RHEL 7.x - XRDP Installation and Configuration

※ If access to the RHEL Repository is not possible due to subscription termination, etc., the setup can be completed using an installation DVD or ISO file. In this case, refer to the How to register a DVD or ISO file OS installation to the Repository.

By default you can only create one session per user if the color values (Color Depth, BitPerPixel) are the same. If you use Xvnc and Xorg separately, you can use two sessions. To gain access to more sessions, you will need to change xrdp's session allocation policy. For a detailed explanation, see  RHEL 7.x - XRDP Enabling Multiple Sessions and Pause/Resume.

XRDP installation

$ sudo yum install epel-release
$ sudo yum install xrdp

# If you want to automatically start the xrdp service at system startup
$ sudo systemctl enable xrdp

Xorg Module Installation and Configuration

• Installation

  $ sudo yum install xorgxrdp

• Configuration
  Uncomment (#) the [Xorg] area of /etc/xrdp.ini.

  $ sudo vi /etc/xrdp.ini

Xvnc Installation and Configuration

• Installation
  If you don't have Xvnc, install a VNC server using the following command:

  $ sudo yum install tigervnc-server
  $ #or
  $ sudo yum install tigervnc-server-minimal

• Configuration
  If you want to install and use the Xfce desktop, you need to change it to 24-bit since Xfce does not support the default 32-bit color depth. Remove # from '#xserverbpp=24' in /etc/xrdp/xrdp.ini so that the setting takes effect.

  $ sudo vi /etc/xrdp/xrdp.ini

  ...
  [Xvnc]
  name=Xvnc
  lib=libvnc.so
  username=ask
  password=ask
  ip=127.0.0.1
  port=-1
  xserverbpp=24
  #delay_ms=2000
  ...

  $ sudo systemctl restart xrdp
