When you’re developing a Ruby on Rails application or working with Sinatra, it’s essential to know how to start and stop your server. In this blog post, we’ll discuss how to stop a Ruby server, allowing you to perform tasks such as updating your code, fixing bugs, or simply taking a break.
Stopping a Ruby on Rails Server
If you’re using Ruby on Rails, the chances are that you’re running your server using the rails server command. To stop the server, follow these steps:
-
Locate your server’s process ID (PID). You can find the PID in the console output when you started the server. It usually appears in a line like this:
[pid 12345] * Listening on tcp://localhost:3000[/pid]
In this example, the PID is 12345.
-
To stop the server, you’ll need to issue a kill command to terminate the server process. Open a new terminal window and run the following command (replace your_pid with your actual PID):
kill your_pid
Alternatively, you can stop the server by pressing Ctrl + C in the terminal window where the server is running. This will send an interrupt signal to the server, causing it to shut down gracefully.
Stopping a Sinatra Server
If you’re using Sinatra, you likely started your server using the ruby app.rb command. Stopping a Sinatra server is similar to stopping a Rails server:
-
Locate the server’s process ID (PID) in the console output when you started the server. It will appear as a line similar to this (the PID is 12345 in this example):
[pid 12345] * Listening on tcp://localhost:4567[/pid]
-
Open a new terminal window and issue the kill command to stop the server (replace your_pid with your actual PID):
kill your_pid
Alternatively, you can stop the server by pressing Ctrl + C in the terminal window where the server is running.
Conclusion
Stopping a Ruby server is a simple process once you know the server’s process ID (PID) and are familiar with the kill command. Now you can easily stop your server whenever necessary, whether you’re working with Ruby on Rails or Sinatra.
