xrdp is an Open Source Remote desktop Protocol server, which allows you to RDP to your Linux server from Windows machine; it is capable of accepting connections from  rdesktop, freerdp, and remote desktop clients. This how to will help you to setup xrdp server on CentOS 7 / RHEL 7.

Prerequisites:

1. This was written when xrdp is available neither on CentOS repositories nor on EPEL repository, after a lot of Google search; i found desktop repository (http://li.nux.ro/) which was having xrdp for CentOS 7 / RHEL 7. We need to manually setup the repository on CentOS 7.
2. Don’t forget to install Gnome on CentOS 7

Automatic (recommended):

Install EPEL and nux Desktop repository rpms.
# rpm -Uvh https://dl.fedoraproject.org/pub/epel/7/x86_64/e/epel-release-7-5.noarch.rpm
# rpm -Uvh http://li.nux.ro/download/nux/dextop/el7/x86_64/nux-dextop-release-0-1.el7.nux.noarch.rpm

Manual:

Create a repository file.
# vi /etc/yum.repos.d/xrdp.repo
Place the following content. Once added, save and close the file.
[xrdp]
name=xrdp
baseurl=http://li.nux.ro/download/nux/dextop/el7/x86_64/
enabled=1
gpgcheck=0

Installation:

Issue the  following command to install xrdp
# yum -y install xrdp tigervnc-server
You will get the following output, make sure you are getting package from the newly created repository.

Installed:

Once it is installed, lets start the xrdp service.
# systemctl start xrdp.service
xrdp will listen on 3389, lets confirm this by issuing following command.
# netstat -antup | grep xrdp
tcp        0      0 0.0.0.0:3389            0.0.0.0:*               LISTEN      1508/xrdp
tcp        0      0 127.0.0.1:3350          0.0.0.0:*               LISTEN      1507/xrdp-sesman
By default, services wont auto start after system reboot. Issue the following command to enable the service at system start up.
# systemctl enable xrdp.service
Next is to create iptables rule to allow rdp connection from the external machines, following command will add the exception for rdp port (3389).
# firewall-cmd --permanent --zone=public --add-port=3389/tcp
# firewall-cmd --reload
Configure SELinux
# chcon --type=bin_t /usr/sbin/xrdp
# chcon --type=bin_t /usr/sbin/xrdp-sesman

Test:

Now take rdp from any windows machine using Remote Desktop Connection, enter ip address of Linux server in computer field and click on  connect
Note:Display settings of Remote desktop must be 24 bit
