Ruby on Rails, commonly referred to as Rails, is a popular open-source web application framework written in Ruby, a dynamic, object-oriented programming language. Rails follows the Model-View-Controller (MVC) architectural pattern, which separates an application into three main logical components: models for handling data and business logic, views for rendering user interfaces, and controllers for handling user requests and coordinating interactions between the model and view.

In this tutorial, we will show you how to install Ruby on Rails on Ubuntu 22.04.

## Step 1 – Install Required Dependencies

First, we need to install the necessary dependencies. Open your terminal and run the following command:

```bash
apt install -y git curl libssl-dev libreadline-dev zlib1g-dev autoconf bison build-essential libyaml-dev libreadline-dev libncurses5-dev libffi-dev libgdbm-dev
```

## Step 2 – Install rbenv

Rbenv is a lightweight Ruby version management tool that allows you to easily install and switch between different versions of Ruby. Install rbenv by running the following command:

```bash
curl -fsSL https://github.com/rbenv/rbenv-installer/raw/HEAD/bin/rbenv-installer | bash
```

Next, add rbenv to your PATH and initialize it by adding the following lines to your ~/.bashrc file:

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

## Step 3 – Install Ruby

Now that rbenv is set up, we can install the desired version of Ruby. In this example, we’ll install Ruby version 3.2.0:

```bash
rbenv install 3.2.0
```

Make Ruby available globally.

```bash
rbenv global 3.2.0
```

Verify that Ruby has been successfully installed by running:

```bash
ruby -v
```

You should see output similar to:

```bash
ruby 3.2.0 (2022-12-25 revision a528908271) [x86_64-linux]
```

## Step 4 – Install Node.js

Rails requires a JavaScript runtime for compiling assets. Install Node.js using the following commands:

```bash
curl -fsSL https://deb.nodesource.com/setup_lts.x | sudo -E bash -
apt-get install -y nodejs
```

## Step 5 – Update RubyGems

Ensure that RubyGems, the package manager for Ruby, is up to date:

```bash
gem update --system
```

Check the version of RubyGems:

```bash
gem -v
```

You should see the version number, for example:

```bash
3.5.11
```

## Step 6 – Install Rails

Finally, let’s install Ruby on Rails using the following command:

```bash
gem install rails -v 7.0.4
```

Verify that Rails has been installed correctly:

```bash
rails -v
```

You should see output similar to:

```bash
Rails 7.0.4
```

## Step 7 – Create a New Rails Application

You’re now ready to create your first Rails application. Navigate to the directory where you want to create the application and run:

```bash
rails new my_app
```

Replace my_app with the desired name for your application.

Navigate into your newly created Rails application directory:

```bash
cd my_app
```

Start the Rails server:

```bash
rails server --binding=0.0.0.0
```

You should see the following output indicating that the server is running:

```bash
=> Booting Puma
=> Rails 7.1.3.4 application starting in development 
=> Run `bin/rails server --help` for more startup options
Puma starting in single mode...
* Puma version: 6.4.2 (ruby 3.2.0-p0) ("The Eagle of Durango")
*  Min threads: 5
*  Max threads: 5
*  Environment: development
*          PID: 50188
* Listening on http://0.0.0.0:3000
Use Ctrl-C to stop
```

## Step 8 – Access Rails Application

Now, open your web browser and access your Rails application using the URL **http://your-server-ip:3000.**
