nginx 配置php访问

nginx中配置可访问php文件，并实现php  pathinfo。nginx.conf配置文件如下：

server {
   listen 8080 default_server;
   listen [::]:8080 default_server ipv6only=on;

   root /var/www/html;
   index index.html index.htm index.php;
        autoindex on;
   autoindex_exact_size off;
        autoindex_localtime on;  
   # Make site accessible from http://localhost/
   server_name localhost;

   location / {
      # First attempt to serve request as file, then
      # as directory, then fall back to displaying a 404.
      try_files $uri $uri/ =404;
      autoindex on;
           # Uncomment to enable naxsi on this location
         if (!-e $request_filename) {
         rewrite ^/(.*.php)(.*)$ /(.*.php)?s=$1 last;
         rewrite ^(.*)$ /(.*.php)?s=$1 last;
         break;
        }
    }

      location ~ \.php$ {
      #root     ;
                try_files $uri = 404;
                 fastcgi_split_path_info ^(.+\.php)(/.+)$;
                 fastcgi_split_path_info ^(.+\.php)(.*)$;
                 fastcgi_param PATH_INFO $fastcgi_path_info;
                 fastcgi_pass unix:/var/run/php5-fpm.sock;
                 fastcgi_index index.php;
                 include fastcgi_params;        
                set $path_info '';
               set $real_script_name $fastcgi_script_name;
               if ($fastcgi_script_name ~ "^(.+?\.php)(/.+)$") {
                     set $real_script_name $1;
                     set $path_info $2;
               }
               fastcgi_param SCRIPT_FILENAME /var/www/html/$real_script_name;
               fastcgi_param SCRIPT_NAME $real_script_name;
               fastcgi_param PATH_INFO $path_info;
        }  

    location ~ /\.ht {
        deny all;
    }
}
