Installing PHP on Apache 2

This page describes how to setup php on Apache2. PHP 4.3.0 with Apache 2.0.46 was used on Redhat 8.

Install Apache

Follow these instructions to Install Apache2 from source.

Download the latest PHP sources

Download the PHP tar.gz from php.net

Extract the source code

Extract the source code to a directory under /usr/local/src

cp php-4.3.0.tar.gz /usr/local/src
cd /usr/local/src
gunzip php-4.3.0.tar.gz
tar -xvf php-4.3.0.tar
rm -f php-4.3.0.tar
cd php-4.3.0

Set compiler options (optional)

If you want you can set some compiler options, this is typically done to create optimized code. One very common thing to do is to set CFLAGS=-O2 or CFLAGS=-O3 (that's an Oh, not a Zero) that tells the compiler how much code optimization to do, setting it to a higher value does more optimization, but also takes longer to compile and may potentially cause unexpected things (not common). O2 is a fairly safe level to use. To do this type the following:

export CFLAGS=-O2
You can also tell the compiler what kind of CPU you have to perform more optimizations, I'm not going to get into that here, but if your interested check out the GCC manual.

Configure php with autoconf

Now you need to set the configuration options, and check that all libraries needed to compile are present. This is done with a script called configure, to find out what options you can set type the following:

./configure --help
You will see quite a few options, here's a page that defines the configure options. We will tell configure to enable mysql, and also tell it where to find apxs Apache's tool for building modules.
configure --with-mysql --with-apxs2=/usr/local/apache2/bin/apxs

Compile PHP

make

Install PHP

make install

Tell apache to load the module Edit httpd.conf /usr/local/apache2/conf/httpd.conf with your text editor. Add the following to httpd.conf

Include conf.d/*.conf
This allows you to create a specific configuration file for each module that you install, for instance php.conf Now create a directory in your apache directory if its not there called conf.d
mkdir /usr/local/apache2/conf.d
cd /usr/local/apache2/conf.d
Make a file called php.conf located at /usr/local/apache2/conf.d/php.conf with the contents:
# PHP Configuration for Apache
#
# Load the apache module
#
LoadModule php4_module modules/libphp4.so
#
# Cause the PHP interpreter handle files with a .php extension.
#
<Files *.php>
SetOutputFilter PHP
SetInputFilter PHP
LimitRequestBody 9524288
</Files>
AddType application/x-httpd-php .php
AddType application/x-httpd-php-source .phps
#
# Add index.php to the list of files that will be served as directory
# indexes.
#
DirectoryIndex index.php
Note you could have just inserted the above in your httpd.conf file, and omit the conf.d step if you desire. I feel that the conf.d approch is a cleaner way to do it.

That's it, restart apache and you should have PHP working.

Note: To install PostgreSQL support on redhat 9 with php/apache2 you will need to install the postgresql libs, and devel rpms, and add --with-pgsql to your configure line

Thanks, Jonathan Crowe for suggesting the AddType directive.

Thanks, it worked.
Worked for me also thanks But configuring php with mysql was problamatic as mysql header files were not present on my linux box so i did following · To connect with mysql install mysql header files > Download MySQL-devel-standard-5.0.22-0.rhel3.i386.rpm from http://dev.mysql.com/downloads/mysql/5.0.html (http://dev.mysql.com/get/Downloads/MySQL-5.0/MySQL-devel-standard-5.0.22-0.rhel3.i386.rpm/from/http://mirror.switch.ch/ftp/mirror/mysql/) > Change directory to the directory containing MySQL-devel-standard-5.0.22-0.rhel3.i386.rpm > rpm ?ivh MySQL-devel-standard-5.0.22-0.rhel3.i386.rpm
how to configure. apache and php ? the apache tell error for no service installer then Apache"

The Application has failed to start because OCI.dll was not found.Re-installing the application may fix this problem.

Thanks buddy It really works. This issue had wasted my 3 days. Again thanks
the link to the apache installation does not work.

Also I am getting an error about libxml2 when attempting to ./configure php
Hi,

Thanks it really helped. Just want to comment that using "export CFLAGS=-O2" teh configure was giving error while checking for C-compiler. if we don't export CFLAGS it worked fine.
Yes! It Works!! Thank you very much!!
