Installation

PHP provides a setting with the name auto_prepend_file to automatically load additional PHP files every time the PHP binary is called. This can be used to load the connector on every request before the actual script is executed without having to change a single line of code.

To install the connector you have to move the directory src to a location that is accessible by the web server, e.g., /usr/share/shadowd/php.

Global

If you want to enable Shadow Daemon globally you can set auto_prepend_file to /usr/share/shadowd/Connector.php in the php.ini. The change will take effect after you restart your web server, but you should wait with that until the configuration of the module is completely done.

Apache

If you are using Apache you can use php_value to set auto_prepend_file for specific vhosts or directories.

php_value  auto_prepend_file  "/usr/share/shadowd/php/Connector.php"

Nginx

If you are using NGINX you can use fastcgi_param to set auto_prepend_file for specific vhosts or directories.

fastcgi_param  PHP_ADMIN_VALUE  "auto_prepend_file=/usr/share/shadowd/php/Connector.php";

Configuration

Copy the configuration file from misc/examples/connectors.ini to /etc/shadowd/connectors.ini and edit it. The file is annotated and should be self-explanatory, but if you are stuck you can find more information in the documentation. Make sure that it is readable by the web server user, otherwise your site will not work anymore.

If you plan to protect multiple applications you can use the environment variable SHADOWD_CONNECTOR_CONFIG to specify different configuration files for every target.
