安裝 XRDP

Step 1. Install EPEL and nux Desktop repository rpms by automatic. (recommended)
# yum localinstall http://li.nux.ro/download/nux/dextop/el7/x86_64/nux-dextop-release-0-1.el7.nux.noarch.rpm

Step 2. The following command to install xrdp, and you will get the following output, make sure you are getting package from the newly created repository.
# yum -y install xrdp tigervnc-server

Step 3. Once it is installed, lets start the xrdp service.
# systemctl start xrdp.service

Step 4. The xrdp will listen on 3389, lets confirm this by issuing following command.
# netstat -antup | grep xrdp

Step 5. 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

Step 6. Next is to create iptables rule to allow rdp connection from the external machines, following command will add the exception for xrdp port (3389).(如果步驟 6 沒成功，先重開機再試)
# firewall-cmd --permanent --zone=public --add-port=3389/tcp
# firewall-cmd --reload
