If you’re looking to Install Ruby on Rails on Debian 12, you’re in the right place! Ruby on Rails is a powerful framework for building web applications, and setting it up on Debian 12 is straightforward. Here’s how I did it: Step 1: Update Your System
Before installing anything, update your system to ensure all packages are up to date: bash Copy
sudo apt update && sudo apt upgrade -y
Step 2: Install Dependencies
Ruby on Rails requires several dependencies. Install them using: bash Copy
sudo apt install curl git build-essential libssl-dev libreadline-dev zlib1g-dev libsqlite3-dev
Step 3: Install Ruby Using rbenv
The default Ruby version on Debian 12 might be outdated, so we’ll use rbenv to install and manage Ruby versions:
Install rbenv and ruby-build:
bash
Copy curl -fsSL https://github.com/rbenv/rbenv-installer/raw/main/bin/rbenv-installer | bash Add rbenv to your shell:
Add the following lines to your ~/.bashrc file:
bash
Copy export PATH="$HOME/.rbenv/bin:$PATH"
eval "$(rbenv init -)" Then, reload your shell:
bash
Copy source ~/.bashrc Install Ruby:
Install the latest stable version of Ruby (e.g., Ruby 3.2.2):
bash
Copy rbenv install 3.2.2
rbenv global 3.2.2 Verify the installation:
bash
Copy ruby -v You should see the installed Ruby version.
Step 4: Install Rails
With Ruby installed, you can now install Rails: bash Copy
gem install rails
Verify the installation: bash Copy
rails -v
Step 5: Set Up a Database
Rails applications typically use a database. Install MySQL or PostgreSQL based on your preference. Option 1: Install MySQL bash Copy
sudo apt install mysql-server libmysqlclient-dev
Configure MySQL and create a database for your Rails app. Option 2: Install PostgreSQL bash Copy
sudo apt install postgresql postgresql-contrib libpq-dev
Set up a PostgreSQL user and database for your Rails app. Step 6: Create a New Rails Application
Now that everything is set up, create a new Rails application: bash Copy
rails new myapp -d mysql # Use postgresql if you installed PostgreSQL
cd myapp
Step 7: Configure the Database
Edit the config/database.yml file to match your database settings. For example, for MySQL: yaml Copy
default: &default adapter: mysql2 encoding: utf8mb4 pool: <%= ENV.fetch("RAILS_MAX_THREADS") { 5 } %> username: root password: yourpassword socket: /var/run/mysqld/mysqld.sock
Run the database setup: bash Copy
rails db:setup
Step 8: Start the Rails Server
Finally, start the Rails server: bash Copy
rails server
Visit http://localhost:3000 in your browser to see your Rails app in action! Troubleshooting Common Issues
Ruby Installation Fails:
Ensure all dependencies are installed and try again. Database Connection Issues:
Double-check your database.yml file and ensure the database service is running. Permission Errors:
Use sudo where necessary or adjust file permissions.
