首先安装桌面环境：
yum groupinstall -y"X Window System"Fonts yum install -y epel-release yum install -y gdm mate-desktop mate-control-center mate-terminal mate-settings-daemon caja caja-open-terminal mozo mate-themes mate-screensaver mate-backgrounds pluma unlink /etc/systemd/system/default.target ln -sf /lib/systemd/system/graphical.target /etc/systemd/system/default.target ll /etc/systemd/system/default.target reboot安装软件
yum install -y xrdp tigervnc-server systemctl enable xrdp systemctl start xrdp reboot使用windows rdp连接，连上马上断线，查看日志提示：

echo"mate-session">> ~/.xsession chmod +x ~/.session增加上面步骤后，连接正常了！
