# How to install terminal server

sudo su -
sed -i -r -e '/10\.200/s/^[^#]/#/;' -e '/^\&/s/^/#/;' /etc/rsyslog.conf
systemctl restart rsyslog

# install epel

cd
wget http://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm
yum -y install epel-release-latest-7.noarch.rpm

# install xrdp
yum -y groupinstall xfce ; yum -y install xrdp tigervnc-server patch xfce4-whiskermenu-plugin ; yum -y remove gnome-session

# install fonts
yum -y install gnu-free-*-fonts open-sans-fonts libXfont xorg-x11-font*
