CentOS announce - Mar 2016 - Announcing release of Ruby on Rails 4.2 on CentOS Linux 7 x86_64 SCL

I am pleased to announce the immediate availability of Ruby on Rails
4.2 on CentOS Linux 7 x86_64, delivered via a Software Collection
(SCL) built by the CentOS SCLo Special Interest Group
(https://wiki.centos.org/SpecialInterestGroup/SCLo).

QuickStart
----------
You can get started in three easy steps:
   $ sudo yum install centos-release-scl
   $ sudo yum install sclo-ror42
   $ scl enable sclo-ror42 bash

At this point you can use Ruby on Rails in the usual way with the
`rails` command. Examples of commands might be:
   $ rails new --skip-bundle example
   $ rails generate model Article

'byebug' and 'webconsole' development dependencies are not
supplied, so
should be removed from generated Gemfiles.

In order to compile assets, uncomment or add the gem 'therubyracer' to
the application Gemfile. Add the v8314 SCL to use this supplied gem:
   $ scl enable sclo-ror42 v8314 bash

To deploy an application under Passenger, see the wiki documentation:
https://wiki.centos.org/SpecialInterestGroup/SCLo/RubyOnRails

About Software Collections
--------------------------
Software Collections give you the power to build, install, and use
multiple versions of software on the same system, without affecting
system-wide installed packages. Each collection is delivered as a group
of RPMs, with the grouping being done using the name of the collection
as a prefix of all packages that are part of the software collection.

The sclo-ror42 collection delivers Ruby on Rails version 4.2.5.1,
modelled on previous collections (e.g. rh-ror41) and provides all of
Rails with full asset compilation support, plus extras such as jQuery
(1.11.2 & 2.1.3). It depends on the rh-ruby22 and v8314 collections.

For more on Ruby on Rails, see http://rubyonrails.org/.

The SCLo SIG in CentOS
----------------------
The Software Collections SIG group is an open community group
co-ordinating the development of the SCL technology, and helping curate
a reference set of collections. In addition to the Rails collection
released here, we also build and deliver databases, web servers, and
language stacks including multiple versions of PostgreSQL, MariaDB,
Apache HTTP Server, NodeJS, Ruby, Python and others.

Software Collections SIG release was announced at
https://lists.centos.org/pipermail/centos-announce/2015-October/021446.html

You can learn more about Software Collections concepts at:
http://softwarecollections.org
You can find information on the SIG at
https://wiki.centos.org/SpecialInterestGroup/SCLo ; this includes howto
get involved and help with the effort.

We meet every second Wednesday at 16:00 UTC in #centos-devel (ref:
https://www.centos.org/community/calendar), for an informal open forum
open to anyone who might have comments, concerns or wants to get started
with SCLs in CentOS.
