五、测试链接

 

一、安装unixODBC

sudo yum install -y unixODBC

二、下载Oracle客户端依赖包和Oracle ODBC驱动包

需要下载instantclient-basic-linux-12.1.0.2.0.zip 和  instantclient-odbc-linux-12.1.0.2.0.zip

三、安装

mkdir /usr/local/oracle
unzip instantclient-basic-linux-12.1.0.2.0.zip -d /usr/local/oracle/
unzip instantclient-odbc-linux-12.1.0.2.0.zip -d /usr/local/oracle/
export LD_LIBRARY_PATH=/usr/local/oracle/instantclient_12_1:$LD_LIBRARY_PATH
echo -en 'export LD_LIBRARY_PATH=/usr/local/oracle/instantclient_12_1:$LD_LIBRARY_PATH' >> ~/.bashrc

四、配置数据源

配置/etc/odbcinst.ini

[ORAC12c]
Description     = Oracle ODBC driver for Oracle 12c
Driver          = /usr/local/oracle/instantclient_12_1/libsqora.so.12.1
Setup           =
FileUsage       =
CPTimeout       =
CPReuse         =

 配置/etc/odbc.ini

[orac]
Description = ODBC for Oracle
Driver      = ORAC12c
ServerName = 10.10.23.19:1521/orcl11g.us.oracle.com
