什么是Apache进程模型？
我一直在谷歌上搜索了一段时间这个问题，但没有得到回应。什么是Apache进程模型？
I have been googling this question for some time but got no answers. What's the Apache process model?
通过流程模型，我的意思是Apache如何管理进程或线程处理HTTP请求。
By process model, I mean how Apache manage process or thread to handling HTTP request.
这是否为叉每个HTTP请求一个进程？
Does it fork one process for each HTTP request?
是否有进程/线程池？
我们可以配置它？
有没有在线文档这样的Apache细节？
Is there any online doc for such Apache details?
这取决于你的系统和配置上：看的核心功能和多处理模块：你可以使用，例如：
This depends on your system and configuration : see Core Features and Multi-Processing Modules : you could use, for instance :
- 的Apache MPM WINNT在Windows - 一个使用线程
- 或 Apache的MPM prefork - 一个使用过程
- 甚至 Apache的MPM工人 - 这同时使用多个进程和线程。
- Apache MPM winnt on windows -- that one uses threads
- Or Apache MPM prefork -- that one uses processes
- Or even Apache MPM worker -- which uses both several processes and threads.
结果
引用最后一个页面，Apache的MPM工人：
Quoting the page of the last one, Apache MPM worker :
这多处理模块（MPM）
实现了混合多处理
多线程服务器。结果使用
线程服务请求时，它能够
服务于大量的请求
用较少的系统资源比
基于进程的服务器。结果，然而，它
保留了大部分的稳定性
通过保持基于流程的服务器
提供多个进程，每个
有许多线程。
This Multi-Processing Module (MPM) implements a hybrid multi-process multi-threaded server.
By using threads to serve requests, it is able to serve a large number of requests with fewer system resources than a process-based server.
However, it retains much of the stability of a process-based server by keeping multiple processes available, each with many threads.
