How to install tmux on centos 7

    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
    $ sudo make install
  (2). To get and build the latest from version control:
    $ git clone https://github.com/tmux/tmux.git
    $ cd tmux
    $ sh autogen.sh
    $ ./configure && make

Tips:

 (1). During the second step, if you encounter with "libevent not found” error"
 You should install the libevent development package, by running the following command.
    $ yum install libevent-devel

(2). If you run with "curses not found" error
  To compile the code you need the devel packages, run the following comamnd
  $ yum install ncurses-devel
  $ yum install glibc-static
