What is PHP-FPM?

PHP-FPM is a PHP-specific process manager that implements FastCGI protocol for managing PHP-CGI.

Install

The PHP-FPM is integrated into PHP after PHP5.3.3 and does not need to be installed separately.

Use

Start

➜  ~  sudo php-fpm[15-Feb-2015 15:52:10] NOTICE: fpm is running, pid 6995[15-Feb-2015 15:52:10] NOTICE: ready to handle connections

The second line above is the process number pid 6995 after php-fpm is started.
After starting in this way, php-fpm will occupy the terminal for running.
