[www]

;listen string设置接受 FastCGI 请求的地址。可用格式为：'ip:port'，'port'，'/path/to/unix/socket'。每个进程池都需要设置。

listen = /dev/shm/php-cgi.sock

;listen.backlog int设置 listen(2) 的半连接队列长度。“-1”表示无限制。默认值：-1。

listen.backlog = -1

;listen.allowed_clients string设置允许连接到 FastCGI 的服务器 IPV4 地址。等同于 PHP FastCGI (5.2.2+) 中的 FCGI_WEB_SERVER_ADDRS 环境变量。仅对 TCP 监听起作用。每个地址是用逗号分隔，如果没有设置或者为空，则允许任何服务器请求连接。默认值：any。

listen.allowed_clients = 127.0.0.1

;listen.owner string如果使用，表示设置 Unix 套接字的权限。在Linux中，读写权限必须设置，以便用于 WEB 服务器连接。在很多 BSD 派生的系统中可以忽略权限允许自由连接。默认值：运行所使用的用户和组，权限为 0666。

;listen.owner = www

;listen.group = www

;listen.mode = 0666

;user = www

;group = www

listen.owner = www

listen.group = www

listen.mode = 0660

user = www

group = www

;pm string

;设置进程管理器如何管理子进程。可用值：static，ondemand，dynamic。必须设置。

;static - 子进程的数量是固定的(pm.max_children)。

;ondemand - 进程在有需求时才产生(当请求时，与 dynamic 相反，pm.start_servers 在服务启动时即启动。

;dynamic - 子进程的数量在下面配置的基础上动态设置：pm.max_children，pm.start_servers，pm.min_spare_servers，pm.max_spare_servers。

pm = dynamic

;pm.max_children int pm 设置为 static 时表示创建的子进程的数量，pm 设置为 dynamic 时表示最大可创建的子进程的数量。必须设置。

;该选项设置可以同时提供服务的请求数限制。类似 Apache 的 mpm_prefork 中 MaxClients 的设置和 普通PHP FastCGI中的 PHP_FCGI_CHILDREN 环境变量。

pm.max_children = 50

;pm.start_servers int 设置启动时创建的子进程数目。仅在 pm 设置为 dynamic 时使用。默认值：min_spare_servers + (max_spare_servers - min_spare_servers) / 2。

pm.start_servers = 20

pm.min_spare_servers = 10

pm.max_spare_servers = 30

pm.max_requests = 500

pm.process_idle_timeout = 10s

request_terminate_timeout = 30

request_slowlog_timeout = 0

pm.status_path = /php-fpm_status

slowlog = log/slow.log
