<workers>

<section name="pool">

Name of pool. Used in logs and stats.
<value name="name">default</value>

Address to accept fastcgi requests on.
Valid syntax is 'ip.ad.re.ss:port' or just 'port' or '/path/to/unix/socket'
<value name="listen_address">127.0.0.1:9000</value>

<value name="listen_options">

Set listen(2) backlog
<value name="backlog">-1</value>

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.

Unix user of processes
<value name="user">www</value>

Unix group of processes
<value name="group">www</value>

Process manager settings
<value name="pm">

Sets style of controling worker process count.
Valid values are 'static' and 'apache-like'
<value name="style">static</value>

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.
<value name="max_children">5</value>

Settings group for 'apache-like' pm style
<value name="apache_like">

Sets the number of server processes created on startup.
Used only when 'apache-like' pm_style is selected

</value>

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'
<value name="request_terminate_timeout">0s</value>

The timeout (in seconds) for serving of single request after which a php backtrace will be dumped to slow.log file

Redirect workers' stdout and stderr into main error log.
If not set, they will be redirected to /dev/null, according to FastCGI specs
<value name="catch_workers_output">yes</value>

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

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+)
