http是Apache超文本传输协议服务器的主程序。它是一个独立的后台进程，能够处理请求的子进程和线程。
http常用用的两个版本是httpd-2.2和httpd-2.4
| 名称 | 特点 |
|---|---|
| 高度模块化 | core + modules，核心加模块，想要什么功能添加什么模块； |
| DSO | Dynamic Shared Object，动态共享库； |
| MPM | Multipath processing Modules 多路处理模块。 |
# 工作模型
一个主进程：
负责生成子进程及回收子进程
负责创建套接字、接受请求，并将其派发给某子进程进行处理
n个子进程：
每个子进程处理一个请求
# 注意：
会预先生成几个空闲进程，随时等待用于响应用户请求，最大不会超过1024个
# 工作模型
一个主进程：
负责生成子进程、创建套接字、接受请求，并将其派发给某子进程进行处理
多个子进程：
每个子进程负责生成多个线程
每个线程：
负责响应用户请求
# 工作模型：
一个主进程：
负责生成子进程、创建套接字、接受请求，并将其派发给某子进程进行处理
子进程：
基于事件驱动机制直接响应多个请求

| 法则 | 功能 |
|---|---|
| Require all granted | 允许所有主机访问 |
| Require all deny | 拒绝所有主机访问 |
| Require ip IPADDR | 授权指定来源地址的主机访问 |
| Require not ip IPADDR | 拒绝指定来源地址的主机访问 |
| Require host HOSTNAME | 授权指定来源主机名的主机访问 |
| Require not host HOSTNAME | 拒绝指定来源主机名的主机访问 |
| IPADDR的类型 | HOSTNAME的类型 |
|---|---|
| IP：192.168.1.1 Network/mask：192.168.1.0/255.255.255.0 Network/Length：192.168.1.0/24 Net：192.168 | FQDN：特定主机的全名 DOMAIN：指定域内的所有主机 |
注意：httpd-2.4版本在配置文件加入Requirt才是默认是拒绝所有主机访问的，所以安装以后必须做显示授权访问
配置示例： 允许除了IP192.168.111.1以外的所有主机访问

#
# ServerName gives the name and port that the server uses to identify itself.

主机名解析
Linux 和MAC系统中修改 /etc/host
windows主机名解析 在C:\windows\system32\drivers\etc\hosts找到文件无法修改，需要把文件拖到桌面修改，添加解析，再放回原位
https（全称：Hyper Text Transfer Protocol over SecureSocket Layer），是以安全为目标的 http 通道，在 http 的基础上通过传输加密和身份认证保证了传输过程的安全性。
mod_ssl 模块可以实现https加密认证。

我正在尝试使用ruby和Savon来使用网络服务。测试服务为http://www.webservicex.net/WS/WSDetails.aspx?WSID=9&CATID=2require'rubygems'require'savon'client=Savon::Client.new"http://www.webservicex.net/stockquote.asmx?WSDL"client.get_quotedo|soap|soap.body={:symbol=>"AAPL"}end返回SOAP异常。检查soap信封，在我看来soap请求没有正确的命名空间。任何人都可以建议我
我想安装一个带有一些身份验证的私有(private)Rubygem服务器。我希望能够使用公共(public)Ubuntu服务器托管内部gem。我读到了http://docs.rubygems.org/read/chapter/18.但是那个没有身份验证-如我所见。然后我读到了https://github.com/cwninja/geminabox.但是当我使用基本身份验证(他们在他们的Wiki中有)时，它会提示从我的服务器获取源。所以。如何制作带有身份验证的私有(private)Rubygem服务器？这是不可能的吗？谢谢。编辑:Geminabox问题。我尝试“捆绑”以安装新的gem..
最近，当我启动我的Rails服务器时，我收到了一长串警告。虽然它不影响我的应用程序，但我想知道如何解决这些警告。我的估计是imagemagick以某种方式被调用了两次？当我在警告前后检查我的git日志时。我想知道如何解决这个问题。-bcrypt-ruby(3.1.2)-better_errors(1.0.1)+bcrypt(3.1.7)+bcrypt-ruby(3.1.5)-bcrypt(>=3.1.3)+better_errors(1.1.0)bcrypt和imagemagick有关系吗？/Users/rbchris/.rbenv/versions/2.0.0-p247/lib/ru
在Rails4.0.2中，我使用s3_direct_upload和aws-sdkgems直接为s3存储桶上传文件。在开发环境中它工作正常，但在生产环境中它会抛出如下错误，ActionView::Template::Error(noimplicitconversionofnilintoString)在View中，create_cv_url,:id=>"s3_uploader",:key=>"cv_uploads/{unique_id}/${filename}",:key_starts_with=>"cv_uploads/",:callback_param=>"cv[direct_uplo
我想在Ruby中创建一个用于开发目的的极其简单的Web服务器(不，不想使用现成的解决方案)。代码如下:#!/usr/bin/rubyrequire'socket'server=TCPServer.new('127.0.0.1',8080)whileconnection=server.acceptheaders=[]length=0whileline=connection.getsheaders想法是从命令行运行这个脚本，提供另一个脚本，它将在其标准输入上获取请求，并在其标准输出上返回完整的响应。到目前为止一切顺利，但事实证明这真的很脆弱，因为它在第二个请求上中断并出现错误:/usr/b
您如何在Rails中的实时服务器上进行有效调试，无论是在测试版/生产服务器上？我试过直接在服务器上修改文件，然后重启应用，但是修改好像没有生效，或者需要很长时间(缓存？)我也试过在本地做“脚本/服务器生产”，但是那很慢另一种选择是编码和部署，但效率很低。有人对他们如何有效地做到这一点有任何见解吗？ 最佳答案 我会回答你的问题，即使我不同意这种热修补服务器代码的方式:)首先，你真的确定你已经重启了服务器吗？您可以通过跟踪日志文件来检查它。您更改的代码显示的View可能会被缓存。缓存页面位于tmp/cache文件夹下。您可以尝试手动删除

我有一个使用PDFKit呈现网页的pdf版本的Rails应用程序。我使用Thin作为开发服务器。问题是当我处于开发模式时。当我使用“bundleexecrailss”启动我的服务器并尝试呈现任何PDF时，整个过程会陷入僵局，因为当您呈现PDF时，会向服务器请求一些额外的资源，如图像和css，看起来只有一个线程.如何配置Rails开发服务器以运行多个工作线程？非常感谢。 最佳答案 我找到的最简单的解决方案是unicorn.geminstallunicorn创建一个unicorn.conf:worker_processes3然后使用它:
