本文详细介绍了如何在CentOS 5.5环境下安装Oracle Instant Client，包括基本软件包的下载与安装、环境变量的配置及测试过程。

环境
os版本：centos5.5
kernel： 2.6.18-194.el5

下载软件包：
oracle-instantclient-basic-10.2.0.5-1.x86_64.rpm
oracle-instantclient-devel-10.2.0.5-1.x86_64.rpm
oracle-instantclient-sqlplus-10.2.0.5-1.x86_64.rpm

下载地址：
http://www.oracle.com/technetwork/database/features/instant-client/index-097480.html

指定rpm包的安装路径

1. 查看rpm包的默认安装路径
[root@localhost tmp]# rpm -qpl oracle-instantclient-sqlplus-10.2.0.5-1.x86_64.rpm
/usr/bin/sqlplus64
/usr/lib/oracle/10.2.0.5/client64/bin/sqlplus
/usr/lib/oracle/10.2.0.5/client64/lib/glogin.sql

3个包都需要检测，为了以后便于维护，可以把instantclient都装在目录"/oracle"

[root@localhost tmp]# rpm -ivh --relocate /usr=/oracle oracle-instantclient-basic-10.2.0.5-1.x86_64.rpm
[root@localhost tmp]# rpm -ivh --relocate /usr=/oracle oracle-instantclient-devel-10.2.0.5-1.x86_64.rpm
[root@localhost tmp]# rpm -ivh --relocate /usr=/oracle oracle-instantclient-sqlplus-10.2.0.5-1.x86_64.rpm

2.sqlnet.ora和tnsnames.ora创建
这两个文件默认是不存在，所以要手工创建
[root@localhost tmp]# mkdir -p /oracle/lib/oracle/10.2.0.5/client64/network/admin

然后在admin目录下创建这两个文件

3.配置环境变量

session级别设置
export LD_LIBRARY_PATH=/oracle/lib/oracle/10.2.0.5/client64/lib
export TNS_ADMIN=/oracle/lib/oracle/10.2.0.5/client64/network/admin
export ORACLE_HOME=/oracle/lib/oracle/10.2.0.5/client64

把如下内容放在环境变量文件中
[root@localhost ~]# vi /root/.bash_profile
.....
export TNS_ADMIN=/oracle/lib/oracle/10.2.0.5/client64/network/admin
export LD_LIBRARY_PATH=/oracle/lib/oracle/10.2.0.5/client64/lib
export PATH=$PATH:$HOME/bin:/oracle/lib/oracle/10.2.0.5/client64/bin

......

4.测试

[root@localhost ~]# sqlplus "/@tns "

SQL*Plus: Release 10.2.0.5.0 - Production on Thu Aug 9 03:03:26 2012
