Me: How to Install xrdp on CentOS 7 / RHEL 7

From http://www.itzgeek.com/how-tos/linux/centos-how-tos/install-xrdp-on-centos-7-rhel-7.html
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 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

Issue the following 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, 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.
