在centos5下安装配置VNC
今天在公司安装了一下vnc,晚上没事,就记录一下吧,要不下次安装就又得google了^_^VNC简介
不能免俗,简单说介绍下VNC吧。
VNC,全称为Virtual Network Computing,是一个桌面共享系统。它的功能,类似于windows中的远程桌面功能。VNC使用了RFB(Remote FrameBuffer,远程帧缓冲)协议来实现远程控制另外一台计算机。它把键盘、鼠标动作发送到远程计算机,并把远程计算机的屏幕发回到本地。
VNC技术与平台无关,VNC Viewer可以和VNC Server在不同的操作系统上。VNC几乎支持所有的操作系统,也支持Java,甚至可以通过支持Java的浏览器来访问VNC Server。多个VNC客户端可以同时连接到一个VNC Server上。
在centos5下安装配置VNC
1.检查VNC客户端和服务器端是否已经安装
执行如下命令:
![](http://images.csdn.net/syntaxhighlighting/OutliningIndicators/None.gif)
rpm -q vnc vnc-server
如果返回类似如下信息,
![](http://images.csdn.net/syntaxhighlighting/OutliningIndicators/None.gif)
package vnc is not installed
![](http://images.csdn.net/syntaxhighlighting/OutliningIndicators/None.gif)
vnc-server-4.0-8.1
则说明系统已经默认安装了vnc服务器端(一般来说,系统都默认安装了vnc server)。
2. 将用户名加入到配置文件中
使用如下命令编辑配置文件,添加帐户信息:
![](http://images.csdn.net/syntaxhighlighting/OutliningIndicators/None.gif)
vi /etc/sysconfig/vncservers
做如下修改(红色部分为添加的部分):

#
![](http://images.csdn.net/syntaxhighlighting/OutliningIndicators/None.gif)
# Uncomment the line below to start a VNC server on display :1
![](http://images.csdn.net/syntaxhighlighting/OutliningIndicators/None.gif)
# as my 'myusername' (adjust this to your own). You will also
![](http://images.csdn.net/syntaxhighlighting/OutliningIndicators/None.gif)
# need to set a VNC password; run 'man vncpasswd' to see how
![](http://images.csdn.net/syntaxhighlighting/OutliningIndicators/None.gif)
# to do that.
![](http://images.csdn.net/syntaxhighlighting/OutliningIndicators/None.gif)
#
![](http://images.csdn.net/syntaxhighlighting/OutliningIndicators/None.gif)
# DO NOT RUN THIS SERVICE if your local area network is
![](http://images.csdn.net/syntaxhighlighting/OutliningIndicators/None.gif)
# untrusted! For a secure way of using VNC, see
![](http://images.csdn.net/syntaxhighlighting/OutliningIndicators/None.gif)
