This document describes how to swap out the official Rails 2.3 gems with Rails 2.3 LTS Show archive.org snapshot . If you have installed Rails LTS before and want to update to a newer version, please see our update instructions Show archive.org snapshot .
Make sure your project satisfies the system requirement for Rails LTS. This involves upgrading to Rails 2.3.18.
The instructions below assume you are using
Show archive.org snapshot
to manage your gem dependencies.
If your project isn't using Bundler, you should upgrade to Bundler Show archive.org snapshot .
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
On newer Rubies, you can use more modern versions of Rubygems and Bundler.
To update, run
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:
gem uninstall rubygems-update # (uninstall all versions) gem install rubygems-update -v 1.8.30 update_rubygems gem install bundler -v '1.17.3'
Open the Bundler configuration file (
Gemfile) in your project's root directory and find this line:
As a customer of a paid plan (Startup, Standard, Enterprise), replace that line with the following code:
source 'https://username:email@example.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 gem 'rack', :require => false end
password with your personal credentials that you received after subscribing to Rails LTS.
Make sure a colon (
:) separates username and password.
If you don't want these credentials in your Gemfile, you can either
bundle config set gems.railslts.com username:password
In this case, just use

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 gem 'rack', :require => false end

config/environment.rb within your project directory and delete the following line:
RAILS_GEM_VERSION = '2.3.xx' unless defined? RAILS_GEM_VERSION
Run Bundler to complete the installation:
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
Show archive.org snapshot
. In such case you should upgrade your Git to version 1.7+ or you can install Rails LTS without Bundler.
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.
Confirm that you are running the latest version of Rails 2.3 LTS.
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.
If you have trouble using the mysql gem, you should try upgrading to mysql2 which is mostly a drop-in replacement. We suggest you use our fork on mysql2 which fixes some compilation issues on newer linux distros, by adding this to your Gemfile:
gem 'mysql2', git: 'https://github.com/makandra/mysql2', branch: '0.2.x-lts'
Also, in your
database.yml, change the adapter to
