Apache loading PHP module - undefined symbol: unixd_config

Question

I'm configuring a new web server on a RedHat 6.5.

I try to enable the php5 module on Apache 2.4.6 as following:

LoadModule php5_module /usr/path/to/libphp5.so
AddType application/x-httpd-php .php

When I check the httpd.conf file with Apache I get the following error about the LoadModule's line:

Cannot load /usr/path/to/libphp5.so into server: /usr/path/to/libphp5.so: undefined symbol: unixd_config

I wonder if the problem is because I've two PHP versions installed. The one Apache should use is the alias php55, what is the configuration to do for it ?

Answer 1

The Apache API changed from 2.2 to 2.4, unixd_config was renamed ap_unixd_config (see Api changes from 2.2 to 2.4). You need a php module version that is compatible with Apache 2.4 or stay with Apache 2.2.

Answer 2

Finally I use:

<FilesMatch \.php$>
    SetHandler application/x-httpd-php
</FilesMatch>
PHPIniDir "/path/to/php/lib"

And I build libphp5.so by my own.

Answer 3

The correct approach is to install the following package. Replace php55 with your desired version here. Software is pulled from RH Software Collection. This package contains the module (often referred to as mod_php) which adds support for php to Apache 2.4

yum install rh-php55-php
