linux安装桌面环境（GNOME）VNC连接Linux

1.安装Gnome桌面

这里是使用的脚本安装。代码如下：  加附件

#!/bin/sh

#This script is FREE and written by www.vpsyou.com  

# install yum-fastestmirror  

yum -y install yum-fastestmirror  

# Create new soft download dir  

mkdir -p /backup/www.vpsyou.com;  

cd /backup/www.vpsyou.com;  

# Install x window softwares  

yum -y groupinstall "X Window System"  

yum -y  groupinstall "GNOME Desktop Environment"  

yum -y  install nc expect freenx  

yum -y  groupinstall chinese-support  

#install firefox  

yum -y install firefox  

# Copy client.id_dsa.key to /backup/www.vpsyou.com/  

# Please use FTP or winscp to download it  

cp /etc/nxserver/client.id_dsa.key /backup/www.vpsyou.com/  

chmod 755 /backup/www.vpsyou.com/client.id_dsa.key  

# iptables  

iptables -A INPUT -i lo -s 127.0.0.1 -j ACCEPT  

iptables -A INPUT -p tcp --dport 22 -j ACCEPT  

iptables -A OUTPUT -p udp --sport 22 -j ACCEPT  

iptables -A INPUT -p tcp --dport 5000 -j ACCEPT  

iptables -A OUTPUT -p udp --sport 5000 -j ACCEPT  

sed -i 's#SELINUX=enforcing#SELINUX=disabled'# /etc/selinux/config  

echo "==========================="  

    get_char()  

    {  

    SAVEDSTTY=`stty -g`  

    stty -echo  

    stty cbreak  

    dd if=/dev/tty bs=1 count=1 2> /dev/null  

    stty -raw  

    stty echo  

    stty $SAVEDSTTY  

    }  

    echo ""  

    echo "======= Download FreeNX Windows software  : ======= "  

        echo ""  

        echo "http://www.nomachine.com/download-client-windows.php"  

        echo ""  

        echo ""  

        echo "======= How to use FreeNX connect to your Linux X Window System: ======= "  

        echo "http://www.vpsyou.com/centos-install-desktop/"  

        echo ""  

    echo "Install X Window System Successful,Press any key to end..."  

    char=`get_char`  

2.安装VNC

yum install vnc-server vnc* -y

3、配置和启动VNC

vi /etc/sysconfig/vncservers

4.为远程用户设置密码

vncserver:1

或者

vncpasswd      或者 vncpasswd root     ##默认是root

5.修改远程桌面显示配置文件   目录在/root/.vnc

vi xstartup    ##这个文件附件里面有

内容如下：

#!/bin/sh

# Add the following line to ensure you always have an xterm available.

# 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 &

xterm -geometry 80x24+10+10 -ls -title "$VNCDESKTOP Desktop" &

#twm &

gnome-session &

6、开启VNC服务

/sbin/service vncserver start

/sbin/service vncserver stop

sbin/service vncserver restart

service vncserver restart

7.查看VNC监听的哪些端口

netstat -luntp | grep "vnc"

7.修改防火墙策略

vi /etc/sysconfig/iptables

-A RH-Firewall-1-INPUT -p tcp -m tcp --dport 5801 -j ACCEPT

-A RH-Firewall-1-INPUT -p tcp -m tcp --dport 5901 -j ACCEPT

-A RH-Firewall-1-INPUT -p tcp -m tcp --dport 6001 -j ACCEPT

8.重启防火墙 

service iptables restart

9.开机启动VNC

vi /etc/rc.d/rc.local

/etc/init.d/vncserver start   --新增一行

###########想杀掉已启动的VNC客户端如下：

vncserver -kill :1

vncserver -kill :2

10 Windows登录测试

VNC Viewer登录测试

也可以在网页登录测试 必须支持Java
