要让PHP以FastCGI的方式与nginx进行交互，需要有PHP-FPM模块的支持。
安装PHP-FPM
1
[root@localhost ~]# yum -y install php-fpm

[root@localhost ~]# php-fpm -v
PHP 5.4.16 (fpm-fcgi) (built: Apr 12 2018 19:03:25)
Copyright (c) 1997-2013 The PHP Group
Zend Engine v2.4.0, Copyright (c) 1998-2013 Zend Technologies
启动PHP-FPM
1
[root@localhost ~]# systemctl start php-fpm
以上安装完成后，接下来，配置Nginx支持PHP（FastCGI方式）。
修改 /usr/local/nginx/conf/nginx.conf 把如下图红色框中的#去掉就可以了。
这里面都是默认的，root是配置php程序放置的根目录。
还需要修改的就是fastcgi_param中的/scripts为$document_root
修改完成后，让nginx重新加载配置以生效：
1
[root@localhost ~]# /usr/local/nginx/sbin/nginx -s reload

[root@localhost ~]# cd /usr/local/nginx/html/

[root@localhost html]# vim index.php
[root@localhost html]# cat index.php
<?php
phpinfo();
?>
