Answer 1

I think somehow your rails server is keep running after you close it. You can try as

ps aux | grep ruby

see pid and then kill that pid

kill -9 <pid>

Now you can restart your server using

rails s

Note: From next time onwards try using Ctrl D for terminating rails server. That might help

Answer 2

run it on other port:

rails s -p 3001

so it'll load on localhost:3001

or kill all ruby processes:

killall ruby

and then run rails s

Answer 3

I too faced the issue it all because of ruby instances are not properly terminated.We can terminate processes running in the background by pids.

lsof -wni tcp:3000

It displays all running pids of ruby.and terminate that pids.

kill -9 PID

Or use

killall ruby
