Question

ENV：

Red Hat Enterprise Linux Server release 6.4 
Apache/2.2.15 (Unix) mod_perl/2.0.4 Perl/v5.10.1
Perl v5.10.1 (*) built for x86_64-linux-thread-multi
64 bit Oracle client for 11.2
DBD::Oracle : Oracle Driver for DBI ; P/PY/PYTHIAN/DBD-Oracle-1.64.tar.gz : /usr/local/lib64/perl5/DBD/Oracle.pm : Installed: 1.64 
/home/oracle/app/oracle/product/11.2.0/client_1/lib/libclntsh.so.11.1: ELF 64-bit LSB shared object, x86-64, version 1 (SYSV), dynamically linked, not stripped 
-rwxr-xr-x. 1 oracle oracle 48725761 Jun 10 17:41 /home/oracle/app/oracle/product/11.2.0/client_1/lib/libclntsh.so.11.1

Startup.pl

use lib qw(/home/oracle/app/oracle/product/11.2.0/client_1/lib);
BEGIN {
    $ENV{ORACLE_HOME}     = '/home/oracle/app/oracle/product/11.2.0/client_1';
    $ENV{LD_LIBRARY_PATH} = '/home/oracle/app/oracle/product/11.2.0/client_1/lib';
    $ENV{ORACLE_SID}      = 'MARS';
}
print STDERR "\nORACLE_HOME = " . $ENV{'ORACLE_HOME'} . "\n";
print STDERR "\nLD_LIBRARY_PATH = " . $ENV{'LD_LIBRARY_PATH'} . "\n";

use mod_perl2;
use Apache::DBI ();
use DBI ();
use DBD::Oracle;

BEGIN { use Data::Dumper; print STDERR Dumper(\@INC); }
print STDERR "ModPerl2 Startup.pl\n";
foreach ( keys %ENV ) {
    print STDERR "$_\t$ENV{$_}\n";
}
1;

Apache conf

PerlRequire /var/www/cgi-bin/startup.pl
SetEnv ORACLE_HOME "/home/oracle/app/oracle/product/11.2.0/client_1"
SetEnv LD_LIBRARY_PATH "/home/oracle/app/oracle/product/11.2.0/client_1/lib"

错误：

Can't load '/usr/local/lib64/perl5/auto/DBD/Oracle/Oracle.so' for module DBD::Oracle: libclntsh.so.11.1: cannot open shared object file: No such file or directory at /usr/lib64/perl5/DynaLoader.pm line 200.\n at /var/www/cgi-bin/startup.pl line 17\nCompilation failed in require at /var/www/cgi-bin/startup.pl line 17.\nBEGIN failed--compilation aborted at /var/www/cgi-bin/startup.pl line 17.\nCompilation failed in require at (eval 2) line 1.\n

Startup.pl在从命令行运行时有效，但无法通过Apache加载

事情已经尝试过了

在Apache conf中设置env变量（如上所示）
检查oracle库的文件permisison
从命令行打印env变量，并在从Apache运行时与输出进行比较（删除DBD :: Oracle后）
确保所有Perl，Apache，Oracle，DBD：Oracle都是64位
将/home/oracle/app/oracle/product/11.2.0/client_1/lib添加到/etc/ld.so.conf并运行ldconf

Answer 1

该错误来自Apache无法找到Oracle安装。将您的Oracle $ PATH环境变量放在bin / envvars文件中，如下所示：

ORACLE_HOME="/home/oracle/app/oracle/product/11.2.0/client_1"
LD_LIBRARY_PATH="/home/oracle/app/oracle/product/11.2.0/client_1/lib"

export LD_LIBRARY_PATH ORACLE_HOME

Answer 2

你的DBD::Oracle是针对11.1构建的，正如错误消息所证明的那样，它正在寻找一个特别命名的/版本化的.so文件（“libclntsh.so.11.1”）。

但是，您的运行时配置为11.2，由您的路径证明，并且不提供具体命名/版本化的.so文件。

为您首选的运行时配置重建DBD::Oracle并从那里开始。

Answer 3

这可能是一个selinux问题。如果您的脚本从shell运行良好但不能从apache运行，请尝试禁用selinux。

如果有帮助，您可以更好地配置selinux，而不仅仅是禁用它。

Answer 4

在RHEL（5,6和7）上有相同的错误消息。这就是最终为我解决的问题：

echo $ORACLE_HOME/lib >> /etc/ld.so.conf
/sbin/ldconfig
service httpd stop; service httpd start

无法使用Apache / Mod_Perl中的DBD :: Oracle
