FPM uses libevent to manage connections and signals. Minimum required version is libevent-1.4.11.
Compiling from sources
In order to enable FPM in your PHP build you need to add --enable-fpm to your configure line.
There are several other FPM-specific configure options (all of them optional):
--with-fpm-user - set FPM user (default - nobody).
--with-fpm-group - set FPM group (default - nobody).
An init startup script file can be found at :
after successful compilation.
