Linux平台PHP5.4设置FPM线程数量的方法

>cp /usr/local/php/etc/php-fpm.conf.default /usr/local/php/etc/php-fpm.conf>vim /usr/local/php/etc/php-fpm.conf

pm = dynamic; The number of child processes to be created when pm is set to 'static' and the; maximum number of child processes when pm is set to 'dynamic' or 'ondemand'.; 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. The below defaults are based on a server without much resources. Don't; forget to tweak pm.* to fit your needs.; Note: Used when pm is set to 'static', 'dynamic' or 'ondemand'; Note: This value is mandatory.pm.max_children = 5; 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) / 2pm.start_servers = 2; 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 = 1; 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 = 3; The number of seconds after which an idle process will be killed.; Note: Used only when pm is set to 'ondemand'; Default Value: 10s;pm.process_idle_timeout = 10s;; 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

pm.max_children = 32pm.start_servers = 16pm.min_spare_servers = 8pm.max_spare_servers = 32pm.max_requests = 500
