Answer 1

看下log吧，曾经犯过一个错误也是导致PHP不被解析，直接返回PHP文件并下载。当时的原因是我注释了PHP转发，然后浏览器请求形成了缓存，当我修改正确配置重启服务器后，由于缓存原因根本不去请求服务器。所以你这里建议你先重启nginx，清除下浏览器缓存，然后看下error.log 和 access.log。

Answer 2

nginx没有支持PHP解析:

你百度下 nginx.conf 配置文件对PHP的支持

location ~ .php$ {

<code>           root /usr/local/nginx/html; #指定php的根目录
           fastcgi_pass 127.0.0.1:9000;#php-fpm的默认端口是9000
           fastcgi_index index.php;
           fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
           include fastcgi_params;
    }</code>
