I just can’t run Laravel 5 in php7-fpm, nginx on Debian 8, who understands this?

Question

PHP

I want to run laravel in sub directory
My host config

server {
        listen 80;
        server_name localhost;
        root /usr/share/nginx/html;
        index index.php index.html index.htm;

# Redirect server error pages to the static page #
        location / {
      try_files $uri $uri/ /index.php;
        }
      error_page 404 /404.html;
      error_page 500 502 503 504 /50x.html;
        location = /50x.html {
      root /usr/share/nginx/html;
        }

# Pass the PHP scripts to FastCGI server #
        location ~ \.php$ {
      try_files $uri =404;
      fastcgi_pass 127.0.0.1:9000;
      fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
      fastcgi_index index.php;
      include fastcgi_params;
       }
# phpmyadmin	   
    location /phpmyadmin {
        alias /usr/share/phpmyadmin;
    }

    location ~ ^/phpmyadmin(.+\.php)$ {
      alias /usr/share/phpmyadmin;
      fastcgi_pass 127.0.0.1:9000;
      fastcgi_index index.php;
      fastcgi_param SCRIPT_FILENAME /usr/share/phpmyadmin$1;
      include fastcgi_params;
    }

    location ~ ^/phpmyadmin/(.*\.(eot|otf|woff|ttf|css|js|jpg|jpeg|gif|png|ico|zip|tgz|gz|rar|bz2|xls|tar|bmp))$ {
      alias /usr/share/phpmyadmin/$1;
      expires 30d;
      log_not_found off;
      access_log off;
    }

# Laravel	
    location ^~ /laravel {
      alias /usr/share/nginx/html/laravel/public;
      try_files $uri $uri/ @laravel;
      
      location ~ \.php {
        try_files $uri /index.php =404;
        fastcgi_split_path_info ^(.+\.php)(.*)$;
        fastcgi_pass 127.0.0.1:9000;
        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
        fastcgi_index index.php;
        include fastcgi_params;
      }
    }

    error_log  /var/log/nginx/seriesadmin-error.log error;
    
    location @laravel {
      rewrite /laravel/(.*)$ /laravel/index.php?/$1 last;
    }
  }

When I switch to xx.xx.xx.xx/laravel, I get File not found.
the following in the logs:

2016/08/08 19:08:28 [error] 1268#1268: *3 FastCGI sent in stderr: "Primary script unknown" while reading response header from upstream, client: 109.163.234.7, server: localhost, request: "GET /laravel/ HTTP/1.1", upstream: "fastcgi://127.0.0.1:9000", host: "81.171.2.119"

If you delete

fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;

from the config, displays a pure white page.
As I understand the problem lies in php, but I can not understand where (

location ^~ /laravel {
                        alias /usr/share/nginx/html/laravel/public;
                        try_files $uri $uri/ @laravel;

                        location ~ \.php {
                                root /usr/share/nginx/html/laravel/public;
                                try_files $uri /index.php =404;
                                fastcgi_split_path_info ^(.+\.php)(.*)$;
                                fastcgi_pass 127.0.0.1:9000;
                                fastcgi_index index.php;
                                fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
                                include fastcgi_params;
                        }
                }

                location @laravel {
                        rewrite /laravel/(.*)$ /laravel/index.php?/$1 last;
                }

"File not found." writes php-fpm if it cannot find the file with the script.
try setting @laravel location to "root"
