1; Start a new pool named 'www'.
2; the variable $pool can be used in any directive and will be replaced by the
3; pool name ('www' here)
4[www]
5
6; Per pool prefix
7; It only applies on the following directives:
8; - 'access.log'
9; - 'slowlog'
10; - 'listen' (unixsocket)
11; - 'chroot'
12; - 'chdir'
13; - 'php_values'
14; - 'php_admin_values'
15; When not set, the global prefix (or @php_fpm_prefix@) applies instead.
16; Note: This directive can also be relative to the global prefix.
17; Default Value: none
18;prefix = /path/to/pools/$pool
19
20; Unix user/group of processes
21; Note: The user is mandatory. If the group is not set, the default user's group
22;       will be used.
23user = @php_fpm_user@
24group = @php_fpm_group@
25
26; The address on which to accept FastCGI requests.
27; Valid syntaxes are:
28;   'ip.add.re.ss:port'    - to listen on a TCP socket to a specific IPv4 address on
29;                            a specific port;
30;   '[ip:6:addr:ess]:port' - to listen on a TCP socket to a specific IPv6 address on
31;                            a specific port;
32;   'port'                 - to listen on a TCP socket to all addresses
33;                            (IPv6 and IPv4-mapped) on a specific port;

35; Note: This value is mandatory.
36listen = 127.0.0.1:9000
37
38; Set listen(2) backlog.
39; Default Value: 511 (-1 on FreeBSD and OpenBSD)
40;listen.backlog = 511
41
42; Set permissions for unix socket, if one is used. In Linux, read/write
43; permissions must be set in order to allow connections from a web server. Many
44; BSD-derived systems allow connections regardless of permissions. The owner
45; and group can be specified either by name or by their numeric IDs.
46; Default Values: user and group are set as the running user
47;                 mode is set to 0660
48;listen.owner = @php_fpm_user@
49;listen.group = @php_fpm_group@
50;listen.mode = 0660
51; When POSIX Access Control Lists are supported you can set them using
52; these options, value is a comma separated list of user/group names.
53; When set, listen.owner and listen.group are ignored
54;listen.acl_users =
55;listen.acl_groups =
56
57; List of addresses (IPv4/IPv6) of FastCGI clients which are allowed to connect.
58; Equivalent to the FCGI_WEB_SERVER_ADDRS environment variable in the original
59; PHP FCGI (5.2.2+). Makes sense only with a tcp listening socket. Each address
60; must be separated by a comma. If this value is left blank, connections will be
61; accepted from any ip address.
62; Default Value: any
63;listen.allowed_clients = 127.0.0.1
64
65; Specify the nice(2) priority to apply to the pool processes (only if set)
66; The value can vary from -19 (highest priority) to 20 (lower priority)
67; Note: - It will only work if the FPM master process is launched as root
68;       - The pool processes will inherit the master process priority
69;         unless it specified otherwise
70; Default Value: no set
71; process.priority = -19
72
73; Set the process dumpable flag (PR_SET_DUMPABLE prctl) even if the process user
74; or group is different than the master process user. It allows to create process
75; core dump and ptrace the process for the pool user.
76; Default Value: no
77; process.dumpable = yes
78
79; Choose how the process manager will control the number of child processes.
80; Possible Values:
81;   static  - a fixed number (pm.max_children) of child processes;
82;   dynamic - the number of child processes are set dynamically based on the
83;             following directives. With this process management, there will be
84;             always at least 1 children.
85;             pm.max_children      - the maximum number of children that can
86;                                    be alive at the same time.
87;             pm.start_servers     - the number of children created on startup.
88;             pm.min_spare_servers - the minimum number of children in 'idle'
89;                                    state (waiting to process). If the number
90;                                    of 'idle' processes is less than this
91;                                    number then some children will be created.
92;             pm.max_spare_servers - the maximum number of children in 'idle'
93;                                    state (waiting to process). If the number
94;                                    of 'idle' processes is greater than this
95;                                    number then some children will be killed.
96;  ondemand - no children are created at startup. Children will be forked when
97;             new requests will connect. The following parameter are used:
98;             pm.max_children           - the maximum number of children that
99;                                         can be alive at the same time.
100;             pm.process_idle_timeout   - The number of seconds after which
101;                                         an idle process will be killed.
102; Note: This value is mandatory.
103pm = dynamic
104
105; The number of child processes to be created when pm is set to 'static' and the
106; maximum number of child processes when pm is set to 'dynamic' or 'ondemand'.
107; This value sets the limit on the number of simultaneous requests that will be
108; served. Equivalent to the ApacheMaxClients directive with mpm_prefork.
109; Equivalent to the PHP_FCGI_CHILDREN environment variable in the original PHP
110; CGI. The below defaults are based on a server without much resources. Don't
111; forget to tweak pm.* to fit your needs.
112; Note: Used when pm is set to 'static', 'dynamic' or 'ondemand'
113; Note: This value is mandatory.

