thinkphp5在nginx环境下运行的时候默认是不支持通过index.php/index/index/index的形式去访问的，也不支持route，所以需要手动配置nginx使其支持。
apache默认支持

修改nginx的配置文件

1. 找到你的thinkphp站点配置项，在其中的php项中如同下面配置

   • windows

     location ~ \.php(.*)$  {
         fastcgi_pass   127.0.0.1:9000;
         fastcgi_index  index.php;
         fastcgi_split_path_info  ^((?U).+\.php)(/?.+)$;
         fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_script_name;
         fastcgi_param  PATH_INFO  $fastcgi_path_info;
         fastcgi_param  PATH_TRANSLATED  $document_root$fastcgi_path_info;
         include        fastcgi_params;
     }

   • linux

     location ~ \.php(.*)$  {
         fastcgi_pass   unix:/run/php/php7.0-fpm.sock;
         fastcgi_index  index.php;
         fastcgi_split_path_info  ^((?U).+\.php)(/?.+)$;
         fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_script_name;
         fastcgi_param  PATH_INFO  $fastcgi_path_info;
         fastcgi_param  PATH_TRANSLATED  $document_root$fastcgi_path_info;
         include        snippets/fastcgi-php.conf;
     }

2. 使nginx支持thinkphp5路由

   location / {
           index  index.php index.html index.htm;
           #如果请求既不是一个文件，也不是一个目录，则执行一下重写规则
           if ( !-e $request_filename) {
               rewrite ^(.*)$ /index.php/$1 last;
               break;
           }
       }
