Xrdp - 通过Windows的RDP连接Linux远程桌面（Ubuntu/CentOS/Redhat 7）

您多久访问一次Linux桌面？您使用什么工具来访问远程桌面？

Xrdp是一个开源工具，允许用户通过Windows RDP访问Linux远程桌面。除了Windows RDP之外，xrdp工具还接受来自其他RDP客户端的连接，如FreeRDP，rdesktop和NeutrinoRDP。 Xrdp现在支持TLS安全层。

Xrdp要求

xrdp和xorgxrdp包
监听3389/tcp。确保您的防火墙接受连接

在本文中，我将展示如何使用Xrdp工具从Windows机器远程连接到Ubuntu桌面。

1）在Linux上安装

在Ubuntu 18.04/Ubuntu 18.10上

首先，您需要在Ubuntu上安装Xrdp

apt install xrdp

您必须配置polkit规则以避免在Windows上的xrdp登录屏幕上输入用户名和密码后进行身份验证弹出窗口

linuxidc@linuxidc:~$ sudo nano /etc/polkit-1/localauthority.conf.d/02-allow-colord.conf

polkit.addRule(function(action, subject) {
if ((action.id == “org.freedesktop.color-manager.create-device” || action.id == “org.freedesktop.color-manager.create-profile” || action.id == “org.freedesktop.color-manager.delete-device” || action.id == “org.freedesktop.color-manager.delete-profile” || action.id == “org.freedesktop.color-manager.modify-device” || action.id == “org.freedesktop.color-manager.modify-profile”) && subject.isInGroup(“{group}”))
{
return polkit.Result.YES;
}
});

重启xrdp服务

linuxidc@linuxidc:~$ sudo systemctl restart xrdp

然后确保该服务正在运行

linuxidc@linuxidc:~$ systemctl status xrdp

现在确保在系统启动时自动启动服务

linuxidc@linuxidc:~$ systemctl enable xrdp
Synchronizing state of xrdp.service with SysV service script with /lib/systemd/systemd-sysv-install.

现在您需要检查您的IP地址，因为您将需要它来进行连接

linuxidc@linuxidc:~$ ip add
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000
link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00

2: ens33: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc fq_codel state UP group default qlen 1000

inet6 fe80::3f83:c7da:950a:e08/64 scope link noprefixroute
valid_lft forever preferred_lft forever

我的IP地址是192.168.182.146。所以请记住。

Xrdp使用端口3389，所以一定要打开它。默认情况下禁用UFW，因此您需要启用防火墙并为xrdp创建规则

linuxidc@linuxidc:~$ sudo ufw enable
[sudo] linuxidc 的密码：
在系统启动时启用和激活防火墙
linuxidc@linuxidc:~$ sudo ufw allow 3389/tcp
规则已添加
规则已添加 (v6)

如果这时候出现所说的Ubuntu安中装的xrdp，桌面共享设置为允许，虚拟机设置的是桥接，虚拟机内外可以互相ping 通；
在Windows下用 mstsc 连接Ubuntu桌面，跳出账号密码页面，登录后自动退出（闪退）的解决方法：

sudo apt-get install xfce4
echo xfce4-session > ~/.xsession
touch .session
sudo vim /etc/xrdp/startwm.sh
在. /etc/X11/Xsession前面加
xfce4-session

然后重启 sudo service xrdp restart。

现在，您可以在Windows端继续配置。

在CentOS/RedHat 7上

确保之前安装了Epel存储库

# rpm -Uvh https://dl.Fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm

Xrdp - 通过Windows的RDP连接Ubuntu Linux远程桌面

现在安装xrdp包

# yum update && yum -y install xrdp tigervnc-server

在防火墙中添加规则。 CentOS/RedHat不是ufw，而是firewalld来配置

[root@localhost ~]# firewall-cmd --permanent --zone=public --add-port=3389/tcp
success

然后重新加载防火墙
[root@localhost ~]# firewall-cmd --reload
success

现在启用并重新启动xrdp服务
[root@localhost ~]# systemctl enable xrdp && systemctl restart xrdp
Created symlink from /etc/systemd/system/multi-user.target.wants/xrdp.service to /usr/lib/systemd/system/xrdp.service.

检查您的IP地址以获取Windows上的远程连接
