摘要: 1. 安裝vnc
rpm -ivh vnc-server-4.1.2-14.el5_3.1.i386.rpm
rpm -ivh vnc-4.1.2-14.el5_3.1.i386.rpm


3. 設置vnc server的訪問密碼
[ann@ecdev1 ~]# vncpasswd

3. 執行vncserver,第一次執行后會生產一些配置文件

4. 修改/home/ann/.vnc/xstart（如果無此文件，就運行vncserver）
#!/bin/sh
# Uncomment the following two lines for normal desktop:
unset SESSION_MANAGER
exec /etc/X11/xinit/xinitrc
