# About ALT-Ruby

alt-ruby is a component provided by TuxCare designed for managing Ruby versions on servers and enabling users to run multiple Ruby versions simultaneously.

Here are the key features and characteristics of alt-ruby:

1. Multiple Ruby Versions - alt-ruby allows the installation and usage of various Ruby versions on a single server. This enables users to select the Ruby version that best suits their applications.

2. User Segmentation - alt-ruby allows administrators to provide different Ruby versions for different users or applications. Each user can choose the Ruby version that suits their project.

3. Enhanced Compatibility - alt-ruby is designed to ensure maximum compatibility with various Ruby applications and frameworks. This includes optimizations and changes to make it compatible with a wide range of Ruby applications.

4. Updates and Support - TuxCare provides regular updates for alt-ruby, including bug fixes, performance improvements, and updates for new Ruby versions. This helps ensure the security and currency of Ruby usage.

5. Easy Version Switching - alt-ruby allows switching between versions, users can easily manage which Ruby version is active in their environment.

alt-ruby provides a more flexible and convenient environment for working with different Ruby versions on a single server, which is particularly useful in development and production environments where multiple applications have varying requirements for Ruby versions.

# Installation Instructions

1. Download the installer script:

   wget https://repo.alt.tuxcare.com/alt-ruby-els/install-els-alt-ruby-deb-repo.sh
   

2. Run the installer script with your key. The installation script registers the server to CLN with the key, and adds our PGP key and repository to the server.

   bash install-els-alt-ruby-deb-repo.sh --license-key XXX-XXXXXXXXXXXX
   

   After the repository is added, you can install packages using standard commands.

3. Install Ruby package and use specific versions.

   • To install a specific version only (for example, alt-ruby27):

     apt-get install alt-ruby27
     

   • To find out which packages are available for installation, use the following command:

     apt list -a | grep alt-ruby
     

   Using alt-ruby versions:

   alt-ruby versions are intended to be installed alongside the system's default ruby and allow multiple versions to coexist. To use a specific alt-ruby version, please run it directly from its installation directory, for example:

   source /opt/alt/alt-ruby27/enable
   ruby -v 
   

4. Update installed packages when updates are available:

   apt-get update
   apt-get --only-upgrade install alt-ruby*
