Ubuntu14.04配置VNC服务

第一步：安装VNCserver

指令：sudo apt-get install vnc4server

第二步：开启vnc服务

指令:vncserver

这里需要输入vnc链接的密码

看到..desk is master：1 说明已经启动了vnc服务。启动vnc成功后，会在主目录下产生一个.vnc目录（~/.vnc/）。 这时候window通过vnc链接到linux时，桌面系统是doc。

第三步：修改~/.vnc/xstartup文件

该文件是配置vnc桌面系统类型。默认内容如下。

#!/bin/sh

# Uncomment the following two lines for normal desktop:
# unset SESSION_MANAGER
# exec /etc/X11/xinit/xinitrc

[ -x /etc/vnc/xstartup ] && exec /etc/vnc/xstartup
[ -r $HOME/.Xresources ] && xrdb $HOME/.Xresources
xsetroot -solid grey
vncconfig -iconic &
x-terminal-emulator -geometry 80x24+10+10 -ls -title "$VNCDESKTOP Desktop" &
x-window-manager &

我们需要将最后一行“x-window-manager &”改为我们自己的Ubuntu图形界面服务，那么改成什么呢？这就要看你Ubuntu是什么桌面环境了，Ubuntu有gnome、KDE、Unity等桌面环境。

查看ubuntu桌面环境指令：vim/usr/share/gnome-session/sessions/ubutu.session

如果是gnome桌面，最后一行改成gnome-session &；
如果是KDE桌面，最后一行改成startkde &；
如果是Unity桌面，桌面session的名称是ubuntu-2d，则将最后一行改为：

export STARTUP="/usr/bin/gnome-session --session=ubuntu-2d"
$STARTUP

第四步：如果原始linux系统没有配置桌面系统

(1)安装x－windows的基础
sudo apt-get install x-window-system-core（一般都已安装）
(2)安装登录管理器
sudo apt-get install gdm （还可以为kdm/xdm）
(3)安装Ubuntu的桌面
sudo apt-get install ubuntu-desktop

第五步：完美配置

修改vim ~/.vnc/xstartup中的内容如下
