Tmux is a "terminal multiplexer", it enables a number of terminals to be accessed and controlled from a single terminal.
    
If you use Debian/Ubuntu, you can just run apt-get install tmux, and voila. 
  
Since the title was about centos 7, then do the following step to install tmux.
  (1). tmux has a library dependency on libevent which, of course, isn’t installed by default. 
    $ wget https://github.com/downloads/libevent/libevent/libevent-2.0.21-stable.tar.gz
    $ tar xzvf libevent-2.0.21-stable.tar.gz
    $ cd libevent-2.0.21-stable
    $ ./configure && make

• OAuth Protocol: http://tools.ietf.org/html/rfc6749#section-1.2
• Omniauth: https://github.com/intridea/omniauth

Implement OAuth in your Rails application:

1. Create an app on github (make sure the callback url is http://localhost:3000/auth/github/callback)

2. Add an initializer, config/initializers/omniauth.rb
