什么是tmux
tmux 是一个多通道终端。 最大的好处是：
- 可以避免终端中断带来的session中断
当运行tmux时，实际上会运行一个tmux service，保持session的运行。
tmux的提出的概念是 tmux / sessions * / windows + / panes + tmux可以管理多个sessions。 一个session有多个windows。 一个windows有多个panes。 每个pane是一个终端。
安装
yum -y install tmux
tmux prefix
prefix 是一个重要的概念。它是一个tmux的快捷键，默认是[ctrl + b]。 比如，退出tmux的命令是
tmux -detach等价于 [ctrl + b, d]
配置文件
~/.tmux.conf
