1. lamp简介

有了前面学习的知识的铺垫,今天可以来学习下第一个常用的web架构了。

所谓lamp,其实就是由Linux+Apache+Mysql/MariaDB+Php/Perl/Python的一组动态网站或者服务器的开源软件,除Linux外其它各部件本身都是各自独立的程序,但是因为经常被放在一起使用,拥有了越来越高的兼容度,共同组成了一个强大的Web应用程序平台。

LAMP指的是Linux(操作系统)、Apache(HTTP服务器)、MySQL(也指MariaDB,数据库软件)和PHP(有时也是指Perl或Python)的第一个字母,一般用来建立web应用平台。

2. web服务器工作流程

在说lamp架构平台的搭建前,我们先来了解下什么是CGI,什么是FastCGI,什么是......

web服务器的资源分为两种,静态资源和动态资源

  • 静态资源就是指静态内容,客户端从服务器获得的资源的表现形式与原文件相同。可以简单的理解为就是直接存储于文件系统中的资源
  • 动态资源则通常是程序文件,需要在服务器执行之后,将执行的结果返回给客户端

那么web服务器如何执行程序并将结果返回给客户端呢?下面通过一张图来说明一下web服务器如何处理客户端的请求

如上图所示

阶段①显示的是httpd服务器(即apache和php服务器通过FastCGI协议进行通信,且php作为独立的服务进程运行

阶段②显示的是php程序和mysql数据库间通过mysql协议进行通信。php与mysql本没有什么联系,但是由Php语言写成的程序可以与mysql进行数据交互。同理perl和python写的程序也可以与mysql数据库进行交互

2.1 cgi与fastcgi

上图阶段①中提到了FastCGI,下面我们来了解下CGI与FastCGI。

CGI(Common Gateway Interface,通用网关接口),CGI是外部应用程序(CGI程序)与WEB服务器之间的接口标准,是在CGI程序和Web服务器之间传递信息的过程。CGI规范允许Web服务器执行外部程序,并将它们的输出发送给Web浏览器,CGI将web的一组简单的静态超媒体文档变成一个完整的新的交互式媒体。

FastCGI(Fast Common Gateway Interface)是CGI的改良版,CGI是通过启用一个解释器进程来处理每个请求,耗时且耗资源,而FastCGI则是通过master-worker形式来处理每个请求,即启动一个master主进程,然后根据配置启动几个worker进程,当请求进来时,master会从worker进程中选择一个去处理请求,这样就避免了重复的生成和杀死进程带来的频繁cpu上下文切换而导致耗时

2.2 httpd与php结合的方式

httpd与php结合的方式有以下三种:

  • modules:php将以httpd的扩展模块形式存在,需要加载动态资源时,httpd可以直接通过php模块来加工资源并返回给客户端

httpd prefork:libphp5.so(多进程模型的php)
httpd event or worker:libphp5-zts.so(线程模型的php)
* CGI:httpd需要加载动态资源时,通过CGI与php解释器联系,获得php执行的结果,此时httpd负责与php连接的建立和断开等
* FastCGI:利用php-fpm机制,启动为服务进程,php自行运行为一个服务,https通过socket与php通信

较于CGI方式,FastCGI更为常用,很少有人使用CGI方式来加载动态资源

2.3 web工作流程

通过上面的图说明一下web的工作流程:

  • 客户端通过http协议请求web服务器资源
  • web服务器收到请求后判断客户端请求的资源是静态资源或是动态资源 > 若是静态资源则直接从本地文件系统取之返回给客户端。 > 否则若为动态资源则通过FastCGI协议与php服务器联系,通过CGI程序的master进程调度worker进程来执行程序以获得客户端请求的动态资源,并将执行的结果通过FastCGI协议返回给httpd服务器,httpd服务器收到php的执行结果后将其封装为http响应报文响应给客户端。在执行程序获取动态资源时若需要获得数据库中的资源时,由Php服务器通过mysql协议与MySQL/MariaDB服务器交互,取之而后返回给httpd,httpd将从php服务器收到的执行结果封装成http响应报文响应给客户端。

3. lamp平台构建

环境说明:

lamp平台软件安装次序:

    httpd --> mysql --> php

注意:php要求httpd使用prefork MPM

3.4 配置apache

3.4.1 启用代理模块

在apache httpd 2.4以后已经专门有一个模块针对FastCGI的实现,此模块为mod_proxy_fcgi.so,它其实是作为mod_proxy.so模块的扩展,因此,这两个模块都要加载,编辑httpd.conf文件,取消以下两行内容的注释:

  • LoadModule proxy_module modules/mod_proxy.so
  • LoadModule proxy_fcgi_module modules/mod_proxy_fcgi.so
//启用httpd的相关模块

[root@localhost ~]# sed -i '/proxy_fcgi_module/s/#//g' /etc/httpd24/httpd.conf

3.4.2 配置虚拟主机

在需要使用fcgi的虚拟主机中添加类似如下两行:

ProxyRequests Off       //关闭正向代理
ProxyPassMatch ^/(.*\.php)$ fcgi://127.0.0.1:9000/PATH/TO/DOCUMENT_ROOT/$1

例如:

ProxyPassMatch ^/(.*\.php)$ fcgi://127.0.0.1:9000/var/www/html/idfsoft.com/$1

以上设置表示把以.php结尾的文件请求发送到php-fpm进程,php-fpm至少需要知道运行的目录和URI,所以这里直接在fcgi://127.0.0.1:9000后指明了这两个参数,其它参数的传递已经被mod_proxy_fcgi.so进行了封装,不需要手动指定。

注意:

这里写的/var/www/html/是yum源安装方式生成的网页存放目录,这里必须改成你编译安装指定的网页存放路径,禁止直接复制我这里的路径
这里的idfsoft.com是域名,你必须改成你所使用的域名,禁止直接复制此处的域名
这里的$1表示匹配所有以.php结尾的http请求

3.5 验证

1.修改/etc/hosts文件,添加域名与IP的映射
2.在浏览器上使用域名访问,若看到以下界面则表示lamp架构搭建成功,否则请检查你的操作
