Address already in use - bind(2) for 178.62.19.65:80 (Errno::EADDRINUSE), how do I restart unicorn on port80

I have done few alterations to my database but it is not reflected when I restart rails server. I use 

 sudo service unicorn stop

and 

 sudo service unicorn start

Unicorn starts but when I run the following line of code, 

 root@moneytree:/home/zhall/zoulfia# rails s -p80 -e 
     production --   binding=moneytree.space

I get:

  => Booting Unicorn
   => Rails 4.2.0 application starting in production     
  on http://moneytree.space:80
  => Run `rails server -h` for more startup options
  => Ctrl-C to shutdown server 
  E, [2015-07-11T09:34:29.299617 #30491] ERROR --

  Exiting

  Address already in use - bind(2) for 178.62.19.65:80 (Errno::EADDRINUSE)

Why doesn't unicorn port80 get refreshed? Any help would be very, very welcome.

All I needed to do is to set the 'preload_app' to 'false' in my /etc/unicorn.config file. After that changes to application code were reflected when unicorn were restarted.

There's a program already running on port 80. Check with netstat netstat -ntl | grep -w 80. If you see a line with LISTEN then the port is already being used. Alternatively you could run rails on a different port as follows: rails s -p 8080 -e production
