官方的解释：

Based on the work ofFreeRDPandrdesktop, xrdp uses the remote desktop protocol to present a GUI to the user.

The goal of this project is to provide a fully functional Linux terminal server, capable of accepting connections from rdesktop, freerdp, and Microsoft‘s own terminal server / remote desktop clients.

Unlike Windows NT/2000/2003/2008/2012 server, xrdp will not display a Windows desktop but an X window desktop to the user.

Xrdp uses Xvnc or X11rdp to manage the X session. To learn about how xrdp currently works, clickhereandhere.

优点：不用装客户端工具，windows自带的就可以，较vnc安全性高！

1.安装linux 桌面环境，如果本身已经是图形界面，跳过这步即可！

确认以下组件被安装：

yum gruopinstall "Desktop" "Desktop Platform" " X window system"

安装完成，启动桌面系统。

init 5

确认图形界面已经启动：

runlevel

2.安装xrdp

用yum安装

yum install -y xrdp tigervnc-server

启动xrdp

/etc/init.d/xrdp start

确认xrdp跟vncserver都已经启动：

netstat -tlnp

防火墙中放开3389端口的访问！

3.从windows客户端连接linux服务器IP

开始菜单-->运行--> mstsc

输入用户名密码，回车，登陆成功！！！
