What XRDP is and How to Install XRDP on CentOS 7
For the uninitiated, RDP stands for Remote Desktop Protocol. And just like the expanded form suggests, it’s a protocol for a machine to accept remote desktop connections from other machines. XRDP is a server for CentOS 7 that implements this protocol and allows you to use different types of software to connect with your CentOS 7 server.
Before we move on, though, let us answer a natural question: why do XRDP when we have SSH sessions? A very good question, except that SSH vs. RDP is not really a debate. While SSH is based on a text-driven environment, RDP is concerned with fully graphical (GUI-based) control of your CentOS 7 machine. That means you can launch programs, send email, even play games, just as if you were sitting right in front of your machine.
Installing XRDP on CentOS 7
The first step is to install the EPEL repository so that its packages can be included into your system packages:
# wget http://dl.fedoraproject.org/pub/epel/7/x86_64/e/epel-release-7-5.noarch.rpm
# rpm -ivh epel-release-7-5.noarch.rpm
Then you need to update the yum package manager:
# yum update
The next step is to actually install XRDP. You’ll also need the tigervnc-server package:
# yum -y install xrdp tigervnc-server
Once done, you need to start the XRDP service and set it up to auto-launch when the system starts:
# systemctl start xrdp.service
# systemctl enable xrdp.service
Finally, if you’re using a firewall, you’ll need to add an exception for the port 3389, which is what XRDP uses:
# firewall-cmd –permanent –zone=public –add-port=3389/tcp
# firewall-cmd –reload
And with that, you have XRDP up and running on your CentOS 7 machine.
