本文打造易于复制粘贴的lnmp安装方法。
相比较其他编译安装的教程，本文解除了软件版本锁定，理论上，永远安装的是最新稳定版且支持软件升级。
编译教程在写作时往往使用当时的最新稳定版软件，但是稍过时日，新的漏洞出来，很快会将读者带入危险，因为软件已经过时了。严重不建议新手使用编译方法安装lnmp。
环境CentOS 6.5 x64

fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
include fastcgi_params;

sed -i 's/index.html/& index.php/' /etc/nginx/nginx.conf
echo "<?php phpinfo();phpinfo(INFO_MODULES);?>" >/var/www/html/index.php

mysql配置
有条件的话，给mysql单独分个区作为datadir
[mysqld]
datadir=/data
其他参数可以参考/usr/share/mysql下的示例文件
mysql基本加固，（设置密码，限制访问等）

iptables防火墙，需要根据自己设置，下面仅仅是个示例

通过浏览器访问系统IP应该就已经能够看到php信息了。
