+; FPM Configuration ;
+;;;;;;;;;;;;;;;;;;;;;
+
+; All relative paths in this configuration file are relative to PHP's install
+; prefix (/usr). This prefix can be dynamicaly changed by using the
+; '-p' argument from the command line.
+
+; Include one or more files. If glob(3) exists, it is used to include a bunch of
+; files from a glob(3) pattern. This directive can be used everywhere in the
+; file.
+; Relative path can also be used. They will be prefixed by:
+;  - the global prefix if it's been set (-p arguement)
+;  - /usr otherwise
+;include=/etc/php5/fpm/*.conf

+; Note: the default prefix is /var
+; Default Value: none
+pid = /var/run/php5-fpm-custom.pid
+
+; Error log file
+; If it's set to "syslog", log is sent to syslogd instead of being written
+; in a local file.
+; Note: the default prefix is /var
+; Default Value: log/php-fpm.log
+error_log = syslog
+
+; syslog_facility is used to specify what type of program is logging the
+; message. This lets syslogd specify that messages from different facilities
+; will be handled differently.
+; See syslog(3) for possible values (ex daemon equiv LOG_DAEMON)
+; Default Value: daemon
+;syslog.facility = daemon
+
+; syslog_ident is prepended to every message. If you have multiple FPM
+; instances running on the same server, you can change the default value
+; which must suit common needs.
+; Default Value: php-fpm
+;syslog.ident = php-fpm
+
+; Log level
+; Possible Values: alert, error, warning, notice, debug
+; Default Value: notice
+log_level = warning
+
+; If this number of child processes exit with SIGSEGV or SIGBUS within the time
+; interval set by emergency_restart_interval then FPM will restart. A value
+; of '0' means 'Off'.
+; Default Value: 0
+emergency_restart_threshold = 100
+
+; Interval of time used by emergency_restart_interval to determine when·
+; a graceful restart will be initiated.  This can be useful to work around
+; accidental corruptions in an accelerator's shared memory.

+
+; The maximum number of processes FPM will fork. This has been design to control
+; the global number of processes when using dynamic PM within a lot of pools.
+; Use it with caution.
+; Note: A value of 0 indicates no limit
+; Default Value: 0
+; process.max = 128
+
+; Send FPM to background. Set to 'no' to keep FPM in foreground for debugging.

+;;;;;;;;;;;;;;;;;;;;
+; Pool Definitions ;·
+;;;;;;;;;;;;;;;;;;;;
+
+; Multiple pools of child processes may be started with different listening
+; ports and different management options.  The name of the pool will be
+; used in logs and stats. There is no limitation on the number of pools which
+; FPM can handle. Your system will tell you anyway :)
+
+; Start a new pool named 'www'.
+; the variable $pool can we used in any directive and will be replaced by the
+; pool name ('www' here)
+
+{% for num in range(0, fpm_pool_count, 1) %}
+[www{{ num }}]
+
+; Per pool prefix
+; It only applies on the following directives:
+; - 'slowlog'
+; - 'listen' (unixsocket)
+; - 'chroot'
+; - 'chdir'
+; - 'php_values'
+; - 'php_admin_values'
+; When not set, the global prefix (or /usr) applies instead.
+; Note: This directive can also be relative to the global prefix.
+; Default Value: none
+;prefix = /path/to/pools/$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.
+user = www-data
+group = www-data
+
+; 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 address on
+;                            a specific port;
+;   'port'                 - to listen on a TCP socket to all addresses on a
+;                            specific port;
+;   '/path/to/unix/socket' - to listen on a unix socket.
+; Note: This value is mandatory.
+listen = /var/run/php5-fpm-pool-$pool.sock
+
+; Set listen(2) backlog.
+; Default Value: 128 (-1 on FreeBSD and OpenBSD)
+listen.backlog = 8192
+
+; 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. Many
+; BSD-derived systems allow connections regardless of permissions. 
+; Default Values: user and group are set as the running user
+;                 mode is set to 0666
+;listen.owner = www-data
+;listen.group = www-data
+;listen.mode = 0666
+ 
+; List of ipv4 addresses of FastCGI clients which are allowed to connect.
+; Equivalent to the FCGI_WEB_SERVER_ADDRS environment variable in the original
+; PHP FCGI (5.2.2+). Makes sense only with a tcp listening socket. Each address
+; must be separated by a comma. If this value is left blank, connections will be
+; accepted from any ip address.
+; Default Value: any
+;listen.allowed_clients = 127.0.0.1
+
+; 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.
+;             pm.min_spare_servers - the minimum number of children in 'idle'
+;                                    state (waiting to process). If the number
+;                                    of 'idle' processes is less than this
+;                                    number then some children will be created.
+;             pm.max_spare_servers - the maximum number of children in 'idle'
+;                                    state (waiting to process). If the number
+;                                    of 'idle' processes is greater than this
+;                                    number then some children will be killed.
+;  ondemand - no children are created at startup. Children will be forked when
+;             new requests will connect. The following parameter are used:
+;             pm.max_children           - the maximum number of children that
+;                                         can be alive at the same time.
+;             pm.process_idle_timeout   - The number of seconds after which
+;                                         an idle process will be killed.
+; Note: This value is mandatory.
+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.
+; Note: Used only when pm is set to 'dynamic'
+; Default Value: min_spare_servers + (max_spare_servers - min_spare_servers) / 2
+pm.start_servers = 15
+
+; The desired minimum number of idle server processes.
+; Note: Used only when pm is set to 'dynamic'
+; Note: Mandatory when pm is set to 'dynamic'
+pm.min_spare_servers = 5
+
+; The desired maximum number of idle server processes.
+; Note: Used only when pm is set to 'dynamic'
+; Note: Mandatory when pm is set to 'dynamic'
+pm.max_spare_servers = 30
+
+; 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.
+; This can be useful to work around memory leaks in 3rd party libraries. For
+; endless request processing specify '0'. Equivalent to PHP_FCGI_MAX_REQUESTS.
+; Default Value: 0
+pm.max_requests = 100
+
+; 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;
+;   start since          - number of seconds since FPM has started;
+;   accepted conn        - the number of request accepted by the pool;
+;   listen queue         - the number of request in the queue of pending
+;                          connections (see backlog in listen(2));
+;   max listen queue     - the maximum number of requests in the queue
+;                          of pending connections since FPM has started;
+;   listen queue len     - the size of the socket queue of pending connections;
+;   idle processes       - the number of idle processes;
+;   active processes     - the number of active processes;
+;   total processes      - the number of idle + active processes;
+;   max active processes - the maximum number of active processes since 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:
+;   pool:                 www
+;   process manager:      static
+;   start time:           01/Jul/2011:17:53:49 +0200

