vncserver的详细配置

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
# http://www.uk.research.att.com/archive/vnc/sshvnc.html>;.

# 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
