Question

If I start mongrel the error will come. What can I do? Tell me another way to start Mongrel please...

$script/server mongrel

=> Booting Mongrel (use 'script/server webrick' to force WEBrick)
=> Rails 2.2.2 application starting on http://0.0.0.0:3000
=> Call with -d to detach
=> Ctrl-C to shutdown server
** Starting Mongrel listening at 0.0.0.0:3000

Answer 1

The error means you have an other server already running on the port 3000. Either quit that server or start Mongrel on another port.

$ script/server mongrel -p 3001

Answer 2

I had this experience that when I start mongrel server and use Ctrl-C to shut down the mongrel server in ubuntu, the server will not shut down, and I wont be able to start the mongrel server in the same port until some time(or perhaps till a system restart). So, do not exit terminal while running a mongrel server. When you have to shut down the mongrel server, use Ctrl-Alt-C in ubuntu.
