去check下os版本，都是centos 64位的：

CentOS release 6.4 (Final)

这个为什么会报错呢？
------解决思路----------------------
uname -a
如果是64位，会显示x86_64
装的系统是32位的，要用32位的版本的oracle软件来安装
------解决思路----------------------
In 64 bit Linux operating system, getconf pointing to wrong bit (32 bit POSIX on 64 bit OS). This may be because of 64 bit POSIX overwritten by the 32bit glibc, glibc-common installation.
可能是这个问题
ls -l /usr/libexec/getconf/default
看看结果
------解决思路----------------------
这里错了
cd /usr/libexec/getconf/
看看下面是不是有一个POSIX_V6_LP64_OFF64这样的文件
如果有的话
root用户下，执行
ln -s /usr/libexec/getconf/default /usr/libexec/getconf/POSIX_V6_LP64_OFF64
名称如果错了按实际的修改
然后再启动安装
------解决思路----------------------
把原链接删除或重命名，再执行
------解决思路----------------------
抱歉，ln语句顺序写错了
cp /usr/libexec/getconf/POSIX_V6_LP64_OFF64.bak20150205 /usr/libexec/getconf/POSIX_V6_LP64_OFF64
mv /usr/libexec/getconf/default /usr/libexec/getconf/default.bak
ln -s /usr/libexec/getconf/POSIX_V6_LP64_OFF64 /usr/libexec/getconf/default
