如何在linux下安装Oracle 客户端

Answer 1

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_64.rpm
rpm-ivh oracle-instantclient-sqlplus-11.1.0.1-1.x86_64.rpm

2、配置
vim/etc/profile 添加
exportORACLE_HOME=/usr/lib/oracle/11.1.0.1/client64
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/client64/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
