环境:centos7,yum安装的nginx1.10、php-fpm,tp3.2 
本方法只需要配置nginx.conf的一个文件就可以支持pathinfo和rewrite两种url访问方式

vim /etc/nginx/nginx.conf

1、支持rewrite方式: 
在 location / 处添加以下代码

if (!-e $request_filename) {

   rewrite  ^(.*)$  /index.php?s=$1  last;

    break;

}

最终变成

location / {

            root   html/code;

            index  index.php index.html index.htm;

            if (!-e $request_filename) {

                rewrite  ^(.*)$  /index.php?s=$1  last;

                break;

            }

        }

2.实现pathinfo模式 
找到有效的 location ~ .php$那部分 
首先,将这个$去掉， 
然后里面添加以下两行代码

fastcgi_split_path_info ^(.+\.php)(.*)$;

fastcgi_param PATH_INFO $fastcgi_path_info;

最终变成

location ~ \.php {

            root           html/code;

            fastcgi_pass   127.0.0.1:9000;

            fastcgi_index  index.php;

            fastcgi_split_path_info ^(.+\.php)(.*)$;

            fastcgi_param PATH_INFO $fastcgi_path_info;

            fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_script_name;

            include        fastcgi_params;

        }

3.重启nginx和php-fpm即可使用了

service nginx restart

service php-fpm restart

本地phpstudy修改实例:

 nginx.conf

         root   "D:/WWW";

         location / {

             index  index.html index.htm index.php l.php;

            autoindex  on;

            #add  rewrite

            if (!-e $request_filename) {

                 rewrite  ^(.*)$  /index.php?s=$  last;

                 break;

             }

         }

         location ~ \.php(.*)$  {    //这边$去掉试试

             fastcgi_pass   127.0.0.1:;

             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;

             #add pathinfo

             fastcgi_split_path_info ^(.+\.php)(.*)$;

             fastcgi_param PATH_INFO $fastcgi_path_info;

         }