119pm.start_servers = 2
120
121; The desired minimum number of idle server processes.
122; Note: Used only when pm is set to 'dynamic'
123; Note: Mandatory when pm is set to 'dynamic'
124pm.min_spare_servers = 1
125
126; The desired maximum number of idle server processes.
127; Note: Used only when pm is set to 'dynamic'
128; Note: Mandatory when pm is set to 'dynamic'
129pm.max_spare_servers = 3
130
131; The number of seconds after which an idle process will be killed.
132; Note: Used only when pm is set to 'ondemand'
133; Default Value: 10s
134;pm.process_idle_timeout = 10s;
135
136; The number of requests each child process should execute before respawning.
137; This can be useful to work around memory leaks in 3rd party libraries. For
138; endless request processing specify '0'. Equivalent to PHP_FCGI_MAX_REQUESTS.
139; Default Value: 0
140;pm.max_requests = 500
141
142; The URI to view the FPM status page. If this value is not set, no URI will be
143; recognized as a status page. It shows the following information:
144;   pool                 - the name of the pool;
145;   process manager      - static, dynamic or ondemand;

157;   max active processes - the maximum number of active processes since FPM
158;                          has started;
159;   max children reached - number of times, the process limit has been reached,
160;                          when pm tries to start more children (works only for
161;                          pm 'dynamic' and 'ondemand');
162; Value are updated in real time.
163; Example output:
164;   pool:                 www
165;   process manager:      static
166;   start time:           01/Jul/2011:17:53:49 +0200
167;   start since:          62636
168;   accepted conn:        190460

175;   max active processes: 12
176;   max children reached: 0
177;
178; By default the status page output is formatted as text/plain. Passing either
179; 'html', 'xml' or 'json' in the query string will return the corresponding
180; output syntax. Example:
181;   http://www.foo.bar/status
182;   http://www.foo.bar/status?json
183;   http://www.foo.bar/status?html
184;   http://www.foo.bar/status?xml
185;
186; By default the status page only outputs short status. Passing 'full' in the
187; query string will also return status for each pool process.
188; Example:
189;   http://www.foo.bar/status?full
190;   http://www.foo.bar/status?json&full
191;   http://www.foo.bar/status?html&full
192;   http://www.foo.bar/status?xml&full
193; The Full status returns for each process:
194;   pid                  - the PID of the process;
195;   state                - the state of the process (Idle, Running, ...);
196;   start time           - the date and time the process has started;

200;   request method       - the request method (GET, POST, ...);
201;   request URI          - the request URI with the query string;
202;   content length       - the content length of the request (only with POST);
203;   user                 - the user (PHP_AUTH_USER) (or '-' if not set);
204;   script               - the main script called (or '-' if not set);
205;   last request cpu     - the %cpu the last request consumed
206;                          it's always 0 if the process is not in Idle state
207;                          because CPU calculation is done when the request
208;                          processing has terminated;
209;   last request memory  - the max amount of memory the last request consumed
210;                          it's always 0 if the process is not in Idle state
211;                          because memory calculation is done when the request
212;                          processing has terminated;
213; If the process is in Idle state, then informations are related to the
214; last request the process has served. Otherwise informations are related to
215; the current request being served.
216; Example output:

233;       It's available in: @EXPANDED_DATADIR@/fpm/status.html
234;
235; Note: The value must start with a leading slash (/). The value can be
236;       anything, but it may not be a good idea to use the .php extension or it

238; Default Value: not set
239;pm.status_path = /status
240
241; The address on which to accept FastCGI status request. This creates a new

245;
246; Valid syntaxes are:
247;   'ip.add.re.ss:port'    - to listen on a TCP socket to a specific IPv4 address on

255;pm.status_listen = 127.0.0.1:9001
256
257; The ping URI to call the monitoring page of FPM. If this value is not set, no
258; URI will be recognized as a ping page. This could be used to test from outside
259; that FPM is alive and responding, or to
260; - create a graph of FPM availability (rrd or such);
261; - remove a server from a group if it is not responding (load balancing);
262; - trigger alerts for the operating team (24/7).
263; Note: The value must start with a leading slash (/). The value can be
264;       anything, but it may not be a good idea to use the .php extension or it
