1. 上Oracle的网站上下载最新的Oracle 11.2安装包，因为CentOS6装的是x86_64的，所以，Oracle也选择Linux x86_64的安装包。下载下来是2个zip文件包
2。安装Oracle需要的软件包
yum -y install binutils "compat-libstdc++" elfutils-libelf elfutils-libelf-devel expat gcc gcc-c++ glibc glibc-common glibc-devel glibc-headers libaio libaio-devel libgcc libstdc++ libstdc++ make "pdksh" sysstat unixODBC unixODBC-devel
yum -y install compat-libstdc++-33.x86_64 ksh.x86_64
yum -y install libaio.i686 glibc.i686 compat-libstdc++-33.i686 libaio-devel.i686 libgcc.i686 libstdc++.i686 unixODBC.i686 unixODBC-devel.i686
3。创建oracle用户
