centos5 下用脚本安装oracle10g

下面是本人写的一个安装oracle10g的安装脚本，已经在CentOS5的各个版本上运行过，没
有问题
使用方法是：
1、把下面的脚本考到一个文件里面，在root用户下运行这个脚本
2、脚本的运行过程中会给出运行提示。如果内存及临时空间检测不满足条件，也没有大的
问题。如果提示需要的软件包没有安装则要手动安装啦（一般相应的系统盘里面就有）

3、脚本运行成功会会给出提示“Oracle install pre-setting finish,please run orac
le installer as user oracle”。本脚本会添加一个oracle的用户，名称是oracle,密码
：000000
4、注销root，登录oracle，然后终端输入:export LANG=en_US.UTF-8
5、运行oracle的安装文件./runInstaller
6、再往下就是GUI界面啦，基本没有大的问题
ps:
不足：
1、没有解决中文乱码的问题，oracle用户是英文界面。
2、依赖的软件包到底有哪些没有搞明白，下面给出来的是个极大集合（没有时间仔细研究
啊，希望高手指点啦）。
3、还有些小的问题.例如 export DISPLAY变量是否必要等。本脚本没有执行，但是我的使用中没有发现问题。

仅供参考。有什么bug，希望高手赐教。
