PHP-FPM包的安装与配置 转

实验环境：CentOS7

[root@~ localhost]#yum -y install php-fpm
php-fpm包：用于将php运行于fpm模式

#在安装php-fpm时，一般同时安装如下包
[root@~ localhost]#yum -y install php-mbstring php-mcrypt php-mysql

; Start a new pool named 'www'.
[www]
; Note: This value is mandatory.
listen = 127.0.0.1:9000　　　　#监听本地的ip和端口；
 
; Set listen(2) backlog. A value of '-1' means unlimited.
; Default Value: -1

;listen.backlog = -1　　　　　　#后援队列：当请求数大于并发数时，设置排队等待的请求数；-1表示无限制

listen.allowed_clients = 127.0.0.1  #授权设置，允许那些主机可以连接本服务主机;若httpd在别的主机，则需要修改

user = apache　　　　　　　　#运行进程的用户
; RPM: Keep a group allowed to write in log dir.
group = apache　　　　　　　　#运行进程的组

#运行子进程的方式：static 静态方式 和dynamic 动态方式

; 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:
; pm.max_children - the maximum number of children that can
; number then some children will be killed.
; Note: This value is mandatory.
pm = dynamic　　#以动态方式运行

; The number of child processes to be created when pm is set to 'static' and the
; maximum number of child processes to be created when pm is set to 'dynamic'.
; 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.
; Note: Used when pm is set to either 'static' or 'dynamic'
; Note: This value is mandatory.
pm.max_children = 50　　　　#最大子进程数

; 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 = 5　　　　#服务启动，先创建的服务数量

; 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　　#启动的最小空闲服务数量，应大于启动时创建的服务数

; 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 = 35　　#启动的最大空闲服务数量

; 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 = 500　　#每个子进程最多响应多少个请求，然后关闭

; The URI to view the FPM status page. If this value is not set, no URI will be
; recognized as a status page. By default, the status page shows the following
; information:
; accepted conn - the number of request accepted by the pool;
; pool - the name of the pool;
; may conflict with a real PHP file.
; Default Value: not set
pm.status_path = /pmstatus　　#启用此行,内置状态页,改成pmstatus

; may conflict with a real PHP file.
; Default Value: not set
ping.path = /ping　　　　#服务器远程健康状况探测，检测服务器是否正常

; This directive may be used to customize the response of a ping request. The
; response is formatted as text/plain with a 200 response code.
; Default Value: pong
ping.response = pong　　#探测回应

; The timeout for serving a single request after which the worker process will
; 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　　#响应超时时间，0表示不超时

; The timeout for serving a single request after which a PHP backtrace will be
; dumped to the 'slowlog' file. A value of '0s' means 'off'.
; Available units: s(econds)(default), m(inutes), h(ours), or d(ays)

; Set max core size rlimit.
; Possible Values: 'unlimited' or an integer greater or equal to 0
; Default Value: system defined value
;rlimit_core = 0

; 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

; 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

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 = 35

; 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.
