I had created a demo web application by executing rails tickets and then i executed rails script/server to run it on localhost.

Initially i was able to execute the application in the browser by typing localhost:3000 in the address bar, but then I deleted the folder tickets from my hard disk.

Now again i created the same folder but when i try to run it using the same command rails script/server it says that

vverma@l-vverma:~/railsExp/tickets$ rails script/server 
      create  
File exists - script/server

I tried deleting the script/server file but i still couldn't run the localhost:3000 in the browser

Tried rails s as well, it gave the following output:- http://paste.ubuntu.com/1317610/

But still i was unable to run the app on 'localhost:3000'

What is the solution to this
