Linux下搭建LAMP是經典的不能再經典的中小企業站點建構平台。它的全名是Linux+Apache+Mysql+PHP，常用來搭建動態網站，本身都是各自獨立的程序，但是因為常被放在一起使用，擁有了越來越高的兼容度，共同組成了一個強大的Web應用程式平台。因此在網路上也有比叫有名的LAMP一鍵安裝解決方案。但是對於維運人員來講，有必要了解其完成的安裝過程。本文主要描述基於CentOS 6 下使用yum方式來快速建構LAMP平台(Linux安裝忽略)。
一、準備yum源(本文使用了163鏡像)
<code><span># mv /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.backup</span><span># wget http://mirrors.163.com/.help/CentOS6-Base-163.repo -P /etc/yum.repos.d/</span><span># yum clean all</span><span># yum makecache</span></code>
二、安裝apache httpd
詳細可以參考：Linux下安裝Apache httpd
<code><span>###检查是否已安装httpd</span><span># rpm -qa|grep httpd</span><span> httpd-tools-2.2.15-45.el6.centos.x86_64</span><span> httpd-2.2.15-45.el6.centos.x86_64</span><span># yum -y install httpd ###此时我们看到httpd的小版本从45变成了53</span><span># rpm -qa|grep httpd</span><span> httpd-tools-2.2.15-53.el6.centos.x86_64</span><span> httpd-2.2.15-53.el6.centos.x86_64</span><span>###查询生成的相关配置文件</span><span># rpm -qc httpd|grep conf</span><span> /etc/httpd/conf.d/welcome.conf</span><span> /etc/httpd/conf/httpd.conf</span><span> /etc/httpd/conf/magic</span><span> /etc/sysconfig/htcacheclean</span><span> /etc/sysconfig/httpd</span><span>###启动httpd</span><span># /etc/init.d/httpd start</span><span> Starting httpd: [ OK ]</span><span># netstat -nltp|grep 80</span><span> tcp 0 0 :::80 :::* LISTEN 7621/httpd</span><span>###验证web服务</span><span># curl -I http://localhost</span><span> HTTP/1.1 403 Forbidden</span><span> Date: Tue, 12 Jul 2016 09:25:15 GMT</span><span> Server: Apache/2.2.15 (CentOS)</span><span> Accept-Ranges: bytes</span><span> Content-Length: 4961</span><span> Connection: close</span><span> Content-Type: text/html; charset=UTF-8</span><span>###编写一个php页面测试</span><span># echo "</span><span>> <html></span><span>> <h1>This is a php test page.</h1></span><span>> <?php</span><span>> phpinfo();</span><span>> ?></span><span>> </html>">>/var/www/html/index.php </span><span>###测试结果为phpinfo函数没有被解释</span><span># curl http://localhost/index.php</span><span> <html></span><span> <h1>This is a php test page.</h1></span><span> <?php</span><span> phpinfo();</span><span> ?></span><span> </html></span></code>

1、apache httpd與php之間的銜接是透過模組化的方式來實現。
