How to install Ruby on Rails on Ubuntu Server

The Issue

If you seeing this then you are probably looking for guidance on how to install ruby on rails on Ubuntu server for the production environment.

If so then keep reading because the solution would be here
I would also cover installing the Elasticsearch server, integrate it with the rails app so you could add search functionality to your app easily

You should already know what is Ubuntu server and what is rails application so I’ll try to be concise as much as I can.

Important Notes

• The first important note about this integration is the version number, You should stick with it exactly as it is, any change would make a conflict later which would cause a severe impact on the installation.
• In this code you would get to know how to install ruby gems on ubuntu, I would use rvm to install rails on the ubuntu server and the ubuntu server version 18.04 LTS.
• Please don’t forget to stick with the rvm versions, any gems versions, and Elasticsearch version so you can integrate them successfully.
• I would use Nginx as a server because it’s easier to debug.
• Some of this code is related to some specific gems that related to my app like gem ‘acts-as-taggable-on’
• Feel free to exclude it, also I would like to point at something in this command RAILS_ENV=production rake searchkick:reindex CLASS=Element.
• Element in my application is the model that I would like to use the search function. If you want to use it for User, just change it. You can index as many models as you want.
• Finally, I would like to point a very important thing which is the server requirement. You need at least 2GB RAM to make this work, 1 GB for the rails application and the other for the Elasticsearch engine.
