6; prefix (@prefix@). This prefix can be dynamically changed by using the
7; '-p' argument from the command line.

13[global]
14; Pid file
15; Note: the default prefix is @EXPANDED_LOCALSTATEDIR@
16; Default Value: none
17;pid = run/php-fpm.pid
18
19; Error log file
20; If it's set to "syslog", log is sent to syslogd instead of being written
21; into a local file.
22; Note: the default prefix is @EXPANDED_LOCALSTATEDIR@
23; Default Value: log/php-fpm.log
24;error_log = log/php-fpm.log
25
26; syslog_facility is used to specify what type of program is logging the
27; message. This lets syslogd specify that messages from different facilities
28; will be handled differently.
29; See syslog(3) for possible values (ex daemon equiv LOG_DAEMON)
30; Default Value: daemon
31;syslog.facility = daemon
32
33; syslog_ident is prepended to every message. If you have multiple FPM
34; instances running on the same server, you can change the default value
35; which must suit common needs.
36; Default Value: php-fpm
37;syslog.ident = php-fpm
38
39; Log level
40; Possible Values: alert, error, warning, notice, debug
41; Default Value: notice
42;log_level = notice
43
44; If this number of child processes exit with SIGSEGV or SIGBUS within the time
45; interval set by emergency_restart_interval then FPM will restart. A value
46; of '0' means 'Off'.
47; Default Value: 0
48;emergency_restart_threshold = 0
49
50; Interval of time used by emergency_restart_interval to determine when
51; a graceful restart will be initiated.  This can be useful to work around
52; accidental corruptions in an accelerator's shared memory.
53; Available Units: s(econds), m(inutes), h(ours), or d(ays)
54; Default Unit: seconds
55; Default Value: 0
56;emergency_restart_interval = 0
57
58; Time limit for child processes to wait for a reaction on signals from master.
59; Available units: s(econds), m(inutes), h(ours), or d(ays)
60; Default Unit: seconds
61; Default Value: 0
62;process_control_timeout = 0
63
64; The maximum number of processes FPM will fork. This has been designed to control
65; the global number of processes when using dynamic PM within a lot of pools.
66; Use it with caution.
67; Note: A value of 0 indicates no limit
68; Default Value: 0
69; process.max = 128
70
71; Specify the nice(2) priority to apply to the master process (only if set)
72; The value can vary from -19 (highest priority) to 20 (lowest priority)
73; Note: - It will only work if the FPM master process is launched as root
74;       - The pool process will inherit the master process priority
75;         unless specified otherwise
76; Default Value: no set
77; process.priority = -19
78
79; Send FPM to background. Set to 'no' to keep FPM in foreground for debugging.
80; Default Value: yes
81;daemonize = yes
82
83; Set open file descriptor rlimit for the master process.
84; Default Value: system defined value
85;rlimit_files = 1024
86
87; Set max core size rlimit for the master process.
88; Possible Values: 'unlimited' or an integer greater or equal to 0
89; Default Value: system defined value
90;rlimit_core = 0
91
92; Specify the event mechanism FPM will use. The following is available:
93; - select     (any POSIX os)
94; - poll       (any POSIX os)
95; - epoll      (linux >= 2.5.44)
96; - kqueue     (FreeBSD >= 4.1, OpenBSD >= 2.9, NetBSD >= 2.0)
97; - /dev/poll  (Solaris >= 7)
98; - port       (Solaris >= 10)
99; Default Value: not set (auto detection)
100;events.mechanism = epoll
101
102; When FPM is built with systemd integration, specify the interval,
103; in seconds, between health report notification to systemd.
104; Set to 0 to disable.
105; Available Units: s(econds), m(inutes), h(ours)
106; Default Unit: seconds
107; Default value: 10
108;systemd_interval = 10

111; Pool Definitions ;
112;;;;;;;;;;;;;;;;;;;;
113
114; Multiple pools of child processes may be started with different listening
115; ports and different management options.  The name of the pool will be
116; used in logs and stats. There is no limitation on the number of pools which
117; FPM can handle. Your system will tell you anyway :)
118
119; Include one or more files. If glob(3) exists, it is used to include a bunch of
120; files from a glob(3) pattern. This directive can be used everywhere in the
121; file.
122; Relative path can also be used. They will be prefixed by:
123;  - the global prefix if it's been set (-p argument)
124;  - @prefix@ otherwise
