有了前面学习的知识的铺垫,今天能够来学习下第一个经常使用的web架构了。html
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外其它各部件自己都是各自独立的程序,可是由于常常被放在一块儿使用,拥有了愈来愈高的兼容度,共同组成了一个强大的Web应用程序平台。python
LAMP指的是Linux(操做系统)、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,通常用来创建web应用平台。mysql
在说lamp架构平台的搭建前,咱们先来了解下什么是CGI,什么是FastCGI,什么是......linux
web服务器的资源分为两种,静态资源和动态资源web
静态资源就是指静态内容,客户端从服务器得到的资源的表现形式与原文件相同。能够简单的理解为就是直接存储于文件系统中的资源
动态资源则一般是程序文件,须要在服务器执行以后,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?下面经过一张图来讲明一下web服务器如何处理客户端的请求
如上图所示sql
阶段①显示的是httpd服务器(即apache)和php服务器经过FastCGI协议进行通讯,且php做为独立的服务进程运行数据库
阶段②显示的是php程序和mysql数据库间经过mysql协议进行通讯。php与mysql本没有什么联系,可是由Php语言写成的程序能够与mysql进行数据交互。同理perl和python写的程序也能够与mysql数据库进行交互apache
上图阶段①中提到了FastCGI,下面咱们来了解下CGI与FastCGI。json
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规范容许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是经过启用一个解释器进程来处理每一个请求,耗时且耗资源,而FastCGI则是经过master-worker形式来处理每一个请求,即启动一个master主进程,而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上下文切换而致使耗时
httpd与php结合的方式有如下三种:
CGI:httpd须要加载动态资源时,经过CGI与php解释器联系,得到php执行的结果,此时httpd负责与php链接的创建和断开等
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经过socket与php通讯
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经过socket与php通讯
经过上面的图说明一下web的工做流程:

lamp平台软件安装次序:

注意:php要求httpd使用prefork MPM

在apache httpd 2.4之后已经专门有一个模块针对FastCGI的实现,此模块为mod_proxy_fcgi.so,它实际上是做为mod_proxy.so模块的扩展,所以,这两个模块都要加载,编辑httpd.conf文件,取消如下两行内容的注释:
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_module/s/#//g' /etc/httpd24/httpd.conf [root@localhost ~]# sed -i '/proxy_fcgi_module/s/#//g' /etc/httpd24/httpd.conf
在须要使用fcgi的虚拟主机中添加相似以下两行:
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至少须要知道运行的目录和URI,因此这里直接在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,不须要手动指定。
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,这里必须改为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,你必须改为你所使用的域名,禁止直接复制此处的域名
这里的$1表示匹配全部以.php结尾的http请求
