Brief introduction The Ruby on Rails framework has been widely watched since its inception and, guided by ideas like "Don't repeat Yourself" and "contract is superior to configuration", rails gives Web developers a very high level of development efficiency. ActiveRecord's flexibility allows you to use a very easy-to-use Hibernate without cumbersome configuration, Github and Rubygems's rich and varied

centralize logging on CentOS 7 using Logstash and Kibana Centralized logging is useful when trying to identify a problem with a server or application because it allows you to search all logs in a single location.
