cent os 7.2安装oracle 12cr2

1、最小化安装linux，配置好yum源

安装依赖包

yum  -y install binutils compat-libcap1 gcc gcc-c++ glibc glibc.i686 glibc-devel glibc.i686 ksh libaio libaio.i686 libaio-devel libaio-devel.i686 libgcc libgcc.i686 libstdc++ libstdc++l7.i686 libstdc++-devel libstdc++-devel.i686 compat-libstdc++-33 compat-libstdc++-33.i686 libXi libXi.i686 libXtst libXtst.i686 make sysstat smartmontools net-tools

---其他包 解压，xmanager远程

yum  -y install   unzip install xorg-x11-server-utils xorg-x11-utils
