How do I install Ruby on an AWS EC2 instance?

Install Ruby on AWS EC2 using RVM (Ruby Version Manager): curl -sSL https://get.rvm.io | bash -s stable, source ~/.rvm/scripts/rvm, then install Ruby: rvm install ruby. Alternatively, use rbenv for version management. For Amazon Linux, you can also use: sudo yum install ruby though this may provide an older version.

What is the best Ruby version manager for AWS?

RVM (Ruby Version Manager) and rbenv are the most popular Ruby version managers for AWS. RVM is feature-rich with gemset support, while rbenv is lighter and integrates better with bundler. Both allow managing multiple Ruby versions on the same server. RVM is more commonly used in development; rbenv is popular in production deployments.

How do I install Ruby on Rails on AWS EC2?

After installing Ruby, install Rails with: gem install rails. Install additional dependencies: sudo yum install gcc make libssl-dev libreadline-dev zlib1g-dev (or Amazon Linux equivalents). Create a new Rails app: rails new myapp, configure Nginx as reverse proxy with Puma as the app server, and configure a systemd service for the Puma server.

What AWS service is best for hosting Ruby on Rails applications?

AWS Elastic Beanstalk is the easiest option for Rails hosting as it handles deployment, scaling, and management automatically with built-in Ruby support. EC2 gives more control but requires manual configuration. For containerized Rails apps, ECS with Docker is popular. AWS Lambda with the Rack adapter works for smaller serverless Rails applications.

How to install Ruby in your AWS Machine? -

January 7, 2021 / Nirav Shah

Ruby is a dynamic, interpreted, reflective, object-oriented, general-purpose programming language. Ruby is most used for building web applications. However, it is a general-purpose language similar to Python, so it has many other applications like data analysis, prototyping, and making proof of concept.

Step 1: Updating System Packages

sudo yum update -y

Step 2: Installing Ruby from the YUM package manager

sudo yum install ruby

Step 3: Check the version

ruby --version

Installing Ruby using Rbenv

It is a lightweight Ruby version management utility which allows you to switch Ruby versions easily.

sudo yum install git wget gcc bzip2 openssl-devel libffi-devel readline-devel zlib-devel gdbm-devel ncurses-devel

install rbenv and ruby-build

wget -q https://github.com/rbenv/rbenv-installer/raw/master/bin/rbenv-installer -O- | bash

add $HOME/.rbenv/bin to our PATH by below command

echo 'export PATH="$HOME/.rbenv/bin:$PATH"' >> ~/.bashrc
echo 'eval "$(rbenv init -)"' >> ~/.bashrc
source ~/.bashrc

rbenv -v

To see Ruby versions,

rbenv install -l

And for verification of ruby version follow below commands

ruby --version

Now you should have a fairly good idea of installing Ruby on your AWS machine. With just a few generic tweaks, you can install Ruby on any Linux distribution.
