LNMP架構介紹
- 和LAMP不同的是，提供web服務的是Nginx
- 並且php是作為一個獨立服務存在的，這個服務叫做php-fpm
- Nginx直接處理靜態請求，動態請求會轉發給php-fpm
MySQL重新安裝
- MySQL是通過免編譯二進位制安裝包進行安裝的，需要刪除對應的目錄後進行重灌，重灌之前要先停止服務
[[email protected] ~]# ps -ef | grep mysql

Nginx 介紹
- Nginx官網 nginx.org
- Nginx應用場景：web服務、反向代理、負載均衡
- Nginx著名分支，淘寶基於Nginx開發的Tengine，使用上和Nginx一致，服務名，配置檔名都一樣，和Nginx的最大區別在於Tenging增加了一些定製化模組，在安全限速方面表現突出，另外它支援對js，css合併
- Nginx核心+lua相關的元件和模組組成了一個支援lua的高效能web容器openresty，參考 http://jinnianshilongnian.iteye.com/blog/2280928
