# 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:root"
VNCSERVERARGS[2]="-geometry 800x600 -nolisten tcp -localhost"
~
红色部分两行必须要打开注释启用。

VNCSERVERARGS不能与VNCSERVERS同一个端口。

修改vnc password：

[root@node1 sysconfig]# vncpasswd
Password:
Verify:
[root@node1 sysconfig]#
[root@node1 sysconfig]# cd ~

启动服务一次,生成 /root/.vnc/xstartup：

[root@node1 .vnc]#
[root@node1 .vnc]# vncserver
xauth: creating new authority file /root/.Xauthority
xauth: (stdin):1: bad display name "node1:1" in "add" command

New 'node1:1 (root)' desktop is node1:1

Creating default startup script. /root/.vnc/xstartup
Starting applications specified in /root/.vnc/xstartup
Log file is /root/.vnc/node1:1.log

[root@node1 .vnc]#

-rw------- 1 root root 8 Jul 23 22:37 passwd
-rwxr-xr-x 1 root root 654 Jul 23 22:38 xstartup

修改xstartup文件：

[root@node1 .vnc]# vi xstartup

#!/bin/sh

[ -r /etc/sysconfig/i18n ] && . /etc/sysconfig/i18n
export LANG
export SYSFONT
vncconfig -iconic &

if [ $OS = 'Linux' ]; then
case "$WINDOWMANAGER" in
    *gnome*)
      if [ -e /etc/SuSE-release ]; then
        PATH=$PATH:/opt/gnome/bin
        export PATH
      fi
      ;;

if [ -x /etc/X11/xinit/xinitrc ]; then

exec sh /etc/X11/xinit/xinitrc
fi
[ -r $HOME/.Xresources ] && xrdb $HOME/.Xresources
xsetroot -solid grey
xterm -geometry 80x24+10+10 -ls -title "$VNCDESKTOP Desktop" &
#twm &
gnome-session &
~

将默认的twm注释掉，添加gnome-session &项。

手工kill掉vncserver进程，再重启vncserver：

[root@node1 .vnc]# vncserver -list

TigerVNC server sessions:

X DISPLAY # PROCESS ID
:1 5599
[root@node1 .vnc]# vncserver -kill :1
Killing Xvnc process ID 5599
[root@node1 .vnc]#

[root@node1 ~]# service vncserver start 或者 vncserver start 或者 /etc/init.d/vncserver start
Starting VNC server: 2:root xauth: (stdin):1: bad display name "node1:2" in "add" command

New 'node1:2 (root)' desktop is node1:2

Starting applications specified in /root/.vnc/xstartup
Log file is /root/.vnc/node1:2.log

[ OK ]
[root@node1 ~]#
[root@node1 ~]# vncserver -list

TigerVNC server sessions:

X DISPLAY # PROCESS ID

启动client端：
