通过基本安装，按照：
dnf install -y xrdp
openssl req -x509 -newkey rsa:2048 -nodes -keyout key.pem -out cert.pem -days 365
mv cert.pem /etc/xrdp/
mv key.pem /etc/xrdp/
systemctl start xrdp
systemctl status xrdp
systemctl enable xrdp
firewall-cmd --add-port=3389/tcp --permanent
firewall-cmd --reload
尝试连接时我收到以下信息：
...

您需要在服务器上安装图形环境。如果 dnf 不起作用，请替换dnf为。yum
# dnf install @kde-desktop [KDE Desktop]
# dnf install @xfce-desktop [XFCE Desktop]
# dnf install @mate-desktop [Mate Desktop]
