转自：http://blog.csdn.net/wuxiaoyan_home/article/details/4826440

安装：

rpm -ivh oracle-instantclient-basic-10.2.0.4-1.i386.rpm
rpm -ivh oracle-instantclient-sqlplus-10.2.0.4-1.i386.rpm
rpm -ivh oracle-instantclient-devel-10.2.0.4-1.i386.rpm

添加路径：

cd /etc/profile
export ORACLE_HOME=/usr/lib/oracle/11.2/client64
export TNS_ADMIN=$ORACLE_HOME/network/admin
export NLS_LANG='simplified chinses_china'.ZHS16GBK
export LD_LIBRARY_PATH=$ORACLE_HOME/lib
export PATH=/usr/bin:/usr/sbin:$ORACLE_HOME/bin:

修改sqlplus配置文件：

vi /usr/lib/oracle/11.2/client64/network/admin/tnsnames.ora
ORCL =
(DESCRIPTION =
((ADDRESS = (PROTOCOL = TCP)(HOST = *IP*)(PORT = 1521I)
(CONNECT_DATA =
(SERVER = DEDICATED )
(SERVER_NAME=*SID*)
)
)

一、下载Oracle 10g sqlplus软件

http://www.oracle.com/technology/software/tech/oci/instantclient/index.html

oracle-instantclient-basic-10.2.0.4-1.i386.rpm

oracle-instantclient-sqlplus-10.2.0.4-1.i386.rpm

oracle-instantclient-devel-10.2.0.4-1.i386.rpm

二、安装rpm包

rpm -ivh oracle-instantclient-basic-10.2.0.4-1.i386.rpm
rpm -ivh oracle-instantclient-sqlplus-10.2.0.4-1.i386.rpm
rpm -ivh oracle-instantclient-devel-10.2.0.4-1.i386.rpm

三、指定sqlplus运行所需要的库

由于是RPM包安装的，因此，oracle客户端默认所在的路径为/usr/lib/oracle/10.2.0.4/client/lib/

#vi /etc/ld.so.conf

在最后加入：/usr/lib/oracle/10.2.0.4/client/lib

四、重启ldconfig

ldconfig

五、启动sqlplus

sqlplus /nolog

一、配置oracle环境变量

#vi /etc/profile最后加入
export ORACLE_HOME=/usr/lib/oracle/10.2.0.4/client
export LD_LIBRARY_PATH=:$ORACLE_HOME/lib:/usr/local/lib:$LD_LIBRARY_PATH:.
export TNS_ADMIN=$ORACLE_HOME
export PATH=$PATH:$ORACLE_HOME/bin:.

六、配置连接tnsnames.ora

#cd $ORACLE_HOME加入

test =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = ip)(PORT = 1521))
)
(CONNECT_DATA =
(SID = test )
(SERVER=DEDICATED )
)
)
```
七、启动

```c++
sqlplus 用户名/密码@//IP:PORT/会话ID
