php-fpm的pool,慢執行日誌,定義open_basedir,程序管理

php-fpm的pool
主要用來隔離各個站點，相互不影響。當某個網站出問題時，不影響到其他的站點。
增加池子配置，例如增加 test.com

程序管理
- pm = dynamic ;動態程序管理，也可以是static
- pm.max_children = 50 ;最大子程序數，ps aux可以檢視
- pm.start_servers = 20 ;啟動服務時會啟動的程序數
- pm.min_spare_servers = 5 ;定義在空閒時段，子程序數的最少數量，如果達到這個數值時，php-fpm服務會自動派生新的子程序。
- pm.max_spare_servers = 35 ;定義在空閒時段，子程序數的最大值，如果高於這個數值就開始清理空閒的子程序。
- pm.max_requests = 500 ;定義一個子程序最多處理的請求數，也就是說在一個php-fpm的子程序最多可以處理這麼多請求，當達到這個數值時，它會自動退出。
