openresty
一．前言
我们都知道Nginx有很多的特性和好处，但是在Nginx上开发成了一个难题，Nginx模块需要用C开发，而且必须符合一系列复杂的规则，最重要的用C开发模块必须要熟悉Nginx的源代码，使得开发者对其望而生畏。为了开发人员方便，所以接下来我们要介绍一种整合了Nginx和lua的框架，那就是OpenResty，它帮我们实现了可以用lua的规范开发，实现各种业务，并且帮我们弄清楚各个模块的编译顺序。关于OpenResty，我想大家应该不再陌生，随着系统架构的不断升级、优化，OpenResty在被广泛的应用。
二．OpenResty运行原理
Nginx 采用的是 master-worker 模型，一个 master 进程管理多个 worker 进程，基本的事件处理都是放在 woker 中，master 负责一些全局初始化，以及对 worker 的管理。在OpenResty中，每个 woker 使用一个 LuaVM，当请求被分配到 woker 时，将在这个 LuaVM 里创建一个 coroutine(协程)。协程之间数据隔离，每个协程具有独立的全局变量_G。
ps. 协程和多线程下的线程类似：有自己的堆栈，自己的局部变量，有自己的指令指针，但是和其他协程程序共享全局变量等信息。线程和协程的主要不同在于：多处理器的情况下，概念上来说多线程是同时运行多个线程，而协程是通过代码来完成协程的切换，任何时刻只有一个协程程序在运行。并且这个在运行的协程只有明确被要求挂起时才会被挂起。
原理图如下：
三．OpenResty的优势
首先我们选择使用OpenResty，其是由Nginx核心加很多第三方模块组成，其最大的亮点是默认集成了Lua开发环境，使得Nginx可以作为一个Web Server使用。
借助于Nginx的事件驱动模型和非阻塞IO，可以实现高性能的Web应用程序。
而且OpenResty提供了大量组件如Mysql、Redis、Memcached等等，使在Nginx上开发Web应用更方便更简单。目前在京东如实时价格、秒杀、动态服务、单品页、列表页等都在使用Nginx+Lua架构，其他公司如淘宝、去哪儿网等。
四．Nginx和lua的简介
- Nginx：
(1) Nginx的优点
轻量级同样起web 服务比apache占用更少内存及资源
抗并发nginx 处理请求异步非阻塞而apache 则阻塞型高并发下nginx 能保持低资源低消耗高性能
高度模块化设计编写模块相对简单
社区活跃各种高性能模块出品迅速啊
(2) Nginx为什么性能高，占用内存少
众所周知，nginx性能高，而nginx的高性能与其架构是分不开的。在这里，我们简单粗略的介绍一下nginx的架构。
首先，nginx采用的是多多进程模式，好处是什么呢？首先，对于每个worker进程来说，独立的进程，不需要加锁，所以省掉了锁带来的开销，同时在编程以及问题查找时，也会方便很多。其次，采用独立的进程，可以让互相之间不会影响，一个进程退出后，其它进程还在工作，服务不会中断，master进程则很快启动新的worker进程。当然，worker进程的异常退出，肯定是程序有bug了，异常退出，会导致当前worker上的所有请求失败，不过不会影响到所有请求，所以降低风险。
Nginx是采用异步非阻塞的方式去处理请求的，什么是异步非阻塞呢？其实就是当一个线程调用出现等待的io之类的情况时，而不是阻塞在这里，而是去处理别的事情，等io准备好了，然后再去执行，具体的我就不在这里和大家描述了。
- lua:
(1) Lua 是一个小巧的脚本语言。作者是巴西人。该语言的设计目的是为了嵌入应用程序中，从而为应用程序提供灵活的扩展和定制功能
(2) Lua的特点：
Lua脚本可以很容易的被C/C++代码调用，也可以反过来调用C/C++的函数，这使得Lua在应用程序中可以被广泛应用。不仅仅作为扩展脚本，也可以作为普通的配置文件，代替XML,Ini等文件格式，并且更容易理解和维护。
Lua由标准C编写而成，代码简洁优美，几乎在所有操作系统和平台上都可以编译，运行。一个完整的Lua解释器不过200k，在目前所有脚本引擎中，Lua的速度是最快的。这一切都决定了Lua是作为嵌入式脚本的最佳选择。
