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:

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.
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.
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.
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.
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.

Check that the binary exists and returns the expected version:
```
/opt/alt/<ruby-version>/bin/ruby -v
```
Optionally, add it to PATH to use it as default:
```
export PATH=/opt/alt/<ruby-version>/bin:$PATH
ruby -v
which ruby
```
Update packages
```
yum update 'alt-ruby*'
```
