Installing Ruby on Rails on Your VPS

Overview

Ruby on Rails, often simply Rails, is a server-side webapplication framework written in Ruby under the MIT License. It is a model-view-controller(MVC) framework, providing default structures for a database, a web service,and web pages. This guide will walk you through the process of installing Rubyon Rails on your Virtual Private Server (VPS) with HSJ.HOST, enabling you todevelop powerful web applications.

Prerequisites

• A VPS account with HSJ.HOST.
• SSH access to your server.
• Basic knowledge of the Linux command line.
     
     

Procedure

1. Access Your VPS via SSH

• Open a terminal and connect to your VPS: ssh user@your_vps_ip, replacing user with your username and your_vps_ip with the IP address of your server.
     
     

2. Update Your Server's Package List

• Ensure your server's package list is up to date: sudo apt update and then sudo apt upgrade to update all installed packages to their latest versions.
     
     

3. Install Ruby

• Install Ruby through the package manager:
     
     

sql code

sudo apt install ruby-full

• Verify the installation by checking the Ruby version:
     
     

css code

ruby --version

4. Install SQLite3

• Rails typically uses SQLite3 as its default database for development:
     
     

code

sudo apt install sqlite3 libsqlite3-dev

• Verify the installation by checking the SQLite3 version:
     
     

css code

sqlite3 --version

5. Install Node.js and Yarn

• Rails 6 and above require Node.js and Yarn for managing JavaScript code and dependencies:

 
• Install Node.js:
       
       

code

sudo apt install nodejs

 
• Install Yarn:
       
       

bash code

curl -sS https://dl.yarnpkg.com/debian/pubkey.gpg | sudoapt-key add - echo "deb https://dl.yarnpkg.com/debian/ stable main" |sudo tee /etc/apt/sources.list.d/yarn.list sudo apt update && sudo aptinstall yarn

6. Install Rails

• With Ruby installed, you can now install Rails. It's recommended to use the gem package manager for Ruby to install Rails:
     
     

code

gem install rails

• After installation, verify the Rails version:
     
     

css code

rails --version

7. Create Your First Rails Application

• Now that Rails is installed, you can create a new application. Navigate to the directory where you want to create your app and run:
     
     

arduino code

rails new myapp

• This command creates a new Rails application with SQLite3 as the default database in a directory named myapp.
     
     

8. Start the Rails Application

• Change into your application's directory:
     
     

bash code

cd myapp

• Start the Rails server:
     
     

code

rails server

• By default, the Rails server runs on port 3000. Access your application by navigating to http://your_vps_ip:3000 in a web browser.
