4. Configure VNC

[root@ www.linuxidc.com ~]# su -jackiebui

［jackiebui@tanvps ~］# vncpasswd

Password:******

verify:******

[jackiebui@tanvps ~]# ls .vnc/

5. Edit VNC configuration file

[root@ www.linuxidc.com ~]# 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=”1:jackiebui” //Uncomment 2 last lines, and edit your VNC user

VNCSERVERARGS［2］=”-geometry 800×600 -nolisten tcp -localhost” // Save and exit

Start VNC

[root@ www.linuxidc.com ~]# vncserver

[root@ www.linuxidc.com ~]# chkconfig vncserver on //Set to start at boot

The above is an introduction to the method of installing and setting up VNC in CentOS6.3. Before installing VNC, you need to install the GNOME and KDE desktop environments. After installing VNC, you need to configure it.
