　　[root@localhost ~]#
　　2.  Create username and password for VNC Server
　　[root@localhost ~]# useradd lb
　　[root@localhost ~]# su lb
　　[lb@localhost root]$ cd ~
　　[lb@localhost ~]$ vncpasswd
　　Password:
　　Verify:
　　[lb@localhost .vnc]$
　　3. Configure VNC configuration for new user
　　编辑文件/etc/sysconfig/vncservers
　　注意：虽然root用户可以通过如下配置实现远程访问，但是不建议这样配置！
　　# 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:myusername”
　　# VNCSERVERARGS[2]=”-geometry 800×600 -nolisten tcp -localhost”
　　VNCSERVERS="1:root 2:lb"      #如果不配root，删掉字符串1:root
　　VNCSERVERARGS[1]="-geometry 800x600"     #如果不配root，删掉本行
　　VNCSERVERARGS[2]="-geometry 800x600"
　　[root@localhost ~]#
　　4. Start VNC Server and configure VNC Server run when server start up
　　[root@localhost ~]# chkconfig vncserver on
　　[root@localhost ~]# /etc/init.d/vncserver start
　　Starting VNC server: 2:kevin.ngo xauth: creating new authority file /home/kevin.ngo/.XauthorityNew ‘localhost.localdomain:2 (kevin.ngo)’ desktop is localhost.localdomain:2Creating default startup script /home/kevin.ngo/.vnc/xstartup
　　Starting applications specified in /home/kevin.ngo/.vnc/xstartup
　　Log file is /home/kevin.ngo/.vnc/localhost.localdomain:2.log[ OK ]
　　[root@localhost ~]#
　　5. Disable iptables on Centos 6.4
　　这一步非常重要
　　[root@localhost ~]# /etc/init.d/iptables stop
　　iptables: Flushing firewall rules: [ OK ]
　　iptables: Setting chains to policy ACCEPT: filter [ OK ]
　　iptables: Unloading modules: [ OK ]
　　[root@localhost ~]# chkconfig iptables off
　　[root@localhost ~]#
　　7. Use VNC Viewer and connect to VNC Server (Centos 6.8) with user lb
