錯誤提示建議增加pm.start_servers數量，開啟我的php-fpm配置：

pm.max_children = 50


; thenumberofchild processescreatedonstartup.


; note: usedonlywhenpmis setto 'dynamic'


; default value: min_spare_servers + (max_spare_servers - min_spare_servers) / 2


pm.start_servers = 15


; thedesiredminimumnumberofidleserverprocesses.


; note: usedonlywhenpmis setto 'dynamic'


; note: mandatorywhenpmis setto 'dynamic'


pm.min_spare_servers = 5


; thedesiredmaximumnumberofidleserverprocesses.


; note: usedonlywhenpmis setto 'dynamic'


; note: mandatorywhenpmis setto 'dynamic'


pm.max_spare_servers = 35
這裡pm.start_servers之前我設定為5，注意配置檔案也說明start_servers的值預設是max_spare_servers-min_spare_servers的一半。(ps:具體的值要根據伺服器配置情況和壓力測試得出)

**伺服器是阿里雲1g頻寬，1g記憶體，1核cpu配置，關鍵還在一台機子上裝了資料庫，redis各種服務。

pm.max_children = 24
static模式下建立的子程序數或dynamic模式下同一時刻允許最大的php-fpm子程序數量

pm.start_servers = 16
動態方式下的起始php-fpm程序數量

pm.min_spare_servers = 12
動態方式下伺服器空閒時最小php-fpm程序數量

pm.max_spare_servers = 24
動態方式下伺服器空閒時最大php-fpm程序數量

經驗人士的總結：

一般php-fpm程序占用20~30m左右的記憶體就按30m算。如果單獨跑php-fpm，動態方式起始值可設定物理記憶體mem/30m，由於大家一般nginx、mysql都在一台機器上，於是預留一半給它們，即php-fpm程序數為$mem/2/30。

調整之後的幾個值是：

pm = dynamic


pm.max_children = 50


pm.start_servers = 15


pm.min_spare_servers = 10


pm.max_spare_servers = 40
重啟php-fpm服務：service php70-php-fpm reload，繼續使用top命令檢視記憶體使用情況，發現十幾個php-fpm啟動。

php fpm新增service服務

nginx通過fastcgi執行php比apache包含php環境有明顯的優勢,最近有訊息稱,php5.4將很有可能把php fpm補丁包含在核心裡,nginx伺服器平台上執行php將更加輕鬆,下面我們就來看一篇php fpm平滑啟動並配置服務例子。我的php是原始碼安裝的。php fpm在php ...

php fpm服務啟動指令碼

在 php fpm還是打補丁的時候，php fpm重啟只需要執行php fpm restart或者reload,自從php5.3之後，php fpm的啟動和停止顯得比較麻煩，特意改寫了乙份 nginx 的自啟動指令碼，如下指令碼phpfpm usr local php 5.3.10 sbin php...
