Install Rails
Now that the Ruby environment is set up, run the commands below to install Rails. Rails can be installed from Node.Js. Run the commands below to install the Node.js repository, then install the Node.js package. Now that Node.js is installed, run the commands below to install Rails.

[Y/n]: Y Disallow root login remotely? [Y/n]: Y Remove test database and access to it? [Y/n]: Y Reload privilege tables now? [Y/n]: Y
Now that MariaDB is installed, to test whether the database server was successfully installed, run the commands below. type the root password when prompted. If you see a similar screen as shown above, then the server was successfully installed. After that, Ruby and Rails should be installed and your environment ready for you to start building apps based on Ruby and Rails.
