Name of pool. Used in logs and stats. default Address to accept fastcgi requests on. Valid syntax is ‘ip.ad.re.ss:port’ or just ‘port’ or ‘/path/to/unix/socket’ 127.0.0.1:9000 Set listen(2) backlog -1 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. 0666 Additional php.ini defines, specific to this pool of workers. /usr/sbin/sendmail -t -i 0 Unix user of processes www Unix group of processes website Process manager settings Sets style of controling worker process count. Valid values are ‘static’ and ‘apache-like’ static 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. 20 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 20 Sets the desired minimum number of idle server processes. Used only when ‘apache-like’ pm_style is selected 5 Sets the desired maximum number of idle server processes. Used only when ‘apache-like’ pm_style is selected 250 Time limit on waiting execution of single request Should be used when ‘max_execution_time’ ini option does not terminate execution for some reason 31s Set open file desc rlimit 51200 Set max core size rlimit 0 Chroot to this directory at the start Chdir to this directory at the start Redirect workers’ stdout and stderr into main error log. If not set, they will be redirected to /dev/null, according to FastCGI specs yes 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 51200 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. 127.0.0.1 Pass environment variables like LD_LIBRARY_PATH All $VARIABLEs are taken from current environment $HOSTNAME /usr/local/bin:/usr/bin:/bin /tmp /tmp /tmp $OSTYPE $MACHTYPE 2

和原始配置文件的差别 用户组->www max_children=64 MaxApareServers=250 rlimit_files=51200 max_requests=51200 去掉注释 7.优化文件句柄并开启php ulimit -SHn 51200 /opt/php/sbin/php-fpm start #/opt/php/sbin/php-fpm还有其他参数，包括：start|stop|quit|restart|reload|logrotate，修改php.ini后不重启php-cgi，重新加载配置文件使用reload。
