All relative paths in this config are relative to php's install prefix
Pid file
Error log file
Log level
When this amount of php processes exited with SIGSEGV or SIGBUS ...
... in a less than this interval of time, a graceful restart will be initiated.
Useful to work around accidental curruptions in accelerator's shared memory.
Time limit on waiting child's reaction on signals from master
Set to 'no' to debug fpm
Name of pool. Used in logs and stats.
Address to accept fastcgi requests on.
Valid syntax is 'ip.ad.re.ss:port' or just 'port' or '/path/to/unix/socket'
Set listen(2) backlog
Set permissions for unix socket, if one used.
In Linux read/write permissions must be set in order to allow connections from web server.
Many BSD-derrived systems allow connections regardless of permissions.
Additional php.ini defines, specific to this pool of workers.
↑ 如果安装 Nginx + PHP 用于程序调试，则此处应设置为"1"以显示PHP错误信息，设置为"0" Nginx 会报状态为500的空白错误页
Unix user of processes
Unix group of processes
Process manager settings
Sets style of controling worker process count.
Valid values are 'static' and 'apache-like'
Sets the limit on the number of simultaneous requests that will be served.
Equivalent to Apache MaxClients directive.
Equivalent to PHP_FCGI_CHILDREN environment in original php.fcgi
Used with any pm_style.
↑ 进程数为64，如果服务器内存大于3GB，可以只开启128-200个进程
Settings group for 'apache-like' pm style
Sets the number of server processes created on startup.
Used only when 'apache-like' pm_style is selected
Sets the desired minimum number of idle server processes.
Used only when 'apache-like' pm_style is selected
Sets the desired maximum number of idle server processes.
Used only when 'apache-like' pm_style is selected
The timeout (in seconds) for serving a single request after which the worker process will be terminated
Should be used when 'max_execution_time' ini option does not stop script execution for some reason
'0s' means 'off'
The timeout (in seconds) for serving of single request after which a php backtrace will be dumped to slow.log file
'0s' means 'off'
The log file for slow requests
Set open file desc rlimit
Set max core size rlimit
Chroot to this directory at the start, absolute path
Chdir to this directory at the start, absolute path
Redirect workers' stdout and stderr into main error log.
If not set, they will be redirected to /dev/null, according to FastCGI specs
How much requests each process should execute before respawn.
Useful to work around memory leaks in 3rd party libraries.
For endless request processing please specify 0
Equivalent to PHP_FCGI_MAX_REQUESTS
Comma separated list of ipv4 addresses of FastCGI clients that allowed to connect.
Equivalent to FCGI_WEB_SERVER_ADDRS environment in original php.fcgi (5.2.2+)
Makes sense only with AF_INET listening socket.
Pass environment variables like LD_LIBRARY_PATH
All $VARIABLEs are taken from current environment
