Apache 2 MPM Event with PHP-FPM, FCGID and SUEXEC on Debian Jessie
The goal of this setup is having a high-performance state-of-the-art deployment of Apache and PHP while being compatible with legacy applications.
-
Apache Event MPM engine handles requests asynchronously, instead of using a dedicated thread or process per request.
-
PHP-FPM is a FastCGI process manager included in modern versions of PHP. Compared to FCGID it provides better process management features and enables the OPCache to be shared between workers.
-
FCGID and SuEXEC are used for legacy apps that need older versions of PHP (i.e. PHP 5.2 or PHP 4)
