			Name of pool. Used in logs and stats.			default			Address to accept fastcgi requests on.			Valid syntax is 'ip.ad.re.ss:port' or just 'port' or '/path/to/unix/socket'			127.0.0.1:9000 							Set listen(2) backlog				-1				Set permissions for unix socket, if one used.				In Linux read/write permissions must be set in order to allow connections from web server.				Many BSD-derrived systems allow connections regardless of permissions.				  				   				0666						Additional php.ini defines, specific to this pool of workers.													Unix user of processes					Unix group of processes					Process manager settings							Sets style of controling worker process count.				Valid values are 'static' and 'apache-like'				static				Sets the limit on the number of simultaneous requests that will be served.				Equivalent to Apache MaxClients directive.				Equivalent to PHP_FCGI_CHILDREN environment in original php.fcgi				Used with any pm_style.				5 				Settings group for 'apache-like' pm style									Sets the number of server processes created on startup.					Used only when 'apache-like' pm_style is selected					20					Sets the desired minimum number of idle server processes.					Used only when 'apache-like' pm_style is selected					5					Sets the desired maximum number of idle server processes.					Used only when 'apache-like' pm_style is selected					35										The timeout (in seconds) for serving a single request after which the worker process will be terminated			Should be used when 'max_execution_time' ini option does not stop script execution for some reason			'0s' means 'off'			0s			The timeout (in seconds) for serving of single request after which a php backtrace will be dumped to slow.log file			'0s' means 'off'			0s			The log file for slow requests			logs/slow.log			Set open file desc rlimit			1024                        			Set max core size rlimit			0			Chroot to this directory at the start, absolute path						Chdir to this directory at the start, absolute path						Redirect workers' stdout and stderr into main error log.			If not set, they will be redirected to /dev/null, according to FastCGI specs			yes			How much requests each process should execute before respawn.			Useful to work around memory leaks in 3rd party libraries.			For endless request processing please specify 0			Equivalent to PHP_FCGI_MAX_REQUESTS			500			Comma separated list of ipv4 addresses of FastCGI clients that allowed to connect.			Equivalent to FCGI_WEB_SERVER_ADDRS environment in original php.fcgi (5.2.2+)			Makes sense only with AF_INET listening socket.			127.0.0.1                                      			Pass environment variables like LD_LIBRARY_PATH			All $VARIABLEs are taken from current environment							$HOSTNAME				/usr/local/bin:/usr/bin:/bin				/tmp				/tmp				/tmp				$OSTYPE				$MACHTYPE				2
