一、下载必要的资源包
从oracle官方网站上下载安装包，选择version 10.1.0.5即可。
version 10.1.0.5   instant client package - basic: all files required to run oci, occi, and jdbc-oci applications
instantclient-basic-linux32-10.1.0.5-20060511.zip (31,413,713 bytes) (cksum - 384697539)
*instant client package - jdbc supplement: additional support for xa, internationalization, and rowset operations under jdbc
instantclient-jdbc-linux32-10.1.0.5-20060511.zip (4,649,614 bytes) (cksum - 753190421)
*instant client package - sql*plus: additional libraries and executable for running sql*plus with instant client 
instantclient-sqlplus-linux32-10.1.0.5-20060511.zip (331,854 bytes) (cksum - 722849044)
*instant client package - sdk: additional header files and an example makefile for developing oracle applications with instant client 
instantclient-sdk-linux32-10.1.0.5-20060511.zip (294,618 bytes) (cksum - 4282446920)
optional packages are marked with a *.
installation steps:
1. download the appropriate instant client packages for your platform. all installations require the basic package.
2. unzip the packages into a single directory such as instantclient.
3. set the library loading path in your environment to the directory in step 2 (instantclient). on many unix platforms, ld_library_path is the appropriate environment variable. on windows, path should be used.
4. start your application and enjoy.
二、目录安排
         把上述几个文件解压到/home/ instantclient10_1目录中
/home/ instantclient10_1
                  |_bin
                     |_sqlplus
                  |_lib
                     |_ libclntsh.so.10.1，libnnz10.so，libociei.so，libsqlplus.so
                  |_network
                     |_admin
                     |_tnsnames.ora
                  |_sqlplus
                     |_admin
                         |_glogin
                     |_mesg
                         |_sp1us.msb，sp1us.msg，sp1zhs.msb等
         tnsnames.ora文件可以从x:\oracle\product\10.2.0\db_1\network\admin目录下拷贝即可，，这样您只要保证在windows下该文件配置正确即可。
三、环境变量配置
        1、在/etc/profile文件里添加如下配置
oracle_home=/home/instantclient10_1
path=$oracle_home/bin:$path
ld_library_path=$oracle_home/lib:$ld_library_path
export oracle_home path ld_library_path
       2、生效命令
#source profile
       3、环境变量查看
#env |grep oracle_home
四、验证效果
        使用sqlplus查询，如果出现如下信息，orale client基本安装完成。
用户名:username
密  码: password
服务名: myoracle
三项基本信息要根据你自己系统实际配置。
# sqlplus username/password@myoracle
