Ruby on Rails, also known as Rails, is a powerful web development framework written in Ruby. It allows developers to build high-performing web applications quickly and efficiently. In this guide, we will walk you through the steps to install Ruby on Rails on Ubuntu 20.04 LTS. Whether you’re using a or another hosting solution, Rails provides a great foundation for building dynamic web apps.<\/p>\n
Before starting, ensure you have the following:<\/p>\n
Start by updating your system to ensure all packages are up to date. Run the following commands:<\/p>\n
sudo apt update && sudo apt upgrade -y<\/code><\/pre>\nStep 2: Install Ruby<\/h2>\n
Ruby on Rails is built on Ruby, so the first step is to install Ruby. You can install it using the package manager:<\/p>\n
sudo apt install ruby-full -y<\/code><\/pre>\nOnce installed, verify the Ruby version by running:<\/p>\n
ruby -v<\/code><\/pre>\nThis command should display the Ruby version, confirming that Ruby is installed.<\/p>\n
Step 3: Install Node.js and Yarn<\/h2>\n
Rails requires a JavaScript runtime to work properly, so you will need to install Node.js. You can also install Yarn, a JavaScript package manager, which is often used with Rails projects:<\/p>\n
sudo apt install nodejs\r\nsudo apt install yarn -y<\/code><\/pre>\nStep 4: Install Rails<\/h2>\n
Next, install Rails using the RubyGems package manager. Run the following command to install Rails:<\/p>\n
sudo gem install rails<\/code><\/pre>\nOnce the installation is complete, verify the Rails version by running:<\/p>\n
rails -v<\/code><\/pre>\nThis will display the installed Rails version.<\/p>\n
Step 5: Install a Database (Optional)<\/h2>\n
Ruby on Rails supports several databases, but the most common choice is PostgreSQL or MySQL. You can install PostgreSQL by running:<\/p>\n
sudo apt install postgresql postgresql-contrib libpq-dev -y<\/code><\/pre>\nAlternatively, for MySQL, run:<\/p>\n
sudo apt install mysql-server mysql-client libmysqlclient-dev -y<\/code><\/pre>\nStep 6: Create a New Rails Project<\/h2>\n
Now that Ruby, Rails, and the database are installed, you can create a new Rails project. Navigate to the directory where you want to store your project and run:<\/p>\n
rails new myapp -d postgresql<\/code><\/pre>\nReplace myapp<\/code> with your project name, and if you are using MySQL, replace -d postgresql<\/code> with -d mysql<\/code>.<\/p>\nStep 7: Set Up the Database<\/h2>\n
If you are using PostgreSQL, you will need to create a database user. Log in to PostgreSQL:<\/p>\n
sudo -u postgres psql<\/code><\/pre>\nCreate a new user with a password:<\/p>\n
CREATE ROLE myuser WITH LOGIN PASSWORD 'mypassword';<\/code><\/pre>\nThen, grant the necessary permissions and exit:<\/p>\n
ALTER ROLE myuser CREATEDB;\r\n\\q<\/code><\/pre>\nUpdate the database configuration file config\/database.yml<\/code> in your Rails project directory to match your database settings, then set up the database:<\/p>\nrails db:create<\/code><\/pre>\nStep 8: Start the Rails Server<\/h2>\n
To test that everything is working, start the Rails development server:<\/p>\n
rails server<\/code><\/pre>\nBy default, the server will run on port 3000. Open your web browser and navigate to http:\/\/your-server-ip:3000<\/code> to see the Rails welcome page.<\/p>\nConclusion<\/h2>\n
By following these steps, you have successfully installed Ruby on Rails on Ubuntu 20.04 LTS. Whether you\u2019re developing applications on a , Microsoft SQL VPS Windows<\/a>, or any Windows VPSVirtual Private Server Hosting<\/a> environment, Rails provides a robust platform for building scalable web applications.<\/p>\n
