oracle客户端的安装是非常简单的，关键在tns配置，我这里使用的rpm安装包，oracle本身就不是开源，那使用rpm安装时最简单的。
1.要远程使用oracle，先下载下面三个文件，注意版本最好一致。
|
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 |
2.PM安装
|
oracle-instantclient-basic-10.2.0.4-1.i386.rpm是基本的动态库、jar包，默认安装路径是：/usr/lib/oracle/10.2.0.4/client oracle-instantclient-sqlplus-10.2.0.4-1.i386.rpm是客户端sqlplus安装包, 默认安装路径是：/usr/lib/oracle/10.2.0.4/client oracle-instantclient-devel-10.2.0.4-1.i386.rpm是api接口文件,默认安装路径是：/usr/include/oracle/10.2.0.4/client |
这里不需要修改默认路径,直接安装即可：
|
sudo rpm-avi oracle-instantclient-basic-10.2.0.4-1.i386.rpm sudo rpm-avi oracle-instantclient-sqlplus-10.2.0.4-1.i386.rpm sudo rpm-avi oracle-instantclient-devel-10.2.0.4-1.i386.rpm |
3.配置环境变量
|
vi /etc/profile export ORACLE_HOME=/usr/lib/oracle/10.2.0.4 export TNS_ADMIN=$ORACLE_HOME/network/admin export NLS_LANG=AMERICAN_AMERICA.ZHS16GBK exportLD_LIBRARY_PATH=$ORACLE_HOME/client/lib:$LD_LIBRARY_PATH exportOCI_HEADERS_HOME=/usr/include/oracle/10.2.0.4/client export OCI_LIBS_HOME=$ORACLE_HOME/client/lib |
后面两项是为了我们的程序程序编译时使用方便，编译时直接加入选项：
-I$( OCI_HEADERS_HOME) –L$( OCI_LIBS_HOME) –l occi
4.配置监听器和网络环境
|
[huangxw@ubuntu admin]$ cat/usr/lib/oracle/10.2.0.4/network/admin/tnsnames.ora test_base= (DESCRIPTION = (ADDRESS_LIST = (ADDRESS = (PROTOCOL = TCP)(HOST = *.*.*.*)(PORT = ****)) ) (CONNECT_DATA = (SERVICE_NAME = tt4adol) ) ) |
5.测试连接
|
