准备好如下三个安装包，放在某个目录下，如：/root/software/oracle
[root@localhost oracle]# pwd
/root/software/oracle
[root@localhost oracle]# ls
oracle-instantclient11.2-basic-11.2.0.2.0.i386.rpm
oracle-instantclient11.2-devel-11.2.0.2.0.i386.rpm // 这个是SDK开发包
oracle-instantclient11.2-sqlplus-11.2.0.2.0.i386.rpm
[root@localhost oracle]#
创建目标文件夹（oracle将安装在/opt/下）
[root@localhost opt]# mkdir oracle
[root@localhost opt]# mkdir oracle/network oracle/sdk
[root@localhost opt]# mkdir oracle/network/admin
解压其中2个rpm包（basic, sqlplus)
[root@localhost ~]# cd /root/software/oracle
[root@localhost oracle]# pwd
/root/software/oracle
[root@localhost oracle]# ls
oracle-instantclient11.2-basic-11.2.0.2.0.i386.rpm
oracle-instantclient11.2-devel-11.2.0.2.0.i386.rpm
oracle-instantclient11.2-sqlplus-11.2.0.2.0.i386.rpm
[root@localhost oracle]# rpm2cpio oracle-instantclient11.2-basic-11.2.0.2.0.i386.rpm | cpio -div

usr
将解压出来的usr目录下的bin和lib移动到/opt/oracle/下，再删除usr目录：
[root@localhost oracle]# mv usr/lib/oracle/11.2/client/bin /opt/oracle/
[root@localhost oracle]# mv usr/lib/oracle/11.2/client/lib /opt/oracle/
[root@localhost oracle]# rm -rf usr
解压剩下的rpm包(devel)
[root@localhost oracle]# rpm2cpio oracle-instantclient11.2-devel-11.2.0.2.0.i386.rpm | cpio -div
