# Description: PHP-FastCgi start script from http://blog.kovyrin.net/2006/05/30/nginx-php-fastcgi-howto/

#
# This script is started once and receives PHP requests from Nginx for 
# all apps. The Nginx config passes the full path to the script being requested, so
# only one fastcgi runner is needed for all apps, virtual hosts, etc.
#
# See also the init.d script for starting this on boot.
#
# To install PHP, I had to also compile the following:
#
#   * http://www.gnu.org/software/m4/
#   * http://flex.sourceforge.net/
#   * http://php.net/ with './configure --prefix=/usr/local --enable-fastcgi'

## ABSOLUTE path to the PHP binary
PHPFCGI="/usr/local/bin/php"

## tcp-port to bind on
FCGIPORT="9000"

## IP to bind on
FCGIADDR="127.0.0.1"

## number of PHP children to spawn
PHP_FCGI_CHILDREN=5

## number of request before php-process will be restarted
PHP_FCGI_MAX_REQUESTS=1000

# allowed environment variables sperated by spaces
ALLOWED_ENV="PATH USER"

## if this script is run as root switch to the following user
USERID=deploy
