高并發壓力測試：

[root@test5 ~]# ab -c 10 -n 1000 http://172.25.1.5/index.php

[root@test5 ~]# ab -c 10 -n 1000 http://172.25.1.5/example.php

說明：

???????? example.php的頁面緩存中不存在，所以直接訪問了服務器，以至時間比較長；而index.php在memcache中有緩存，頁面是緩存，以至時間比較短。

nginx加緩存

OpenResty:

???????????????? 是一個基于 Nginx 與 Lua 的高性能 Web 平臺，其內部集成了大量精良的 Lua 庫、第三方模塊以及大多數的依賴項。用于方便地搭建能夠處理超高并發、擴展性極高的動態 Web 應用、Web 服務和動態網關。OpenResty的目標是讓你的Web服務直接跑在 Nginx 服務內部，充分利用 Nginx 的非阻塞 I/O 模型，不僅僅對 HTTP 客戶端請求,甚至于對遠程后端諸如 MySQL

PostgreSQL、Memcached 以及 Redis 等都進行一致的高性能響應。

Tomcat簡介： ?

?????? Tomcat 服務器是一個免費的開放源代碼的Web 應用服務器，屬于輕量級應用服務器，在中小型系統和并發訪問用戶不是很多的場合下被普遍使用，是開發和調試JSP 程序的首選。可以這樣認為，當在一臺機器上配置好Apache 服務器，可利用它響應HTML頁面的訪問請求。實際上Tomcat是Apache 服務器的擴展，但運行時它是獨立運行的，所以當你運行tomcat 時，它實際上作為一個與Apache 獨立的進程單獨運行的。當配置正確時，Apache 為HTML頁面服務，而Tomcat 實際上運行JSP 頁面和Servlet。另外，Tomcat 服務器具有處理HTML頁面的功能，它還是一個Servlet和JSP容器，獨立的Servlet容器是Tomcat的默認模式。不過，Tomcat處理靜態HTML的能力不如Apache服務器。目前Tomcat最新版本為9.0。

jdk簡介：

?????????? 是 Java 語言的軟件開發工具包，主要用于移動設備、嵌入式設備上的java應用程序。JDK是整個java開發的核心，它包含了JAVA的運行環境（JVM+Java系統類庫）和JAVA工具。

工作原理：

?????? server端向nginx請求java動態頁面的時候,由于nginx只能處理靜態頁面，所以向后面傳送給jdk來處理java請求，處理之后通過nginx返回請求并交給server端。
