GateOne介绍

GateOne 是一款使用 HTML5 技术编写的网页版 SSH 终端模拟器。就是类似于Windows上远程ssh工具，例如Xshell等。
亮点有：
• 基于现代的 HTML5 技术，无需任何浏览器插件。
• 支持多个 SSH 进程。
• 可以嵌入到其他任意应用程序中。
• 支持使用 JavaScript，Python 甚至纯 CSS 编写的插件。
• 支持 SSH 进程副本，打开多个进程而无需重复输入密码。
• 支持各种服务器端的日志功能，支持 Keberos-based 单点登录甚至活动目录。
以上参考：https://linuxtoy.org/archives/gateone.html 可以看到外网的介绍视屏。
官网上介绍说在CentOS下安装GateOne的先决条件是：
（1） Python 版本为2.6+和3.2+
（2） Tornado Framework 框架2.2+
（3） 如果Python是2.6版本的需要安装ordereddict module
（4） tornado kerberos等模块

安装过程

（1） 下载必要的源

启动出现了问题，找了一下，原来是tornado版本不对

[root@localhost gateone]# python -c "import tornado; print(tornado.version)"
4.4.1

要求是2.4左右的才能运行GateOne的server
