Installation on Unix systems Apache 2.0 on Unix systems

You are highly encouraged to take a look at the » Apache Documentation to get a basic understanding of the Apache 2.0 Server.
PHP and Apache 2.0.x compatibility notes: The following versions of PHP are known to work with the most recent version of Apache 2.0.x:
PHP 4.3.0 or later available at »
the latest stable development version. Get the source code » or download binaries for Windows »
a prerelease version downloadable from »
you have always the option to obtain PHP through » anonymous CVS. These versions of PHP are compatible to Apache 2.0.40 and later.
Apache 2.0 SAPI-support started with PHP 4.2.0. PHP 4.2.3 works with Apache 2.0.39, don't use any other version of Apache with PHP 4.2.3. However, the recommended setup is to use PHP 4.3.0 or later with the most recent version of Apache2.
All mentioned versions of PHP will work still with Apache 1.3.x.
Download the most recent version of » Apache 2.0 and a fitting PHP version from the above mentioned places. This quick guide covers only the basics to get started with Apache 2.0 and PHP. For more information read the » Apache Documentation. The version numbers have been omitted here, to ensure the instructions are not incorrect. You will need to replace the 'NN' here with the correct values from your files.

1. gzip -d httpd-2_0_NN.tar.gz2. tar xvf httpd-2_0_NN.tar3. gunzip php-NN.tar.gz4. tar -xvf php-NN.tar5. cd httpd-2_0_NN6. ./configure --enable-so7. make8. make install Now you have Apache 2.0.NN available under /usr/local/apache2, configured with loadable module support and the standard MPM prefork. To test the installation use your normal procedure for starting the Apache server, e.g.: /usr/local/apache2/bin/apachectl start and stop the server to go on with the configuration for PHP: /usr/local/apache2/bin/apachectl stop.9. cd ../php-NN10. Now, configure your PHP. This is where you customize your PHP with various options, like which extensions will be enabled. Do a ./configure --help for a list of available options. In our example we'll do a simple configure with Apache 2 and MySQL support. Your path to apxs may differ, in fact, the binary may even be named apxs2 on your system. ./configure --with-apxs2=/usr/local/apache2/bin/apxs --with-mysql11. make12. make install If you decide to change your configure options after installation, you only need to repeat the last three steps. You only need to restart apache for the new module to take effect. A recompile of Apache is not needed. Note that unless told otherwise, 'make install' will also install PEAR, various PHP tools such as phpize, install the PHP CLI, and more. 13. Setup your php.ini cp php.ini-dist /usr/local/lib/php.ini You may edit your .ini file to set PHP options. If you prefer having php.ini in another location, use --with-config-file-path=/some/path in step 10. If you instead choose php.ini-recommended, be certain to read the list of changes within, as they affect how PHP behaves.14. Edit your httpd.conf to load the PHP module. The path on the right hand side of the LoadModule statement must point to the path of the PHP module on your system. The make install from above may have already added this for you, but be sure to check. For PHP 4: LoadModule php4_module modules/ For PHP 5: LoadModule php5_module modules/ 15. Tell Apache to parse certain extensions as PHP. For example, let's have Apache parse the .php extension as PHP. You could have any extension(s) parse as PHP by simply adding more, with each separated by a space. We'll add .phtml to demonstrate. AddType application/x-httpd-php .php .phtml It's also common to setup the .phps extension to show highlighted PHP source, this can be done with: AddType application/x-httpd-php-source .phps 16. Use your normal procedure for starting the Apache server, e.g.: /usr/local/apache2/bin/apachectl start
