oci_connect() works only from command line

问题

OK, so I have this terrible problem with oci, apache, php and suse. First off, versions:

PHP 5.3.15 (cli)
Apache/2.2.22 (Linux/SUSE)
OCI8 1.4.9
SUSE 12.2 32 bit
Oracle client 10.2.0.4

Problem

I have really simple php file:

<?php
    error_reporting(E_ALL);
    ini_set('display_errors', '1');
    oci_connect('user', 'passwd', 'host/sid');
?>

When I run it from command line it executes fine:

machine:~ # php oci.php
machine:~ #

But when i run it in browser, it gives me:

Warning: oci_connect() [function.oci-connect]: OCIEnvNlsCreate() failed. There is something wrong with your system - please check that ORACLE_HOME and LD_LIBRARY_PATH are set and point to the right directories

Apache configuration

I've been struggling with this issue for some time now and I'm pretty sure my apache configuration is correct.

I export all required variables before any apache process is started - I added

LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/path/to/oracle/home/lib; export LD_LIBRARY_PATH
ORACLE_HOME=/path/to/oracle/home; export ORACLE_HOME
TNS_ADMIN=/path/to/oracle/home/network/admin; export TNS_ADMIN
NLS_LANG=POLISH_POLAND.EE8MSWIN1250; export NLS_LANG

at the beginning of /etc/init.d/apache2 script (I start apache by /etc/init.d/apache2 start).

Apache runs from wwwrun user, who is in oinstall and dba groups:

machine:~ # cat /etc/apache2/uid.conf
User wwwrun
Group www
machine:~ # id wwwrun
uid=30(wwwrun) gid=8(www) groups=8(www),113(oinstall),114(dba)
machine:~ # l $ORACLE_HOME
total 216
drwxr-xr-x 48 oracle oinstall 4096 Jan 25 17:07 ./
drwxrwxr-x  3 oracle oinstall 4096 Jan 25 17:01 ../
...
machine:~ #

Possible problem

I don't have any environmental variables in Environment section in phpinfo(); output - could this be the problem? If yes, how can I fix this? Is it some kind of security issue? I've read about problems like that with SELinux enabled, but I don't have it, my firewall is off.

Solution?

Any help would be greatly appreciated!

回答1:

Problem solved! Thanks to these (Setting the Oracle Environment section) instructions and ken_yap's answer to this thread.

To put variables in Apache's Environment section you just have to add them in /etc/sysconfig/apache2 file: LD_LIBRARY_PATH=/path/to/oracle/lib.

回答2:

Another solution ( that do not need root access ) is to add this lines in the php page:

putenv("ORACLE_HOME=/opt/app/oracle/product/11.2.0/db_1");
putenv("LD_LIBRARY_PATH=/opt/app/oracle/product/11.2.0/db_1/lib:/lib:/usr/lib");

Regards

For Debian users - edit file

/etc/apache2/envvars

on the end of file add link to your OCI library - eg.

export LD_LIBRARY_PATH=/opt/oracle/instantclient_12_2

回答4:

Another approach for Centos 7 with nginx

$ sudo vim /etc/ld.so.conf.d/oracle-instantclient.conf

// Add path to oracle client lib, the XX is the version, ex: /usr/lib/oracle/XX/client64/lib 

$ sudo ldconfig
$ sudo service php-fpm restart

Done!
