2. Run the following command:

   rails s  
   

3. By default, the server runs at http://localhost:3000.
   

Options You Can Use

Specify a Port: Use rails s -p 4000 to run the server on port 4000. Choose a Server: Use rails s -u puma to specify a server type (e.g., Puma or WEBrick). Set the Environment: Run rails s -e production to start the server in production mode.

Troubleshooting Tips

• If the server doesn’t start, check for port conflicts or missing dependencies.
• Restart the server after making changes to config files.
