1.安装PHP，如下两条安装命令：

yum install epel-release -y

rpm -Uvh https://mirror.webtatic.com/yum/el7/webtatic-release.rpm

安装PHP扩展包：

普通安装：

yum -y install php72w php72w-cli php72w-fpm php72w-common php72w-devel

较全面安装：

yum -y install php72w php72w-cli php72w-fpm php72w-common php72w-devel php72w-embedded php72w-gd php72w-mbstring php72w-mysqlnd php72w-opcache php72w-pdo php72w-xm

查看版本：php -v

2.在nginx配置集成php

编辑nginx.conf添加如下配置server块：

server
    {
     listen 192.168.241.15:80;
     server_name 192.168.241.15;
     access_log /home/logs/serverphp.access.log combined;

     location /
     {
      index index.php index.html index.htm;

     }
     
     location ~ \.php$
     {
         root /home/server15;
         fastcgi_pass   127.0.0.1:9000;
         fastcgi_index  index.php;
         fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_script_name;
         include        fastcgi_params;
     }

    }

3.重启nginx和启动php-fpm fastcgi:

/usr/nginx/sbin/nginx

php-fpm -D

在/home/server15目录新建index.php文件就可以测试了：

http://192.168.241.15/index.php
