After installing your httpd.conf is modified by axps. It should now look as follows:
<IfDefine SSL> LoadModule ssl_module libexec/libssl.so LoadModule php4_module libexec/libphp4.so </IfDefine> |
If you compiled Apache with mod_ssl then the php-module will only be loaded when staring Apache with ssl (apachectl startssl). If you will start Apache without ssl support (but compiled like described in this document) you need to change this:
<IfDefine SSL> LoadModule ssl_module libexec/libssl.so </IfDefine> LoadModule php4_module libexec/libphp4.so |
Copy the sample php.ini to /usr/local/lib/php.ini
cp /usr/local/php-4.1.2/php.ini-dist /usr/local/lib/php.ini |
uncomment (remove the # at begin of line) the following lines in /usr/local/apache/conf/httpd.conf
Apache 1.3.23 default httpd.conf does lack of this entries. You have to add them instead of uncommenting
AddType application/x-httpd-php .php AddType application/x-httpd-php-source .phps |
you may wish to add the following:
AddType application/x-httpd-php .phtml AddType application/x-httpd-php .php3 |
Restart apache by issuing the following command:
/usr/local/apache/bin/apachectl restart |
