问题
I don't know what I did. I think I updated my Ruby on Rails. After updating it, I always get error when running $rails server.
output is
ruby-1.9.2-p290/lib/ruby/1.9.1/webrick/utils.rb:73:in `initialize': Address already in use - bind(2) (Errno::EADDRINUSE)
I would restart the console and run rails server and it would work fine for a couple of minutes but then it would stop responding and if I restart rails server it would give me that error again. I tried running on different port (rails s -p 9191) and it gives me the same problem.
Any Ideas what I did wrong? Thnx guys
回答1:
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

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

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
