linux下安装Oracle客户端步骤如下：
1、下载
从Oracle官方网站上下载客户端和sqlplus程序。
以root用户安装
rpm-ivh oracle-instantclient-basic-11.1.0.1-1.x86_.rpm
rpm-ivh oracle-instantclient-sqlplus-11.1.0.1-1.x86_.rpm
2、配置
vim/etc/profile 添加
exportORACLE_HOME=/usr/lib/oracle/11.1.0.1/client
exportORACLE_BASE=/usr/lib/oracle/11.1.0.1
exportLD_LIBRARY_PATH=$ORACLE_HOME/lib:$LD_LIBRARY_PATH
exportNLS_LANG=AMERICAN_AMERICA.AL32UTF8
设置好环境变量需要重启机器！
3、创建配置文件
在ORACLE_HOME目录下创建以下目录network/admin,并创建文件tnsnames.ora,内容如下:
vim/usr/lib/oracle/11.1.0.1/client/network/admin/tnsnames.ora
# tnsnames.ora Network Configuration File:/opt/oracle10g/u01/network/admin/tnsnames.ora
# Generated by Oracle configuration tools.
111 =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.15.111)(PORT = 1521))
)
(CONNECT_DATA =
(SERVICE_NAME = dmsdb)
)
)
4、测试
到ORACLE_HOME/bin目录下，执行命令：
[yleesun@centosbin]$ ./sqlplus zxd/zxd@111

测试成功！
注：
如果出现以下错误：
sqlplus:error while loading shared libraries: libsqlplus.so: cannot open shared objectfile: No such file or directory
说明环境变量没有生效！
