我想要做的是通过perl从oracle数据库连接和检索数据。
我所做的（如oracle帐户）如下所示......
$ rpm -qa|grep DBI
perl-DBI-1.52-2.el5
$ wget http://search.cpan.org/CPAN/authors/id/P/PY/PYTHIAN/DBD-Oracle-1.17.tar.gz
$ tar -zxf DBD-Oracle-1.17.tar.gz
$ cd DBD-Oracle-1.17

我的机器在CentOS 5.5版和10g企业版10.2.0.5.0版上...
我错过了什么？
答案 0 :(得分：2)
听起来像SELinux的问题。尝试禁用它，看看这是否可以解决您的问题： http://www.crypt.gen.nz/selinux/disable_selinux.html
答案 1 :(得分：1)
我不知道你错过了什么以及你哪里出错了。但我总是遵循以下方法，它已经为我工作了100％。尝试这种方法，如果它不起作用，那么我绝对可以让它适合你......
我在帖子中注意到的一件事是您遇到了权限问题。尝试以root身份运行这些步骤。
我的环境：在远程控制台上运行的Oracle 11G
我的桌面：ubunt / fedora / RHEL / CenOS
我已经在上述4种Linux版本中实现了这一点，它们都能很好地工作。
以下是步骤（按照给出的顺序）：
安装Perl DBI模块
从http://www.oracle.com/technetwork/topics/linuxx86-64soft-092277.html
安装低于3 rpm的oracle即时客户端oracle-instantclient11.2-basic-11.2.0.3.0-1
oracle-instantclient11.2-devel-11.2.0.3.0-1
oracle-instantclient11.2-sqlplus-11.2.0.3.0-1
我使用的是64位linux盒子，因此请相应选择你的RPM。
设置以下变量：
LD_LIBRARY_PATH=/usr/lib/oracle/11.2/client64/lib
ORACLE_HOME=/usr/lib/oracle/11.2/client64
还将ORACLE_HOME添加到您的PATH变量
从CPAN下载DBD::Oracle ver 1.44。
解压模块并按给定顺序运行以下命令：
perl Makefile.PL
make make
install
完成!!!
