I am pleased to announce the immediate availability of Ruby in version
2.5 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).

You can get started in three easy steps:

    # 1. Install a package with repository for your system:
    # On CentOS, install package centos-release-scl available in CentOS
    $ sudo yum install centos-release-scl

    # On RHEL, enable RHSCL repository for you system:
    $ sudo yum-config-manager --enable rhel-server-rhscl-7-rpms

    # 2. Install the collection:
    $ sudo yum install rh-ruby25

    # 3. Start using software collections:
    $ scl enable rh-ruby25 bash

The last command runs the Bash shell in the environment with rh-ruby25
Software Collection enabled, which means that at this point you are able
to use ruby just as a normal application. Some examples of available
commands follow:

    $ ruby my-app.rb
    $ gem install activeresource
    $ bundle
    $ irb

This collections is CentOS-based rebuild built by SCLo SIG community,
and the packages have been available in Red Hat Software Collections 3.1
for RHEL:


So, for RHEL-based builds, follow the steps in the documentation above.

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

You can find information on the SIG at
https://wiki.centos.org/SpecialInterestGroup/SCLo ;
this includes how to get involved and help with the effort.
