Installing Rails 2.3 LTS with Bundler

This document describes how to swap out the official Rails 2.3 gems with Rails 2.3 LTS. If you have installed Rails LTS before and want to update to a newer version, please see our update instructions.

Prerequisites

  1. Make sure your project satisfies the system requirement for Rails LTS. This involves upgrading to Rails 2.3.18.

  2. The instructions below assume you are using Bundler to manage your gem dependencies.
    If your project isn't using Bundler, you can either upgrade to Bundler (recommended) or
    install Rails 2.3 LTS without Bundler.

  3. Make sure that you have a current version of Rubygems and Bundler, otherwise you might run into random errors with dependency resolution.

If you use Ruby 1.8.7, we recommend using

  • rubygems version 1.8.30
  • bundler version 1.17.3

On newer Rubies, you can use more modern versions of Rubygems and Bundler.

To update, run

Copy
gem update --system 1.8.30 gem install bundler -v '1.17.3'

If you get an error "No gem names are allowed with the --system option" trying to update Rubygems, you can instead do this:

Copy
gem uninstall rubygems-update # (uninstall all versions) gem install rubygems-update -v 1.8.30 update_rubygems gem install bundler -v '1.17.3'

Installation

  1. Open the Bundler configuration file (Gemfile) in your project's root directory and find this line:

    Copy
    gem 'rails'

    As a customer of a paid plan (Startup, Standard, Enterprise), replace that line with the following code:

    Copy
    source 'https://username:password@gems.railslts.com' do gem 'rails', '~>2.3.18' gem 'actionmailer', :require => false gem 'actionpack', :require => false gem 'activerecord', :require => false gem 'activeresource', :require => false gem 'activesupport', :require => false gem 'railties', :require => false gem 'railslts-version', :require => false end

    Replace username and password with your personal credentials that you received after subscribing to Rails LTS.
    Make sure a colon (:) separates username and password.

    As a subscriber to the free Community edition, use the following code instead:

    Copy
    git 'https://github.com/makandra/rails.git', :branch => '2-3-lts' do gem 'rails', '~>2.3.18' gem 'actionmailer', :require => false gem 'actionpack', :require => false gem 'activerecord', :require => false gem 'activeresource', :require => false gem 'activesupport', :require => false gem 'railties', :require => false gem 'railslts-version', :require => false end

    You will not need a username or password for the Community edition.

    Note that our repositories are available via SSL (https) only, http://... will not work.

  2. Open config/environment.rb within your project directory and delete the following line:

    Copy
    RAILS_GEM_VERSION = '2.3.xx' unless defined? RAILS_GEM_VERSION
  3. Run Bundler to complete the installation:

    Copy
    bundle update rails

    If the clone process aborts with an error like "The requested URL returned error: 403" or "Cannot get remote repository information" your Git version is probably too old. In such case you should upgrade your Git to version 1.7+ or you can install Rails LTS without Bundler.

  4. Decide whether to enable optional security enhancements shipped with Rails LTS.

    In order to keep maximum compatibility to the official Ruby on Rails releases, Rails LTS disables all additional security features by default. We do however recommend the :hardened configuration, which includes improvements we believe to be reasonable defaults for increased security in most applications.

  5. Confirm that you are running the latest version of Rails 2.3 LTS.

  6. Follow your normal release process (run tests, push, deploy to staging, do smoke testing, deploy to production).

Congratulations! You successfully deployed your application using Rails LTS. If you have chosen to subscribe to the Rails LTS Notification List when signing up, you will be notified whenever a new patch for Rails LTS becomes available.
