Can't Start Rails Development,Cloud 9

Question

I've tried to kill my rails server using this article from cloud 9.

I'm using the gem thin and everytime I try to run cloud server command I recieve this error

rails s -b $IP -p $PORT
=> Booting Thin
=> Rails 4.2.6 application starting in development on http://0.0.0.0:8080
=> Run `rails server -h` for more startup options
=> Ctrl-C to shutdown server
Thin web server (v1.6.4 codename Gob Bluth)
Maximum connections set to 1024  
Listening on 0.0.0.0:8080, CTRL+C to stop
Exiting

This error says, 8080 port already in use, you may need to use different port for you application

Update:

Try to kill the existing process. Find port number using this command ps -ef | grep thin and then kill it kill -9 <port>. Try running your app now.

It seems the port 8080 is in use, to find the PID using the port, run :

netstat -tulpn | grep :8080

Then you can kill -9 <PID>
