安装一个RH9搞学习^0^
公司要搞个Linux项目，要使用Qt图形编程。我不得不又重新拾起遗忘已久Linux。其实，原来只是图新鲜瞎琢磨，没有怎么系统的学习。废话少说，开始吧……我在虚拟机VM上安装了一个RH9，安装时只选择了XServer没有选择Gnome和KDE，选择了开发工具，再就没有选择其他软件包了。就这样也用了1G多。
开机从加电到出现提示符用了1分20秒左右，我觉得有点慢。查看一下开机启动了哪些服务：

查看了网上的资料（http://www.ccw.com.cn/server/yyjq/htm2005/20050914_14ND5.htm）后，我删除了一些服务，启动时间缩短为1分钟。
