1、首先要配置的是服务端

A 确认服务器端是否安装了vncserver

使用rpm –qa vnc命令如果收到如下信息说明已经安装了vncserver,

[root@localhost: ~]#rpm -qa |grep vnc

gtk-vnc-python-0.3.2-3.el5

vnc-server-4.1.2-14.el5

gtk-vnc-0.3.2-3.el5

vnc-4.1.2-14.el5

B从光盘找到安装包进行安装

首先将光盘挂载(也叫解压)到某个目录这里是在/var/ftp/pub/下面建立了rhel5-64目录

mount –o loop rhel-server-5.3-x86_64-dvd.iso

/var/ftp/pub/rhel5-64/

然后在/var/ftp/pub/rhel5-64/Server目录下找到 vnc-server-4.1.2-14.el5.x86_64.rpm安装包,使用rpm –ivh vnc-server-4.1.2-14.el5.x86_64.rpm命令直接安装;

C 接下来就是最重要的配置步骤了:

服务器端配置如下:

1)第一次启动vncserver

会提示输入密码:

管理员帐户:

[root@localhost /]# vncserver

You will require a password to access your desktops.

Password: 输入vnc 连接密码

Verify: 确认vnc密码

xauth: creating new authority file /root/.Xauthority

New 'localhost.localdomain:1 (root)' desktop is localhost.localdomain:1

Creating default startup script /root/.vnc/xstartup

Starting applications specified in /root/.vnc/xstartup

Log file is /root/.vnc/localhost.localdomain:1.log

普通用户:

[root@localhost /]#su huilin

[huilin@localhost /]$ vncserver

You will require a password to access your desktops.

Password: 输入vnc 连接密码

Verify: 确认vnc密码

xauth: creating new authority file /home/huilin/.Xauthority

New 'localhost.localdomain:2 (huilin)' desktop is localhost.localdomain:2

Creating default startup script /home/huilin/.vnc/xstartup

Starting applications specified in /home/huilin/.vnc/xstartup

Log file is /home/huilin/.vnc/localhost.localdomain:2.log

* 注意到每个用户都可以启动自己的 vncserver,每个用户可以启动多个 vncserver,

用ip加端口号 ip:1,ip:2,ip:3 来标识。vncserver的大部分配置文件及日志文件都在用户home目录下.vnc目录下

用户可以自定义启动号码如:

[huilin@localhost /]$ vncserver :2

A VNC server is already running as :2

2)配置vnc的配置文件xstartup文件

如果用的是gnome 桌面环境还需要修改

[root@localhost .vnc]# vi xstartup

#!/bin/sh

# Uncomment the following two lines for normal desktop:

# unset SESSION_MANAGER

将此行的注释去掉

# exec /etc/X11/xinit/xinitrc

将此行的注释去掉

[ -x /etc/vnc/xstartup ] && exec /etc/vnc/xstartup

[ -r $HOME/.Xresources ] && xrdb $HOME/.Xresources

xsetroot -solid grey

vncconfig -iconic &

xterm -geometry 80x24+10+10 -ls -title "$VNCDESKTOP Desktop" &

gnome-session gnome

添加连接时使用 gnome 桌面环境

twm &

3)在vncserver设置登录用户的信息

[root@localhost: ~]#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

# <URL:http://www.uk.research.att.com/archive/vnc/sshvnc.html&gt;.

# Use "-nolisten tcp" to prevent X connections to your VNC server via TCP.

# Use "-nohttpd" to prevent web-based VNC clients connecting.

# 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 2:demo"

此处添加用户

VNCSERVERARGS[2]="-geometry 800x600 -nolisten tcp -nohttpd -localhost"

#vncserver -geometry 800x600

设置vncserver的分辨率

#vncserver -geometry 640x480

设置vncserver的分辨率

#vncserver -depth 8

设置vncserver的色深

#vncserver -depth 16

设置vncserver的色深

4)客户端的连接

a、在linux下,运行vncviewer命令即可,服务器地址的写法形如192.168.3.119:1

b、在windows下,运行windows版本的vncviewer即可,用法与linux下相近。

c、用浏览器(平台无关),作为java applet来实现,以形如http://192.168.3.119:5801的方式来启动

(vnc 端口从5800 开始依次类推,一般会是5800,5900)

5)修改密码

运行vncpasswd即可

6)停止vncserver

#vncserver -kill :1

#vncserver -kill :2

注意到vncserver只能由启动它的用户来关闭,即时是root也不能关闭其它用户开启的vncserver,

除非用kill命令暴力杀死进程。

7)稳定性设置

vncserver默认在多个客户机连接同一个vncserver的显示端口时,vncserver端口旧连接,而为新连接服务,可通过-dontdisconnect拒绝新连接请求而保持旧的连接。

8)同一个显示器可以连接多个客户
