1、redhat Enterprise Linux 6.2 beta VNC安裝經(jīng)驗(yàn)VNC（Virtual Network Computing）是可操控遠(yuǎn)程的計(jì)算機(jī)的軟件，任何人都可免費(fèi)取得該軟件,其官方網(wǎng)站為 主要由兩個(gè)部分組成：VNC server及VNC viewer。用戶需先將VNC server安裝在被控端的計(jì)算機(jī)上后，才能在主控端執(zhí)行VNC viewer控制被控端。在N年前，本人記得有支持LINUX的免費(fèi)版，但現(xiàn)在一看，雖然也有免費(fèi)的，但只能下載在WINDOWS上安裝的EXE文件，只好到其它網(wǎng)站下載，都沒有運(yùn)行成功。不過從Linux 6.2 beta光盤的package目錄下發(fā)現(xiàn)有VN

2、C的軟件包，不管三七二十一安裝再說，居然成功了。與VNC有關(guān)的包為：rootwen Packages# ls | grep vnc1， 使用rpm ivh 分別將上面的包進(jìn)行安裝2， 使用rpm qa | grep vnc進(jìn)行確認(rèn)是否安裝成功3，運(yùn)行vncserver設(shè)置密碼rootwen Packages# vncserverYou will require a password to access your desktops.Password:Verify:4，修改文件rootwen Packages# vi /root/.vnc/xstartup將最后一行注釋，追加一行如下#twm &a

3、mp;gnome-session &其中g(shù)nome-session是啟動(dòng)Gnome圖形界面；startkde是啟動(dòng)KDE圖形界面；twm是啟動(dòng)文本界面。三者選其一。 此時(shí)運(yùn)行下面命令。將出現(xiàn)錯(cuò)誤rootwen Packages# service vncserver start正在啟動(dòng)VNC服務(wù)：no displays configured 失敗5，修改vi /etc/sysconfig/vncserversrootwen Packages# vi /etc/sysconfig/vncservers將最后兩行修改為# VNCSERVERS="2:myusername"
