CentOS announce - Jul 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 in 
version 4.2 on CentOS Linux 7 x86_64, delivered via a Software 
Collection (SCL) built by the 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 rh-ror42
      $ scl enable rh-ror42 rh-nodejs4 bash

At this point you should be able to use rails just as a normal 
application. Here are some examples of commands you can run:
      $ rails new project
      $ cd project
      $ rails server -p 8080
      $ rails generate controller pages

In order to view the individual components included in this collection, 
you can run:
      $ sudo yum list rh-ror42\*

Last but not least you can try this Software Collection in Docker. You 
can pull the image with the following command:
      $ sudo docker pull centos/ror-42-centos7

For more on the docker image follow the link to public source 
repository: https://github.com/sclorg/ror-container

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 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 collection Ruby on 
Rails being released here, we also build and deliver databases, web 
servers, and language stacks including multiple versions of PostgreSQL, 
MariaDB, Apache HTTP Server, NodeJS, Python and others.

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.

Enjoy!
