;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
