Linux组件安装

1.安装X Window支持
yum groupinstall "X Window System"
2.安装gnome
yum groupinstall Desktop
3.修改启动级别使开机默认进入图形化界面
vi /etc/inittab
   将最后一行id:3:initdefault:中的3改为5.
4重启
    注意:重启前千万不要执行startx命令,因为此时gnome下的鼠标和键盘驱动还未加载,进入图形化界面键鼠无响应会造成假死。

安装vncserver服务端和客户端端
yum install tigervnc tigervnc-server -y b.
安装fontforge
yum install fontforge -y
安装桌面软件
yum groupinstall Desktop -y
安装KDE
yum groupinstall "KDE Desktop"。

添加vncserver服务启动参数

vi /etc/sysconfig/vncservers
VNCSERVERS="1:root"
VNCSERVERARGS[1]="-geometry 1024x768 -localhost
设置配置文件
vi .vnc/xstartup
# twm &
gnome-session & 设置为gnome-session桌面,如果在前面安装了kde桌面,设置为:startkde。
如果想开机启动可以设置
chkconfig vncserver on
service vncserver start|stop|restart

vncserver -kill :1
[root@sg146 ~]# netstat -tulnp
