问求大侠帮忙 nginx访问index.php 结果直接下载网页了？

求大侠帮忙 ,我是小白

centos7 +nginx1.12+php7.1

问题:nginx 访问 index.php 结果 直接下载网页了

描述:

在浏览器中，访问 CentOS 云主机公网 IP，查看 Nginx 服务可以正常运行

配置nginx文件内容如下vim /etc/nginx/conf.d/default.conf

=========================================================================

server {

listen 80;

root /usr/share/nginx/html;

server_name localhost;

#charset koi8-r;

#access_log /var/log/nginx/log/host.access.log main;

location / {

index index.php index.html index.htm;

}

#error_page 404 /404.html;

#redirect server error pages to the static page /50x.html

#

error_page 500 502 503 504 /50x.html;

location = /50x.html {

root /usr/share/nginx/html;

}

#pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000

#

location ~ .php$ {

fastcgi_pass 127.0.0.1:9000;

fastcgi_index index.php;

fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;

include fastcgi_params;

}

}

=====================================================================

然后新建了index.php文件

vim /usr/share/nginx/html/index.php

但访问浏览器时 却直接下载了 index.php文件 http://云主机的公网 IP/index.php

恳请哪位大侠 有空帮忙解答下 非常感谢
