVM:  Shell scripts enabling management of multiple Ruby environments.
# RTFM: https://rvm.io/
# HELP: http://webchat.freenode.net/?channels=rvm (#rvm on irc.freenode.net)
# Cheatsheet: http://cheat.errtheblog.com/s/rvm/
# Screencast: http://screencasts.org/episodes/how-to-use-rvm

# In case of any issues read output of 'rvm requirements' and/or 'rvm notes'

Installation of RVM in /usr/local/rvm/ is almost complete:

  * First you need to add all users that will be using rvm to 'rvm' group,
    and logout - login again, anyone using rvm will be operating with `umask u=rwx,g=rwx,o=rx`.

  * To start using RVM you need to run `source /etc/profile.d/rvm.sh`
    in all your open Shell windows, in rare cases you need to reopen all Shell windows.

# root,
#
#   Thank you for using RVM!
#   I sincerely hope that RVM helps to make your life easier and
#   more enjoyable!!!
#
# ~Wayne

Vérifions qu'aucune version Ruby n'est installée:

[root@ip-xx ~]# rvm list

rvm rubies


# No rvm rubies installed yet. Try 'rvm help install'.

Maintenant, openssl est déjà installé sur le système mais est incompatible avec la configuration:

[root@ip-xx ~]# openssl version
OpenSSL 1.0.0k-fips 5 Feb 2013

[root@ip-xx ~]# openssl version -d
OPENSSLDIR: "/etc/pki/tls"

Toute tentative d'installation de Ruby2 avec cette version entraînera l'erreur suivante:

[root@ip-xx ~]# rvm install 2.0.0 -- --with-openssl-dir=/etc/pki/tls

Voici une variante avec rbenv.

SSH dans votre toute nouvelle instance:

Emprunter l'identité de la racine et appliquer les mises à jour du serveur:

$> Sudo su -
$> yum update

Installez quelques packages:

$> yum install git pcre pcre-devel

Clone rbenv :

$> git clone git://github.com/sstephenson/rbenv.git /usr/local/rbenv

Créez le fichier suivant:

# /etc/profile.d/rbenv.sh
export RBENV_ROOT=/usr/local/rbenv
export PATH="${RBENV_ROOT}/bin:$PATH"
eval "$(rbenv init -)"

Installer Ruby-build :

$> . /etc/profile
$> git clone https://github.com/sstephenson/Ruby-build.git /usr/local/rbenv/plugins/Ruby-build

Installez Ruby:

$> rbenv install 2.0.0-p195  # wait ...
$> rbenv global 2.0.0-p195
$> rbenv rehash

Mettre à jour rubygems et installer passager:

$> gem update --system
$> gem install bundler     
$> gem install passenger

Installez nginx par le passager:

$> passenger start

Au moment d'écrire ces lignes, la dernière version de passager est 4.0.0, qui fonctionne avec Ruby 2.0.0.

Elastic Beanstalk Si vous utilisez Elastic Beanstalk, arrêtez le passager

$> Sudo service passenger stop

Initialisez rbenv en ajoutant ce qui suit à /opt/elasticbeanstalk/support/envvars.d/appenv

. /etc/profile.d/rbenv.sh

Démarrer le passager

$> Sudo service passenger start
