1. lamp简介
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
2.3 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
w- eb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：
| 系统平台 | IP | 需要安装的服务 |
|---|---|---|
| centos7 redhat7 |
192.168.163.128 | httpd-2.4 mysql-5.7 php php-mysql |
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@cl ~]# sed -i '/proxy_module/s/#//g' /etc/httpd24/httpd.conf
[root@cl ~]# 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/$1
//创建虚拟主机目录并生成php测试页面
[root@cl ~]# mkdir /usr/local/apache/htdocs/cljhfy.com
[root@cl ~]# cat > /usr/local/apache/htdocs/cljhfy.com/index.php <<EOF
<?php
phpinfo();
?>
EOF
[root@cl ~]# chown -R apache.apache /usr/local/apache/htdocs/
[root@cl ~]# ll /usr/local/apache/htdocs/ -d
drwxr-xr-x 3 apache apache 44 Aug 16 14:50 /usr/local/apache/htdocs/
//在配置文件的最后加入以下内容
[root@cl ~]# vim /etc/httpd24/httpd.conf
<VirtualHost *:80>
DocumentRoot "/usr/local/apache/htdocs/cljhfy.com"
ServerName www.cljhfy.com
ProxyRequests Off
ProxyPassMatch ^/(.*.php)$ fcgi://127.0.0.1:9000/usr/local/apache/htdocs/cljhfy.com/$1
<Directory "/usr/local/apache/htdocs/cljhfy.com">
Options none
AllowOverride none
Require all granted
</Directory>
</VirtualHost>
//搜索AddType，添加以下内容
# If the AddEncoding directives above are commented-out, then you
# probably should define those extensions to indicate media types:
#
AddType application/x-compress .Z
AddType application/x-gzip .gz .tgz
AddType application/x-httpd-php .php //添加此行
AddType application/x-httpd-php-source .phps //添加此行
[root@localhost ~]# sed -i '/ DirectoryIndex/s/index.html/index.php index.html/g' /etc/httpd24/httpd.conf
//重启apache服务
[root@cl ~]# apachectl stop
[root@cl ~]# ss -antl
