Prerequisites
1. This post was written when xrdp is available neither on CentOS repositories nor 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
3. Install and configure EPEL repository.
rpm -Uvh https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm
4. Add nux repository.
Automatic (recommended)
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
Install xrdp on CentOS 7
Use YUM command to install xrdp.
yum -y install xrdp tigervnc-server
You will get the following output. Make sure you are getting the package from the newly created repository.

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
Output:
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. The 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 Remote Connectivity
Now take RDP from any windows machine using Remote Desktop Connection, enter the ip address of Linux server in the computer field and click on connect.
You would be asked to enter the user name and password. You can either use root or any user that you have it on the system. Make sure you use module “sesman-Xvnc”.
If you click ok, you will see the processing. In less than a half min, you will get a desktop.
