1、redhat Enterprise Linux 6.2 beta VNC安装经验VNC（Virtual Network Computing）是可操控远程的计算机的软件，任何人都可免费取得该软件,其官方网站为http:/ 主要由两个部分组成：VNC server及VNC viewer。用户需先将VNC server安装在被控端的计算机上后，才能在主控端执行VNC viewer控制被控端。在N年前，本人记得有支持LINUX的免费版，但现在一看，虽然也有免费的，但只能下载在WINDOWS上安装的EXE文件，只好到其它网站下载，都没有运行成功。不过从Linux 6.2 beta光盘的package目录
2、下发现有VNC的软件包，不管三七二十一安装再说，居然成功了。与VNC有关的包为：rootwen Packages# ls | grep vncgtk-vnc-0.3.10-3.el6.i686.rpmgtk-vnc-python-0.3.10-3.el6.i686.rpmlibvncserver-0.9.7-4.el6.i686.rpmtigervnc-1.0.90-0.15.20110314svn4359.el6_1.1.i686.rpmtigervnc-server-1.0.90-0.15.20110314svn4359.el6_1.1.i686.rpm1， 使用rpm ivh 分别将上面
3、的包进行安装2， 使用rpm qa | grep vnc进行确认是否安装成功gtk-vnc-0.3.10-3.el6.i686.rpmgtk-vnc-python-0.3.10-3.el6.i686.rpmlibvncserver-0.9.7-4.el6.i686.rpmtigervnc-1.0.90-0.15.20110314svn4359.el6_1.1.i686.rpmtigervnc-server-1.0.90-0.15.20110314svn4359.el6_1.1.i686.rpm3，运行vncserver设置密码rootwen Packages# vncserverYou wil
4、l require a password to access your desktops.Password:Verify:4，修改文件rootwen Packages# vi /root/.vnc/xstartup将最后一行注释，追加一行如下#twm &gnome-session &其中gnome-session是启动Gnome图形界面；startkde是启动KDE图形界面；twm是启动文本界面。三者选其一。 此时运行下面命令。将出现错误rootwen Packages# service vncserver start正在启动VNC服务：no displays configured 失败5，修
5、改vi /etc/sysconfig/vncserversrootwen Packages# vi /etc/sysconfig/vncservers将最后两行修改为# VNCSERVERS=2:myusername# VNCSERVERARGS2=-geometry 800x600 -nolisten tcp -localhostVNCSERVERS=1:root 2:wenVNCSERVERARGS2=-geometry 800x600 -nolisten tcp -localhost启动VNC有错误信息rootwen Packages# service vncserver start正在

11、n /home/wen/.vnc/xstartupLog file is /home/wen/.vnc/:2.log 确定启动成功但无法登录将VNCSERVERARGS2=-geometry 800x600 -alwaysshared -depth 24rootwen Packages# service vncserver restart两个都能登录查资料-alwaysshared代表允许多用户同时登录 -depth代为色深，参数有8,16,24,32。-geometry 指定显示桌面的分辨率。参照下面资料资料1补充多用户配置：1.创建用户：user01,user02，并设置密码. 2.开启u
12、ser01 桌面2，user02桌面3并修改各自家目录下的xstartup 3.配置/etc/sysconfig/vncservers, 内容格式如下：vi /etc/sysconfig/vncserversVNCSERVERS=1:root,2:user01,3:user02VNCSERVERARGS1=-geometry 1024x768VNCSERVERARGS2=-geometry 1024x768VNCSERVERARGS3=-geometry 1024x768资料2为xuhua和root打开vnc，设置分辨率为800x600，不允许http方式VNCSERVERS=1:xuhua 2:rootVNCSERVERARGS1=-geometry 800x600 -nohttpdVNCSERVERARGS2=-geometry 800x600 -nohttpd修改，但重启VNC时失败VNCSERVERARGS1=-geometry 800*600 -alwaysshared -depth 16 VNCSERVERARGS2=-geometry 800x600 -alwaysshared -depth 246，开机时启动通过图形方式处理，或用chkconfig vncserver on也行
