oracle cloud ubuntu系统安装远程桌面 注意

首先 系统更新 apt update && upgrade

然后创建root密码  sodu passwd root 设置两边密码

然后su 转换到root超级用户，然后再cd /root

然后再用screen -R guo 创建一个不断连可恢复桌面  screen -list

最大的问题在于 iptables 以及服务的端口开放！

ip  源 0.0.0.0/0

源端口3389   目标端口 （默认不填 全部）

默认gnome桌面 大概2.6G的大小apt install ubuntu-desktop

apt install xrdp

然后设置 ufw allow 3389 防火墙放行端口

sudo iptables -I INPUT -p tcp --dport 3389 -j ACCEPT

然后reboot重启

systemctl status xrdp

出现下面信息表示ok