+;   active processes:     11
+;   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
+; The Full status returns for each process:
+;   pid                  - the PID of the process;
+;   state                - the state of the process (Idle, Running, ...);
+;   start time           - the date and time the process has started;
+;   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.

+; be killed. This option should be used when the 'max_execution_time' ini option
+; does not stop script execution for some reason. A value of '0' means 'off'.
+; Available units: s(econds)(default), m(inutes), h(ours), or d(ays)
+; Default Value: 0
+;request_terminate_timeout = 0
+ 
+; Set open file descriptor rlimit.
+; Default Value: system defined value
+rlimit_files = 262144
+ 
+; Set max core size rlimit.
+; Possible Values: 'unlimited' or an integer greater or equal to 0
+; Default Value: system defined value
+;rlimit_core = 0
+ 
+; Chroot to this directory at the start. This value must be defined as an
+; absolute path. When this value is not set, chroot is not used.
+; Note: you can prefix with '$prefix' to chroot to the pool prefix or one
+; of its subdirectories. If the pool prefix is not set, the global prefix
+; will be used instead.
+; Note: chrooting is a great security feature and should be used whenever 
+;       possible. However, all PHP paths will be relative to the chroot
+;       (error_log, sessions.save_path, ...).
+; Default Value: not set
+;chroot = 
+ 
+; Chdir to this directory at the start.
+; Note: relative path can be used.
+; Default Value: current directory or / when chroot
+chdir = /
+ 
+; Redirect worker stdout and stderr into main error log. If not set, stdout and
+; stderr will be redirected to /dev/null according to FastCGI specs.
+; Note: on highloaded environement, this can cause some delay in the page
+; process time (several ms).
+; Default Value: no
+catch_workers_output = yes
+
+; 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
+; exectute php code.
+; Note: set an empty value to allow all extensions.
+; Default Value: .php
+;security.limit_extensions = .php .php3 .php4 .php5
+ 
+; Pass environment variables like LD_LIBRARY_PATH. All $VARIABLEs are taken from
+; the current environment.
+; Default Value: clean env
+;env[HOSTNAME] = $HOSTNAME
+;env[PATH] = /usr/local/bin:/usr/bin:/bin
+;env[TMP] = /tmp
+;env[TMPDIR] = /tmp
+;env[TEMP] = /tmp
+
+; 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 /usr)
+
+
+; Default Value: nothing is defined by default except the values in php.ini and
+;                specified at startup with the -d argument
