	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

	# key commands
