Ubuntu下的xfce桌面系统安装与VNC远程连接

感谢微魔大佬大力滋磁，原文链接：https://www.vmvps.com/installing-vnc-and-xfce-desktop-to-ubuntu-tutorial.html

1.安装必要的软件

apt-get -y install ubuntu-desktop tightvncserver xfce4 xfce4-goodies

2.增加VNC用户及密码

adduser vnc
passwd vnc

为VNC设置Root权限（前提是以Root用户登录）

echo "vnc ALL=(ALL)       ALL" >> /etc/sudoers

3.设置vnc的VNC Server密码

su - vnc
vncpasswd
exit

4.把VNC作为系统服务

#!/bin/bash
PATH="$PATH:/usr/bin/"
export USER="vnc"
DISPLAY="1"
DEPTH="16"
GEOMETRY="1024x768"
OPTIONS="-depth ${DEPTH} -geometry ${GEOMETRY} :${DISPLAY}"
. /lib/lsb/init-functions
case "$1" in
start)
log_action_begin_msg "Starting vncserver for user '\${USER}' on localhost:${DISPLAY}"

su ${USER} -c "/usr/bin/vncserver ${OPTIONS}"

;;
stop)

log_action_begin_msg "Stoping vncserver for user '${USER}' on localhost:${DISPLAY}"

su ${USER} -c "/usr/bin/vncserver -kill : ${DISPLAY}"

;;
restart)

$0 stop

$0 start

;;

esac

exit 0

#!/bin/sh
xrdb $HOME/.Xresources
xsetroot -solid grey
startxfce4 &

更新文件权限，使得其他用户也能启动VNC服务

chown -R vnc. /home/vnc/.vnc && chmod +x /home/vnc/.vnc/xstartup
sed -i 's/allowed_users.*/allowed_users=anybody/g' /etc/X11/Xwrapper.config

使/etc/init.d/vncserver可运行并启动VNC Server:

chmod +x /etc/init.d/vncserver && service vncserver start

修改VNC为自动启动

update-rc.d vncserver defaults

5.使用TightVNC进行远程连接
