[CentOS-announce] Announcing release for Ruby 1.9.3, 2.0.0, 2.2 and Ruby on Rails 3.2, 4.0, 4.1 on CentOS Linux 6 x86_64 SCL

[news 28]

I am pleased to announce the immediate availability versions 1.9.3,

2.0.0, and 2.2 of the Ruby, and versions 3.2, 4.0 and 4.1 of the Ruby on

Rails, now also on CentOS Linux 6 x86_64, delivered via a Software

Collection (SCL) built by the SCLo Special Interest Group

(https://wiki.centos.org/SpecialInterestGroup/SCLo).

 

This is an addition for the Ruby collections that are already available

for CentOS 7

(https://lists.centos.org/pipermail/centos-announce/2015-November/021501.html).

 

QuickStart

----------

You can get started in three easy steps (example of Ruby 2.2 and Ruby on

Rails 4.1):

$ sudo yum install centos-release-scl

$ sudo yum install rh-ruby22 rh-ror41

$ scl enable rh-ruby22 bash

 

At this point you should be able to use ruby just as a normal

application. An examples of commands run might be:

$ ruby my-app.rb

$ gem install activeresource

$ bundle

 

In order to view the individual components included in this

collection, including additional rubygems plugins, you can run:

$ sudo yum list rh-ruby22\* rh-ror41\*

 

The rh-ror41 collection relies on the rh-ruby22 collection and the ror40

collection relies on the ruby200 collection, so the Ruby collections

will be also installed when the Ruby on Rails collection is installed.

 

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 collection rh-ruby22 delivers bundler and version 2.2 of the Ruby

interpreter, while the collection rh-ror41 delivers version 4.1 of the

Ruby on Rails framework that allows to create and run applications in

Ruby or Ruby on Rails framework.

 

The collection ruby200 delivers version 2.0.0 of the Ruby interpreter,

while the ror40 collection delivers version 4.0 of the Ruby on Rails

framework and bundler.

 

The collection ruby193 delivers version 1.9.3 of the Ruby interpreter,

bundler and version 3.2 of the Ruby on Rails framework.

 

Some of the most common rubygems are also included in the collections as

RPMs, the rest may be installed using bundler or gem tools.

 

For more on the Ruby and Ruby on Rails, see https://www.muby-lang.org,

http://rubyonrails.org or https://rubygems.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 Ruby and Ruby on

Rails collections 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.

 

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 SCL's in CentOS.

 

Enjoy!
