How To Install Ruby on Rails with rbenv on CentOS 7

Ruby on Rails, or simply Rails, is a web application framework written in Ruby under MIT License. Rails is a model–view–controller (MVC) framework, providing default structures for a database, a web service, and web pages. It encourages and facilitates the use of web standards such as JSON or XML for data transfer, and HTML, CSS and JavaScript for display and user interfacing. In addition to MVC, Rails emphasizes the use of other well-known software engineering patterns and paradigms, including convention over configuration (CoC), don’t repeat yourself (DRY), and the active record pattern.
