下载

从oracle官方网站上下载客户端和sqlplus程序。

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
配置
vim /etc/profile 添加
export ORACLE_HOME=/usr/lib/oracle/11.1.0.1/client64 export ORACLE_BASE=/usr/lib/oracle/11.1.0.1 export LD_LIBRARY_PATH=$ORACLE_HOME/lib:$LD_LIBRARY_PATH export NLS_LANG=AMERICAN_AMERICA.AL32UTF8

设置好环境变量需要重启机器！

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.

ORCL =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.15.111)(PORT = 1521))
(CONNECT_DATA =
(SERVICE_NAME = dmsdb)
)
)

测试

到ORACLE_HOME/bin目录下，执行命令：

[yleesun@centos bin]$ ./sqlplus zxd/zxd@ORCL
[yleesun@centos bin]$ ./sqlplus zxd/zxd@111