# <URL:http://www.uk.research.att.com/vnc/sshvnc.html>.
![](http://images.csdn.net/syntaxhighlighting/OutliningIndicators/None.gif)
![](http://images.csdn.net/syntaxhighlighting/OutliningIndicators/None.gif)
# VNCSERVERS="1:myusername"
![](http://images.csdn.net/syntaxhighlighting/OutliningIndicators/None.gif)
![](http://images.csdn.net/syntaxhighlighting/OutliningIndicators/None.gif)
# VNCSERVERS="1:gavin 2:john" # use the method for more user
![](http://images.csdn.net/syntaxhighlighting/OutliningIndicators/None.gif)
VNCSERVERS="2:root"
![](http://images.csdn.net/syntaxhighlighting/OutliningIndicators/None.gif)
![](http://images.csdn.net/syntaxhighlighting/OutliningIndicators/None.gif)
# VNCSERVERARGS[1]="-geometry 800x600"
![](http://images.csdn.net/syntaxhighlighting/OutliningIndicators/None.gif)
VNCSERVERARGS[2]="-geometry 1024x768"
3.设置 root用户的密码
使用如下命令设置密码:
![](http://images.csdn.net/syntaxhighlighting/OutliningIndicators/None.gif)
vncpasswd
当提示Verify时,再次输入密码确认。
4.启动VNC服务
使用如下命令启动VNC SERVER
![](http://images.csdn.net/syntaxhighlighting/OutliningIndicators/None.gif)
sbin/service vncserver start
当显示如下信息时,表示启动成功:
![](http://images.csdn.net/syntaxhighlighting/OutliningIndicators/None.gif)
Starting VNC server: 2:root [ OK ]
5.修改VNC SERVER的窗口管理器
vnc server默认使用的窗口管理器是twn,这是一个非常简单的窗口管理器,我们可以改成常用的GNOME或者KDE。
先使用如下命令进入用户的home目录:
![](http://images.csdn.net/syntaxhighlighting/OutliningIndicators/None.gif)
cd ~/.vnc
编辑启动项:
![](http://images.csdn.net/syntaxhighlighting/OutliningIndicators/None.gif)
vi xstartup
按照如下方式修改启动项:
![](http://images.csdn.net/syntaxhighlighting/OutliningIndicators/None.gif)
#!/bin/sh
![](http://images.csdn.net/syntaxhighlighting/OutliningIndicators/None.gif)
![](http://images.csdn.net/syntaxhighlighting/OutliningIndicators/None.gif)
# Uncomment the following two lines for normal desktop:
![](http://images.csdn.net/syntaxhighlighting/OutliningIndicators/None.gif)
unset SESSION_MANAGER
![](http://images.csdn.net/syntaxhighlighting/OutliningIndicators/None.gif)
exec /etc/X11/xinit/xinitrc
![](http://images.csdn.net/syntaxhighlighting/OutliningIndicators/None.gif)
![](http://images.csdn.net/syntaxhighlighting/OutliningIndicators/None.gif)
[ -x /etc/vnc/xstartup ] && exec /etc/vnc/xstartup
![](http://images.csdn.net/syntaxhighlighting/OutliningIndicators/None.gif)
[ -r $HOME/.Xresources ] && xrdb $HOME/.Xresources
![](http://images.csdn.net/syntaxhighlighting/OutliningIndicators/None.gif)
xsetroot -solid grey
![](http://images.csdn.net/syntaxhighlighting/OutliningIndicators/None.gif)
vncconfig -iconic &
![](http://images.csdn.net/syntaxhighlighting/OutliningIndicators/None.gif)
xterm -geometry 80x24+10+10 -ls -title "$VNCDESKTOP Desktop" &
![](http://images.csdn.net/syntaxhighlighting/OutliningIndicators/None.gif)
gnome-session & #以GNOME作为VNC的窗口管理器
![](http://images.csdn.net/syntaxhighlighting/OutliningIndicators/None.gif)
#startkde & #kde desktop
![](http://images.csdn.net/syntaxhighlighting/OutliningIndicators/None.gif)
#twm & #注掉系统默认的窗口管理器
6.重启VNC SERVER
![](http://images.csdn.net/syntaxhighlighting/OutliningIndicators/None.gif)
/sbin/service vncserver restart
当系统提示如下信息时,表示重启成功:
![](http://images.csdn.net/syntaxhighlighting/OutliningIndicators/None.gif)
Shutting down VNC server: 2:root [ OK ]
![](http://images.csdn.net/syntaxhighlighting/OutliningIndicators/None.gif)
Starting VNC server: 2:root [ OK ]
windows登录到VNC SERVER
1.从IE登录
直接从IE浏览器中输入如下地址:
http://xxx.xxx.xxx.xxx:5802
输入密码即可使用。
2.从VNC view登录
在windows上安装vnc view,然后输入xxx.xxx.xxx.xxx:2,连接登录,输入密码即可。
备注:如果从vnc view登录时,提示connection refused(10061),则是因为linux防火墙的问题,登录centos系统,选择System-->Preferences-->Remote Desktop,勾选sharing中的两项,Security两项不勾,点击关闭,然后再重新用vnc view登录即可。
