This section holds common questions about the way to install PHP. PHP is available for almost any OS (except may be for MacOS before OSX), and almost any web server.
To install PHP, follow the instructions in the INSTALL file located in the distribution. Windows 95 and NT users should also read the install.txt file. There are also some helpful hints for Windows users here.
If you are trying to install PHP for use with Netscape's web server on Unix see: http://www.webgenx.com/php/phpnes.php3
By default on UNIX it should be in /usr/local/lib. Most people will want to change this at compile-time with the --with-config-file-path flag. You would, for example, set it to something like:
--with-config-file-path=/etc

Assuming you installed both Apache and PHP from RPM packages, you need to uncomment or add some or all of the following lines in your http.conf file:
# Extra Modules
AddModule mod_php.c
AddModule mod_php3.c
AddModule mod_perl.c
# Extra Modules
LoadModule php_module modules/mod_php.so
LoadModule php3_module modules/libphp3.so /* for PHP 3 */
LoadModule php4_module modules/libphp4.so /* for PHP 4 */
LoadModule perl_module modules/libperl.so
|
AddType application/x-httpd-php3 .php3 /* for PHP 3 */
AddType application/x-httpd-php .php /* for PHP 4 */

3. I installed PHP using RPMS, but it doesn't compile with the database support I need! What's going on here?
Due to the way PHP is currently built, it is not easy to build a complete flexible PHP RPM. This issue will be addressed in PHP 4. For PHP, we currently suggest you use the mechanism described in the INSTALL.REDHAT file in the PHP distribution. If you insist on using an RPM version of PHP, read on...
Currently the RPM packagers are setting up the RPMS to install without database support to simplify installations and because RPMS use /usr/ instead of the standard /usr/local/ directory for files. You need to tell the RPM spec file which databases to support and the location of the top-level of your database server.
This example will explain the process of adding support for the popular MySQL database server, using the mod installation for Apache.
Of course all of this information can be adjusted for any database server that PHP supports. We will assume you installed MySQL and Apache completely with RPMS for this example as well.
First remove mod_php3 :
rpm -e mod_php3
|
Then get the source rpm and INSTALL it, NOT --rebuild
rpm -Uvh mod_php3-3.0.5-2.src.rpm
|
Then edit the /usr/src/redhat/SPECS/mod_php3.spec file
In the %build section add the database support you want, and the path.
For MySQL you would add
--with-mysql=/usr \
|
./configure --prefix=/usr \
--with-apxs=/usr/sbin/apxs \
--with-config-file-path=/usr/lib \
--enable-debug=no \
--enable-safe-mode \
--with-exec-dir=/usr/bin \
--with-mysql=/usr \
--with-system-regex
|
Once this modification is made then build the binary rpm as follows:
rpm -bb /usr/src/redhat/SPECS/mod_php3.spec
|
Then install the rpm
rpm -ivh /usr/src/redhat/RPMS/i386/mod_php3-3.0.5-2.i386.rpm
