# permissive - SELinux prints warnings instead of enforcing.
# disabled - No SELinux policy is loaded.
SELINUX=disabled

# targeted - Targeted processes are protected,
# mls - Multi Level Security protection.

Install vncserver
yum install *vnc*
Configure it.
Uncomment the highlighted section & also provide a valid username.
vi /etc/sysconfig/vncservers
# The VNCSERVERS variable is a list of display:user pairs.
#
# Uncomment the lines below to start a VNC server on display :2
# as my 'myusername' (adjust this to your own). You will also
# need to set a VNC password; run 'man vncpasswd' to see how
# to do that.
#
# DO NOT RUN THIS SERVICE if your local area network is
# untrusted! For a secure way of using VNC, see this URL:
# http://kbase.redhat.com/faq/docs/DOC-7028
# Use "-nolisten tcp" to prevent X connections to your VNC server via TCP.
# Use "-localhost" to prevent remote VNC clients connecting except when
# doing so through a secure tunnel. See the "-via" option in the
# `man vncviewer' manual page.
VNCSERVERS="2:root"
VNCSERVERARGS[2]="-geometry 800x600 -nolisten tcp -localhost"
Provide password for vncserver.
