-; Start a new pool named 'www'.
-; the variable $pool can be used in any directive and will be replaced by the
-; pool name ('www' here)
-[www]

-; - 'listen' (unixsocket)
-; - 'chroot'
-; - 'chdir'
-; - 'php_values'
-; - 'php_admin_values'
-; When not set, the global prefix (or @php_fpm_prefix@) applies instead.
-; Note: This directive can also be relative to the global prefix.
-; Default Value: none
-;prefix = /path/to/pools/$pool
-
-; Unix user/group of processes
-; Note: The user is mandatory. If the group is not set, the default user's group
-;       will be used.
-; RPM: apache user chosen to provide access to the same directories as httpd
-user = apache
-; RPM: Keep a group allowed to write in log dir.
-group = apache
-
-; The address on which to accept FastCGI requests.
-; Valid syntaxes are:
-;   'ip.add.re.ss:port'    - to listen on a TCP socket to a specific IPv4 address on

-listen = /run/php-fpm.sock
-
-; Set listen(2) backlog.
-; Default Value: 511
-;listen.backlog = 511
-
-; Set permissions for unix socket, if one is used. In Linux, read/write
-; permissions must be set in order to allow connections from a web server.
-; Default Values: user and group are set as the running user

-; Default Value: any
-listen.allowed_clients = 127.0.0.1
-
-; Specify the nice(2) priority to apply to the pool processes (only if set)
-; The value can vary from -19 (highest priority) to 20 (lower priority)
-; Note: - It will only work if the FPM master process is launched as root
-;       - The pool processes will inherit the master process priority

-; Default Value: no set
-; process.priority = -19
-
-; Set the process dumpable flag (PR_SET_DUMPABLE prctl) even if the process user

-
-; Choose how the process manager will control the number of child processes.
-; Possible Values:
-;   static  - a fixed number (pm.max_children) of child processes;
-;   dynamic - the number of child processes are set dynamically based on the
-;             following directives. With this process management, there will be
-;             always at least 1 children.
-;             pm.max_children      - the maximum number of children that can
-;                                    be alive at the same time.
-;             pm.start_servers     - the number of children created on startup.

-;                                    state (waiting to process). If the number

-;  ondemand - no children are created at startup. Children will be forked when

-pm = dynamic
-
-; The number of child processes to be created when pm is set to 'static' and the
-; maximum number of child processes when pm is set to 'dynamic' or 'ondemand'.
-; This value sets the limit on the number of simultaneous requests that will be
-; served. Equivalent to the ApacheMaxClients directive with mpm_prefork.
-; Equivalent to the PHP_FCGI_CHILDREN environment variable in the original PHP
-; CGI. The below defaults are based on a server without much resources. Don't
-; forget to tweak pm.* to fit your needs.
-; Note: Used when pm is set to 'static', 'dynamic' or 'ondemand'
-; Note: This value is mandatory.
-pm.max_children = 50
-
-; The number of child processes created on startup.

-
-; The number of seconds after which an idle process will be killed.
-; Note: Used only when pm is set to 'ondemand'
-; Default Value: 10s
-;pm.process_idle_timeout = 10s;
-
-; The number of requests each child process should execute before respawning.

-; endless request processing specify '0'. Equivalent to PHP_FCGI_MAX_REQUESTS.
-; Default Value: 0
-;pm.max_requests = 500
-
-; The URI to view the FPM status page. If this value is not set, no URI will be
-; recognized as a status page. It shows the following informations:
-;   pool                 - the name of the pool;
-;   process manager      - static, dynamic or ondemand;
-;   start time           - the date and time FPM has started;

-;   max children reached - number of times, the process limit has been reached,
-;                          when pm tries to start more children (works only for
-;                          pm 'dynamic' and 'ondemand');
-; Value are updated in real time.
-; Example output:

-;   process manager:      static
-;   start time:           01/Jul/2011:17:53:49 +0200

-;   total processes:      15
-;   max active processes: 12
-;   max children reached: 0
-;
-; By default the status page output is formatted as text/plain. Passing either
-; 'html', 'xml' or 'json' in the query string will return the corresponding
-; output syntax. Example:
-;   http://www.foo.bar/status
-;   http://www.foo.bar/status?json
-;   http://www.foo.bar/status?html
-;   http://www.foo.bar/status?xml
-;
-; By default the status page only outputs short status. Passing 'full' in the
-; query string will also return status for each pool process.
-; Example:
-;   http://www.foo.bar/status?full
-;   http://www.foo.bar/status?json&full
-;   http://www.foo.bar/status?html&full
-;   http://www.foo.bar/status?xml&full

-;   start since          - the number of seconds since the process has started;
-;   requests             - the number of requests the process has served;
-;   request duration     - the duration in µs of the requests;
-;   request method       - the request method (GET, POST, ...);
-;   request URI          - the request URI with the query string;
-;   content length       - the content length of the request (only with POST);
-;   user                 - the user (PHP_AUTH_USER) (or '-' if not set);
-;   script               - the main script called (or '-' if not set);
-;   last request cpu     - the %cpu the last request consumed
-;                          it's always 0 if the process is not in Idle state
-;                          because CPU calculation is done when the request
-;                          processing has terminated;
-;   last request memory  - the max amount of memory the last request consumed
-;                          it's always 0 if the process is not in Idle state
-;                          because memory calculation is done when the request
-;                          processing has terminated;
-; If the process is in Idle state, then informations are related to the
-; last request the process has served. Otherwise informations are related to
-; the current request being served.

-
-; The ping URI to call the monitoring page of FPM. If this value is not set, no
-; URI will be recognized as a ping page. This could be used to test from outside
-; that FPM is alive and responding, or to
-; - create a graph of FPM availability (rrd or such);
-; - remove a server from a group if it is not responding (load balancing);
-; - trigger alerts for the operating team (24/7).
-; Note: The value must start with a leading slash (/). The value can be

-; via getenv(), $_ENV and $_SERVER.
-; Default Value: yes
-;clear_env = no
-
-; Limits the extensions of the main script FPM will allow to parse. This can
-; prevent configuration mistakes on the web server side. You should only limit
-; FPM to .php extensions to prevent malicious users to use other extensions to

-
-; Additional php.ini defines, specific to this pool of workers. These settings
-; overwrite the values previously defined in the php.ini. The directives are the
-; same as the PHP SAPI:
-;   php_value/php_flag             - you can set classic ini defines which can
-;                                    be overwritten from PHP call 'ini_set'.
-;   php_admin_value/php_admin_flag - these directives won't be overwritten by
-;                                     PHP call 'ini_set'
-; For php_*flag, valid values are on, off, 1, 0, true, false, yes or no.
-
-; Defining 'extension' will load the corresponding shared extension from
-; extension_dir. Defining 'disable_functions' or 'disable_classes' will not
-; overwrite previously defined php.ini values, but will append the new value
-; instead.
-
-; Note: path INI options can be relative and will be expanded with the prefix
-; (pool, global or @prefix@)
-
-; Default Value: nothing is defined by default except the values in php.ini and
-;                specified at startup with the -d argument
