這篇文章主要介紹Linux平臺PHP5.4如何設置FPM線程數量,文中介紹的非常詳細,具有一定的參考價值,感興趣的小伙伴們一定要看完!
具體如下:
PHP5.4安裝完畢后,FPM的默認配置文件位于/usr/local/php/etc/php-fpm.conf.default
>cp /usr/local/php/etc/php-fpm.conf.default /usr/local/php/etc/php-fpm.conf >vim /usr/local/php/etc/php-fpm.conf
輸入”/www”,搜索www所在的POOL
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) / 2 pm.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
解釋一下:
pm = dynamic 如何控制子進程,選項有static和dynamic,默認采用dynamic;如果選擇static,則由pm.max_children指定固定的子進程數。
如果選擇dynamic,則由以下參數決定:
pm.max_children | 子進程最大數 |
pm.start_servers | 啟動時的進程數 |
pm.min_spare_servers | 保證空閑進程數最小值,如果空閑進程小于此值,則創建新的子進程 |
pm.max_spare_servers | 保證空閑進程數最大值,如果空閑進程大于此值,則進行清理。對于專用服務器,pm可以設置為static。 |
pm.max_requests | 設置每個子進程重生之前服務的請求數. 對于可能存在內存泄漏的第三方模塊來說是非常有用的. 如果設置為 '0′ 則一直接受請求. 設置為500就可以了(默認0)。 |
將值修改為如下:
pm.max_children = 32 pm.start_servers = 16 pm.min_spare_servers = 8 pm.max_spare_servers = 32 pm.max_requests = 500
:wq 保存退出VIM
>/usr/local/php/sbin/php-fpm -t NOTICE: configuration file /usr/local/php/etc/php-fpm.conf test is successful
測試配置文件是否正常,沒問題,殺掉當前的FPM進程
>/usr/local/php/sbin/php-fpm
啟動
