How to generate temparory URL with localtunnel in ubuntu

Temperory make url with LocalTunnal :

1.)   Install localtunnel using RubyGems. 

       $ sudo gem install localtunnel

2.)   Run your local web server on any port! Let's say you're running Apache on        port 8080.

3.)   Now run localtunnel passing it the port to share. The first time you run            localtunnel you have to point to a public SSH key.

       Here's an example:

       $ localtunnel -k ~/.ssh/id_rsa.pub 3000

       You should see something like this:

       Port 8080 is now publicly accessible from http://8bv2.localtunnel.com         ...

       So your localtunnel link is : 

         http://8bv2.localtunnel.com
