+; FPM Configuration ;
+;;;;;;;;;;;;;;;;;;;;;
+
+; All relative paths in this configuration file are relative to PHP's install
+; prefix (/usr). This prefix can be dynamically changed by using the
+; '-p' argument from the command line.

+; Global Options ;
+;;;;;;;;;;;;;;;;;;
+
+[global]
+; Pid file
+; Note: the default prefix is /var
+; Default Value: none
+pid = /run/php/php7.4-fpm.pid
+
+; Error log file
+; If it's set to "syslog", log is sent to syslogd instead of being written
+; into a local file.
+; Note: the default prefix is /var
+; Default Value: log/php-fpm.log
+error_log = /var/log/php7.4-fpm.log
+
+; 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 = notice
+
+; 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 = 0
+
+; 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.
+; Available Units: s(econds), m(inutes), h(ours), or d(ays)
+; Default Unit: seconds
+; Default Value: 0
+;emergency_restart_interval = 0
+
+; Time limit for child processes to wait for a reaction on signals from master.
+; Available units: s(econds), m(inutes), h(ours), or d(ays)

+; Default Value: 0
+;process_control_timeout = 0
+
+; The maximum number of processes FPM will fork. This has been designed 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
+
+; Specify the nice(2) priority to apply to the master process (only if set)
+; The value can vary from -19 (highest priority) to 20 (lowest priority)
+; Note: - It will only work if the FPM master process is launched as root
+;       - The pool process will inherit the master process priority
+;         unless specified otherwise
+; Default Value: no set
+; process.priority = -19
+
+; Send FPM to background. Set to 'no' to keep FPM in foreground for debugging.
+; Default Value: yes
+;daemonize = yes
+
+; Set open file descriptor rlimit for the master process.
+; Default Value: system defined value
+;rlimit_files = 1024
+
+; Set max core size rlimit for the master process.
+; Possible Values: 'unlimited' or an integer greater or equal to 0
+; Default Value: system defined value
+;rlimit_core = 0
+
+; Specify the event mechanism FPM will use. The following is available:
+; - select     (any POSIX os)
+; - poll       (any POSIX os)
+; - epoll      (linux >= 2.5.44)
+; - kqueue     (FreeBSD >= 4.1, OpenBSD >= 2.9, NetBSD >= 2.0)
+; - /dev/poll  (Solaris >= 7)
+; - port       (Solaris >= 10)
+; Default Value: not set (auto detection)
+;events.mechanism = epoll
+
+; When FPM is built with systemd integration, specify the interval,
+; in seconds, between health report notification to systemd.
+; Set to 0 to disable.
+; Available Units: s(econds), m(inutes), h(ours)
+; Default Unit: seconds
+; Default value: 10

+; 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 :)
+
+; 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 argument)
